RESTORATION OF CHILDREN’S TEETH: THE JOURNEY FROM MINIMAL INTERVENTION
TO PULP THERAPY
Prof. MONTY DUGGAL
Sadly, despite an impression of an improving oral health on a global population level, large numbers of children seek the care from dentists and paediatric specialists for severe dental caries. Even wealthy countries
have been unable to purge the population of this most common disease of childhood. This has put strain on
the health budgets and many governments have been asking the health professionals to seek approaches to
providing care for these children at minimal cost. In some countries this has lead to developing a philosophy
of “supervised neglect” of dental caries, with problems dealt with as and when they occur. In some European
countries such as the UK and increasingly Ireland and Netherlands debates are raging whether primary teeth
should be filled at all, and if so what might be the most cost effective approach to this. The speaker is a fervent advocate of high quality restorative dentistry to go hand in hand with preventive approach for children.
However, treatment planning for children cannot be a “one shoe fits all” approach, and has to take into account
individual social, behavioural and economic considerations. Some children will benefit from minimal intervention approach, together with an intensive preventive programme. Some will need comprehensive dental
care, including pulp therapy and coronal restorations and also multiple extractions. The speaker will try and
discuss these approaches and where they may be applicable making an attempt to be evidence based and on
a firm scientific footing. We should all be aware that in the current global economic climate when all governments and individual people are tightening their belts it is our duty as paediatric dentists to uphold highest
possible care for children, but not to be intransigent and oblivious to evidence based dentistry in our quest to
do what we have been trained to do. This lecture will aim to be thought provoking aimed at generating a discussion that is bound to land at the doorstep of every paediatric dentist in this world sooner rather than later.

DENTAL PULP STEM CELLS AND DENTAL TISSUE REPAIR: TOWARDS REGENERATIVE
DENTISTRY
Professor Alastair J Sloan
Head, Tissue Engineering & Reparative Dentistry, School of Dentistry, Cardiff University,
It is widely accepted that progenitor / stem cells reside within the post-natal dental pulp and studies suggest
several niches of mesenchymal progenitor cells known as dental pulp stem cells may be present in the tissue.
These progenitor cells are essential for dentine regeneration following injury, leading to the formation of
reparative dentine. Understanding the nature of these progenitor cell populations, their ability to function in
highly compromised environments and determination of their potentialities in terms of specificity of regenerative response may help direct new clinical treatments including the development of biologically based new
generations of ‘smart’ clinical materials for controlled direct recruitment of the cells in situ. In addition, such
understanding is important for the development of isolation or recruitment strategies for use in tissue engineering such as seeding of stem cells at sites of injury for regeneration or use of the stem cells with appropriate
scaffolds to direct tissue repair processes. This lecture will explore the thoughts on the functional biology of
the dental pulp stem cells and how they may be harnessed to enhance tissue repair clinically.
8
MOLAR-INCISOR HYPOMINERALISATION (MIH) AND COMMON DENTAL ANOMALIES
SEEN IN GENERAL DENTAL PRACTICE
Prof. MONTY DUGGAL
The prevalence, presentation, aetiology and the management of a new condition known as Molar-Incisor
Hypomineralisation (MIH) will be discussed. This presents as soft, yellow and hypersensitive first permanent molars and demarcated opaque defects of central incisors. The most challenging issues for the GDP is
managing the acute sensitivity from these teeth, followed by their immediate, intermediate and long term
management. The aetiology, pathophysiology and histology of MIH will be reviewed based on recent and
new evidence. Common dilemmas in treatment planning for the clinicians will be highlighted. The use of
composites for restoration of anterior defects and the use of both SSC’s and lab formed restorations for the
molars will be also be discussed. Also, the technique of microabrasion will be explored as an effective way of
improving the aesthetics for hypomineralisaed permanent incisors in adolescents and young adults.

FULL CERAMIC RESTORATION, THE NEW ERA IN PEDIATRIC DENTISTRY
Dr Osama El Shahawy
Associate Professor of Pediatric Dentistry Cairo University
Head of Pediatric Dentistry Department Future University, Egypt
Successful & reliable restoration of primary teeth is a cornerstone in managing pediatric dental defects. Restoration is essential to manage small cavities all through severely mutilated teeth. The longevity and reliability
of the restoration fulfilling function and esthetics demands is the goal of all pediatric dental practitioners.
As it is well known, Full coverage is the reliable restorative option for endodontically treated teeth, severely
mutilated teeth and teeth with developmental defects. Moreover recent conservative approaches in management of deep caries requires proper restorative seal to ensure the success of indirect pulp capping or partial
caries removal, and this can well achieved with full coverage.
Veneered stainless steel crowns emerged as an esthetic alternative to the classic stainless steel crowns. Most
recently, full ceramic zirconium crowns were introduced both for anterior and posterior restorations as a superior esthetic option with perfect gingival integration and thus adding a new dimension in restoring primary
teeth.

TRAUMA IN CHILDREN AND ADOLESCENTS WITH EMPHASIS ON NEW MATERIALS,
DEVELOPING SCIENCE AND MULTIDISCIPLINARY MANAGEMENT
Prof. MONTY DUGGAL
This talk will cover two areas. Firstly interdisciplinary care for children with severe dentoalveolar trauma
will be presented. Secondly the speaker will outline a detailed critique of regenerative endodontic procedures.
The speaker will outline his treatment philosophy for the management of young permanent teeth which have
suffered trauma resulting in injury to the pulp, resulting in the pulp becoming non vital before the root development is completed. . The emphasis of the course is to provide an update on the current approaches that
should be based on knowledge of cellular biology. Any attempt to provide treatments without an understanding of the tissue responses to injury or treatment are doomed to failure. Traditional approached have
involved Apexification with the use of calcium hydroxide. Calcium hydroxide has many advantages but also
there is a growing body of evidence on its detrimental effects on the integrity of dentine and dentinal proteins.
Mineral Tri-oxide Aggregate has also been recently used, its main advantage being that it allows a barrier to
be formed immediately, so that root canal obturation can be achieved. The speaker will discuss some disadvantages associated with MTA owing to its alkalinity, which is similar to that of calcium hydroxide. Recently
a lot has been written about the use of stem cells for regeneration of the pulp for non vital immature teeth.
This approach which is termed as Regenerative Endodontics seems to offer a new biological approach, which
would allow root development, but is largely untested and lacking evidence from clinical studies. Now that
we have some experience with the use of this technique it has become clear that the early optimism regarding
its success was ill founded. The outcomes for this technique continue to be unpredictable and still there is
little evidence to support its use into the future. The main issue that the speaker has found in his research is the
unpredictability of the outcomes when it is used to treat teeth with trauma as opposed to teeth with developmental anomalies, such as dens-in-dente. The role of the root sheath of Hertwig has largely been ignored and
the speaker will discuss the important role of this structure in the outcome of this technique. Future directions
will have to be to develop scaffolds and signalling molecules and this will be elaborated.
We have developed a multidisciplinary approach for the management of anterior teeth with poor prognosis as
a result of dental trauma. This involves bone management at the affected site followed by autotransplantation.
Since the inception of this programme we have placed over 160 transplants using the multidisciplinary team
comprising of both paediatric dentistry and orthodontic expertise. This talk will aim to provide an overview of
the relationship between dental trauma and orthodontic practice and discuss the technique of transplantation,
management of bone in areas where teeth are lost as a result of trauma and the requirements for pre-transplant
and post-transplant orthodontics.
Objectives to enable the participants
- to understand the impact of previous trauma
- the role of orthodontics in treatment of traumatized teeth of poor prognosis
-the role interdisciplinary care in dental Traumatology
- management of bone when loss of tooth is inevitable
- rationale and outcomes for tooth transplantation in children.

Aim: The aim of this study was to investigate the biocompatibility of five different fluoride agents [1.23%
Acidulated Phosphate Fluoride(APF) and 2% Sodium Fluoride(NaF) gels, 1% Titanium Tetrafluoride(TiF4)
and 38% Silver Diamine Fluoride(SDF) solutions and Duraphat Fluoride Varnish containing 5% NaF] which
are thought to cause toxic effects on oral mucosal tissues by using cell culture method.
Methods: For this purpose, L929 mouse fibroblast cell lines and human gingival fibroblast cell lines obtained
from healthy individuals were used. Cytotoxicity of the agents was analyzed by using the real time xCELLigence System Analysis. Apoptosis is evaluated by using Annexin V and TUNEL test methods. For statistical
evaluation, linear regression analysis was used to compare the toxicity of fluoride agents. The data obtained
from apoptosis was evaluated statistically by using chi-square test and Fisher\’s Exact test.
Results: The lowest cytotoxic effect was observed with NaF in L929 mouse fibroblast cell line and with APF
in human gingival fibroblasts. NaF significantly increased apoptosis in L929 cells however no significant difference was found between the control and the study groups in gingival fibroblast cell line. APF was observed
to have significant effect in inducing apoptosis in L929 cells but no significant apoptotic effect was observed
in gingival fibroblast cells (p>0,05). TiF4 showed high cytotoxicity in both L929 and gingival fibroblasts.
Silver diamine fluoride solution did not show any significant apoptotic effect in both L929 cells and gingival
fibroblasts (p>0,05). In both cell lines, NaF, APF gels and silver diamine fluoride were recorded as less cytotoxicty compared to TiF4 solution and Duraphat fluoride varnish.
Conclusion: Silver diamine fluoride which is a quick and effective treatment procedure for arresting caries,
preventing the formation of early enamel caries lesions in disabled and non-cooperated children can be recommended as an alternative to commonly used APF

Aim: The aim of our study was to evaluate the effect of a herbal lollipop containing licorice root extract, on
salivary S. mutans in caries free and high caries risk children.
Methods: Study has been carried out in 108 children (5-11 aged). Groups were consisted of caries free children
(group A, n=36); children with high caries risk, whose dental treatment completed before lollipop use (Group
B, n=36) and children with high caries risk, who did not comply with dental treatment (group C, n=36).
Groups were divided into two subgroups according to lollipop types (herbal and placebo lollipops). Saliva
samples were taken before dental treatment in group B; before and after consuming lollipops, and at the end
of the third month in all groups, to determine the level of S. mutans using ‘Dentocult SM Strip Mutans test’.
The results were statistically analyzed with Wilcoxon signed-rank and Mann-Whitney U test.
Results: In all groups except C-1, there was no statistically significant difference between before and after
lollipop use, in the levels of salivary S. mutans (p>0,05). Only in the group of children, using herbal lollipop,
with high caries risk who did not have dental treatment, salivary S. mutans levels showed significant reduction
(p<0.05). In the group who completed dental treatment, salivary S. mutans counts were decreased significantly
after the treatment (p<0.05). At the third month control, in caries free children using placebo lollipops and
children using herbal lollipops with high caries risk who had dental treatment, S. mutans levels were found to
be significantly higher (p<0.05). There were no significant differences in other groups (p>0,05).
Conclusions: Herbal lollipops containing licorice root extract significantly reduced salivary S mutans levels in
children with high caries risk and who do not comply with dental treatment.

Aim: This study aimed to investigate the effect of acidulated phosphate fluoride (APF) gel and casein phosphopeptide/amorphous calciumphosphate (CPP-ACP) on the dental erosion produced by Coca Cola in primary
teeth.
Methods: This study evaluated by an in vitro model the effect of APF gel and CPP-ACP on the dental enamel
previously subjected to erosive challenge with Coca Cola. Sixty sound human primary molars were prepared
by embedding the crown sections in acrylic resin blocks leaving the enamel surfaces exposed. The surface
roughness of the enamel was measured with prophilometry at baseline. Specimens were randomly divided into
three treatment groups (n:20): artificial saliva, CPP-ACP, 1.23% APF gel. All specimens were then exposed
to an erosive challenge of coca cola soft drink and artificial saliva for 20 cycles of 20 seconds each. Demineralization-remineralization cycles was repeated twice at eight-hour intervals and roughness values were
measured. Enamel samples were treated with artificial saliva, CPP-ACP, 1.23% APF gel applied for 10 min
after erosive challenge. the arithmetic average roughness (Ra) readings were recorded after remineralization
agents were applied.
Results: The mean surface roughness in all groups increased significantly after erosion process and decreased
after remineralization treatment. After treatment, the mean surface roughness of the 1.23% APF gel group
was significantly less than the other groups and the mean surface roughness of the artificial saliva group was
significantly more than the other groups. 1.23% APF gel showed the highest protective effect against erosive
enamel loss.
Conclusions: Under the conditions of this study, artificial saliva, CPP-ACP and 1.23% APF treatments were
able to reduce erosive enamel loss produced by Coca Cola in primary teeth. However, 1.23% APF gel showed
the highest protective effect against erosive enamel loss.

Introduction: Mother’s as primary caregivers are directly responsible for the dental health of their offspring
and can play an important role in preventing oral diseases in children.Understanding factors in mothers associated with high and low salivary levels of cariogenic bacteria is an important strategy for early childhood
caries prevention. Aim: Aim of the study was to identify the association between salivary levels of cariogenic
bacteria and validated caries risk factors generated from questionnaire.
Method: 300 mothers of young children (child aged of 12 months or younger)took part voluntary in the survey. They were recruited at the vaccination center while they brought their child for vaccine. The presence of
cariogenic bacteria Streptococcus mutans and Lactobacillus in saliva was determined using the CRT bacteria
test (Ivoclar Vivadent). Closed simple questions and observations were used to test the mother’s attitude and
caries experience.
Results: Our results showed high levels of infection with Streptococcus mutans and Lactobacillus among
mother’s (28 %). Participants were more highly infected by Streptococcus mutans (28.0%) than with Lactobacillus (19.7%).Three factors were significantly associated with Streptococcus mutans infection: level of
education, anterior caries experiences and observable dental plaque. A fourth factor - frequency of daily tooth
brushing – showed to be associated to Lactobacillus infection.
Conclusion: The study showed that easy collected factors such maternal level of education and anterior clinical factors can be associated to mother’s highly infected with Streptococcus mutans and Lactobacillus.

Aim: The most common and successful methods used in the prevention of dental caries are fluoride applications. Varnishes are the vehicles most frequently used for topical fluoride applications with evidence on
effectiveness in prevention of dental caries. Drugs can be formulated for long-term controlled release when
polymers are added to the various carriers. PVA is a water soluble, non-toxic, biocompatible polymer, recently
used in a variety of fields in medicine, because of its high physical properties, excellent adhesion to tissues and
materials beside good chemical and thermal stability.The aim of the present study was to evaluate the effect of
fluoride tapes prepared using different concentrations of PVA on inhibiting demineralization of bovine enamel
in comparison with a %5 fluoride varnish in vitro.
Methods: Sixty enamel specimens (3*3mm) were prepared from extracted bovine incisors. Samples with
surface microhardness ranging from 340-380 Vickers Hardness Number (VHN) were pooled and randomly
assigned to five groups: control group, F-varnish group, 8%, 10%, 12% F-PVA groups. After applications of
agents in each group the pH-cycling was processed. Then VHN was measured and the percentage loss of surface microhardness (SML%) was calculated.
Results: Surface VHN values determined after pH-cycling were found to be significantly lower than the baseline values in the control and experimantal groups (p<0,0001). The difference between the groups was found
statistically significant. The surface VHN values in the experimental groups were significantly higher compared to the control group (p=0,0001). Also, the SML% rates were calculated lower in the experimental groups
and the difference was statistically significant (p<0,0001).
Conclusion: Fluoride tapes prepared with different concentrations of PVA were found to be effective in prohibiting enamel demineralization in vitro. The preventive effects of experimental F-PVA groups were determined to be comparable to the 5% flouride varnish (Duraphat®).

Aim: As Ankara University Faculty of Dentistry/Youth Activist Group we are carrying out a youth initiative
project in Ankara University Faculty of Dentistry. The aim of this project is to create an educational model that
would make children of 5-7 age, their parents and teachers realize the importance of oral health.
Methods: We have taken the opinions of many pedagogues and pediatric dentists while we are creating this
educational model. Main difference of our model is that it includes creative drama. The teaching phase is
never a “plain explanation”, but one that makes the children learn by through the games they play. And an additional conference is given to the parents after the education of children. Looking at the faculties of dentistry
in Turkey, we can see that there are a lot of preclinic students. At this phase these students has no contribution
to society. But with our education module it’s proven that these students may contribute to society as well. We
included universities in Holland and Croatia since the member countries of European Union is more experienced and advanced in oral health than Turkey. By this way we are willing to use their experiences and at the
same time we create a cultural interaction with the students of dental faculties in different countries.
Conclusion: In the upcoming process, we will use our module on more children and support our module with
some datas and surveys before and after the process.

Aim:The aims of the present study were to describe the characteristics of children receiving comprehensive
dental rehabilitation under general anesthesia (DRGA) at dental hospital in Turkey, and to evaluate dental
treatment patterns and waiting times between examination and receiving GA for these children. The authors
described the characteristics of children receiving comprehensive DRGA at a dental hospital in Turkey.
Methods:A total of 441 patients’ records were included and were composed of 272 (61.7%) boys and 169
(38.3%) girls. Although most of the children (159, 54.1%) were aged between 3 and 5 (mean: 5.40 ± 2.00)
years in the healthy children group (Group I), most of the special needs children (Group II) (85, 55.5 %) were
aged between 6 and 11 years old (mean: 6.93 ± 3.13). Extreme non-cooperation, dental fear, and an excessive
need for treatment were the major reasons for the use of comprehensive dental treatment under GA.
Results and Conclusion: The mean waiting times for treatment under GAwere significantly shorter inASAIII,ASA
IV and disabled children in ASA I and ASA II, compared to physically and mentally fit ASA I and ASA II children.

Introduction: The oral hygiene is the main component of the oral health. It has an impact on collection of
dental plaque and consequently the appearance of caries with all the possible consequences. Dental plaque organisms are not only the main causes for oral pathologies, but also for Bacterial Endocarditis (BE) at children
with Congenital Heart Diseases (CHD).
Aim: The aim of this study was evaluation of oral hygiene, the level of dental plaque streptococci and the
correlation between them in children with CHD.
Material and methods: The study includes 90 children divided in the group of healthy children (n=30) as a
control group and group of Children with CHD (n=60) as a study group. The children included in this research were of both genders, age 6 through 15 years. The evaluation of oral hygiene was done according to
Greene-Vermillion OHI-idex, whereas the level of streptococci from dental plaque (DP) was determinate by
CFU-method (colony forming unit) with the value of <102, 102-3, 104-5 and >105.
Results: The study provides indications for poor oral hygiene for both groups of children without significant
differences (P>0.05). The value from 1.1-2.0 was found in the high percentage in children whith CHD (45%),
while the value 0 only in two of them. Regarding to level of DP streptococci in the study group, 15% of cases
CFU was 102-3, 31.7% was 104-5 and 51.7% CFU>105 . The correlation between oral hygiene index and
level of dental plaque streptococci was significant for both groups (P<0.01).
Conclusion: Based on the results of our research we can conclude that children with CHD have the poor oral
hygiene and the high level of dental plaque streptococci that may have consequences on the overall health.

Aim: The aim of the study was to evaluate the effects of gluten-free diet on the oral findings of celiac disease
Methods: The study was approved by the Ethical Committee of Ege University. Sixty-three children aged 3 to
19 years with the diagnosis of CD at least two years, 34 newly diagnosed and 35 healthy children of the same
age participated in the study. Enamel defects were diagnosed and classified by Aine’s classification. A questionnaire related to medical history, diet , oral hygiene habits and use of fluoride was carried out to all subjects.
The soft tissues were examined for the diagnosis of Recurrent Apthous stomatit (RAS) and the patients were
also questioned about the recurrence of oral ulcers. All data were analyzed using t-test, chi2-test ,NPar Test
and Mann-Whitney U-tests.
Result: The enamel defect prevalence was significantly higher in both CD group( %63,9). The patients who
were newly diagnosed had more dental enamel defects than the other celiac group, but the difference was not
significant(p=0,609). RAS was observed to be statistically higher in the group of newly diagnosed(p=0,016).
The prevalence of RAS decreased 69% of celiac patients after gluten-free diet. Sugar intake was found statistically higher in both newly diagnosed patient group and healthy group(0,008). The frequency of tooth-brushing
was higher in the group of celiac patients under gluten-free diet.
Conclusion: This investigation has shown that gluten-free diet acts an important role on developing enamel
defects and RAS. Restricted on gluten-free diet gives children more responsibility on their whole life and a
good care of themselves.

Aim: This multi centered study aimed to evaluate the prevalence and potential etiological factors involved in
the development of Molar Incisor Hypomineralization (MIH) based on data from 4 cities of Turkey namely,
Ankara, Istanbul, Izmir and Samsun.
Methods: A total of 8867 children aged 7-13 years participated in the study. Dental examinations were done
under school circumstances by calibrated dentists. The crowns of the first permanent molars (FPMs) and
permanent incisors (PI) were examined according to European Association of Pediatric Dentistry diagnostic
criteria. Children were considered to have MIH, if one or more FPM with involvement of at least one or more
incisors were hypomineralized. Consent forms and surveys were sent to student’s families to evaluate medical
history, demographic and pregnancy related information.
Results: MIH showed a prevalence of 7% in Turkey. There was a statistically significant difference in MIH
prevalence among the centers (p=0.00). Istanbul had the highest prevalence with 11.9% which was followed
by Ankara 7.7%, Samsun 5.2%, and Izmir 3.1%. The prevalence of MIH was found to be associated with
childrens’ low birth weight, asthma, high fever resulting in convulsions, pneumonia, chronic renal failure and
severe diarrhea story during the first four years of life (p=0.00). Occurrence of measles, chicken pox and scarlet fever before the age of 4 was also found to be associated with MIH.
Conclusion: Present study underlined the potential etiological factors of MIH in Turkey. Families and children must be informed by their pediatricians for the risk of MIH. Children under this risk group must be
followed up by pedodontists since preventive approaches are very important at an early developmental age.

OBJECTIVE: Dental caries is a major oral health problem in most countries affecting 60 – 90 % of junior
high school children. The aim of this study was to evaluate the dental status of 15-year ld children in Prishtina
region, in urban and rural areas.
MATERIALS AND METHODS: We have included 200 schoolchildren at the age of 15 (88 male and 112
female), residents of Prishtina region, from the urban and rural areas. Study was carried out at the University
Dental Clinical Center of Kosovo, patients were randomly selected. Participants from urban areas was 45
(22.5%) male; female 67 (33.5%) and from the rural regions male 43(21.5%) and 45 female schoolchildren
(22.5%). The dental caries prevalence and intensity among schoolchildren were calculated using DMFT index
following WHO guidelines.
RESULTS: The prevalence of dental caries among 200 schoolchildren enrolled was 84.5% while 15.5% were
caries free, whereas mean DMFT value was 3.89, while 23.1 % decayed teeth 3.8 % missed teeth and 12 %
filled teeth. Based on gender, caries prevalence among female was 64 % and 36% among male subjects. Mean
DMFT was higher than 0 (DMFT>0 ) for urban schoolchildren was 56.37% compared to rural schoolchildren
(43.63%).
CONCLUSION: We have concluded that Prishtina region schoolchildren have high caries prevalence. Preferred preventive approach is more than necessary for urban schoolchildren due to higher caries prevalence, related
to their diet and poor oral health maintenance. Furthermore, regular teeth controls are strongly recommended.

Introduction: A friendly smile is the most important element in creating a first good impression. People who
have beautiful teeth are considered more attractive. They have more self confidence, self esteem, they are better accepted socially and they are more successful academically. A childs’s smile reveals their quality of their
life. Children with concerns over their smiles show less security. They avoid smiling, they cover their mouth
when they do. They feel inferior to other children. Unaesthetic smile has a deep impact on their life. Aim: The
aim of this study was to investigate the impact of childrens front teeth and their smile on their psychological
state.
Material and methods: Children of various ages were interviewed. We selected children most affected by their
unaesthetic smile. Their teeth were treated, restored, improved their aesthetics and their psychological state
was carefully monitored by the psychologist before and after the treatment.
Results: Children with unaesthetic smile showed low self confidence, low self esteem and isolation, depression which affected their social and academic performance. After the treatments, they showed improvements in
all the areas. They highlighted the joy of freedom to smile with the mouth open.
Conclusion: It is very important to educate parents and children to put more effort on oral hygiene, to treat and restore
their teeth, prevent them from experiencing this impact of unaesthetic smile on their psychological development.

EVALUATION OF STRESS DURING DENTAL EXTRACTIONS-A CORRELATION STUDY
Vivek PADMANABHAN, Ras Al Khaimah College Of Dental Sciences - Pediatric Dentistry
Introduction: Dental environment may be a source of stress for young children. Such stressful conditions
may provoke fear and anxiety in children. Therefore stress factor is high in children visiting dentists and this
stress may increase or decrease in the subsequent visits that follow dependent upon to what they are exposed
to, during these visits especially high anxiety provoking procedures like dental extractions. Cortisol, called
also “stress hormone” participates in organism’s response to stress situations and enters into complex interactions with the hormonal and immune system of a man.
Methodology: The salivary cortisol levels were investigated in 60 children who were divided into study and
control groups respectively. The control group was not subjected to any treatment except for collection of saliva. Children belonging to the study group were subjected to dental extraction as indicated and were performed
in three scheduled appointments.
Saliva samples were collected from all the children during all the appointments. Modified dental anxiety
scales were also used during each of the appointments. Salivary cortisol levels were evaluated using the ELISA kit supplied by Salimetrics.
Results:The results indicated that the salivary cortisol levels increased in the study group when compared to
the control groups and within the study group the salivary cortisol levels in the second appointment were on
a higher level when compared to the first and third appointments and the results were statistically significant
(p<0.005)
Conclusions: the results show that there is a positive correlation between anxiety scale measurements and
salivary cortisol levels.

ORTHODONTIC PREVENTION, INTERCEPTION AND TREATMENT IN THE MIXED
DENTITION WITH SILICONE ACTIVATOR
Dr. NEVİN ASAL
The fully developed deciduous occlusion provides a good prediction for how the occlusions will develop in
the future. Because malocclusions tend to become more severe as the dentition develops during the mixed
dentition, intervention in the mixed dentition is even more beneficial (Ingelsson-Dahlsröm M and Hagberg
C, 1994). For patients with class II malocclusion and deep bite this timing may provide better stability. The
profile and lip closure improve as well as the risk of incisor trauma reduces (Nguyen QV et al, 1999; Järvinen
S, 1978).
Functional appliances have been frequently used for more than a century for treatment of Class II division 1
malocclusions. The principal aim of dentofacial orthopedic treatment is to correct the dental arch relationship
and to promote favorable mandibular growth changes (Andresen and Häupl, 1945). One of the essential benefits which is attributed to the treatment of Class II malocclusions is prevention of trauma to maxillary incisors
associated with the large overjet (Järvinen S, 1978; Shulman JD, Peterson J, 2004).
Various improvements in the design of functional appliances have been introduced to attain better effectiveness and patient acceptance. An important characteristic of Class II functional appliances is the constriction
bite that positions the mandible anteriorly to enhance mandibular growth (Moore et al, 1989).
Dental impression on small children is often difficult for the dentist and unpleasant for the child (Rosted P. et
al, 2006; Landgren R.). We don´t like to give rise to dental fear due the orthodontic process. Bite registration
is an intricate and time-consuming task for many general practitioners. The manufacturing process requires a
lot of time with multiple visits to the dentist and loss of income for the parents.
Prefabricated functional appliances, just like removable dental appliances, are considered to be complementary (Keski- Nisula K et al 2008; Usumez et al 2004) to the traditional functional appliances (Calvert FJ et
al 1982; Nielsen IL et al 1991). The former is prefabricated and only one measurement of dental-arch size is
needed to find the right size. There is no need for dental impression or bite registration. Prefabricated eruption
guidance appliances are effective in correcting increased overjet and overbite and have the advantage in regards to lesser fabrication costs, shorter chair-time and patient comfort (Keski-Nisula,K et al, 2008).

ORTHODONTICS- PEDODODONTICS INTERFACE
Prof.Dr. Koray GENÇAY
The pediatric dentist and orthodontist share many professional interests by virtue of the fact that they both
are guiding the eruption and development of dentition. It is important to differentiate between a developing
normal occlusion and a potential malocclusion, with an understanding of general physical maturation of the
growing child by pediatric dentist is also essential. Because of this reason, pediatric dentists should have the
responsibility to recognize, diagnose, and either appropriately manage or refer abnormalities in the developing
dentition. The objectives of intervention/treatment may be classified as preventive or interceptive, and include
reducing adverse growth, preventing increasing dental and skeletal disharmonies, managing ectopic tooth
eruptions, applying serial extractions, improving esthetics of the smile, and improving the occlusion. As the
potential synergistic collaboration of the pediatric dentistry and orthodontics, combined academic and clinical
interests in these disciplines are linked increasingly to solve problems in the child and adolescent patient.
This lecture aims, therefore, to address a range of common clinical problems encountered in pediatric dentistry
and orthodontic dental practice.

CONGENITAL AGENESIS OF MANDIBULAR SECOND PREMOLARS: ETIOLOGY,
PREVALENCE, DIAGNOSIS, TREATMENT PLANNING
Prof. Dr. ŞAZİYE SARI
Agenesis of permanent teeth is an important clinical and public health problem. Hypodontia is the term used
to describe the developmental absence of one or more primary or permanent teeth. It is one of the most common developmental dental anomalies in humans and is an important clinical and public health problem. The
prevalence varies among different ethnic groups ranging from 2.5 to 15.68%. Dental agenesis affects more
frequently the permanent rather than the primary dentition and is often seen in mandible. Furthermore, mandibular second premolars are the most frequently affected teeth (41.0 %) excluding third molars. Unilateral
occurance of second premolars is more common than bilateral occurance.
The condition may appear as part of a recognized genetic syndrome or as a non-syndromic, familial form,
which occurs as an isolated trait.
Clinically, persisted primary second molars may be in occlusion or become infraoccluded resulting in loss of
vertical and sagittal space because of the movement of adjacent or opposite teeth. Usually these retained teeth
are ankylosed. Radiographically, persisted primary molars may have resorption as healthy as can be.
For the treatment planning the age of the patient, condition of the retained teeth and supporting tissues, occlusion and interocclusal rest space must be taken into account.
The treatment options varies from the extraction or programised extraction of retained primary second molars
to keep them in the mouth. In general, care requires a team approach, including pediatric, orthodontic, restorative specialist and oral surgeon.

Adem KUSGOZ, Karadeniz Technical University, Faculty of Dentistry - Pediatric Dentistry,
Mehmet TANRIVER, Sifa University, Faculty of Dentistry - Pediatric Dentistry,
Aim: This clinical study compared the retention rates of a nanofilled (Grandio seal) and conventional (Clinpro)
occlusal fissure sealant placed with different enamel preparation over 56 months.
Methods: The study was planned as a clinical trial with a split-mouth design. The authors enrolled 104 teeth,
each with no restoration or sealant and no detectable caries, from 30 patients. These children has been randomly separated into two groups: A case group (mechanically preparation of enamel) and a control group (conventional method,without preparation). After applying fissure sealants (Clinpro and Grandio seal) children were
followed up 56 months later. Due to loss to follow-up, only 21 children with 75 sealents were evaluated for
sealant retention. Each sealant was evaluated in terms of retention using the following criteria: 1 = completely
retained, 2 = partial loss, and 3 = total loss. The Pearson χ2 test was used to evaluate differences in retention
rates among the sealants used with different enamel preparation method.
Results: No statistically significant differences were found between the retention rates for case group and
control group regarding the method and sealent type at 56-month evaluation period (p>0.05).
Conclusion: Although statistical evaluation didn’t show significant difference, but sealant retention was more
evident after preparation technique.

Introduction: Pre-eruptive intracoronal resorption is a lesion often located within the dentin, adjacent to the
dentin-enamel junction, in the occlusal aspect of the crown. As the lesions resemble caries, they are often referred as -pre-eruptive caries-.
Background: The pathogenesis of pre-eruptive intracoronal resorption is unclear, since the developing tooth is
encased in its crypt and is not likely to be infected with cariogenic microorganisms. The purpose of these case
reports is to describe the diagnosis and treatment of permanent molars with pre-eruptive intracoronal resorptions and to elaborate on possible associated clinical problems.
Case Reports: In this case presentation, two pediatric patients (aged 6 )with no contributing medical history
were referred to Kocaeli University’s Faculty of Dentistry Department of Pediatric Dentistry Clinic for routine
clinical examinations. Panoramic radiographies demonstrated unerupted mandibular first molars with a clear
radiolucent area in the crowns extending from the occlusal surface into the dentin. No periapical pathology
had been observed. Clinical examinations revealed the alveolar mucosa of the first molars with normal color,
texture, and contour. Pre-eruptive intracoronal resorptions were diagnosed, and the decision was made to
remove the defective tooth structure in the resorbed areas and restore the teeth. After administration of local
anesthesia, the gingival tissues above the unerupted molars were retracted by 810 nm diode laser, revealing
the occlusal surface of the first molars.An opening to the cavities were made with a high-speed bur and the
caries-like tissues were removed with a low-speed round bur. Then the cavities were lined with a calcium
hydroxide base and the teeth were restored with composite resin.
Conclusion: During the follow-up period, soft-tissue healing progressed normally and the teeth have been asymptomatic. Early diagnosis and treatment of pre-eruptive intracoronal resorption are essential to avoid pulp
involvement after/before tooth eruption.

Aim: The aim of this study is to compare the bonding strengths and microleakages of the fissure sealants having different pit filling content proportions (Bis-GMA(Grandio seal(%70), Control Seal(%55), Fusio(%65),
Compomer(Dyract seal(%65), Giomer (Beauti sealant(%40) and glass ionomer(Fuji Triage(%100) and different chemical structures.
Material and Methods: 60 upper premolars extracted for orthodontic purposes were chosen. Vestibular and
palatinal surfaces of the teeth were used in the bonding stress tests and occlusal surfaces used in the microleakage tests. Test groups were arranged as; Group-1: Grandio Seal, Group-2: Control Seal, Group-3: Fuji Triage,
Group-4: Fusio, Group-5: Beauti sealant, Group-6: Dyract Seal. Prepared samples had been waited at 370C
for 24 hours, subjected 500 times to thermal cycling test between 5C-55C , and soaked in 0.5 % basic fuchsin
dye solution for 24 hours.
Results: The differences between the pit filling contents and chemical structures of the tested fissure sealants
were statistically significant (P<0.05). Furthermore, the pit filling contents and the chemical structures of the
fissure sealants caused significant differences between microleakages and failure types.
Conclusion: Within the limits of this study, the pit filling contents and the chemical structures of the fissure sealants might have significant effects on the bonding strengths, microleakages, and the failure types.

Methods: The study consisted a sample of 5548 patients aged between 5-15 years (2769 boys and 2779 girls)
referred of our clinic between April 2012 - April 2014. Panoramic radiograph of patients were examined for
teeth number abnormalities. All data (age, sex, systemic disease or syndrom) were obtained from patient files.
Results: In 6.2% of patients (345 patients; 156 boys, 189 girls) were observed teeth agenesis. In 5,9% of
patients (327 patients; 147 boys and 180 girls) and 0.3% of patients (18 patients; 9 boys and 9 girls) were
detected hypodontia and oligodontia, respectively. The most common missing teeth were mandibular second
premolar followed by maxillary lateral incisor, and maxillary second premolar. Symetrical missing was common.In 1.2% of patients (69 patients; 52 boys and 17 girls) were observed supernumerary teeth. The most
common supernumerary teeth were mesiodens (31 patients; 24 boys and 7 girls).
Conclusions: Teeth agenesis are common in Ordu/Turkey. Teeth number abnormalities should be evaluated

Aim: The aim of this study was to determine the incidence of cleft lip and/or cleft palate in a population from
The Netherlands.
Methods: The records of a total of 105 (mean age 14.1±1,8 years old) cleft patients treated at ACTA Amsterdam (University of Amsterdam & VU University Amsterdam) were assessed on a retrospective basis. Data
regarding cleft type, sex, side of cleft and race were collected and analyzed.
Results: Cleft lip and palate (49.5%) was most frequently found, followed by cleft palate (30.5%) and cleft
lip with or without alveolus (20%). Cleft lip occurred more frequently in males (71.4%) but there was no
significant difference in gender in both cleft lip and palate and cleft palate (p>0.05). The left side was more
frequently affected in patients who had cleft lip with or without alveolus . Dutch children (74.3%) were affected more than immigrant children.
Conclusions: Cleft lip and palate was the most frequent cleft type and there was no difference in gender but
cleft lip occurred more frequently in males. The left side was more frequently affected who had cleft lip. More
comprehensive surveys should be conducted in order to supply the lack of data on the occurrence and determinants of oral clefts in The Netherlands.

Aim: The aim of this study was to examine the relationship between parents education/income levels, specific dietary intake behaviors, especially consumption of added sugars, and oral health in children.
Methods: 301 children (158 females and 143 males), aged 3-15 years, who attended Istanbul University,
Faculty of Dentistry, Department of Pediatric Dentistry were included in the study. Oral health examination
of the children were performed and the dmft/DMFT scores were recorded. To provide dietary information,
parents and the children together completed a questionnaire including questions on general health, parents
education levels, family income, frequency of consumption of dietary items, oral hygiene practices, and other
potential risk factors for dental caries. Data were analysed NCSS using (Number Cruncher Statistical System)
2007 Statistical Software (Utah, USA).
Results: The mean dmft was 6.05 (SD ± 4.01) for boys and 5.84 (SD ± 3.87) for girls, whereas the DMFT
for boys and girls was 2.83 (SD ± 1.73) and 2.73 (SD ± 2.46), respectively. Children, whose family income
was lower than 1000 TL, had higher dmft scores although these differences were not statistically significant.
Frequency of consumption of carbonhydrate rich foods (rice, pasta etc.) and fruit-based sugared drinks was
statistically significantly positively associated with experience of caries (P=0.001 and P=0.017 respectively).
In children who consumed meat everyday, the dmft scores were statistically significantly lower than the children who consumed once a week (P=0.047). Carbonhydrate rich snacks (cookies, wafer etc.) intake frequency
is associated with high dmft scores (P=0.002).
Conclusion: Sugar rich dietary intake plays a significant role in dental caries especially in primary dentition of
children who comes from low-income families. Specific dietary guidance is needed to reduce the prevalance
of early childhood caries.

Purpose: The management of mutilated primary incisors in early childhood caries is a clinical challenge and
necessitates the use of intraradicular retention. The aim of this study was to compare clinically composite
posts and glass fiber posts used in restoring badly decayed primary incisors.
Methods: This in vivo study was performed on a total of ten children with mean age of 4.2 years; affected by
early childhood caries. In these children, a total of 35 grossly carious primary upper incisors teeth were restored using two techniques of intra-canal retention, 14 teeth were received posts and cores made of composite
resin (Filtek Supreme XT, 3M), and 21 teeth were received a glass fiber post (RelyX Fiber Post, 3M) cemented
with dual cured self-adhesive resin cement (RelyX Unicem, 3M). Patients were recalled at 6 and 12 months to
evaluate the retention and marginal adaptation of the intra-canal retained coronal restoration.
Results: At 6th month follow-up, out of 21 teeth restored with glass fiber posts; 20 teeth (96%) showed M1
grade of marginal adaptation and only 1 tooth (4%) showed M3 grade of marginal adaptation. While in the 14
teeth restored with composite posts, 11 teeth (79%) showed M1 grade and three teeth (21%) showed M3 grade. At 12th month follow-up, 28 restored teeth (80%) were available for evaluation. Out of 17 teeth restored
with glass fiber posts; 15 teeth (88%) showed M1 grade of marginal adaptation and two teeth (12%) showed
M3 grade of marginal adaptation. While in the 11 teeth restored with composite posts, 8 (73%) teeth showed
M1 grade and three teeth (27%) showed M3 grade. None of the restored teeth showed M2 grade of marginal
adaptation.
Conclusion: The use of glass fiber posts and composite strip crowns resulted in good clinical success re-establishing function and restoring esthetics in ECC.

Introduction: The management of high-caries risk patients with poor oral hygiene and severe decayed teeth
offers a great challenge to pediatric dentists. Newly developed fluoride releasing tooth-colored restorative
materials may be a good alternative to restore the extensive caries lesions of these patients.
Background: This case report describes restorative procedures including newly developed fluoride releasing
tooth-colored materials and proper preventive strategies in 2 high-caries risk patients. Case 1: A 12-year-old
boy with carious maxillary anterior incisors referred to the clinic. Incipient caries lesions were detected in the
buccal surfaces of several teeth. Possible etiological factors (diet, oral hygiene, mutans streptococci counts,
saliva secretion rate, buffer capacity, and caries experience) were investigated and recorded. The maxillary
anterior incisors were restored with restorative glass ionomer (EQUIA Fil) and enamel microabrasion (Opalustre) was performed on incipient caries lesions. The casein phoshopeptid amorphous calcium phosphate
(CPP-ACP) paste (Tooth Mousse) was administered to the patient. Case 2: A 12-year-old girl referred to the
clinic due to extensive carious lesions in her anterior and posterior teeth. Clinical examination revealed defective composite restorations in mandibular central incisors, extensive caries in mandibular lateral incisors, occlusal caries in posterior teeth. Etiological factors were investigated and recorded. The teeth were restored with
Giomer (Beautifil) and hydroxyapatite and fluoride based paste (Remin Pro) was administered to the patient.
Conclusion: After 9 and 12 months, all restorations were clinically successful and no secondary caries or
new carious lesion was detected in both patients. Newly developed fluoride releasing tooth-colored restorative materials are effective alternatives to restore carious lesions in high-caries risk patients. Increasing the patient’s awareness, motivation regarding oral hygiene and applying the preventive strategies in
addition to restorative procedures may reduce the caries risk and prolong the lifespan of restoration.

AİM: The aim of this in-vitro study was to investigate validity of International Caries Detection and Assessment System (ICDAS-II), laser flourescence based device (DIAGNOdent pen), Alternating Current İmpedance Spectroscopy Technique (CarieScan PRO) and light-induced fluorescence evaluator (SOPROLIFE) in the
detection and assessment of incipient occlusal caries.
METHODS: Totally 100 permanent molar teeth were selected and evaluated with each caries detection method. Histological validation was the accepted gold standard. The inter and intra-examiner realibility of caries
detection methods were assessed using the Cohen’s Kappa statistic. The caries detection methods were compared by sensitivity, specificity, positive and negative likelihood rations, areas under receiver operating characteristic (AUROC) curves for occlusal caries and with the Spearman’s rank correlation coefficient againts
histology.
RESULTS: The statistical results of the present study showed excellent diagnostic accuracy for occlusal caries. In addition, all detection methods showed good intra-examiner and inter-examiner reproducibility. All
methods were strongly corrolated with histology.
CONCLUSİONS: All tested methods presented similar performance in detecting occlusal caries lesion and good to excellent reproducibility. The children could be prevented to exposure unnecessary x-ray radiography by visual ICDAS-II caries diagnostic method supported by DIAGNOdent pen, Soprolife and CarieScan PRO devices. Soprolife camera and
computerized monitoring system may be more useful device in pediatric dentistry for initial caries detection.

Introduction: Mineral trioxide aggregate (MTA) has been recommended for root-end filling, pulp capping,
apexification of immature teeth with necrotic pulps, repair of root perforations and horizontal root fractures,
pulpotomy and root canal filling in endodontics. Background The major challenge of performing root canal
treatment in an open apexed tooth is to obtain a good apical seal.The purpose of this study was to evaluate
the efficiacy of MTA clinically and radiographically as material used to induce root end closure in nonvital
permanent teeth with immature apices in children.
Case report: 12- year old boy was reffered to pediatric dentistry clinic suffering from a crown fracture caused
by a trauma which happened a few years ago and marked grayish discoloration of his teeth. The radiographic
examination revealed an immature tooth with wide open apex with a radiolucent area in approximating of
apex tooth According to the treatment protocol, the root canals were rinsed with 5% NaOCl; then, calcium
hydroxide paste was placed in the canals for 1 week.In the second visit; consequently, the apical portion of
the canal (4 mm) was filled with MTA. The remaining portion of the root canals was then closed with thermoplastic gutta-percha. Not showing any symptoms in two weeks, walking bleach technique was used and
the teeth was then restored with composite resins.At 6-month follow-up period the clinical and radiographic
appearance of the teeth showed resolution of the periapical lesions.
Conclusion The apical plug with MTA should be a succesful and effecitve treatment alternative for management of teeth with necrotic pulp with immature root development and periapical lesions. The results indicate
that MTA can be used as an apical plug in the teeth with open apices following root canal debridement and
disinfection with calcium hydroxide.

Introduction: A chronic inflammation of untreated traumatized tooth is one of the reasons for an extra-oral
sinus tract of odontogenic origin. It is a case report of an extra-oral sinus tract of dental origin, its diagnosis
and treatment.
Backround: The patient was a 10-year-old female with a complaint of drainage from a extra oral lesion on
the chin. Her parent stated that she had swelling, pain and fewer when they were referred to state hospital. She
received a large amount of antibiotics both orally and parenterally. Patient had a history of dental trauma 2
years ago and root apex development was interrupted.
Case report: Extra-oral examination showed a nontender elevated crusty nodule approximately 0,5 cm in diameter on the chin. Palpation elicited an exudatous discharge from it. İntraorally, tooth #31 had mobility and
horizontal crown fracture in middle third, showed no respond to percussion. The periapical radiograph showed
diffuse radiolucency surrounding apical part of the root. Nonsurgical endodontic therapy was performed.
Calcium hydroxide and triple antibiotic paste (metranidazol, ciprofloxacin and minocycline) used for intracanal medicament for 4 weeks. The apical part of the root canal was obturated with mineral trioxide aggregate
(MTA). A fiber-reinforced post and composite restoration was accomplished for fractured crown. At 6 months
and 1 year follow-up, clinical and radiographic examination showed healthy tissues and tooth.
Conclusion: This report emphasizes the importance of early treatment of traumatized teeth and nonsurgical
endodontic treatment approach to extra-oral fistulas caused by necrotic pulp.

Aim: The aim of this study was to investigate the effect of three intracanal medicament [calcium hydroxide
(Ca[OH]2), double antibiotic paste (DAP) and triple antibiotic pastes (TAP)] placements on the bond strength
of Biodentine and MTA+.
Methods: Forty-eight single-rooted human mandibular premolars were decoronated and the root canals enlarged up to size 140 to simulate immature root apices and randomly divided into a control group (without intracanal medicament) and three experimental groups that received an intracanal medicament, either Ca(OH)2,
DAP (metronidazole, ciprofloxacin) or TAP (metronidazole, ciprofloxacin, minocycline). The intracanal medicament was removed by rinsing with 10 mL 17% EDTA followed by 10 mL of 2.5% NaOCl. Each group was
further equally divided into two sub-groups and the cavities filled with either MTA+ or Biodentine (n=12).
Push-out test was used to measure the bond strength between the root canal dentin and the cement. The data
were analyzed using two-way analysis of variance (ANOVA) and LSD post-hoc tests (P=.05).
Results: A two-way ANOVA revealed that the bond strength was not significantly affected by the intracanal
medicaments or cement type (P>.05). However, there were significant interactions between the intracanal
medicament and cement type (P<.001). There were no significant differences between MTA+ and Biodentine
after the different medicament applications for all multiple comparisons (P>.05). Also, there were no statistically significant differences between the intracanal medicament in the MTA+ group (P>.05). Biodentine after
TAP application resulted in the highest bond strength. In the Biodentine group, there was a significant difference between TAP with DAP (P=.012) and TAP with control group (P= 034).
Conclusions: TAP placement improved the dislodgement resistance of Biodentine. However, the bond
strength of the MTA+ was not affected by the use of intracanal medicament. Antibiotic combinations, especially minocycline, could remain within the dentin and affect the bond strength values of the cement.

Aim: To compare the effect of Mineral Trioxide Aggregate (MTA), Biodentine and Calcium Hydroxide (CH)
on the fracture resistance of immature teeth after apexification.
Materials and methods: The crown and the apical 3 mm part of the 65 single-rooted teeth were removed. The
root canals were shaped with ProTaper files up to F5 size. Simulation of roots into immature apices were
carried out using size 4 green 1.5 mm diameter Unicore drills. The specimens were then randomly divided
into 5 groups (n = 13). In CH and positive control groups, roots were filled CH and soaked in distilled water
for 3 months. The root canals in the CH group were filled with Gutta Percha and AH Plus Sealer. The root
canals in the positive control group were left unfilled. The root canals in the negative control group were left
unprepared. In the other two groups, the root canals were fully filled either with MTA or Biodentine. The most
coronal part was flattened and the roots were simulated with artificial periodontal ligament using 0.2 mm silicone impression material teeth having fixed in acrylic resin molds. All the teeth were fixed in the Universal
Testing Machine and vertical force with 1mm/min crosshead speed was applied until failure occurred. The
values were recorded in Newtons. SPSS 15.0 was used for statistical analysis. One-way ANOVA and Tukey
HSD tests were used for statistical analysis of the groups.
Results: Biodentine group showed the best results followed by CH, MTA and control groups (p<0.05). There
were no significant differences between the groups MTA, CH and negative control groups (p>0.05) and these
groups were found statistically better than positive control group (p<0.05).
Conclusion: This in vitro study showed that Biodentine demonstrated the best results in the fracture resistance
of immature teeth. However, further clinical trials are needed.

Aim:The aim of this study was to evaluate the antibacterial activity of resin modified (RM) and high viscosity
(HV) glass ionomer cements (GIC) containing chlorhexidine (CHX)/cetrimide(CT) mixtures against Streptococcus mutans. The CHX/CT powders were added to the powders of RM and HV GIC at the concentration of
2,5%/2,5% (total of 5%) and selected as experimental groups (EXP:RMEXP and HVEXP). Antibacterial free
groups were prepared as controls (CNT:RMCNT and HVCNT).
Methods:A total of 12 disc shaped specimens (10 mm diameter, 1mm depth) were used of the agar diffusion
test (ADT). The antibacterial activity of EXP and CNT groups were tested at 1,7 and 14 days. Mann Whitney
U test was used for comparing the antibacterial activity of EXP groups (p<0.05).
Results:According to the ADT; no inhibiton zones were obtained at 1, 7 and 14 days period both for RMCNT
and HVCNT. At day 1; no significant differences were found between the RMEXP and HVEXP (p>0.05)
whereas significantly higher antibacterial effects were found in HVEXP compared to the RMEXP (p<0.05) at
7 and 14 days period.
Conclusions:The incorpoartion of CHX/CT mixtures to the RM or HV GIC may provide antibacterial action
against Streptococcus mutans. Adding CHX/CT mixtures to the HV GIC can be considered as an acceptable
combination to inhibit the bacteria particularly for the atruamatic restorative treatment.

Aim : The aim of this in vitro study was to compare the effects of different cavity disinfectants and KTP laser
on microtensile bond strength to primary dentin.
Methods : Twelve primary molar teeth were used in this study. One third of the teeth (from coronal portion)
were removed to obtain flat surfaces. Chlorhexidine (CHX), propolis (PRO), ozonated water (OW), gaseous
ozone (OG) and KTP laser were used for disinfect the cavity. After this application an adhesive (Prime&Bond
NT) was applied to dentin surfaces and composite crowns were built up. One group received no pre-treatment
and was set as control (CONT). Ten sticks were obtained from these samples and were stressed in tension until
failure using a universal testing machine and the data were recorded.
Results : The mean strength values (in MPa) of the sticks were OW(11.12)> KTP(9.58)> CHX(7.58)>
PRO(7.42)> CONT(6.38)> OG(5.84) and OW showed significantly higher results than the other groups, except KTP group (p<0.05).
Conclusion : Within the limits of this study, it could be concluded that OW and KTP laser might be used safely
as cavity disinfectants in primary teeth without compromising the bond strength of restorative materials.

Aim: To investigate the effect of ethanolic extracts of propolis (EEP) added in different proportions to fissure
sealant on shear bond strength (SBS) and microhardness.
Methods: The sealant was divided into six groups: one using the original composition and five with 0.5 %,
0.35 %, 0.21 %, 0.13 % and 0.10 % EEP added to the fissure sealant. A total of 78 freshly extracted non-carious human first molar teeth were randomly divided into six groups of 13 each. The buccal surfaces of all
teeth were polished with 600-grit paper to create standard smooth surfaces. After etching, the fissure sealant
(Fissured Nova; IMICRYL, Konya, Turkey) with different propolis proportions was applied and light cured
with a light-emitting diode (LED) according to the manufacturer’s recommendations. SBS was evaluated in
failure using a knife-edge blade in a universal testing machine with a crosshead speed of 1 mm/min. Disk
shaped specimens were prepared from tested fissure sealants to determine Vickers hardness (VHN). SBS and
microhardness data were analyzed using One Way ANOVA and Tukey HSD tests.
Results: SBS values of 0,5 %, 0,35 % and 0,21 % propolis-containing groups showed failure on bonding. SBS
values of 0,13 % and 0,10 % propolis-containig groups were not statistically significantly different compared
with control group (p>0.05). 0,35 propolis-containing group showed highest microhardness values compared
to other groups (p<0.05). Control, 0,13 % and 0,5 % propolis-containing groups showed similar VHN values
with each other (p>0.05) and higher VHN values than 0,21 % and 0,10 % ones (p<0.05).
Conclusions: The addition of 0,13 % and 0,10 % propolis to fissure sealant did not change SBS. So
that; it can be used safely during routine dental practice due to its antibacterial property. But the proportional relationship was not observed between the amount of EEP in fissure sealant and microhardness.

Aim: To evaluate the effect of photo-activated disinfection (PAD) on shear bond strength (SBS) of flowable
composites to dentin.
Methods: Forty-four teeth were used. Buccal enamel surfaces of the teeth were removed and dentin surfaces
of teeth were polished with 400-grit paper to create standard flat surfaces. The teeth were randomly divided
into four groups (n = 11). In the control groups, Vertise Flow self-adhering flowable composite (Kerr, Orange,
CA, USA) and X-tra base bulk (Voco GmbH, Cuxhaven, Germany) composite were applied to the dentin according to the manufacturer’s instructions. In the PAD groups, PAD solution was applied to the dentin surfaces
according to the manufacturer’s instructions. Then, flowable composites were applied to the dentin surfaces
and polymerized. SBS was evaluated until failure occurred using a knife-edge blade in a universal testing machine. The data were analyzed with One-way analysis of variance (ANOVA) and Tukey HSD test (α = 0.05).
Results: X-tra base showed statistically higher SBS value than did the Vertise Flow (p<0.05). Both PAD
groups showed higher SBS than control groups but this was not statistically significant (p>0.05).
Conclusion: Disinfection of dentin surface with a PAD solution would be favorable in terms of not adversely
affecting the SBS of flowable composites.

Aim: Dental caries is a very common disease that can be arrested in its early stages. Approximately 90% of
carious lesions are found in the pits and fissures of permanent posterior teeth. For the prevention of caries,
pit and fissure sealants are widely used. The aim of our study is to evaluate retention and caries prevention of a glass-ionomer cement (GIC) fissure sealant (Fuji Triage Capsule,GC), a resin-based fissure sealant
(Clinpro,3M ESPE) and a glass-ionomer cement (GIC) based varnish (Clinpro XT Varnish,3M ESPE) placed
on the first permanent molars.
Methods: The study is a pilot, randomized clinical trial. Children with three caries-free permanent first molars
with deep pits and fissures were included in the study. Sealant materials were applied on 108 first permanent
molars in 36 children who were at the age of 7-12. Retention, quality of sealing and caries development were
clinically examined, both tactilely and visually, immediately and after 3 months, 6 months and 1 year.
Results: GIC sealants were completely lost in 19,4% , resin-based sealants in 8,3% and GIC based varnish in
52,7%. The total retention rates of GIC sealants were 33,3%, resin-based sealants were 61,1% and GIC based
varnish was 27,7%, respectively. The caries development was seen in 1 tooth for GIC sealants, in 1 tooth for
resin-based sealants and in 3 teeth for GIC based varnish.
Conclusion: The retention of resin-based sealants was markedly superior to the retention of GIC sealants and GIC based varnish. More accurate results can be achieved by increasing the number of patients.

Aim : The success of the vital pulp therapy could only be achieved by maintaining vitality of pulp cells. To
maintain viability, it is compulsory to use biocompatible, non-cytotoxic materials. The aim of this study was
to evaluate cytotoxic effects of BiodentineTM, Pro-ROOT MTA, FormoCreasol (FC), Ferric Sulphate (FS)
and Calcium Hydroxide (Ca(OH)2) on dental pulp cells of primary teeth.
Material&Method: To evaluate cell viability, the materials and Cell cultures were prepared according to the
manufacturers\’ instructions under aseptic conditions. (L 929) Mouse fibroblasts were used as toxicity targets.
On the 1st, 3rd and 7th day, cytotoxicity of MTA, BiodentineTM, FC, FS, and Ca(OH)2 were analysed with
3- (4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl) -2-(4-sulfophenyl)-2H- tetrazolium (MTS) assay
and the results were statistically evaluated by INSTANT (Graph Pad Inc. USA).
Results : According to MTS results on the 1st, 3rd and 7th days MTA was found the most biocompatible material; Biocompatibility of BiodentineTM, FC, FS and Ca(OH)2 showed statistically no significant difference
(p>0.05) and biocompatibility of MTA and BiodentineTM was found statistically not significant difference
(p>0.05).
Coclusion : BiodentineTM can be considered as an alternative material for Pulp therapy in pediatric patients
because of its low cytotoxicity. It is concluded that more work is required in this field can be recommended.

Aim: Mineral Trioxide Aggregate (MTA) is used widely in endodontic therapy as a pulp-capping material,
root-end filling material and perforation-repair material. Although MTA has many favorable properties, it has
some disadvantages. One of the major disadvantages of the material is its long setting time, which, in turn,
necessitates multiple visits by the patients. Therefore, many attempts were made to improve the clinical manageability of MTA by adding a setting accelerator. The aim of this study was to evaluate the effects of several
additives on setting time.
Methods: ProRoot white MTA (WMTA) (Dentsply, USA) was mixed with various additives which tested
include distilled water, saline, anesthetic solution (2ml articaine HCl + 0,010 mg epinephrine, Maxicaine),
15% disodium hydrogen phosphate (Na2HPO4)(Merck, Darmstadt), K-Y Jelly (Johnson & Johnson, Canada),
5% and 10% calcium chloride (CaCl2)(Merck, Darmstadt). The setting times were evaluated using a Vicat
apparatus (Utest UTCM-0028). The molds used to test the samples were 10 mm wide and 2 mm deep. After a
homogenous mix was achieved, the cement was transferred into the molds. Setting time of the materials was
measured under controlled temperature and humidity (37±1°C and 95±5% relative humidity). The samples
were tested at 5-minute intervals until fully set. The setting time was recorded when the needle failed to create
an indentation in three separate areas.
Results: The setting time of MTA mixed with 10% CaCl2 (27±2,83); K-Y Jelly (30±1,41); 15% Na2HPO4
(32±2,83) and 5% CaCl2 (35±2,83) were shorter than that of MTA mixed with distilled water (140±2,83);
saline (148±4,24); anesthetic solution (163±2,83). Saline and anesthetic solution extended the setting time.
MTA mixed with 10% CaCl2 showed the lowest setting time.
Conclusions: This in vitro study, the various additives could be possible substitutes to water to decrease
MTA setting time. Nevertheless, more study will be needed to improve MTA\’s preexisting advantages.

Aim: The aim of this in-vitro study was to compare the microleakage of self-adhesive flowable composites to
their counterparts applied with three different adhesive systems (3-step etch and rinse, 2-step self-etch, and
1-step self-etch) in Class V cavities.
Methods: Seventy-five standardized Class V cavities were prepared on both buccal and lingual/palatinal surfaces of extracted non-carious human molar teeth. The occlusal margins were located on the enamel where
the gingival margins were extended 1 mm below the cemento-enamel junction. Following preparation, all
specimens were randomly divided into five groups: (1) self-adhesive [Fusio Liquid Dentin (FLD)], (2) self-adhesive [Vertise Flow (VF)], (3) adhesive (3-step etch and rinse) [Gel Etchant/Optibond FL/Clearfil Majesty
Flowable] (3Er/flowC), (4) adhesive (2-step self-etch) [Clearfil SE Bond/Clearfil Majesty Flowable] (2Se/
flowC), (5) adhesive (1-step self-etch) [Clearfil S3 Bond Plus/Clearfil Majesty Flowable] (1Se/flowC). After
thermocycling and immersion in a 0.5% basic fuchsin, the restorations were sectioned and dye penetration
was evaluated under a stereomicroscope (n=30). The data were statistically analyzed with Kruskal-Wallis,
Mann-Whitney U and Wilcoxon Signed Ranks tests (α=0.05).
Results: At the enamel interface, no significant differences were observed between the microleakage scores of
VF, FLD and 3Er/flowC, while they showed significantly lower leakage scores than 2Se/flowC and 1Se/flowC
(p<0.05). At the dentin interface, 3Er/flowC and 2Se/flowC exhibited lower leakage scores than VF, FLD and
1Se/flowC (p<0.05). VF, FLD had higher leakage scores at the gingival margins, while higher scores were
detected at the enamel margins in 2Se/flowC and 1Se/flowC (p<0.05).
Conclusions: Both self-adhesive flowable composites showed similar microleakage scores to the 3-step
etch and rinse adhesive/flowable composite in enamel, whereas their performance in dentin was worse
than 3-step etch and rinse adhesive/flowable composite and 2-step self-etch adhesive/flowable composite.

Aim: To evaluate the effect of different surface pre-treatment methods on the microleakage of self-adhesive
flowable composites (SAFCs) in comparison with a conventional flowable composite applied with an etch-and-rinse adhesive system.
Materials and Methods: A hundred and thirty-five standardized class-V cavities were randomly divided into
nine groups: (1) three-step etch-and-rinse adhesive [Optibond FL, Kerr]/flowable composite [Clearfil Majesty
Flow, Kuraray] (E&Ra/flowC), (2) Fusio Liquid Dentin [Pentron], (3) Er:YAG Laser/Fusio Liquid Dentin
(Er&Las/Fusio Liquid Dentin), (4) Phosphoric Acid/Fusio Liquid Dentin (PhosA/Fusio Liquid Dentin), (5)
Polyacrylic Acid/Fusio Liquid Dentin (PolyA/Fusio Liquid Dentin), (6) Vertise Flow [Kerr], (7) Er:YAG
Laser/Vertise Flow (Er&Las/Vertise Flow), (8) Phosphoric Acid/Vertise Flow (PhosA/Vertise Flow), and (9)
Polyacrylic Acid/Vertise Flow (PolyA/Vertise Flow). After thermocycling and immersion in a 0.5% basic fuchsin, the restorations were evaluated under a stereomicroscope (n = 30). The data were statistically analyzed
(a = 0.05).
Results: Both SAFCs showed higher leakage scores than E&Ra/flowC in enamel and dentin (p < 0.05). Vertise
Flow showed lower leakage than Fusio Liquid Dentin in dentin (p<0.05). Pre-phosphoric acid etching reduced the microleakage scores of Fusio Liquid Dentin in both enamel and dentin (p < 0.05), while all surface
pre-treatment methods led to a significant reduction in the microleakage scores of Vertise Flow at the enamel
margin (p < 0.05).
Conclusion: Pre-etching of enamel and dentin by phosphoric acid may be satisfactory in improving the sealing
ability of Fusio Liquid Dentin, while phosphoric acid or polyacrylic acid etching or laser irradiation may be
used to improve the adhesion of Vertise Flow to enamel.

Aim: The aim of this study is to compare the effect of a universal, a bulk-fill and a flowable composite on the
cell viability of both human pulp stem cells (hPSCs) and periodontal ligament stem cells (hPLSCs) derived
from 3rd molar germ.
Methods: Three different restorative materials, Tetric EvoCeram, Tetric EvoCeram Bulk Fill and Tetric EvoFlow, were tested regarding to cytotoxicity in vitro. Samples of each material were put in Teflon rings (5mm x
2mm) and polymerized using a light unit. Then, samples were placed on transwell inserts (with a pore size 3
μm) where the materials were co-cultured with hPSCs and hPLSCs. The toxicity was evaluated by the MTS
(3-(4,5-dimethyl-thiazol-2-yl)-5-(3-carboxy-methoxy-phenyl)-2-(4-sulfo-phenyl)-2H-tetrazolium) assay on
days 1, 3, 7, 10 and 14. 20% dimethysulfoxide (DMSO) was used as positive control (PC) group and non-treated cells were used as negative control (NC) group. For the statistical analysis GraphPad Prism software
program was used and analysis was made by one way-ANOVA.
Results: The results showed that Tetric EvoCeram, Tetric EvoCeram Bulk Fill exerted no cytotoxicity, but
Tetric EvoFlow caused cytotoxicity (p < 0.05) of almost all of the cells at the day 14th on both cell types.
Conclusion: The study showed the cytotoxicity of dental resin composites recently used in pediatric dentistry.
These results suggest that Tetric EvoCeram and Tetric EvoCeram Bulk Fill can be pereferable than flowable
version for tooth restoration in deep cavities and also the biocompability of restorative materials should be
considered when choosing for the procedure besides other physical properties. This study was supported by a

Objectives: This study investigated the radiopacity values of glass ionomer and resin based bulk-fill restoratives by using digital radiography system. Methods: Two different glass ionomer based (Equia Fil, GCP Glass
Fill), three different resin based (SDR Bulk Fill, Quixfil, Filtek Bulk Fill) bulk-fill restorative materials, and as
a control conventional composite material were used in the study. Three disc-shaped specimens were prepared
from each of these materials, at different thicknesses (1 mm, 2 mm and 4 mm), and tooth slices were obtained
with the same thicknesses. As a control, an aluminum stepwedge varying from 0.5 to 10 mm in thickness was
used. Materials were placed over a CMOS (Complementary Metal Oxide Semiconductor) sensor together with
the tooth slice and the aluminum stepwedge and were then exposed using a dental x-ray unit. The images were
analyzed by means of a software program to measure the mean gray values (MGVs). Five measurements were
obtained from each of the restorative materials, enamel, dentin and the stepwedge. The MGVs were converted
to the equivalent of the aluminum thicknesses. Two-way ANOVA was used to investigate the significance of
the differences among the groups. Tukey’s test was applied for pairwise comparisons (p<0.05).
Results: GCP Glass Fill presented the lowest radiopacity values (1.95±0.035, 3.44±0,070, 6.53±0.076 mm Al
for 1, 2, 4 mm respectively) of all the groups while Quixfil were the highest (5.04±0.10, 8.51±0.11, 14.73±0.13
mm Al for 1, 2, 4 mm respectively). All bulk-fill restoratives were found to be higher than the enamel and dentin except the GCP Glass Fill. The radiopacity rose with the increasing thicknesses of the restorative materials.
Conclusion: All investigated bulk-fill restoratives passed the ISO requirements for radiopacity values.

Aim: The aim of this study was to compare the water sorption and solubility of two different self-adhering
flowable composite resin materials. Methods: Two commercial self adhering flowable composite materials
were selected: i. Vertise Flow (Kerr, Orange, CA, USA) and ii. Fusio Liquid Dentin (Pentron Clinical, Orange,
CA, USA). Twenty disc specimens (6 mm in diameter and 2 mm in depth) were prepared of each material, following the manufacturer’s instructions using an LED light-curing unit at 1200 mW/cm2 (VALO). The samples
were stored in a desiccator for 24 hours at 37°C and then the weight of each sample was measured by sensitive
balance (M1). Following this procedure these specimens were placed in distilled water in an incubator for 24
hours at 37°C. Then the samples were dried with blotting paper. The dry samples were weighed again (M2).
As a finally the samples were stored in a desiccator 24 hours at 37°C and weighed (M3). The same process was
applied to the samples which had been stored in water for 7 days. Results were analyzed using the independent
sample t-test (α=0.05).
Results: Although Vertise Flow water sorption and solubility mean values was higher than Fusio Liquid Dentin, there was no statistically significant difference determined between the tested materials (p > 0.05).
Conclusions: Within the limitations of this study no differences were found between the tested materials with
regards to water sorption and solubility.

Aim: The aim of this study is to measure the effect of thermal cycling on the amount of monomer released
from three different composite materials by HPLC analysis method.
Mehods: Three different composite materials, inlay composite, posterior composite and micro-hybrid composite were used. Sixty cylinder specimens each with a dimension of approximately 1 cm width and 3 mm depth,
were prepared before experiments were carried out. Inlay composite material was polymerized according to
manufacturers instructions. Thermal cycling device was used to simulate thermal differences which occur in
the mouth media. Monomers were analyzed using HPLC technic after thermal cycling process. The amount
of ethoxylated Bis-GMA and urethane dimethacrylate (UDMA) in inlay composite material, the amount of
ethoxylated Bis-GMA in posterior composite material, the amount of ethoxylated Bis-GMA and triethyleneglycol dimethacrylate (TEGDMA) in micro-hybrid composite material were investigated.
Results: Monomer release of thermal cycles levels showed a linear increase in UDMA and TEGDMA
(p<0.05). In terms of thermal cycles levels, Bis-EMA released from posterior composite showed a cubic change (p<0.001). It was observed that use of additional polymerization processes might have positive effect on
the decrease of residual monomer.
Conclusion: In the light of the results, we suggest that indirect composite resins have more outstanding features than direct composite resins in terms of biocompatibility.

Aim: Microorganisms are protected from the negative enviromental conditions by biofilm formed in the
mouth, and they survive for a longer period and proliferate. The usage of anti-plaque agents in pediatric patients causes anxiety and is not preferred due to the toxic effects in these times. Green tea has been reported to
potentially have anti-cancer, anti-oxidant, anti-microbial, and anti-dental caries properties. Aim of this study
, to investigate the usability of the plant materials such as green tea exctract for the prevention of biofilm and
to develop a preparation that can be used in children with space maintainer.
Methods: The study grup were selected for Süleyman Demirel University School of pediatric dentistry clinic
in aged between 6 to 12 years children with space maintainer. Biofilm samples were taken from space maintainer of the body acrylic , acrylic teeth, band - loop space maintainer of metal body and fiber reinforced
compozite space maintainer of body. Mikro-titer plate method were carried out in 96-well culture plates to
determine the biofilm. Exopolysaccharide production was determined by crystal violet. Green tea leaves were
obtained from Rize, Turkey .
Results: S. Anginosus, S. Dysgalatie and S.Mutans was determined at biofilm sample. The greatest concentration of selected isolates of biofilm formation was observed on glucose and sucrose. Compared to other selected
isoletes, Dysgalati to create the most dense biofilm was observed. Black colored colonies of isolates was determined to be positive and orginal yellow colonies did not change colur that was determined to be negative.
The greatest sensitivity microorganisms to green tea have been identified as S.anginosus and S. Dysgalati.
Conclusions: Green tea mouthwash due to its beter taste and no known sideeffects can be used on a daily basis as an alternative agent. It should be explored as a long term anti-biofilm rinse with prophylactic benefits.

Aim: Objective is to assess long-term clinical success and survival rates of glass fiber-reinforced composite
resin (GFRCR) as a space maintainer clinically.
Materials and methods: This study was conducted on 43 children who had premature loss of primary first or
second molars. Space maintainers were prepared on stone models of patients and applied directly to the buccal
surfaces of the abutment teeth with flowable composite. Patients were recalled once every 3 months. Survival
rate, and whether damage to the abutment teeth occurred were evaluated clinically and radiographically, and
prevention of the space was evaluated on stone models for 24 months or until failure. Mann-Whitney U-test
were used for the statistical analyses.
Results: In this study, a total of 55 GFRCR space maintainers were applied to patients aged 6-10 years and 44
of them were controlled regularly. 16,2% of space maintainers were dislodged and determined to be unsuccessful at the end of 12 months. At the 24 month follow-up, 52,2% success was observed with the GFRCR
space maintainer and %31,8 of space maintainers were removed due to permanent tooth eruption. The mean
survival time of space maintainers was determined to be 14.8±3.48 month (min=3, max=24 month). The mean
measure of space among the abutment teeth was measured at 5.89±1.27 mm. No significant relationship was
found between survival time and gender, tooth number, localization and space measure at 6 month intervals
(p>0.05). No caries lesion was observed although the tendency of plaque deposition around the abutment teeth
and it was observed that children and parental satisfaction degree was high.
Conclusion: After 24 months follow-up, addition to aesthetic properties of GFRCR space maintainer, applicability in a single visit and resistance against the forces are determined to be successful. This
situation suggests that, GFRCR space maintainers would be an alternative to metal space maintainers.

Aim: Local anesthetic injection is one of the most fearful and anxious procedure in medical and dental practice
for both children and adults. Because of that reason local anesthetic agent application is a necessary procedure
in modern dentistry and medicine. Warming local anesthetic solution has been advocated by many authors to
reduce pain during injection whereas it has also been reported to have no benefits in reducing pain and accelerating onset of anesthesia.
Methods: A total of 100 volunteer cooperated children were included to this study who underwent dental treatment in Erciyes University Faculty of Dentistry, Department of Pediatric Dentistry. The study design was
created as a basic group which included 100 patients needed bilateral buccal infiltration anesthesia for in the
treatment of bilateral primary first molar. Warmed anesthetic solution (body temperature, BT: 37°C) was injected to one side whereas anesthetic solution at room temperature (RT, 23°C) was injected to the other side.
After the injection, onset of anesthesia was evaluated by probe tactile every 5 seconds. Local anesthetic agent
was warmed to body temperature using CALSET composite heater device (AdDent Inc. USA). All injections
were made by one surgeon in whole patients. A Wong-Baker FACES Pain Rating Scale (FPS) of 0 to 10, which
was designed as 0 being no pain and 10 being the worst pain ever experienced, was given to the patients to
quantify subjective pain during injection process.
Results: Mean onset time of anesthesia was significantly reduced in BT injections than RT injections while
FPS scores during injections for BT injections were significantly lower than RT injections.
Conclusions: According to results of our study, the use of warmed local anesthesia prior to injection would be more beneficial and comfortable, especially in patients who have dental fear.

Aim: The aim of the present study was to compare microtensile bond strengths on composite and compomer
onlay restorations cementated with self-cured and dual-cured resin luting cements using microtensile bond
strength test in mid-dentin section samples.
Methods: For the preparation of the test samples, 10 recently extracted sound primary molar teeth were collected, and placed in 10% formol solution. The teeth were dissected from the occlusal surface to the pulp parallel
to the occlusal surface using a diamond separator in the water. Total of 60 samples were randomly assigned to
4 groups (A1: composite+self cured resin luting cement, A2: composite+dual-cured resin luting cement, B1:
compomer+self-cured resin luting cement, B2: compomer+dual cured resin luting cement). Composite and
compomer material were placed in the molds and each layer was light-cured for 40 seconds. Pre-polymerized
onlay restorations were polymerized with heat and light in Lumamat 100. Rod-shaped samples with a surface
area of 1,00 ± 0.03 mm were obtained from dentin section of the each material above and lateral to the tooth
pulp. The samples were examined under stereomicroscopy at x20 magnification. Microtensile bond strength
on the primary tooth dentin was measured on the extracted primary teeth.
Results: When the study data were compared statistically, there were no significant differences in A1-A2
and B1 and B2 (p>0,05). However, statistically differences were seen in A1-B1 and A2-B2 groups (p<0,01).
Self-cured luting cement groups had shown higher breaking strength. When samples were examined under
streomicroscope, adhesive type fracture was the most prevalent fracture type for the both materials.
Conclusion: It is important that the choice of type of luting cement in onlay restorations. In this in vitro study,
self-cured luting cement were found more higher breaking strength than dual-cured one in mid-dentin section
samples. This in vitro study must be supported with in vivo studies.

Introduction: Dental injuries are often the result of direct trauma. Root fractures involving the permanent
dentition commonly affect the maxillary anterior region. Since the incomplete root development of maxillary
anterior permanent teeth with root fracture is unusual, this case report describes the traumatic injury of immature maxillary anterior left permanent tooth with oblique root fracture.
Background: This case report describes the laterally luxated root fracture with open apices of left maxillary
permanent central tooth. Case report A nine year-old boy with laterally luxated oblique root fracture and without any alveolar fracture of maxillary left permanent central incisor tooth was referred to Karadeniz Technical University, Faculty of Dentistry, Department of Pediatric Dentistry after 1 hour of the trauma. Appropriate
repositioning and splinting of the maxillary left permanent central incisor fracture was achieved for 4 weeks
with orthodontic wire semi-rigid splints and followed-up 15 months. After 15 months of following period, the
maxillary left permanent central incisor was found vital with the apical closure and connective tissue healing
was evident between the fractured root segments.
Conclusion: In conclusion, treatment of root fractures with open apices may provide beneficial healing pattern
with appropriate repositioning, careful splinting and follow-up procedures.

REPORT OF A CASE
Volkan CİFTCİ, Cukurova University Faculty of Dentistry - Department of Paediatric Dentistry,
Cem DOGAN, Cukurova University Faculty of Dentistry - Department of Paediatric Dentistry,
Introduction: Luxation injuries comprise % 15-61 of dental traumas to permanent teeth in childhood. Intrusive
luxation is represented by an axial displacement of the tooth deeper into the alveolar bone. This type of injury
usually involves maxillary teeth and is associated with severe pulpal and periodontal damage. Background:
Treatment and prognosis of traumatically intruded teeth can vary depending on the age of the patient, type of
dentition and the stage of root development. Current management strategies include: passive repositioning,
immediate surgical repositioning and repositioning with dental traction by orthodontic devices, active repositioning.The case report describes the management of traumatically intruded maxillary central incisors.
Case report: A 13-year-old boy was referred to Cukurova University Faculty of Dentistry, Department of Paediatric Dentistry immediately after having fallen. Extraoral examination including TMJ were within normal
limits. Only there were lacerations on the lips and the skin. Intraoral examination revealed the absence of the
central maxillary incisors and mucogingival trauma. After radiographic evaluation, the intrusion of the central
maxillary incisors more than 6 mm into the maxillar bone was realized. In addition a crown fracture was also
detected. In the same session a mucoperiostal flap was elevated and the teeth 11 and 21 were removed by a
forceps via the oral cavity. In order to fix the teeth in their correct position, a non-rigid dental splint was applied to the buccal surface of the teeth for 4 weeks. In the middle of this splint period, the root canal treatments
of the teeth were done. Follow up examination was done after 9 months and the teeth were asymptomatic and
radiographically showed repair of the alveolar bone.
Conclusions: An urgent surgical repositioning is one of the treatment option after severe or moderate intrusion
and a multidisciplinary approach including pediatric dentist and a maxillo facial surgeon is a mandatory.

Introduction: Dental traumatic injuries usually occur in 7- to 12-year-old age group and mostly due to falls and
accidents around the home or school. Anterior region of the mouth is most commonly affected in dental trauma. Dental trauma may affect the teeth and alveolar bone and may involve the pulp and periodontal ligament.
Background: Root fractures in permanent teeth are uncommon injuries, seen mostly in children and show
complex healing patterns. Horizontal root fracture ranges from 0.5-7% in permanent teeth. Mid-root fractures
frequently occur in anterior teeth due to their position in the arch. Types of fractures are transverse to oblique
and single or multiple, complete or incomplete. Diagnosis of incomplete root fracture is time consuming and
complex.
Case Repoert: A 13-year-old male patient was referred to Erciyes University Department of Pediatric Dentistry. The patient has pain in anterior region of maxilla after dental trauma. He had a history of trauma during
a play at the school, 1 hour before he came to our clinic. Clinical and radiological examination showed rood
fracture (coronal third) of the right lateral incisor tooth (#12), complicate crown fracture of the right central
incisor tooth (#11) and crown fracture of the left central incisor tooth (#21). Partial pulpotomy performed to
the right central incisor tooth with MTA under local anesthesia. Crown fracture of left central incisor tooth
restored with composite filling material. Than we applied a semi-rigid splint, especially for the root fracture
for 8 weeks. After 2 months we observed internal resorption of the right lateral incisor and root-canal treatment performed to that tooth, than restored with composite filling material. Splint time extended for 1 month
because of the continuing mobility.
Conclusion: At the 12 months follow-up, all the teeth were asymptomatic, in function, and have not shown any
radiographic or clinical symptoms of pathology.

Tamer TÜZÜNER, Karadeniz Technical University - Pediatric Dentistry,
Introduction: Dentoalveolar traumas occur more frequently in young patients and most affected teeth are
maxillary incisors. Horizontal root fractures in permanent teeth are uncommon injuries among dental traumas,
being only 0.5-7% of the cases. Fractures occur most often in the middle third of a root and rarely at the apical
third. Treatment approach depends on the position of the fracture and extent of root involvement. Background:
A 10-year-old healthy male patient was referred to pediatric dentistry clinic 20 hours later with a history of
dental trauma to the maxillar central incisors due to an accident at school.
Case Report: Extraoral examination showed swelling on the lips with accompanying intraoral hematomas. In
intraoral examination, the tooth #21 was extruded and grade 2 mobility on the coronal segment was evident.
Radiographic examination revealed horizontal fracture in the apical third of tooth #21. The coronal segment
was repositioned and stabilized by splinting to the neighboring teeth with twisto flex and resin composite for
4 weeks. Antibiotics and antiinflamatuary drugs were prescribed. The patient was instructed on oral hygiene
and reccomended to remain on a soft diet. The periapical radiograph shows a radiolucent lesion around the
fracture line on tooth #21 at the 1st month follow-up evaluation. At the 3rd month period, the resorbtion area
was found as similar as the 1st month follow up period. An eighteen months follow-up period, the teeth was
asypmtomatic and showed a positive response to the pulp test.
Conclusion: The dental pulp is characterised by the ability to heal spontaneously in case of early intervention
to root fractures. The vitality of the teeth with horizontal root fracture can be maintained with careful splinting
and follow-up procedures without carrying out any endodontic treatments.

Aim: The aim of this study was to assess prevalence of traumatic dental injuries to children aged 1-15 years
during 2 year period (from April 2012 to April 2014) in Ordu, Turkey.
Methods: A total of 5804 patients have been recorded in Ordu University Faculty of Dentistry Department of
Pediatric Dentistry. Of these, 189 patient’s records were for dental trauma. A total of 284 teeth of 189 dental
traumatized children . ( 71 girls and 118 boys ) were examined. All data (age, sex, systemic disease or syndrom, the period elapsed between trauma, time of seeking dental care, source of trauma, injured primary and
permanent teeth, types of trauma, soft tissue injuries and the treatment procedures) were obtained from patient
files.
Results: The total frequency of trauma in this study was calculated as ( 3.2 % ) during 2 year period. The
males were found to have more traumatic injury than females (p<0.05) . Also, the permanent teeth were more
vulnerable to dental trauma than the primary teeth (p<0.05). The teeth mostly influenced by the traumas were
the upper central incisors in both primary ( 37.5 %) and permanent teeth ( 90.5 %).The main cause of injury
was falls ( 41.7 %).The most common type of trauma in the primary teeth was lateral luxation (32.5 %), while
it was enamel-dentin crown fracture (54.4 %) in the permanent ones. The most common method of treatment
was examination and extracted (40 %) for the primary teeth, and only direct restoration for the permanent teeth
without any endodontic treatment (38.2 %).
Conclusion: The patients, parents and teachers living in Ordu, Turkey should be informed about the dental
trauma and necessity of early treatment of dental traumas

DELAYED REPLANTATION OF AN AVULSED MAXILLARY INCISOR:
A 4 YEARS FOLLOW-UP
Pınar DEMIR, Inonu University - Pediatric Dentistry,
Cıgdem GULER, Ordu University - Pediatric Dentistry,
Esra KIZILCI, Inonu University - Pediatric Dentistry,
Introduction: Avulsion is a type of serious injury which causes damage to dental and supportive tissues. The
most preferable treatment of the avulsed tooth is immediate replantation; however this may not be always
possible. Although replantation of avulsed permanent teeth is the commonly accepted treatment approach, the
long-term prognosis of replanted tooth is still controversial. Prognosis depends on the measures taken immediately at the place of the accident and the length of the time passed after avulsion.
Background: This report describes treatment and the management of an avulsed upper central incisor case
which is diagnosed 3 days after the accident.
Case Report: A healthy 12 year-old boy was referred to the Inonu University, Faculty of Dentistry, Department
of Pediatric Dentistry with a traumatically avulsed maxillary left central incisor, 3 days after the accident. Therefore the extraoral time was 3 days without placement of the the tooth in any storage medium. The patient’s
parents were informed about the possible complications of the delayed replacement and it was preferred to do
the replacement. For the treatment; the tooth was gently replanted, and then it was splinted by using orthodontic wire for 4 weeks. For the ongoing management of the injury; the patient was examined both clinically and
radiographically for 4 years. Replacement resorption was observed and this led to the loss of the tooth after 4
years. After extraction, the tooth was repaired with composite and bonded with a fiber to the other maxillary
incisors and canines.
Conclusions: The replantation has prevented the damage of alveolar bone for 4 years during the childhood
years of the patient. Therefore this study has shown that delayed replantation of an avulsed tooth for a child
should be done even in cases of poor prognosis where the tooth had extended extra-alveolar dry storage.

HORIZONTAL ROOT FRACTURE IN A PRIMARY INCISOR: CONSERVATIVE
MANAGEMENT OF A CASE
Hüseyin KARAYILMAZ, Akdeniz University, Faculty of Dentistry, - Department of Pedodontics,
Hande YALÇIN, Akdeniz University, Faculty of Dentistry, - Department of Pedodontics,
Introduction: Root fractures in the primary dentition are relatively uncommon and establish 1.4-3.8% of all
types of trauma incurred by children in the primary dentition because of the plasticity of the developing alveolar bone. They are most frequent at the age of 3-4 years due to beginning the physiologic root resorption and
weakening of the root.
Background and Case Report: In treatment of root fractures in primary teeth usually, surgical extraction of
the coronal fragment is carried out when root fracture with mobility occurs and apical fragment is leaved for
physiological resorption. Conservative treatment approaches like as repositioning, occlusal adjustment and
splinting are infrequently implemented. Impacted factors of choosing an appropriate treatment include location of the fracture line, the degree of displacement of the tooth and mobility, physiological root resorption at
the time of trauma and cooperation of the child. There is limited publication in the literature about the conservative treatment approaches and prognosis for these cases. The aim of this case report is to present, successful
results of conservative management in a 5 years old boy with horizontal root fracture in a primary maxillary
left central incisor. During one year follow-up, the tooth was clinically symptomless and functional, periodontally healthy, and radiographically, no periapical pathology is revealed.
Conclusion: Conservative treatment maintains functional and esthetic resolution for root fractured teeth,
furthermore prevent emotional problems both for children and their parents due to premature loss of an
anterior teeth. However, supplement studies are needed about conservative treatment approaches for root
fractures in the primary dentition to inhibit the physical and psychological costs of surgical treatments.

Introduction: Calcium hydroxide (CaOH) apexification is the most common treatment for non-vital immature
permanent teeth.The calcific barrier can be complete or incomplete at the apex or a few millimeters short of
it.This report describes the management of 3 non-vital immature permanent teeth with atypical barrier formation at half of the root during CaOH apexification.
Case Reports: Case 1: 8-year-old boy was referred to the clinics of Dept.of Pediatric Dentistry,Istanbul University, with dental trauma after 2 days. Clinical examination showed crown fractures at maxillary right-left
central incisors.Maxillary left central incisor had negative response to thermal pulp test. CaOH was placed as
a temporary root canal filling material;9 months later, radiographic control revealed the bridge formation at
half of the root and root was filled with guta-percha up to barrier.After 2 years follow up, clinical and radiographical examinations showed no symptoms and pathology.
Case 2: 9-year-old boy with swelling at maxillary right incisor was referred to our clinic.Dental anamnesis
exhibited that maxillary right central insicor was restored with composite resin 2 years ago after dental trauma.
CaOH was placed into root canal;6 months later, the radiographic control revealed the bridge formation at half
of the root and the root was filled with guta-percha up to barrier.No clinical and radiographic findings were
seen after 1,5 years follow up.
Case 3: 8-year-old boy was referred to our clinics complaining about swelling with the history of dental trauma occurred 7 months ago.Examinations showed that maxillary left central incisor had a crown fracture and
apical lesion. CaOH was placed into root canal;8 months later the radiographic control exhibited barrier at
half of the root.After removal of atypical barrier, the root was filled with guta-percha. After 3 years follow
up,examinations showed no symptoms and pathology.
Conclusion: Atypical barrier formation during CaOH apexification could also be managed for a good prognosis.

Introduction: Ectopic eruption is defined as the deviation from the normal pattern of eruption leading to a
change in the final position of the tooth. In severe cases, nontreated ectopia may develop into either partial or
complete transposition of lateral and canine teeth. Ectopic eruption of mandibular permanent lateral incisors
can result in premature exfoliation of the deciduous canines or first molars as well as a dental midline shift.
Background: The aim of this case report is to describe the management of ectopically erupted mandibular
lateral incisor by autotransplantation procedure.
Case Report: A 10-year-old girl was referred to our clinics with a chief complaint of a tilting tooth on the right
side of mandible. Clinical examination revealed an alteration of eruption pattern of right lateral incisor, retained primary right lateral and canine teeth, early exfoliation of primary first molar and dental midline shifting
to the right side. Radiographic examination showed that the mandibular right lateral incisor ectopically erupted and was impeding the normal eruption of permanent canine. The treatment plan involved the extraction
of primary lateral and canine teeth followed by the extraction of permanent lateral. The permanent lateral
was stored in sterile saline solution during the preparation of recipient site with implant drill. The donor tooth
was firmly inserted into the recipient site, sutured and splinted to the adjacent tooth with a flexible wire and
composite splint. The splint was used for 4 weeks. The root canal treatment was performed 1 week after the
operation. Clinical and radiological findings during 4 year follow-up period were presented here. At 4-year
follow-up, the tooth was vital, asymptomatic and no radiolucency was observed in radiograph.
Conclusion: Early detection and intervention of ectopic mandibular lateral incisors are important for preventing development of transposition between ectopic lateral incisor and the developing canine germ.

ROOT RESORPTION OF YOUNG PERMANENT INCISOR AFTER ROOT CANAL TREATMENT
WITH TRIPLE ANTIBIOTIC PASTE: A CASE REPORT
Cem DOGAN, Cukurova University - Faculty Of Dentistry,
Buse AYSE SERIN, Cukurova University - Faculty Of Dentistry,
Introduction: The success of the endodontic treatment depends on the microbial suppression in the root canal
and periapical region. In this regard, mechanical instrumentation, irrigation, and intracanal medication are all
important. Triple antibiotic paste containing metronidazole, ciprofloxacin, and minocycline has been reported
to be a successful intracanal medicament in controlling the root canal pathogen and in managing necrotic
young permanent tooth.
Background: The purpose of this case report is to present the treatment of a young permanent tooth with necrotic pulp.
Case report: 15-years-old female patient was referred to our clinic for discoloration and fistula formation in
her maxillary left central incisor. When she was 11 years old, she had a dental trauma and after then orthodontic treatment was performed. Upon clinical and radiographic examination, the pulp of left central incisor
was diagnosed necrotic. Root canal therapy with triple antibiotic paste (metronidazole, ciprofloxacin, and minocycline) was performed at two visits. At 2 months follow-up, root resorbtion was detected by radiographic
examination.
Conclusıon: Necrotic young permanent teeth damaged by caries or trauma can present a challenge to dentistry.
The use of a triple antibiotic paste as an intracanal medicament may provide an alternative to routine treatments however it may be a controversial issue.

Aim: The aim of the present study was to evaluate and compare the effect of acid-etching and Er,Cr:YSGG
laser treatment before the reattachment of incisal fragments in coronal fractures of permanent incisor teeth.
Methods: Sixty-six sound human maxillary incisors were randomly divided into three groups (n=22). Teeth
were embedded in self cure acrylic resins by leaving one third of the crowns out, and uncomplicated crown
fractures were obtained using an Instron testing device. The fragments were reattached by using three different
procedures and a hybrid resin composite (Z250) : Group I: Acid etching + Prime&Bond NT + ; Group II: Er,Cr:YSGG + Prime&Bond NT; Group III: Er,Cr:YSGG + Acid etching + Prime&Bond NT. The percentages of
shear bond strengths were determined by comparing fracture strengths of sound and reattached teeth for three
groups. All data were analyzed statistically with Kruskal Wallis H test.
Results: Mean fracture strengths of the reattached fragments were between 51.02% and 62.93% of the sound
teeth in all groups. Group I had significantly higher percentages of shear bond strength values (p<0.05) when
compared to Group II and Group III. No significant difference (p>0.05) was found be-tween Group II and
Group III.
Conclusions: The findings of the present study show that Er,Cr:YSGG laser irradiation prior to the reattachment of incisal fragments have negative effect on fracture strength.

Introduction: Dental trauma in children and adolescents is a serious dental public health problem.Studies have
shown that some children and adolescents are affected only once with a dental trauma, while others seem to
be accident-prone and suffer from multiple dental trauma episodes.
Background: The present case report describes the management of a paediatric patient suffering from several
episodes of dental traumatic injuries.
Case Report: A 9-year-old boy was referred to Istanbul University,Faculty of Dentistry, Department of Pedodontics; with the chief complaint of pain in maxillary central icisors, along with extra oral swelling.The
patient reported a history of dental trauma following a fall one month ago.Clinical examination revealed that
maxillary central incisors were bulbous with larger mesiodistal diameter and exhibited an anomalous enamel
hyperplasia at the cervical third.Tooth 11,21,31 and 41 also showed patchy areas of white opacities.The parents reported a history of a severe traumatic episode at an age of 3 years, leading to avulsion of 51 and 61,
and luxation of 71 and 81. Both 11 and 21 were tender on percussion and a periapical radiograph exhibited
that the root of 11 and 21 had open apices.These teeth were debrided and medicated with calcium hydroxide
paste.At the 3th month of the dental treatment, the patient experienced a third dental trauma following a basketball accident and both maxillary central incisors sustained crown fracture at the cervical third.At the end of
the apexification procedure,these teeth were restored with fiber post and resin composite.After 1 year of follow-up, the clinical and radiographic findings demonstrated that the adopted clinical protocol was successful
and yielded healthy periodontal tissues with no signs of periradicular pathosis.
Conclusion: Dental injuries result in functional, esthetic and psychological disturbances, accompanied by great concern from the child, the parent and the dentist.This case report implies the importance of conservative
management of multiple dental trauma episodes in paediatric patients.

Introduction: Regenerative endodontic treatment (RET) have been introduced to overcome the limits of the
traditional apexification approach and allow continued root development after treatment of infected immature
permanent teeth. Most RET include the step of intracanal bleeding. In this step care should be employed to
avoid damaging the Hertwig’s epithelial root sheath (HERS). Complete damage of the HERS results in no
further root development. Tooth discoloration is a common finding in RET.
Background: The aim of this case report is to describe one case with severe apical periodontitis and abscess
that were treated by RET using Ca(OH)2 and MTA. Case Report: This report describes the RET of an immature left maxillary central incisor with apical periodontitis and abscess in the patient is 12 yaers old. In the
first treatment visit: The root canal working length was determined. The root canal was irrigated with NaOCl
and saline. The canal was dried with paper points. Ca(OH)2 was delivered to canal system. Access was temporarily restored. After three weeks in the second visit: There was very poor percussion. The Ca(OH)2 was
removed by irrigating with 17% EDTA and with salin. The canal was dried with paper points. Bleeding was
induced. When a blood clot had formed, white MTA was carefully placed on the blood clot. Glass ionomer was
flowed over the MTA and a composite resin restoration was placed over the glass ionomer.
Conclusion: A slow healing process was observed. HERS may be partial damaged. The tooth was asymptomatic
clinically and radiographically during the follow-up period of 2 years. Tooth discoloration was not observed. It is
predicted that apical closure will occur in extended period of time. Calcium hydroxide can be used as an effective
medicament in RET, and successful outcomes can be expected even in severe cases of apical periodontitis or abscess.

Introduction: Vitality of dental pulp is essential for long-term tooth survival. The aim of vital pulp therapy
is to maintain healthy pulp tissue by eliminating bacteria from the dentin-pulp complex. Pulp capping or
pulpotomy procedures rely upon an accurate assessment of the pulp status, and careful management of the
remaining pulp tissue. Partial pulpotomy (Cvek pulpotomy) is the treatment of choice for injured permanent
incisor teeth with exposed vital pulp tissue and immature apices. This treatment preserves pulpal function,
thus allowing continued root development.
Background: The present case report describes cases of four permanent incisors with incomplete root development that performed Cvek pulpotomy, with subsequent apical closure.
Case Report: Four permanent incisors with vital pulps and complicated crown fractures were treated partial
pulpotomy by Cvek technique. This consisted of amputation of 1 to 2 mm of the exposed pulp, placement of
calcium hydroxide. Restorative management included resin restoration and reattachment of the teeth fragments.
Conclusion: Treatments were considered successful in all cases according to the following criteria: absence of
clinical symptoms, absence of X-ray signs of pathology, and presence of pulpal vitality 24 months after treatment.
In conclusion, the Cvek pulpotomy is a successful technique for complicated crown fractures in immature teeth.

A CONTEMPORARY PROSTHETIC AND ORTHODONTIC MANAGEMENT APPROACH OF
TOOTH LOSS AFTER AVULSION: TWO CASE REPORTS
Gülsüm DURUK, Inonu University - Pediatric Dentistry,
Demir PINAR, Inonu University - Pediatric Dentistry,
Introduction: Dental trauma is one of the common and serious problems of children which can cause permanent tooth loss in early childhood years. Maxillar incisors are more affected from trauma, and their loss can
result esthetic and functional problems which can be difficult for treatment.
Background: This report describes treatment and the management of two cases which is diagnosed with tooth
loss, after 3 years the avulsion.
Case reports: Two healthy 11 and 13 year-old patients were applied to the Inonu University, Faculty of Dentistry, Department of Pediatric Dentistry with lost maxillary incisors. The patients had dental trauma 3 years
ago and during the period, both the patients hadn’t have any treatment after the avulsion. Therefore, the teeth
nearby the avulsed teeth, moved to the space and prosthetic rehabilitation was impossible. For this reason,
orthodontic treatment has been performed to achieve a correct redistribution of the mesio-distal spaces with
regard to the median line. After distalization, aesthetic and functional prosthetic rehabilitation have done for
both patients.
Conclusions: In this cases, for the optimum management of the trauma, primarily, we eliminate the complications of the delayed treatment. Therefore, tooth loss may cause severe aesthetic, psychological and functional problems, patients should be rehabilitated prosthetically as soon as possible. In delayed treatments,
elapsed time of trauma damage can causes more complications for the remaining tissues. To prevent this
condition; parents, teachers, pediatricians and even dentists should be informed more about avulsion.

Introduction: Inflammatory external root resorption (IERR) is caused by several etiologic factors including
traumatic dental injury, which may lead to progressive loss of the root structure. When pulp necrosis occurs
following trauma, the necrotic tissue is susceptible to bacterial contamination. The resorption process is maintained by bacterial products from the infected root canal.
Background: Clinically, teeth are usually not symptomatic in the early stage of the process. However, as
IERR progresses, abscess can be seen together with tooth mobility. Radiographically, radiolucencies can be
observed in the external root surface and adjacent to the surrounding bone.The new bioactive materials such
as mineral trioxide aggregate (MTA) can be used in the obturation of the root canal in cases of iatrogenic or
pathologic root resorption.
Case report: A 9 year old male had been referred to Yeditepe University, Faculty of Dentistry, Department of
Pediatric Dentistry with a chief complaint of trauma to permanent maxillary left central incisor. Intraoral examination had revealed enamel-dentin fracture without pulp involvement. Treatment had been carried out by a
resin composite restoration. After 4 years, the patient came with the chief complaint of swelling related with
the treated tooth. Intraoral examination revealed an abscess on the labial mucosa and mobility of the tooth.
Panoramic radiograph showed external resorption on the lateral surface of the root with a poor quality root
canal treatment done by a local dentist. After removal of the root canal filling, the tooth was disinfected with
triple antibiotic paste for 2 weeks. The entire root canal was filled with MTA. Restoration was performed with
composite resin. The patient was scheduled for follow up.
Conclusion: After 6 months follow-up period, there were no clinical or radiographic signs of pathology. Root canal treatment using MTA can be a good treatment choice for external root resorption following traumatic injuries.

Introduction: Discoloration of a permanent incisor tooth in consequence of trauma and inappropriate endodontic treatment may have significant esthetic and social problems on children and adolescents. Background:
The purpose of this case report was to present the multidisciplinary management of a permanent central tooth
which have excessive material loss, severe discoloration and open apex.
Case Report: A 12-year-old female patient was referred to our clinic with a severe discoloration and an extensive tooth fracture. The dental history disclosed that inappropriate endodontic treatment and composite restoration had been performed after her first trauma experience. One year later after the treatment, the restoration
of the tooth was broken. Clinical and radiographic examination revealed that the presence of an unsuccessful
root canal treatment with open apex, complicated crown-root fracture extends below the subgingival area and
severe discoloration. According to the planned treatment procedures, root canal treatment was removed, onestep apexification was performed with MTA (Bioaggregate IBC, Inc) to create an apical barrier and followed
by conventional root canal treatment, intracoronal bleaching was performed (Opalescence Endo, Ultradent).
Then, the root canal obturation was removed to place fiber post (Cytec Blanco, Hahnenkratt) for supporting
the coronal restoration. The fiber post was stabilized into the root canal with dual-cure-luting composite (Variolink N, Ivoclar Vivadent). Following the replacing fiber post, flap surgery was performed to visualize the
palatinal fracture line. After hemorrhage control, the final restoration was made with strip crown. Finally, the
flap was reapproximatted to its original position and sutured. At the end of 6-month follow-up, the clinical
and radiological investigation of the tooth revealed that tooth was asymptomatic, functionally and esthetically
acceptable, had no periapical pathology.
Conclusions: Considering the root development and severe discoloration of a non-vital immature tooth, one-step apexification with MTA and intracoronal bleaching may be seen as a better option.

Introduction: Today, adhesive and composite resin tecnologies allow dentists to restore teeth with different
esthetic problems. Dental trauma and tooth agenesis are common problems of children and adolescents.
Background: This case report decribes estetic and conservative method for the management of missing lateral
incisor with rehabilitation of canine to the shape of lateral incisors and a fractured central incisor with direct
composite restorations which is diagnosed 4 years after the accident.
Case Report: A 14-year-old female patient was referred to the dental clinic of our institution, reporting a dental
trauma of the maxillary left central incisor and esthetic complaints. Dental history revealed that she had a trauma as the result of a fall. The intraoral and radiographic examinations showed that she had a non-complicated
crown fracture, lateral incisor agenesis and canine tooth laterally displaced with diastema. After treatment
plans were offered to the patient it was decided to rehabilite anterior region with composite resins(Amaris,
Voco, Cuxhaven, Germany). The teeth were etched with 37% phosphoric acid, restored with an adhesive
system and a composite. Re-contouring was performed for the diastema on the distal side of 12, mesial side
of the central incisors (11 and 21). Canine was prepared and re-countered with composite resin like a lateral
incisor. Finishing and polishing procedures were performed. She was called for control to evaluate the 1 year
stability of restorations. After 1 years the restorations were found successful according to clinic and radiografic criterias.
Conclusions: Composite resins are effective and offer the advantages of conservative, reversible treatment
directly in the mouth, immediate results and acceptable esthetics. The non-invasive, reversible nature of the
method and the ability to modify make this an attractive procedure.

Introduction: Crown fractures account for the majority of dental traumas.If handled properly, prognosis of
the pulp following a traumatic crown fracture can be favorable.Successful pain management with immediate
restoration of function, esthetics, and phonetics should be the prime objective when handling such cases.
Background: This case report describes the treatment of a right maxillary permanent incisor which had an
uncomplicated crown fracture (UCF) and a left maxillary permanent incisor that had a complicated crown
fracture (CCF) in the same patient and immediate esthetic rehabilitation of the crowns by reattachment of
fractured fragments at the first visit.
Case Report: A 9-year-old medically healthy boy was referred to Istanbul University, Faculty of Dentistry,
Department of Pedodontics, two hours after the dental trauma due to fall.The fractured tooth fragments were
recovered at the site of the injury and stored in water.Clinical and radiographic examinations revealed UCF of
right maxillary central incisor and CCF of left maxillary central incisor.After administration of local anesthesia, indirect pulp capping was applied to right maxillary central incisor with MTA.Left permanent maxillary
incisor with CCF was treated by partial pulpotomy. Partial pulpotomy consisted of pulp tissue removal to a
depth of only 1 to 2 mm, then capping the pulpal wound with MTA.After lining with resin-modified glass-ionomer cements, both central incisors were restorated by reattachment of fractured fragments in the same appointment.Periodic follow-ups are planning to be performed to assess clinically through pulpal sensitivity tests
and radiographically for periapical healing and to evaluate the clinical success of the reattachment procedure.
Conclusions: At the 6-month recall, there was no spontaneous pain; the pulp showed signs of vitality and no periapical radiolucency developed.Reattachment of fractured tooth fragments exhibit a satisfying fuction and esthetics with the use of a very conservative and cost-effective approach.Long-term evaluation is necessary in deciding the success of these treatment techniques.

A CASE REPORT
Sezin AKÇAY ÖZER, Istanbul University - Pediatric Dentistry,
Fatma Zeynep AYTEPE, Istanbul University - Pediatric Dentistry,
Introduction: Dentoalveolar trauma is a very common event in children. Extrusion refers to the vertical partial
displacement of the tooth out of the alveolar bone, resulting from a trauma. The frequency of extrusion have
been found to be %7 among traumatized permanent teeth.
Background : Treatment and prognosis of traumatically extruded teeth can vary depending on multiple factors
such as severity of trauma, age of patient, stage of root development. These teeth may undergo necrosis and
inflammatory resorption and also if untreated extrusion, may cause several problems. The purpose of this case
report is to present a treatment option of a traumatically extruded tooth.
Case Report : A 13-years-old boy with a traumatically extruded maxillary central incisor tooth (#11) was referred to the Department of Pedodontics, Istanbul University in third day after trauma. Orthodontic repositioning
of the tooth was planned in 6 months. At the beginning of orthodontic therapy it was observed that the tooth
was necrotic and needed an endodontic treatment. After orthodontic repositioning, an orthodontic retainer was
applied. After 12 months of follow-up, the tooth was asymptomatic and no pathological sign was observed
radiographically.
Conclusions: Orthodontic applience should be considered as a viable option for managing traumatic extrusion.

Introduction: Pulp exposure due to traumatic injuries in the anterior permanent teeth of children is a common
occurrence. Partial pulpotomy is one of the treatment choice for these injured permanent incisors. This treatment preserves pulpal function, thus allowing continued root development.
Background: The aim of this report was to present the partial pulpotomy with mineral trioxide aggregate
(MTA) and follow-up findings of 2 patients having complicated crown fractures.
Case series: A 9-year-old female patient with a crown fracture of maxillar left central incisor and a 7-year-old
male patient with a crown fracture of maxillar right central incisor were referred to our clinic, 3 and 24 hours
respectively after the trauma. Clinic examinations showed that pulp were exposed but vitality tests were positive. At radiographic examinations, open apices were observed, and no evidence of periradicular pathology
were seen. Teeth were isolated from saliva and the pulp tissue removed to a depth of only 1 to 2 mm. A sterile
cotton pellet moistened with saline was used to apply moderate pressure to the exposed pulp for 5 min. Following achievement of pulp hemostasis, the wounded pulp was covered with MTA (BioAggregate, Innovative
Bioceramix, Vancouver, BC, Canada) and a wet cotton pellet was placed onto the MTA for 24 hours. Final
restorations were performed with composite (Clearfil SE Bond, Kuraray and Clearfil Majesty Esthetic, Kuraray), one day after pulpotomy. At the end of 6 months follow-up, the clinical and radiological investigation
of the teeth revealed that teeth were asymptomatic, vital, functionally and esthetically acceptable, and had no
periapical pathology.
Conclusion: Partial pulpotomy with MTA is an effective treatment option for immature permenant teeth with exposed pulp, in maintaining pulpal vitality and allowing physiological root development.

Introduction: The reported incidence of tooth avulsion ranges from 1% to 11% of all traumatic injuries to the
permanent dentition. The maxillary central incisor is the most frequently avulsed tooth in the permanent dentition. This situation leads to function and aesthetics problems in patients.
Backround: This study was performed to eliminate loss of function and aesthetic considerations in patient with
avulsed anterior tooth because of dental trauma.
Case Report: A 14-year-old ♀ patient was admitted to our clinic because of trauma. As a result of internal
examination of the mouth, it has been seen that tooth #11 has been avulsed; in 21,31,32,42,41 number of teeth
mobility due to trauma were identified and it was decided to make splints. After 2 weeks, in the examination
of teeth #21,31,32,41,42 pulp necrosis was detected.Root canal treatment was applied to the teeth and they
were restored with composite filling material. The gap, that was occured depending on the loss of tooth # 11,
were rehabilitated with ribbond bridge.The oral hygiene education was given to the patient for the treatment
of inflammation which was occured in gingival due to trauma.

Excessive dental protrusion and excessive overjet are characteristics of Class II division 1 cases, particularly
in connection with thumb or lip sucking and tongue thrusting. Class II division 1 malocclusions with a mandibular deficiency have been treated for more than a century with different types of functional appliances.
The principal aims of dentofacial orthopedic treatment of skeletal Class II division 1 malocclusions with
an activator are to correct the dental arch relationship and to improve the patient\’s facial profile by promoting favorable mandibular growth changes. LM-Activator is an orthodontic appliance for early orthodontic
treatment and eruption guidance. This case report describes the treatment of class II division 1 patient with
prefabric LM-ActivatorTM in mixed dentition period. A 10-year-old boy with no general health problems
was referred to the Department of Pediatric Dentistry, Dental School of the Marmara University. The patient had excessive dental protrusion and excessive overjet. LM-ActivatorTM (LM Dental AB, Finland) was
planned to mandibular growth changes. Proper appliance is chosen after some simple measurements at first
appointment. Lateral cephalometric radiograph, intraoral- extraoral photographs, 3Dmd photograph and stone models were obtained at treatment onset and at the end of treatment records. Instructions for use of this
appliance were told patient as 3 hours in day addition to full night usage. Also; patients and parents were
motivated. As a result of Cl ll division 1 patients treatment with LM-ActivatorTM was found effective dentally and skeletally. The outcome of treatment of LM-ActivatorTM has many advantages. The LM-ActivatorTM is simple to use and it requires shorter chair-side time. In addition, the treatment costs will be lowered.

Background/purpose:The aims of this study were to evaluate the clinical and microbiological changes accompanying the inflammatory process of periodontal tissues during treatment with space maintainers (SM).
Materials and Methods: The children were separated into fixed (Group I, n=20) and removable (Group II,
n=20) appliance groups. A full periodontal examination, including probing pocket depth (PPD), bleeding on
probing (BOP), and plaque index (PI), was performed. Anaerobic microorganisms in the crevicular fluid were
detected with culture method. Clinical and microbial evaluations were performed before (T0) and three (T1)
and nine months (T2) after the application of the fixed or removable appliances.
Results: The PI, PPD and BOP scores at the testing sites of both groups increased significantly from before
treatment (T0) to nine months later (T2) (P<0.05), The presence of anaerobic bacteria in the subgingival
dental plaque increased from T0 (n=13, 65%) to T1 (n=16, 80%) in the fixed SM group, but not significantly
(P˃0.05), and the same values were obtained in T1 and T2 (n=16, 80%).
Conclusion: Although, the results of this study demonstrate that the application of fixed or removable SM appliances in children induced an increase of clinical periodontal parameters, anaerobic microbiota consisting of Aa, Pg, and T. forshia were not observed in any of the samples in short term.

Objectives: The purpose of this study was to ascertain the knowledge of parents for dental diseases and their
prevention and to determine the impact of the social status on oral health of children with special needs.
Methods: A semi-structured questionnaire was prepared to collect required information from parents of children with special needs. The questionnaire was completed from parents of two special schools in Kosovo. From
the total of 170 (one hundred and seventy) parents the questionnaire was completed by 104 (one hundred and
four) parents . The average age of parents who completed the questionnaire was 45, from them 65 (62.5%)
were mothers and 39 ( 37,5% ) fathers.
Results: From the surveyed parents (52,9%) of them were with low level of education and a poor living condition, ( 31,7%) of the surveyed parents were with high school level of education and a poor living condition
too with a monthly income of less than 300 euros, (7,7%) of the surveyed were with some level of college
education and a monthly income exceeding 300 euros and (7,7%) surveyed parents were with a higher college
education and with average monthly income exceeding 500 euros. Beside their level of education most of the
parents (86,5%) were thinking that oral hygiene is very important for children’s oral health. Parents of children
with special needs are not sufficiently informed about nutrition and its importance. Majority of the parents
(72,1%) have no information regarding the prophylactic role of fluoride. Most of the parents do not send their
children to the dentist for regular visit, but only when they have pain.
Conclusion: The overall oral health knowledge and attitude of parents of children with special needs is not satisfactory, difficult social-economic situation and lack of information directly affect oral health of their children.

ORAL REHABILITATION OF TWO CASES WITH HYPOHYDRATIC ECTODERMAL
DYSPLASIA
Didem OZDEMIR-OZENEN, Yeditepe University - Pediatric Dentistry,
Hanin FELLAGH, Yeditepe University - Pediatric Dentistry,
Nuket SANDALLI, Yeditepe University - Pediatric Dentistry,
INTRODUCTION: Ectodermal dysplasias (EDs) are known as hereditary disorders that occur as a consequence of disturbances in the ectoderm of the developing embryo ectodermal origin and dysplasia of mesodermally
derived tissues. Patients with ectodermal dysplasia usually exhibit smooth dry skin with partial or complete
absence of sweat glands, defects in the external morphology. Dental manifestations such as hypodontia, peg
shaped teeth, and reduced vertical dimension are also frequently present.
BACKGROUND: EDs have more than 180 different types and 11 subgroups. The most frequently observed
forms of ED are the hidrotic and the X- linked hypohidrotic (anhidrotic) ED type. The X-linked hypohidrotic
type is characterized by the triad of hypotrichosis, hypodontia or anodontia, hypohidrosis and other facial
features.
CASE REPORT: A 10 year-old-boy (Case 1) and an 8 year-old-girl (Case 2) diagnosed with hypohidrotic ED
were referred to Yeditepe University Faculty of Dentistry, Department of Pediatric Dentistry by the Department of Genetics for dental rehabilitation. The patients were siblings whose parents were first degree cousins.
Intraoral examination revealed poor oral hygiene, hypodontia, peg shaped cavitated teeth, and reduced vertical
dimension. Radiographic examination showed hypodontia in the upper jaw and anodontia in the lower jaw.
Case 1 was treated by restoring the carious teeth with resin composite restorations and then an over denture
prosthesis was applied. In case 2, a complete prosthesis was performed. Oral hygiene instructions were given
to the parents, and they have been scheduled for preventive treatments at periodic intervals of three months.
CONCLUSION:These patients have difficulty in everyday life due to some anomalies in their appearance. It is crucial
to refer these patients for psychological help and provide them an appropriate oral rehabilitation for a better life quality.

Aim: Tooth agenesis is the most common congenital developmental anomaly and the first identified genes
have been MSX1 and PAX9. Aims of our study are to search for mutations in MSX1 and PAX9 genes and to
evaluate genetic profile together with missing teeth and other dental anomalies in a patient who has been followed up for 14 years from the age of 4 years and has been treated in our clinic and has a lot of missing teeth.
Methods: Healthy, boy patient who had 13 teeth missing except for third molars and signed the informed consent form was included in this study. DNA was isolated from blood and amplified by PCR. Nucleotide changes
were determined by SNP Genotyping technique. Bidirectional DNA sequence analysis was performed for
mutational analysis of two exons of MSX1 and four exons of PAX9. Results Any nucleotide changes were
not detected in the coding region of MSX1. Two polymorphisms, rs12883298(C>G) and rs12882923(A>G),
were detected in the intron1 region of PAX9. Consequently, no nucleotide changes in association with tooth
agenesis and other dental anomalies in MSX1 and PAX9 genes were observed.
Conclusions: Positive and negative results from genetic studies are important to reveal actual genes causing population-specific tooth agenesis. Screening other candidate genes out of commonly studied genes and searching interactions between genes will provide a better analysis for tooth agenesis models and accompanying dental anomalies.

Background: Pycnodysostosis usually demonstrates typical craniofacial deformities, such as hypoplastic midface, anterior cross-bite, grooved palate and dental crowding. The aim of this case report is to investigate the
responsible genes for pycnodysostosis under reported cases of three siblings with PKND.
Case Report: Three of five siblings (FE 16(♀), ME 10(♀), HE 4(♀)) with PKND applied to our clinic. The
other two siblings (AE 14(♂), ME, twin of ME with PKND, 10(♀)) were PKND-unaffected. All the siblings’
detailed clinical and radiological examination was performed. Taking into consideration the fragility in these
patients, appropriate restorative treatments and protective applications were preferred. Patients were given
oral hygiene education. Recall visits occurred in every 3 months during the 18-month follow-up period. For
mutational analysis, genomic DNA was isolated from buccal cells and seven exons, including exon- intron
boundaries were directly sequenced after amplification. The candidate gene, cathepsin K (CTSK), responsible
for PKND was also analyzed in the affected and unaffected family members.
Conclusions: Early diagnosis and treatment is important with PKND patients, since bone fractures easily occur during dental treatment and limited mouth opening makes it difficult to access the treated area. Frequent
recalls should be planned for PKND patients. Regular oral care and early preventive treatments ensure the
patients a better life quality. Genetically, all the affected members carried L7P variation as homozygous state,
whereas unaffected had the heterozygous state of the same condition. Conclusively, we suggest that L7P mutation may be a diagnostic criteria for this anomaly.

INTRODUCTION: Pierre Robin Syndrome (Pierre Robin Sequence) is a congenital craniofacial anomaly
comprising mandibular hypoplasia, with or without cleft palate, glossoptosis leading to life-threatening obstructive apnea and feeding difficulties during the neonatal period. It is stated that the incidence of Pierre Robin
sequence is estimated to be 1:8,500-14,000. Its inheritance is autosomal recessive also an X-linked form and
associated with trisomy 18 and other syndromes.
BACKGROUND: Cardiac, respiratory, oral and gastrointestinal problems can be seen with this syndrome.
These are cor pulmonale, upper airway obstruction, neonatal respiratory distress, middle ear pathology, glossoptosis, micrognathia, cleft palate,dental crowding and neonatal feeding problems.
CASE REPORTS: First patient is a 12 year old girl. She had surgery when she was age of 1.5 for palatal cleft.
Her extraoral examination shows that she has small mandible and bird-like face. Her intraoral examination
shows that she has dental caries and dental crowding especially in the mandible. Second patient is a 12 years
old boy. When he was born he had surgery for replacement of mandible to prevent glossoptosis. His extraoral
examination shows surgery scars on his angulus of mandible and his mandible is small. His intraoral examination shows that he has dental caries and dental crowding. Both patients- hand and wrist radiograph shows
that, their chronoligical ages are compatible with their bone age. Skeletal Class II anomaly is seen according
to the lateral cephalometric radiographs of the patients.
CONCLUSION: Pierre-Robin Syndrome is realized at very early ages and at birth. This syndrome affects different body systems, so multidisciplinary treatment team should follow-up these patients. Orthodontists and
pediatric dentists are duty to their dental treatment requirements. Aim of these treatments are both increasing
patient comfort and preventing dental anomalies.

Introduction: Epidermolysis bullosa (EB) is an inherited disorder characterized by blister formation following
minor trauma. It is a chronic mechanobullos disease caused by the production of autoantibodies directed against type VII collagen. The disease is associated with conspicuous clinical and oral manifestations. The oral
involvement of EB includes generalized enamel hypoplasia, dental caries, dental morbidity, limited mouth
opening, ankyloglossia, microstomia and tongue erosion. Amelogenesis imperfecta (AI) is a hereditary disorder with dental enamel defects and enamel hypoplasia both in deciduous and permanent dentition. There are
a few case reports in the literature, which indicate the presence of EB along with AI. The aim of this report is
to present the clinical and radiographic manifestations and dental management of EB in a child patient with
hypocalcified form of AI.
Background and Case Report: A 12-year old male patient with EB referred to the Akdeniz University, Faculty
of Dentistry, Department of Pediatric Dentistry with the complaint of pain depends on dental caries and discolored anterior teeth. In accordance with EB, his medical history revealed presence of multiple dermal lesions,
which started to appear immediately after birth. Poor oral hygiene, rampant caries, and generalized gingival
inflammation were seen at intraoral examination. Enamel affected by AI was easily abraded, leaving an irregular surface. As a result of clinical and radiologic evaluation, patient was diagnosed with hypocalcified type
of AI along with EB. Patient’s pulpal and restorative treatments are in progress at our clinic.
Conclusion: An increased risk of caries is the main dental problem for patients with EB. Prevention of dental caries
and periodontal disease must be emphasized at an early age, because of severe limitations and complications of providing dental treatment to patients with EB. Management of patients with EB requires a multidisciplinary approach.

Aim: The aim of this study was to investigate carbonic anhydrase (CA) 6 one single nucleotide polymorphism
(SNP) and its possible association with dental-oral health parameters in children.
Methods: The study population consisted of 178 healthy children (boys and girls, aged 6-15). Caries status was
measured by using the dmft/DMFT (number of decayed, missing, and filled teeth) index. Unstimulated whole
saliva and blood samples were taken. SNP of (CA) 6 gene were determined by PCR and DNA sequencing.
SNPs were detected ; their pubmed database number are rs2274330 (A/G). Salivary pH was measured with pH
paper and salivary flow rate was calculated. Furthermore, the oral hygiene and gingival status were assessed
using the simplified oral hygiene index and gingival index, respectively. Data were analyzed with SAS V9.2.
Results: One SNP (dbSNP: rs2274330 ) which are responsible for amino acid changes, were found. The frequencies of this SNP were not significantly different between the caries-free group and the group with caries. The
frequencies of SNP was not significant between groups (P > 0.05). There was no association between this SNP
and dental-oral health status (OHI and GI) (P > 0.05).
Conclusions: This SNP found have no association with caries in children.

Background: The purpose of this paper was to report three cases of Seckel sydrome with a combination of
clinical and radiographic features.
Case Report: A 6 and 9 year-old male and 10 year-old female patient referred to Istanbul University, Faculty
of Dentistry Department of Pedodontics with a diagnosis of Seckel syndrome. Extraoral examination revealed
growth retardation, microcephaly, micrognathia, bird-like face, speech disorder and inability to walk. Microdontia, congenitally missing teeth, discoloration of anterior teeth, gingival inflammation, enamel hypoplasia,
missing and unerupted teeth was observed according to intraoral and radiologic examination. Oral hygiene
instructions were given. Preventive treatment modalities were explained to parents to prevent possible caries
in future. Recall visits at every 3 months were emphasized.
Conclusion: Seckel syndrome is not encountered routinely in dental clinics, these cases illustrates the importance of dental care in such a rare condition. Regular follow-up provides early intervention and preventive
treatment to avoid unnecessary pain and complications.

Introduction: Goldenhar syndrome (GS) is a rare congenital defect characterized by a combination of anomalies of the face (hemifacial microsomia, unilateral facial hypoplasia, and lateral facial cleft), eyes (epibulbar
dermoid or lipodermoid, colobomas of the upper eyelid, iris, choroidea, and retina), ears (microtia, anotia, preauricular skin tags or blind fistulas, and other external ear malformations), and intra oral (lower jaw, midline
deviation to the affected side, protrusion of the upper incisors, congenitally missing teeth, delayed eruption).
The purpose of this case series was to report six cases of Goldenhar Syndrome with details of craniofacial and
dental findings.
Case reports: The study presents clinical data on the morphologic features, hearing, ophthalmologic, orthopaedic, neurological, cardiovascular, mental and dental findings of 6 Turkish patients (3 male-3 female) aged 4 to
12 years with the clinical diagnosis of GS. All patients have facial asymmetry, sensorineural hearing loss, hemifacial microsomia, mandibular hypoplasia, malformation of the ears, ocular anomalies, obstruction in eyes
duct. Four patients have auricular appendages and pretragal fistulas on the right ear. Two patients are presented
with right external ear agenesia. Two patients were mental retarded. Four patients were born of nonconsanguineous marriage. A 4-year-old girl is reported epipulbar dermoid in the right eye. A 6-year-old girl was born
as a monozygotic twin with heart disease and her sibling without any clinical signs of congenital abnormality.
Fusion tooth was seen in primary canine of 5-year-old girl. The development of dentition and shape of erupted
teeth were in normal limits in all patients.
Conclusions: In this syndrome, multiple-organ involvement can limit the surgical correction of the deformities
and management. Long term and regular follow-up is important to monitor the visual growth and development
of the patient. Ideally, a multidisciplinary team approach is required to manage the other associated anomalies.

Introduction: Dentin dysplasia type 1 (radicular dentin dysplasia) is a rare hereditary disturbance affecting
both primary and permanent dentition which is characterized by defective dentin development with clinically
normal appearing crowns, severe hypermobility of teeth and spontaneous dental abscesses or cysts. Radiographic analysis mostly shows shortened or absent roots, periapical radiolucencies and pulp chamber obliterations.
Case Report: A 15 year-old-boy was referred to Istanbul University, Faculty of Dentistry, Department of Pediatric Dentistry with a chief complaint of dental caries. His teeth had clinically normal crown morphology and
color. Radiographic examination showed short roots with periodontal defects. Intraoral examination of his 36
year-old mother revealed similar condition with short, blunted roots and early loss of multiple teeth. We also
examined his 4 year-old sister, but we didn’t observe any finding of this condition.
Conclusions : A high standard of oral hygiene and maintenance of periodontal health is vital for the survival of affected teeth. Early diagnosis and long-term follow-up of this disease is important to prevent or delay loss of dentition.

Inroduction: Kabuki syndrome (KS) is a rare autosomal dominant disorder of that was first described in 1981
by Niikawa et al. and then Kuroki et al. KS is characterized by a dysmorphic face, postnatal growth retardation, mild to moderate mental deficiency, and craniofacial, skeletal and dermatoglyphic abnormalities with
persistence of fetal fingertip pads. Common characteristic oro-dental features of KS are, cleft lip-palate or the
high arched palate, malocclusion, micrognathia, maxillary recession, hypodontia, microdontia, widely spaced
teeth, fistulae in the lower lips, screwdriver shaped incisors and ectopic upper molars. The aim of this study is
to describe the cranio-facial and dental manifestations, diagnosis and management of ten Turkish patient with
this rare genetic disorder.
Background: A total of 10 KS individuals were referred to our clinic by the Akdeniz University, Faculty of
Medicine Department of Pediatric Genetics, for detailed dental examination with different dental problems.
All of the patients were examined by extra and intra-orally and a large part of the patients were evaluated by
radiograpically.
Case reports: The age of KS patients ranged from 2 to 18 years (4 male and 6 female), with an average age of
8.00 ± 5.77. In the large part of the patients were found to be typical facial appearance of KS. Long palpebral
fissures and sparse arched eyebrows were seen in seven patients. Deep dental caries, high plate, narrow dental
arches and malocclusion were seen at some of the patients in intraoral examination. Radiographic analysis
revealed hypodontia, large pulp chambers of molar teeth and skeletal open bite.
Conclusion: Dental management of the patient with KS should be as a multidisciplinary way. Oral hygiene
education should be given for dental care to patients and their parents. Application of conservative and preventive dental treatment as soon as possible is crucial for these patients.

Elif Bahar TUNA İNCE, Istanbul University Faculty of Dentistry - Department of Pedodontics,
Introduction: Peripheral Ossifying Fibroma (POF) is a non-neoplastic enlargement of the gingiva that is a
reactive gingival overgrowth occurring frequently in the anterior maxilla in teenagers and young adults. The
pathogenesis of this lesion is uncertain and it is thought to arise from periosteal and periodontal membrane.
It is usually related to trauma or local irritants, such as subgingival plaque and calculus, dental appliances,
and/or poor-quality dental restorations. Clinically, POFs are sessile or pedunculated, typically ulcerated and
erythematous or exhibit a color similar to the surrounding gingiva. Most lesions are <2 cm in size, although
larger ones often occur.
Case Report: A 12-year-old girl referred to Pediatric Dentistry Clinics of Istanbul University Faculty of Dentistry with the chief complaint of a soft tissue mass in the anterior maxilla palatal region. The patient did not
give any history of trauma, injury, or food impaction and there was no significant medical history. The lesion
was asymptomatic, non-ulcerated and overlying mucosa appeared normal. No radiological signs of involvement of alveolar ridge were observed. Under local anesthesia, the lesion was completely excised by conventional scalpel surgery. The tissue was submitted to the oral pathology division for histopathologic diagnosis.
After the 15-day follow-up, the surgical site showed uneventful healing. There was no evidence of recurrence
of the lesion after 24 months.
Conclusion: The occurrence of the POFs in children can exhibit an exuberant rate of growth and reach
important size in a relatively short period of time. If surgical intervention in an early stage is not done,
POF can become massive, causing extensive destruction of adjacent bone and significant functional or esthetic alterations. Early surgical treatment of the POF in children including removal of etiological factors is required to obtain satisfactory gingival repair and to attenuate the possibility of recurrence.

Introduction: Unlike other abnormalities which affect a vast number of teeth, Turner\’s hypoplasia usually
affects only one tooth in the mouth and it is referred to as a Turner\’s tooth.
Background: Turner\’s hypoplasia usually manifests as a developmental defect of the permanent successor
tooth, range from mild alteration in enamel mineralization in form of simple white or yellow brown discoloration to severe defective formation of enamel with loss of a portion of missing or severe pitting and irregularity
of tooth crown. If Turner\’s hypoplasia is found on a canine or a premolar, the most likely cause is an infection
that was present when the primary tooth was still in the oral cavity.
Case Report: A 7-year-old boy was referred to our clinic with extensive caries on primary molar teeth. In
clinical and radiographic examination, crown destruction and a large periapical lesion associated with the
permanent tooth germ was observed in the mandibular right primary molar tooth. Also in the radiography, a
developmental anomaly was observed at the permanent tooth. The infected primary tooth was extracted. Since
there was no complaint of the patient, it has been decided to follow-up until the eruption of the permanent tooth. At the follow-up appointments, it was observed that tooth eruption process and root development continued
with a positive response to the pulp test. After 22 months, the conservative treatment of the tooth is completed
with composite restoration.
Conclusion: At the end of 22 months the tooth was clinically and radiographically asymptomatic.

Health Department,
Abstract Introduction: Supernumerary teeth are of particular interest to pediatric dentists, since most commonly they are the ones who make the initial diagnosis. The prevalence of supernumerary teeth is reported
to be from 1 to 3%. It is frequent enough that some recommend an anterior occlusal film as part of a child’s
complete initial examination.
Background: The majority of supernumerary teeth is related to permanent dentition and occurs most commonly in the maxillary anterior region. When occurring in the midline area such tooth is referred to as mesiodens.
Uncommonly, supernumerary teeth might be fused to normal teeth within the arch, most frequently by lateral
fusion. Several problems are related to this type of fusion such as poor esthetics, periodontal problems, crowding and difficulty managing the tooth fused to the supernumerary.
Case report: The aim of the present article is to report the management of two uncommon cases of fused supernumerary teeth both in the maxillary anterior region. First case documents a treatment approach to solve
the esthetic and functional problems of a patient with amesiodensfused to the upper central incisor, considering this patient had limited time and financial constraints for a comprehensive management of the case. The
second case report presents the surgical separation and orthodontic treatment of a maxillary central incisor
fused to a mesiodens.
Conclusion: The technique described here is a simple and effective method for managing supernumerary teeth fused to maxillary incisors in order to restore proper alignment, function and esthetics.

Introduction: Dentigerous cyst, the second most common odontogenic cyst after radicular cyst, could cause
primary teeth retention, delayed tooth eruption, impaction of permanent teeth and its treatment ranges from
marsupialization to enucleation. Background: The objective of this case report is to present the management
of impacted central and lateral incisors due to dentigerous cyst.
Case Report: An 11-year-old boy was referred to the Pediatric Dentistry Clinics of Istanbul University with
the main complaint of retained deciduous incisors on the left upper jaw. Cone beam CT investigation showed
a unilocular radiolucency associated with the crown of the unerupted upper left incisors. Upper left central
incisor had a dilacerated root. Based on the clinical and radiological findings, a provisional diagnosis of dentigerous cyst was further confirmed by histopathologic examination. The treatment consisted of the extraction
of the upper left primary incisors and marsupialization of the lesion. After 7 months of follow-up, the cystic
lesion healed and spontaneous eruptions of the impacted incisors were noticed. The patient was referred for
further orthodontic treatment, after complete eruption of the teeth by 2 years,
Conclusion: Conservative treatment approaches for dentigerous cyst cases should be preferred as the first
treatment choice in chidren based on the facts that destructed bone has greater capacity to regenerate and the
teeth with open apices have greater eruptive potential.

Sayed H. SENIOUR, Facuty of Dentistry, Cairo University - Department of Dental Biomaterials,
Purpose: The management of mutilated primary incisors in early childhood caries is a clinical challenge and
necessitates the use of intraradicular retention. The aim of this study was to compare the tensile bond strength of four different intracanal posts techniques used in restoring badly decayed primary incisors: composite
posts; orthodontic omega “Ω” wire posts; and glass fiber posts cemented with two types of cement.
Methods: This in vitro study was performed on 52 extracted human primary maxillary incisors. Samples were
randomly divided into four groups of 13 each. Group I received posts and cores made of composite resin
(Filtek™ Supreme XT, 3M), group II used posts made from a 0.6 mm orthodontic wire bent as a Greek letter
(omega) “Ω” cemented with (Filtek™ Supreme Flowable, 3M) composite resin, group III received a glass
fiber post (RelyX™ Fiber Post, 3M) cemented with flowable composite, and group IV used the same glass
fiber posts but cemented with dual cured self-adhesive resin cement (RelyX™ Unicem, 3M). The Mounted
specimens were subjected for tensile bond strength on a universal testing machine. The failure values and
modes of failure were statistically analyzed.
Results: Mean tensile bond strength for glass fiber posts cemented with RelyX™ Unicem was (17.0±6.6 kgF),
followed by (16.2±8.5) and (16.1±7.3 kgF) for orthodontic wire posts and composite posts, respectively. The
lowest value (14.5±3.6 KgF) was recorded in group III where glass fiber posts cemented with flowable composite. Statistical analysis (ANOVA) revealed no statistically significant difference between the groups. None
of the samples in group IV showed adhesive bond failure mode.
Conclusion: There was no significant statistical difference in tensile bond strength between the four techniques used; however glass fiber posts when cemented with RelyX™ Unicem showed the greatest dislodging strength, followed by orthodontic omega wire posts and, least of all, composite posts.

EARLY MANAGMENT OF SPACING BETWEEN UPPER ANTERIOR TEETH IN YOUNG
ADULT PATIENTS
Mohamed S. FARAG, Faculty of Dentistry, Suez Canal University - Department of Pedodontics,
Aim: Managing patients with congenitally missing maxillary anterior teeth raises several important issues
concerning the amount of space, the patient’s age, the type of malocclusion, and the condition of the adjacent
teeth. We aimed in this study with early orthodontic intervention to eliminate a lot of psychological problems
that may arise in young adult patients with spacing between upper anterior teeth and to create as well as to
maintain a space for insertion an implant after facial growth had been completed.
Method: 18 patients with spaced anterior teeth were included in this study .The required space for implant
was gained either immediately by creating a space in the same place of the future implant or by moving the
canine first to the place of the future implant and then moving it to create a space for the future implant. Then
this space was maintained by a removable partial denture till facial growth had been completed followed by
implant insertion and crown construction.
Result: The results of this study showed that early orthodontic intervention with closing spaces found between maxillary anterior teeth with the aid of a removable partial denture till facial growth had been completed
followed by implant insertion and crown construction, satisfied all patients psychologically and esthetically.
Conclusion: It was also concluded that stability and success of the implant depends greatly on the facio-palatal width. It was found that moving a tooth to the place of the future implant and then moving it
to create a space for the future implant provided a very sufficient facio-palatal width to insert implant successfully with minimum effort .This technique was much better than insertion an implant with the aid of
bone graft in a space gained orthodontically by creating a space in the same place of the future implant .

Introduction: Autotransplantation is defined as the transplantation of embedded, impacted or erupted teeth
from one site to another in the same individual, into either extraction sites or surgically prepared sockets.
Intentional replantation which is considered as a form of autotransplantation is a procedure consisting of the
extraction of the related tooth, socket preparation if needed and replantation of the tooth to the same site.
Background: A 12-year-old boy was referred to the Department of Pediatric Dentistry, Istanbul University
with a complaint of spontaneous pain in his decayed upper left primary second molar. Panoramic radiography
and computed tomography images showed that upper left second premolar was fully impacted and horizontally positioned in the palate around the apex of the decayed primary second molar.
Case Report: Impacted premolar was planned to be replanted into its original site by surgically. Following
anesthesia of surgical site, the primary tooth and the underlying impacted premolar were extracted. Extracted
premolar was stored in saline while preparing the extraction socket with an implant drill. Once the tooth was
replaced in its final position, occlusion is checked and the replanted tooth was splinted to the adjacent teeth
with resin and wire. Radiological and clinical examination at 3 years follow-up showed that the replanted tooth was asymptomatic, maintained pulp vitality and was still properly functioning.
Conclusion: In young patients, intentional replantation should be considered as a first option in management of an impacted permanent tooth which has a great value for maintaining the balanced occlusion.

Introduction: The restoration of teeth with extensive structural damage is an important clinical procedure in
dental practice. Having untreated anterior teeth had directly been related to the emotional state of children and
their appearance. Treatment of these cases is often complex, time consuming, expensive and unpredictable.
Despite the availability of a variety of materials and techniques, the criteria for selection of such teeth for
restoration may be difficult.
Background: This report decribes, prosthodontic rehabilitation of severely decayed maxillary and mandibulary incisors with BruxZir CAD/CAM milled all zirconia restorations with no porcelain overlay after endodontic treatment, placement of some retentive features and gingival reconstruction with laser surgery.
Case report: A 12 year old male patient with severely decayed anterior maxillary and mandibulary incisors was
admitted to Pediatric Dentistry Clinic of Kocaeli University Faculty of Dentistry. The patient had no systemic
disease or certain deficiency. Clinical and radiological evaluations showed that all maxillary and mandibulary
incisors required endodontic treatment. After periodontal surgery with laser, endodontic treatments were performed. Glass fiber reinforced posts were placed in the canals because of inadequate remaining tooth structure
for restoration. For prosthodontic rehabilitation, all teeth were prepared and restored with BruxZir CAD/CAM
milled all zirconia restorations with no porcelain overlay to provide good esthetic. Examinations after treatment revealed good periodontal health, esthetics and normal function.
Conclusion: The approach to severely compromised teeth should be based on consistent scientific evidence to
reduce failure and improve the prognosis. If restoration is indicated, it must conserve and protect the remaining tooth structure.

Aim: The aim of this study was to demonstrate the presence of H.pylori in the dental plaque and saliva which
are proposed as reservoir for gastric H.pylori of dyspeptic and healthy children respectively and to evaluate
the association of oral colonization of this bacteria with gastric infection.
Methods: Seventy patients with dyspeptic complaints, aged between 5-16 years who have undergone upper
gastrointestinal system endoscopy formed the study group. Control group included thirty healthy children in
the same age group. Oral clinical examination and collection of saliva (2 ml) and supragingival dental plaque
samples were performed. H.pylori was detected in dental plaque and saliva through a real-time PCR system.
Results: Among 70 children who underwent endoscopy 12 were gastric H.pylori (-) and 58 were gastric H.pylori (+) histopatologically. The real-time PCR identified H.pylori in the dental plaque samples of 8 (66.7%)
among 12 gastric H.pylori (-) children, 45 (77.6%) among 58 gastric H.pylori (+) children and 5 (16.7%)
among 30 control group. The real-time PCR also identified H.pylori in the saliva samples of 9 (75%) among
12 gastric H.pylori (-) children, 44 (75.9%) among 58 gastric H.pylori (+) children and 12 (40%) among 30
control group
Conclusion: In both dental plaque and saliva specimens the detection rate of H. Pylori in dyspeptic
group was higher than control group. In gastric (+) and (-) group the detection rates of H.pylori in dental
plaque and saliva samples were similar. Our results indicate that the presence of H.pylori in the oral cavity is not associated with the gastric infection. H.pylori can occur in the oral cavity aside and independently from the stomach. High rates of H.pylori identified in the dental plaque and saliva specimens indicate that the oral cavity is a source of bacterium for the transmission of infection by the oral route.

Aim: Dual-beam platform allow the use of FIB as a nano-scalpel to reveal site-specific subsurface microstructures which can be examined in great detail by SEM. The purpose of this study was to observe, the sound
enamel with a FIB/SEM. Material method: FIB/SEM tomography studies were performed using -slice and
view- technique at the JEOL JIB 4601F MultiBeam platform. FIB milling was carried out on the sample at the
conventional angle of 53° such that the ion beam impacted perpendicular to the sample surface and was able
to sequentially -slice- surfaces away from the volume of interest, while electron beam was used to image the
cross-sectional surfaces simultaneously. Prior to milling, a protective Pt layer 1-2 μm thick was deposited on
the top surface of the region of interest. Ion currents for the milling processes varied from 0.3- 3 nA for bulk
removal to 10-50 pA for milling of slice and view layers, depending on the observed levels of milling artefacts
or redeposition of material.
Results: The sound enamel surface with magnifications of 5000x, 10000x, 15000x, 20000x, 30000x was imaged by SEM and the cross-sections of subsurface with magnification of 4500x, 5000x, 12000x, 30000x were
imaged using FIB. The subsurface profiles of healthy surfaces obtained using FIB have shown no subsurface
cracking.
Conclusion: Detailed morphological analysis is critical to understanding the structural features of enamel and
designing preventive strategies. We also aim to continue this work to see the subsurface of demineralized and
remineralized enamel by using FIB/SEM technology

Aim: The purpose of this study was to determine the total atomic cross sections, effective atomic numbers and
electron densities of the human teeth at different photon energies of 22.1, 25, 59.5 and 88 keV using a narrow
beam transmission method.
Methods: The tooth samples for which different types of treatments such as Er:YAG laser irradiation and 37%
orthophosporic acid solution were applied were compared with the control group if any change exists with
respect to the photon interaction parameters. Finally, the obtained results were compared with the theoretical
values calculated based on the WinXCom database.
Results: With respect to the different groups considered as subjects, it should be mentioned that the percent
deviation value of the effective atomic numbers ( ) for the laser applied group as compared to control group
ranges between 0.5% to 1.7% whereas for the acid solution group the percent deviation value ranges from
0.3% to 1.6% when compared to control group. The effective electron densities, ( ) values were found to
deviate from 0.6% to 4.1% for laser applied group, from 0.6% to 2.4% for acid solution applied group when
compared to controls.
Conclusions: No significant variation in and observed when different types of treatments are applied to human teeth since the deviations observed are within estimated errors. Moreover, the studies on different types of human teeth, which are classified according to age, gender etc. would
be interesting at different energies where different partial photon interaction processes dominate.

Introduction: Impaction of permanent teeth causes serious consequences such as esthetic, phonetic and occlusal problems for the young patients. The odontoma is the most common odontogenic bening lesion of the jaws,
which is composed of hard dental tissue, epithelial and mesenchymal cells. The aim of this report was to present the management of a case with an impacted permanent central incisor due to dilaceration and odontoma.
Background: A healty 10-year old girl was referred to Pediatric Dentistry clinics of Istanbul University Faculty
of Dentistry with a complaint of an unerupted upper right central incisor. The patient was totally asymptomatic
and had no record of orofacial trauma.
Case Report: The patient had a balanced facial pattern and intraoral clinical examination revealed an Angle
Class I molar relationship.The panoramic and occlusal radiographs demonstrated an impacted maxillary right
central incisor positioned horizontally and an odontoma like lesion present around the root of the upper left
primary canine which caused the impaction of the upper left permanent canine. As treatment for impaction of
central incisor, the brackets were placed on the upper arch and the arch space loss was eliminated; then the impacted tooth was surgically exposed and a button was bonded for orthodontic extrusion. After 3 months , intraoral examination revealed that the root apex of the impacted tooth was palpable under the palatal mucosa. A
three-dimensional computed tomography (3D CT) showed that the upper right central incisor was dilacerated
with an angle of 90°. As treatment for odontoma site, odontoma is surgically removed, the primary canine and
the maxillary right central incisor were extracted and the permanent canine has been orthodontically extruded.
Conclusions: The present case highlights the importance of 3D CT diagnosis and the interdisciplinary
management for a young patient with an impacted permanent incisor with dilaceration and odontoma.

Aim: The aim of this study was to evaluate any changes in the micro-morphology of root canal dentin in primary teeth after treatments with Nd:YAG laser, ozone irradiation and four different irrigation solutions.
Methods: Study groups were prepared in palatinal root of 60 maxillary primary second molar teeth extracted
for orthodontic reasons. The root were exposed to 0.9% saline solution (control), 0.5% NaOCl, 3% H2O2,
0.4% chlorhexidine gluconate, ozone and Nd:YAG laser irradiation (n=10). All prepared teeth were studied
by using scanning electron microscopy to analyze the surface of the dentin. The scores of the SEM evaluation
were compared by using the Kruskal- Wallis and Mann-Whitney U tests.
Results: The lowest scores for the debris and smear layer were obtained in NaOCl and Nd:YAG laser, followed
by ozone (p < 0.05). In the majority of control samples treated with sterile saline solution, the dentin surfaces
were completely covered by a homogeneous smear layer. In teeth irradiated with the Nd:YAG laser showed a
clear glazed surface and some surface craters with cracks.
Conclusions: The results obtained under the experimental conditions of this study suggest that irradiation with the Nd:YAG laser has a satisfactory cleaning effect on root canal walls in primary teeth. In addition, use of ozone could be recommended because of its cleaning efficacy in the root canal dentin.

BACKGROUND: Odontodysplasia (OD) is an uncommon condition that affects the enamel and dentine of
both primary and permanent dentitions. The teeth are misshaped, pitted, and yellowish to brownish in colour, with excessive wear and underlying periapical abscesses. On radiographs, the enamel and dentine lack
contrast, rendering the tooth a ghostlike appearance. AİM: The purpose of this paper was to report a case of
regional odontodysplasia with details of clinical and radiographic features, thereby facilitating management
of this rare anomaly.
CASE REPORT: A 6-year-old girl came to our department with chief complaint of missing or unerupted permanent maxillary left central and lateral teeth. She had trauma in 1.5 years old and fell on the left side of face.
At the affected area, the gingiva was enlarged, fibrous, and tense. Radiograph showed abnormally formed
teeth with short roots. After 3 year follow up with temporary prothetic rehabilitation, periodontal surgery was
applied. Forced eruption and levelling was done during 1 year. Abnormal tooth eruption and root development
were observed in these three teeth. Root canal treatment has been completed with ProRoot MTA. An intracanal fiber post and the access cavity was restored with composite resin and zirconia ceramic crown were applied
when she was 13 year. The patient was placed on periodic recall to follow the growth and development of her
dental arch.
CONCLUSION: The best treatment option for ROD depends on the time of diagnosis, presenting symptoms and signs, functional and esthetic needs, and available treatment modalities. The affected unerupted teeth may result in the delay or failure of the process of eruption in addition to structural defects, and the possibility of bacterial infection is frequent. The treatment plan should be based
on the age of the patient, degree of anomaly, the functional and esthetical needs of individual case.

Introduction: A dentigerous cyst is the most common developmental odontogenic cyst. It is characterized by a
unilocular radiolucent lesion and are rarely seen during childhood. It is a benign and asymptomatic intraosseous lesion that affects the bones of the maxillofacial complex ,interfering with tooth eruption. Aim: The purpose
of this case report is to report a maxillar dentigerous cyst on a 12 year old boy.
Case report: A 12 years old boy was referred to Cumhuriyet University Department of Pediatric Dentistry with
the complaint of a swelling on right side of his maxilla.İntraoral examination revealed red swelling, which
produced bulging of the cortical bone of firm consistency. Radiographic examination showed a unilocular,
radiolucent area associated with the crown of an unerupted canin. The patient didn’t complain of pain and
there weren’t any inflammation symptom around the lesion.The patient’s maxillary decidious canine tooth was
extracted, so the cyst cavity was opened and the drainage was achieved. After marsupyalization spontenous
eruption of the permanent canine was expected. Patient was recalled for 6 months intervals. After 25 months
the patient’s maxillary canine eruption was determined spontaneously.
Result: In cases of this type of dental cysts it is possible to achieve spontaneus eruption of the involved permanent teeth into the dental arch even if they are badly dislocated. Simultaneous with eruption of the permanent
teeth, ossification of bone defect can take place. In this case report after 25 months of follow up spontaenous
eruptions of maksiller canine were noticed.

INTRODUCTION: PRF was used as a matrix instead of a blood clot in revascularization of the tooth with
necrotic pulp and an open apex. PRF contains concentrated growth factors such as platelet-derived growth factor, transforming growth factor, vascular endothelial growth factor, epidermal growth factor, and insulin-like
growth factor.
BACKGROUND: Some researchers showed that pulp-like tissue could be generated in a human tooth with
necrotic pulp and an open apex by using PRF as a scaffold in regenerative endodontic procedures.
CASE REPORT: A 9-year-old girl was referred to Medipol University Faculty of Dentistry, Department of
Pedodontics with complaint of dental caries. Clinical examination showed that tooth #36 had an extensive
occlusal carious lesion. Sensitivity tests (heat, cold, and electric pulp test) of the tooth gave no response. The
tooth was tender to percussion. A periapical radiograph of the tooth showed that the root apices were not fully
formed and a large radiolucent lesion was present at the periapical area of both the mesial and distal roots.
The clinical diagnosis of tooth #36 was pulp necrosis and symptomatic apical periodontitis. An immature
mandibular right first molar of a 9-year-old girl was treated with a revascularization/revitalization procedure
using either a mixture of PRF and a blood clot or a blood clot alone on the same tooth. A preparation of white
mineral trioxide aggregate (MTA) and saline solution was gently placed over the mixture of blood and PRF in
the distal canal and over the blood in the mesial canals. Seven months postoperatively, healing of the periapical lesions had improved further.
CONCLUSION: Platelet-rich fibrin might serve as a potentially ideal scaffold in revascularization of immature permanent teeth with necrotic pulps as it is rich in growth factors, enhances cellular proliferation and
differentiation, and acts as a matrix for tissue ingrowth.

Aim: Foramen mentale (FM) is one of two holes located on the anterior surface of the mandible. It permits
passage of the mental nerve and vessels which innervate the lower teeth, lip, gingiva and lower face. FM is the
determinant of the mental triangle and forms an important landmark of the human mandible. Its modal position varies according to age, ethnicity and has been cited ranging from subcanine to submolar in different populations. The purpose of this study is to evaluate the location of FM by analyzing digital panoramic radiographs
in a group of children. Methods: In this study, digital panoramic radiographies taken from 583 children (390
boy-193 girl) aged between 10-16-years-old (mean:13.4±1.7) were analyzed retrospectively. The location and
symmetry of both of the FM were evaluated according to gender and age. Additionally, the average distances
of FM to the alveolar ridge and to the inferior border of the mandible were measured.
Results: FMs were symmetrical in 500 (85.8%) children (315 boys-185 girls). Statistically important relationship was determined between the symmetry of FM and gender (p=0.001), and age (p=0.002). It was determined that 1010 FMs (86.6%) were located between the premolars, 93 FMs (8%) were in line with the first
premolar and 63 FMs (5.4%) were in line with second premolar. The calculated average distance from FM to
the alveolar ridge was of 14.1±6.5mm and to the inferior border of the mandible was 10.57±1.7mm.
Conclusions: In order to obtain effective nerve block and to avoid post-procedural neurovascular complications
in the mental region, particular attention should be paid to the morphology of the FM. Therefore, a detailed knowledge of the FM anatomy and it\’s variations in different populations is essential for dentists, orthopedicians and
anatomists alike. In our study, in most of children, FMs were symmetrical and located between the premolars.

Introduction: Mesiodens are the most common supernumerary teeth, with the incidence of 0.15% to 1.9%,
while the cause of mesiodens is not fully understood, although proliferation of the dental lamina and genetic
factors have been implicated. It can be classified on the basis of their occurrence or according to their morphology (conical, tuberculate or molariform). Conical mesiodens are generally peg-shaped, located palatally
between the maxillary central incisors, tending to displace the erupting permanent central incisors.
Background: A mesiodens is often diagnosed coincidentally during a radiological examination. However, a
mesiodens may also be diagnosed in relation to a clinically identified central diastema, delayed or ectopic
eruption of the permanent incisors, which can affect occlusion and appearance. Treatment options may include
surgical extraction of the mesiodens. If the permanent teeth do not erupt in a reasonable period after the extraction, surgical exposure and orthodontic treatment may be required to ensure eruption and proper alignment
of the teeth
Case Report: This report describes five clinical cases with a chief complaint of aesthetic concerns that were
referred to Yeditepe University Faculty of Dentistry Department of Pediatric Dentistry. Intraoral examinations
revealed delayed eruption and misalignment of the maxillary central incisor while radiographic examination
showed six mesiodens in the incisor palato region. Following orthodontic and surgical consultation, the extraction of the supernumerary teeth was carried out, the patients were called at regular intervals to monitor the
eruption of the maxillary incisor and evaluate for further orthodontic needs.
Conclusions: Delayed, ectopic or asymmetric eruption of the central incisors should alert the clinician to the
possibility of a mesiodens. The clinician should obtain accurate radiographs including panoramic and periapical
views. Usually, removal of the mesiodens in children and adolescents results in spontaneous recovery of the complications. Early diagnosis minimizes the treatment required and prevents development of associated problems.

CLINICOPATHOLOGICAL APPROACH TO THE ORAL AND MAXILLOFACIAL BONE
LESIONS IN PEDIATRIC DENTISTRY
Assoc. Prof. Dr. N.VAKUR OLGAÇ
Assist. Prof. Dr. NİHAN AKSAKALLI
In this lecture we will discuss and highlight the diagnostic and clinical features of important odontogenic lesions in pediatric dentistry.
Odontogenic Tumours; Odontogenic tumours are lesions derived from epithelial, ectomesenchymal and/or
mesenchymal elements which have been part of the tooth – forming apparatus. These tumors are found exclusively within the jaw bones or in the soft tissues overlying tooth bearing areas. These tumours may be generated at any stage of life.
Odontogenic tumours include entities of hamatomatous nature benign neoplasms some of which are aggressive and malignant neoplasms that have capable of metastasis. Odontogenic tumours accounted for between 1%
to 28% of oral lesions from various studies depending on criteria and catagories that were used for comparison.
There are some reports and studies examined odontogenic tumours in children as part of oral tumours or studied individual tumours such as ameloblastomas and adenomatoid odontogenic tumours but few have examined odontogenic tumours generaly in children.
The aim of this speech is to analyse the odontogenic tumours which are usually seen in children and adolescents.
Odontogenic Cysts; Cysts of the jaws are mostly seen in adults, therefore studied in the field of adult dentistry.
However, a number of these cysts are seen in pediatric age group, and for clinical significance and prognostic
value, they should also be studied in the field of pedodontics.
Cysts of the maxilla, mandible are divided into three groups: odontogenic cysts, nonodontogenic cysts and
pseudocysts. 98.3% of the true cysts are odontogenic cysts in maxilla and mandible. Except gingival cysts
(newborn, adult), and eruption cyst; all odontogenic cysts are found inside the bone.
From odontogenic cysts, gingival cyst of the newborn and eruption cyst are seen in children. Although is
reported that periapical cyst is seen rare under the age of 10, in a study made in Turkey, it is determined that,
61 % of periapical cysts, which’s age range is 4-85, are seen in children. In the study made in Turkey, dentigerous cyst is determined as the most common developmental cyst seen in pediatric age group. Parakeratinized
odontogenic cyst (Keratocystic Odontogenic Tumour) is the 3rd most common cyst in the jaw seen within the
pediatric age group. Parakeratinized odontogenic cyst, seen in pediatric age group and in multiple number,
it can be associated with nevoid basal cellcarcinoma syndrome (NBCCS). NBCCS is a autosomal dominant
inheritance pattern. Another developmental cysts seen in young adults is ortokeratinized odontogenic cyst.

LASER ASSISTED PEDIATRIC DENTISTRY
Assist. Prof. Dr. SERTAÇ PEKER
Dental lasers are widely used in many areas in pediatric dentistry from diagnosis to prevention, from cavity
preparation to pulp vitality tests and from endodontics to trauma cases. Laser technology can be used as an
alternative instrument that sometimes completes and at other times substitutes and assists for the traditional
techniques. With the devoloping technology dental lasers are getting importance in pediatric dentistry and
children should be considered as amongst the first patients for having laser-assisted dentistry.
Different wavelengths can be used in both hard and soft dental tissues with different clinical applications. Reduction in the use of anesthetics, analgesics and antibiotics, and in intra-operative and post-operative bleeding,
elimination the need sutures and producing faster wound healing and less scar tissue are some advantages of
dental lasers in pediatric dentistry.
In this presentation the dental lasers, soft and hard tisssue aplications in our clinic and acceptance and advantages of dental lasers both for children and parents and laser safety subjects will be reviewed.

Aim:The aim of this study was to evaluate the effects of 10 % benzalkonium chloride (BC) or 10 % cetylpyridinium chloride (CPC) incorporation to an orthodontic adhesive (OA) (Transbond XTTM) in terms of antibacterial activity and high performance liquid chromotography (HPLC) outcomes. Experimental groups (EXP)
consisted of 10 % BC (w/w) and 10 % CPC (w/w) antibacterial powders added OA where as antibacterial free
groups served as controls (CNT).
Methods: A total of 21 disc shaped specimens with the diameter of 5 mm and depth of 1 mm were prepared.
Nine samples were used for agar diffusion test (ADT) against S. mutans at 1, 7 and 14 days. The remaining
specimens (n=12) were used for HPLC test for the evaluation of releasing properties at 1, 7 and 14 days respectively. Comparisons of the EXP groups at each time sequence was done by the Mann Whitney U test for
both of the ADT and HPLC tests (p<0.05).
Results: Control groups showed neither any antibacterial activity nor releasing properties at 1, 7 and 14 day
periods. BC supplementation resulted in significantly higher (p<0.05) antibacterial effects than the CPC group
against S.mutans in all time periods. The comparison of HPLC test results of the BC and CPC groups exhibited no statistically significant differences (p>0.05) except for the 7 days period (p<0.05).
Conclusions:It may be concluded that the incorporation of 10 % BC or 10% CPC to the OA results in an increased antibacterial activity and the inhibitory effect of BC on the bacterial accumulation seems to be more
pronounced than CPC.

Fusio Liquid Dentin-No treatment (F1), Fusio Liquid Dentin-PA treatment (F2), Experimental Self-adhesive
Composite-No treatment (E1), Experimental Self-adhesive Composite-PA treatment (E2). Specimens were
kept in water at 37°C. SBS was tested 24 h later.
Results: There was no statistical significance between E1 and E2, and also between V1 and V2 (p>0.05).
However, shear bond strength of F1 was higher than the F2(p<0.05).
Conclusions: Within the limits of the current study, the tested collagen crosslinker (proanthocyanidin) did
not increase the dentin bond strengths of tested self-adhesive composites. Moreover, proanthocyanidin treatment may adversely affect the dentin bond strength, depending on the type of self-adhesive composite.

Aim: The aim of the present study was to compare mineral trioxide aggregate (MTA) with gutta-percha/AHPlus regarding their clinical and radiographical success in primary second molars without successors as root
canal filling materials.
Methods: A total of 16 patients (9 girls, 7 boys) aged 8-13 years (mean: 10.5) were selected from among patients attending the clinic of the Pediatric Dentistry Department of Ankara University in Ankara, Turkey. Each
child had at least one mandibular primary second molar without successor requiring root canal treatment. A
total of 20 teeth were randomly distributed into 2 groups using either MTA or gutta-percha/AH-Plus for root
canal treatment. The children were recalled for clinical and radiographic examination at 3.,6.,12., 18. and
24-month. Statistical analysis of the differences in treatment outcomes was performed by using the Chi-square
test.
Results: All 20 teeth were available for follow-up examinations. Clinically, there was no significant difference
in success rates between the groups at the end of 24-month follow-up (MTA: 100% and gutta-percha/AH-Plus
70%) (p>0.05). However, there was a significant difference in radiographical success between the groups
MTA with 90% success and gutta-percha/AH-Plus showing 30% success at the end of 24-month follow-up
(p<0.05). Radiographic failures were significantly higher than clinical failures (p<0.05). The most commonly
observed radiographic failure was pathologic root resorption.
Conclusion: MTA was superior to gutta-percha/AH-Plus and can be recommended for use in root canal treatment of primary second molars without successors depending on better tooth survival.

Aim: The aim of the present study is to evaluate the histological features of the primary teeth which pulpotomized with calcium hydroxide (CH) and to compare the histological results with the clinical and radiographic
outcomes.
Methods: Six failed pulpotomized teeth with CH treated in Selcuk University Faculty of Dentistry, Department of Pediatric Dentistry were extracted. Following the extraction the teeth were immediately preserved in
10% buffered formalin and demineralized in 5% nitric acid solution. After dehydrating in ascending concentrations of ethanol, the teeth were embedded in paraffin and selected sections were stained with hematoxylin
and eosin. The prepared slides were examined under a light microscope. Then the histological results were
analyzed and compared with clinical and radiographic outcomes.
Results Five of the six teeth were extracted because of signs and symptoms of infection: pain, mobility and
swelling. When radiographic outcomes were examined, five of the six teeth had periradicular pathology. Only
one tooth had internal resorption and intra-canal calcification. After histological procedures, the findings show
that calcified barrier (dentine bridge) formation was seen in two of the teeth. Dentin apposition was seen in
three of the teeth. There was also histological evidence of resorption in the root canal walls of five teeth. Interradicular side of dentin structure showed that external resorption was another finding about failure. Inflamed
pulp was identified all specimens.
Conclusions In conclusion, this study showed that the infection, whether pre-existing or occurring as
a complication of CH pulpotomy treatment (post-operative) was the main reason of treatment failure. Internal and external resorptions were seemed to be secondary outcomes of persistent infections.

Aim: The aim of the present study were to evaluate the effect of various irrigating solutions on the removal of
calcium hydroxide mixed with 2% chlorhexidine gel from an artificial groove created in a root canal and the
generation of orange-brown precipitate in the remaining calcium hydroxide mixed with 2% chlorhexidine gel
after irrigation with the various irrigating solutions.
Methods: The root canals of 48 mandibular premolars were prepared using rotary instruments up to size F4.
The roots were split longitudinally and a standardized groove was prepared in the apical part of 1 segment. The
root halves were reassembled and calcium hydroxide mixed with 2% chlorhexidine gel medicament was placed into the grooves. The roots were randomly divided into 4 experimental groups specified by the irrigation
solution used: 1% NaOCl, 17% EDTA, 7% maleic acid, and 10% citric acid (n=12). The amount of remaining
medicament was evaluated under a stereomicroscope using a 4-grade scoring system. After irrigation, the specimens were also evaluated for the presence/absence of orange-brown precipitate. Data were analyzed with
Kruskal-Wallis and Mann- Whitney U tests (P=.0083).
Results: Solutions of 7% maleic acid and 10% citric acid were superior to solutions of 1% NaOCl and 17%
EDTA in removing calcium hydroxide mixed with 2% chlorhexidine gel (P<.0083). There were no significant
differences among the other groups (P>.0083). Orange-brown precipitate was observed in all specimens of the
NaOCl group but in no specimens in the other groups.
Conclusions: Irrigation solutions of 7% maleic acid and 10% citric acid were more effective in the removal of
calcium hydroxide mixed with 2% chlorhexidine gel than those of 1% NaOCl and 17% EDTA. Orange-brown
precipitate was found in all specimens of the NaOCl-irrigated groups but not observed in the other three groups.

Aim: One-step apexification has been reported as an alternative treatment method with more benefits than the
use of long-term calcium hydroxide for teeth with open apex. This invitro study evaluated and compared the
apical microleakage of ProRoot MTA(Dentsply), DiaRoot BioAggregate (DiaDent) and Biodentin (Septodont) in endodontic treatment of teeth with simulated immature apices.
Methods: Forty-five bovine maxillary incisors roots were prepared to simulate immature teeth and randomly
divided into three groups (n=15). Following root canal preparation, the specimens were obturated with; Group
I: ProRoot MTA; Group II: DiaRoot BioAggregate (DiaDent); Group III: Biodentin(Septodont). Apical microleakage was assessed using dye penetration technique. The linear dye penetration was measured at X30
magnification and the data were analyzed with ANOVA test.
Results: Group I showed the lowest apical leakage with a mean dye penetration of 4.64 mm while the leakage
was the highest in Group II with a mean dye penetration of 5.45 mm. The difference between Group I and
Group II was statistically significant (p<0.05).
Conclusions: The findings of the present study suggest that MTA showes the best sealing ability when used for
the obturation of immature apices.

Aim: The aim of this study was to investigate the disinfection effect of Er,Cr:YSGG laser using radial firing
tips with and without NaOCl solution.
Methods: In total eighty one extracted human mandibular premolar teeth were used. After root canal preparation and sterilization, the samples were inoculated with E. faecalis for 24 hours. The specimens were divided
into 4 experimental groups. Group 1 (n=25) was irradiated with 2 W laser, group 2 (n=25) was irradiated with
0.75 W laser in combination with 2.5 % NaOCl, group 3 (n=25) was irrigated with 5 % NaOCl and group 4
(n=6) was not treated. Statistical analysis was performed by using Wilcoxon Signed Ranks, Mann-Whitney U
and Kruskal-Wallis H tests.
Results: The combination of 0.75 W laser with 2.5 % NaOCl regime was found to be just as effective at inhibiting the growth of E. faecalis and sterilization of all root canals as 5 % NaOCl irrigation. 2 W laser had
significant bactericidal effect in infected root canals however it did not eradicate all bacteria. The SEM observations were in accordance with the microbiologic findings.
Conclusions: When the toxic effects of NaOCl is considered, combination of 2.5 % NaOCl and 0.75 W laser
treatment can be a valuable cleaning tool to be used in root canal treatment.

“GLASS CARBOMERS” IN PEDIATRIC DENTISTRY
Dr. Mine Koruyucu
Istanbul University, Faculty of Dentistry, Department of Pedodontics, Istanbul, TURKEY
Introduction: The perfect restorative filling material would be the one that can be replaced by natural tooth
enamel and dentin. The research for a perfect restorative filling material has been ongoing.
Aim: The purpose of this presentation is to report usage of Glass Carbomer fillings and sealants in Pediatric
Dentistry.
Method: Glass Carbomer® is a relatively new commercially available glass ionomer cements used as a restorative filling material and fissure sealant that is designed to deliberately remineralize in the mouth. It is claimed
to contain nanocrystals of calcium fluorapatite, which can act as nuclei for the remineralization process and
initiate the formation of fluorapatite. The glass has a much finer particle size compared to conventional glass
ionomer cements which is thought to aid its dissolution and ultimate conversion to fluorapatite. Compared to
conventional glass ionomer cements and resin-modified glass ionomer cements are characterised by having
a longer working time, a rapid set, improved aesthetic appearance and translucency and an increased early
strength. The longevity and strength of cements partly depend on their mechanical properties. The researches
on the subject have been evaluated.
Conclusion: It is considered to be used as an alternative to current materials in pediatric dentistry

Introduction: A dentigerous cyst is an odontogenic cyst - thought to be of developmental origin - associated
with the crown of an unerupted tooth. Such cyst remain initially completely asymptomatic unless when infected. The purpose of this case report is to describe the diagnosis and management of two siblings with dentigerous cyst associated with the tooth buds of permanent teeth.
Case report: A 8-year-old female in 2008 and her 8-year-old brother in 2011, 3 years later at his sister’s age,
came to our clinic. The girl’s chief complaint was swelling and pain on right lower second primary molar
while three years later the boy’s complaint was swelling and pain on the right maxillar canine. No systemic
diseases or syndromes were present. Based on clinical and radiographical examinations, a provisional diagnosis of dentigerous cyst was made. The treatment instituted was the marsupialization with the extraction of
the involved primary teeth. The specimen from the cavity was sent to histopathological examination and the
findings confirmed diagnosis of dentigerous cyst. Due to the large extent of the lesion, the acrylic resin drain
was maintained for 30 days. Through the following period, a daily irrigation of the cystic cavity with saline
solution was carried out to prevent a secondary infection within the cystic cavity. A follow-up of 6 years for the
girl and 3 years of the boy showed no signs of recurrence. The girl’s second premolar is on occlusion without
any orthodontic treatment.
Results: Marsupialization of dentigerous cyst is completely effective and safe. This treatment allowed rapid healing
of the lesion and eruption of the permanent teeth with minimum orthodontic therapy or without orthodontic therapy.

Aim: The foramen of Huschke (FH) (foramen of tympanicum) is an anatomic variation in the tympanic portion of the temporal bone due to a defect in ossification normal bone physiology in neonatal or postnatal period.
This study aimed to analyze and assess the presence, location and diameter of the FH in a pediatric population
through cone beam computed tomography (CBCT).
Methods: Reformatted axial, coronal and sagittal slices of 354 individual CBCT images were analyzed. Measurements were done in the axial plane as well as on the reconstructed coronal and sagittal planes. Differences
in FH incidence by measurements, sex, side, and location were statistically evaluated.
Results: We found a FH in 123 (34.7%) of 354 patients. This was unilateral in 60 patients (16.9%) and bilateral
in 63 patients (17.8%). A higher frequency of FT was observed in girls (42.1 %) than in boys (27.8 %) (p =
0.003). The mean axial diameter was 1.91 mm and mean sagittal diameter was 2.02 mm. Gender significantly
influence the diameter on left sagittal side (p: 0.046).
Conclusions: Our study is the first study in the literature evaluating FH in a pediatric population. The present
study provides new information to the literature concerning the identification of the presence of FH in a pediatric population. This finding may assist clinicians for understanding the morphology and preventing possible
complications in this region.

Introduction : Odontogenic infection is a frequently occurring infectious process known to the health practice.
The fate of the infection depends on the virulence of the bacteria, host resistance factors and regional anatomy.
A bacterial infection of necrotic dental pulp tissues induces inflammation in the tissues at the apex tooth.
Aim : The aim of this study is to determine the bacterial species of odontogenic infections and bacterial composition of the microbiota from acute and chronic dental infections in young children.
Materials and methods: In this study were included 70 children aged 5-15 years with acute and chronic odontogenic infections with both dentitions After clinical examination and radiological verification,the caused
tooth was extracted. After taking the sample from tooth alveoli , the material is sent to the microbiological
laboratory for bacterial growth and cultivation. Identification and separation of bacteria was done by VITEK
2 cards (BioMeriux-France)
Results : Odontogenic infection is poly microbial ,from samples analyzed in terms of microbial infections as
well as acute and chronic were isolated aerobic and anaerobic bacteria.From the aerobic group bacteria have
dominated: Streptococci (mitis, oralis, anginosus) while from the anaerobic group have dominated Actinomyces (mayeri, naeslundii) and Clostridium group .Numerous novel, uncultivated and fastidious organisms have
been identified as potential pathogens with the use of non-culture techniques.
Conclusion : The role of bacteria in lesion pathogenesis is undeniable. Certain combination of anaerobic and
aerobic streptococci occurred frequently.The relative importance of each of these bacterial species in mixed
infections requires further investigations.

Aim: Infraorbital ethmoid cells are defined as air cells situated beneath the ethmoid bulla along the roof of the
maxillary sinus and the most inferior portion of the lamina papyracea, including air cells located within the
ethmoid infundibulum. The aim of this retrospective study was to evaluate the frequency, volume, and surface
area of infraorbital ethmoid cells on cone-beam computed tomography (CBCT).
Methods: In this retrospective study, 368 CBCT evaluations were determined for infraorbital ethmoid cells.
One CBCT examination was carried out for each of the patients and interpreted for the presence of infraorbital
ethmoid cells. Volumetric measurements were performed using CBCT scans.
Results: In the 368 CBCT evaluations, 143 (38.8 %) were noted as having infraorbital ethmoid cells. The
majority of the cells were round in shape. The frequency of unilocular infraorbital ethmoid cells occurring
unilaterally was highly significant. There were no significant differences in the volume and surface area of
right and left infraorbital ethmoid cells between boys and girls.
Conclusions: Infraorbital ethmoid cells were well demonstrated and the volume and surface area of infraorbital ethmoid cell could be measured on CBCT scans. These cells may provide useful differential diagnoses for
patients suffering from orofacial pain of sinus origin.

Abstract Introduction: Odontogenic infections caused by dental diseases of teeth in young children are related
to several factors. These factors can be physiological or influenced by children lifestyle . Therefore, it is often
difficult to identify sole factors causing the infection. Kosovo faced a long period with lack of epidemiological
data which can help identify potential factors to establish a prevention dental care in our institutions. Aim:
The aim of this study is to generate epidemiological data on the incidence of orofacial infections and find the
relationship between different age groups, gender and predisposed teeth.
Material and methods: The study includes 707 children from schools and nurseries, divided in three age
groups, 4-5 years (n=121), 7-9 years (n=249) and 10+ (n= 337). Evaluation of dental was done using DMFT
score. In addition, dental lesions were assessed via anamnesis and confirmed with x-ray. Statistical analysis
are conducted to assess the relationship with age, gender and predispose teeth.
Results: From the total of 707 examined children, 111 of them had odontogenic infections, both acute and
chronic. dmft for the age group 4-5 years is 7.05, and for the other group 7-9 years old is 6.5 and for the 10+ is
4.55. There was not found a significant relationship of frequency of infection between female and male gender
(P>0.01). Significant differences are found between different age groups (p<0.05). Most predisposed primary
tooth is found to be second molar (49.7%) and least infected primary tooth is canine (2%). 1st molar is most
predisposed tooth between permanent teeth (66.1%).
Conclusion: These results suggest that odontogenic infections are frequent in children in Kosovo. Significant
relationships found in this study can support preventive oral health actions in educational institutions. Data
on tooth predisposition suggest further studies to be done and assess the causality. Key words: odontogenic
infections, children, age, gender, predisposed teeth.

Introduction : Minimal intervention dentistry (MID) is a modern approach in caries prevention, detection, and,
management. This approach offers considerable benefits over traditional dentistry. MID allows early detection
of disease. A rigorous and systematic approach to caries diagnosis is essential to establish a care plan for the
disease and to identify preventive measures and to reduce restorative procedures. The aim of this presentation
is to address advances in key areas related to caries detection tools in pediatric dentistry.
Method and discussion: A comprehensive literature search for publications discussing this subject was performed using the search terms: fluorescence, digital radiography, near-infrared (NIR) transillumination, and
Cone Beam Computed tomography (CBCT) and pediatric dentistry. The methods and place of modern tools
actually recommended for clinical diagnosis are discussed and illustrated.
Conclusion: Caries detection tools can aid the pediatric dentist and the pediatric patient. These tools are potentially useful in regular control visits to monitor the progression or regression of early lesions

BÜYÜK AZI KESER HİPOMİNERALİZASYONU’NDA KORUYUCU UYGULAMALAR VE
REZİN RESTORASYONLARIN BAŞARISINI ARTTIRAN YÖNTEMLER
Prof. Dr. HAYRİYE SÖNMEZ
Büyük Azı Keser Hipomineralizasyonu (BAKH-MIH) ilk defa 1970’lerde birinci daimi büyük azı ve keser
dişlerin hipomineralizasyonu olarak bildirilmiş ve farklı terimlerle ifade edilmiştir. 2003 yılında Atina’da
yapılan bir toplantıda BAKH (MIH) terimi ve klinik özellikleri üzerinde fikir birliğine varılmıştır. Farklı ülkelerde BAKH ‘nu araştıran çalışmalar, %2.8’den %40.2’ye varan farklı prevelans değerleri bildirmektedir.
Beyaz- krem renginden sarı ve kahverengine kadar değişen, sınırları belirgin defektlerin gözlendiği bu durumun etyolojisinde ameloblastların fonksiyonunu etkileyen prenatal, perinatal, neonatal problemlerin yanı sıra
erken çocukluk döneminde geçirilen hastalıklar ve çevresel faktörler sorumlu tutulmuştur.
Özellikle büyük azı dişlerde tüberkül tepelerinde gözlenen defektlerde hipomineralize mine çiğneme basıncına dayanamayıp kolayca dişten kopar ve gıdaların birikebileceği retansiyon yerlerini oluşturur. Dişlerdeki
hassasiyet çocuğun dişlerini fırçalamadan kaçınmasına neden olur ve dişlerde çürükler oluşur.
Bu sunumda BAKH’nun ülkemizdeki prevelansı, etyolojik nedenleri, tedavi ve koruyucu uygulamalar anlatılacaktır.

varedilmesinin karşılığı olarak yerleşmiş bir kavram halini almıştır. Meslek üyelerinin birbirleri ile ilişkilerinde bağlı kalmaları gereken etik ilke ve kurallar ve bunların çiğnenmesinden doğan istenmeyen durumla
da Diş Hekimliği Etiği’nin incelediği ve değerlendirdiği durumlardır. Her birimiz bir diğer Diş Hekimi’nin
meslektaşıyız. Meslektaşlık, meslek yaşamında meslek üyeleri ile bazı normlara bağlı kalarak ilişkide olmak
anlamı taşır. Meslektaşlık bilinci, Meslek Onuru ve Meslek Etiği gibi kavramları yaşatmada önemli bir yer
tutar. Çeşitli ülkelerin Deontoloji Tüzükleri, meslektaşlık ilişkilerine eğilirken daha çok, meslektaşça olmayan davranışları tanımlamaya yönelmiştir: Meslektaş ve onun becerisi hakkında küçültücü sözler söylemek,
meslektaşın mesleki bir konudaki yardım talebini geri çevirmek gibi. Meslektaşça olan ise, meslek üyelerinin
birbirleri ile saygı temelinde, barışçıl duygular içinde, ön yargısız ve güvene dayalı bir işbirliği içinde olabilmeleridir. Meslektaşlık kavramına bağlılık, bir yandan meslek üyelerin birbirleri ile ilişkilerinde bir düzen
sağlarken, diğer yandan da mesleğin dışarıya karşı saygınlığını pekiştirir. Ancak meslektaşlığı gözetmek, hastanın çıkarlarını ikinci plana atmak demek değildir. Örneğin bir tedavi hatası Bilirkişi karşısına geldiğinde,
meslektaşlığı gözetmek gerekçesiyle örtbas edilemez. Bu durumda Bilirkişi, hem hastanın iyiliğini, hem de
mesleğin saygınlığını gözetme yükümlülüğü içinde, hatayı ortaya koyacaktır. Bu sunumda benzeri örnekler
verilerek, Diş Hekimliği’nde Meslektaşlık kavramı etik açıdan irdelenecek, meslektaşlar olarak bu konudaki
ortak yükümlülüklerimize vurgu yapılacaktır.

Tüm dünyada olduğu gibi ülkemizde de ‘özel bakım gerektiren çocuklar’ birçok sosyal ve sağlık sorunları
yaşamaktadır. Ailelerin veya bakıcıların çocukların genel sağlık problemlerine odaklanması sonucu ağız ve
diş sağlığı genellikle ikinci plana itilmektedir. Ağız ve diş sağlığı problemleri sıklıkla hayat kalitesini olumsuz yönde etkileyecek safhaya gelene kadar beklenmektedir. Bu da özel bakım gerektiren çocukların tedavilerini hem hekim hem de hasta açısından daha zor hale getirmektedir.
Özel bakım gerektiren çocuklardaki ağız ve diş kaynaklı sorunlar, engel tipine göre farklılıklar göstermektedir. Bu yüzden tedavi planı hastanın engel durumu göz önünde bulundurularak yapılmalıdır. Gerek tedavi
maliyetlerinin yüksek olması, gerek özel bakım gerektiren hasta grubunun tedavi ihtiyaçlarının fazlalığı koruyucu diş hekimliği uygulamalarını özellikle bu grupta ön plana çıkarmaktadır. Bu nedenle bu çocuklarda
dişlerin ilk sürme sürecinden itibaren olası ağız ve diş problemlerinin önlenmesi ilk hedef olmalıdır. Koruyucu tedaviler çocuklar için daha kabul edilebilir yöntemlerdir ve hekime güvenini artırarak iletişim kolaylığı
sağlar. Diğer bir hedef ise bu bireylerde acil diş hekimliği uygulamalarının standart olarak her yerde sağlanabilmesidir. Ülkemizde sağlık hizmetlerine ulaşımı kolaylaştıran politikaların yanında özel bakım gerektiren
hasta grubuna hizmet verecek diş hekimlerinin de bu konuyla ilgili eğitimine ihtiyaç duyulmaktadır.

Gazi Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı, Ankara
Ülkemizde erken çocukluk dönemi çürüğünün yaygınlığı halk sağlığı açısından ciddi bir risk oluşturmaktadır. Bebekler diş hekimlerinden çok önce çocuk doktorları tarafından muayene edilmektedir ve bu bağlamda
çocuk doktorlarının ağız sağlığının geliştirilmesine yönelik annenin eğitiminde eşsiz yeri ve önemi vardır.
Çocuk doktorları bebeğin birimci yılda 5, ikinci yılda ise en az 3 kez kontrolden geçmesi gerektiğini vurgulamaktadır. Öte yandan diş hekimliğinde koruyucu uygulamalar kapsamında başarılı bir sonuç elde etmek
için bu uygulamalara doğumdan sonraki 1 yıllık süreçte başlanmalıdır. Ancak çocuk doktorları tarafından
hayatın ilk 2 yıllık döneminde düzenli olarak kontrolleri yapılan çocuklar dahi çocuk diş hekimlerine yönlendirilmemekte ve toplumsal olarak ağız ve diş sağlığı açısından koruyucu önleyici dental alışkanlıkların
yerleşmesi ve kazandırılması sağlanamamaktadır. Çocuk doktorlarının bebek ve çocuklarda ağız-diş sağlığı
konusunda farkındalıklarının ve yaklaşımlarının değerlendirilmesi amacı ile bölümümüz tarafından yürütülen çalışmanın sonuçları değerlendirildiğinde hekimlerin ağız-diş sağlığı konusunda aldıkları eğitimi yetersiz
buldukları ve geliştirme ihtiyacı duydukları (%94) bulgulandı. Öte yandan, çocuk sahibi olmak, günlük sınırlı hasta sayısı ve mesleki deneyimin bilgi, farkındalık ve pratik yaklaşım üzerinde olumlu etkileri olduğu
saptandı.
Toplumda ağız ve diş sağlığının geliştirilmesi bebeklik çağında özellikle annenin eğitimi ile mümkündür.
Bebek ve çocukların sağlık ihtiyaçlarının giderilmesinde çocuk doktorlarının ilk basamağı oluşturduğu ve
etkinlikleri göz önüne alındığında bu bağlamda diş hekimleri ile yapılacak ortaklaşa çalışmalar gelecek nesillerin ağız ve diş sağlığına önemli katkılar sağlayacaktır.

ÇOCUK DENTAL PROFLAKSİ KLİNİĞİ
Yard. Doç.Dr. Sera DERELİOĞLU
Atatürk Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı, Erzurum
Tıp fakültesinde tedavi ve koruyucu sağlık hizmetlerinin ayrı verilmesi ve her iki alanda da verimin artması
projemizin düşünce kaynağı olmuştur. Bu amaçla hazırladığımız projeden gelen kaynakla üç dental ünite
alınmış, bu üniteler sadece proflaksi uygulamaları için ayrılmış ve kliniğimize randevu almak için başvuran
her hastaya ve 6 aylık aralıklarda daha önce de proflaksi yapılan hastalara beklemeden ve randevu bile vermeden proflaksi hizmeti ve beraberinde oral hijyen eğitimi vermekteyiz. Bugün geldiğimiz nokta sadece iki yıl
içinde, daha önceleri bölgemizdeki hastalarımızın büyük bir çoğunluğu dental profilaksinin ne olduğunu bile
bilmezken, şu an 6 ay sonra sadece proflaksi yaptırmak için kliniğimize başvurmanın ve bu şekilde sadece diş
ağrısıyla diş hekimine gitmemesi gerektiğinin bilincine varmışlardır.
FİSSÜR ÖRTÜCÜ VE TOPİKAL FLORİD UYGULAMALARININ RUTİN DENTAL KLİNİK
UYGULAMALARDAN AYRILMASI:İLK KLİNİK SONUÇLAR
AMAÇ: Bu çalışmanın amacı çocuk diş hekimliğinde rutin dental restoratif klinik uygulamalardan fissür
örtücü ve topikal florid uygulamalarını içeren dental proflaksi uygulamalarının ayrılmasının dental proflaksi
uygulamalarının sayısal artışına etkisinin karşılaştırılmasıdır.
GEREÇ-YÖNTEM: Bu çalışmanın verileri Ekim 2011- Mayıs 2012 tarihleri (klinik uygulama ayrımı yapılmadan önce) ve Ekim 2012-Mayıs 2013 (klinik uygulama ayrımı yapıldıktan sonra) tarihlerini kapsadı. Veriler
Atatürk Üniversitesi Diş Hekimliği Fakültesi database kayıtlarından elde edildi.
Kayıtlardaki çocukların yaş aralıkları 36 ay-12 yıl arasındaydı. Topikal florid uygulamaları % 1.23 APF (kaşıkjel yöntemi) veya %5 NaF (vernik-brush yöntemi) şeklindeydi. Fissür örtücü uygulamaları ise Bis-GMA esaslıydı. Elde edilmiş olan sekizer aylık sayısal veriler istatistiksel olarak karşılaştırıldı.
155
BULGULAR: Hem fissür örtücü hem de topikal florid uygulamaları için klinik uygulama ayrımı yapılmadan
önce ve klinik uygulama ayrımı yapıldıktan sonraki veriler arasında istatistiksel olarak anlamlı farklılık ve
korelasyon bulunmuştur.
(Fissür örtücü için;x2=257.81, p=0.000; spearman korelasyon=0.028, p=0.000. Topikal florid uygulamaları
için; x2=543.903; p= 0.000; spearman korelasyon=0.048, p=0.000).
Aylara göre değişim yüzdeleri ise; fissür örtücü için %381.75’ten %720.07’ye kadar; topikal florid uygulamaları için; %282.78’den %1101.81’e kadar değişimler göstermiştir.
SONUÇLAR: Bu çalışmanın sınırları içerisinde, profilaksi uygulamaları rutin dental uygulamalardan
ayrıldığında profilaksi uygulamalarının sayısal olarak belirgin artışlarla karşılaşılabilir. Bu durum özellikle
dmft/DMFT indekslerinin yüksek ve genç nüfusun fazla olduğu ülkelerde dental profilaksi uygulamalarının
yaygınlaştırılması açısından yararlı olabilir.Bununla beraber dmft/DMFT değişimlerinin gözlemlenmesi
zaman alıcı bir süreçtir.

Amaç: Bu in vitro çalışmanın amacı, üç farklı renkteki kompomerin polimerizasyonu sonrası reaksiyona girmemiş artık monomer salım miktarlarının on bir farklı zaman periyodunda (10. dakika, 1. saat, 3. saat, 12.
saat, 1. gün, 3. gün, 7. gün, 11. gün, 14. gün, 21. gün ve 30. gün) belirlenmesi ve renklerin polimerizasyon
üzerine etkisinin incelenmesidir.
Yöntem: Bu amaçla üç çalışma grubu oluşturulmuştur: Grup 1; geleneksel diş rengindeki kompomer Dyract
XP’nin (Dentsply DeTrey, Konstanz, Almanya) A2 rengi, Grup 2; renkli kompomer Twinky Star’ın (VOCO,
Cuxhaven, Almanya) pembe rengi ve Grup 3; Twinky Star’ın mavi rengi. Her grup için standart teflon kalıplar
kullanılarak örnekler hazırlanmış (n=10) ve kompomerler üretici firmanın önerileri doğrultusunda bir LED
ışık kaynağı kullanılarak polimerize edilmiştir. Her bir zaman periyodunda reaksiyona girmemiş artık monomer salım miktarları (HEMA, BIS-GMA, TEGDMA, UDMA ve toplam artık monomer) yüksek basınçlı likit
kromatografisi (HPLC) kullanılarak tespit edilmiştir. Tüm veriler istatistiksel olarak analiz edilmiştir.
Bulgular: Tüm gruplarda zaman periyodu artıkça artık monomer salım miktarları da artmıştır. Kompomerlerden en çok salınan artık monomerin BIS-GMA, en az salınan artık monomerin ise HEMA olduğu tespit
edilmiştir. 30 günlük zaman periyodunda BIS-GMA, UDMA ve toplam artık monomer salımı en çok Grup 3
ve en az Grup 1’de, HEMA salımı ise en çok Grup 1 ve en az Grup 3’de tespit edilmiştir. TEGDMA salımı en
çok Grup 3’de belirlenirken, Grup 1’de hiç olmamıştır.
Sonuçlar: Sonuç olarak, kompomerlerde renk faktörünün artık monomer salımı üzerinde etkili olduğu tespit edilmiştir. A2 renk kompomer, pembe ve mavi renk kompomerlere oranla daha az toplam artık monomer salımı göstermiştir. Bu nedenle renkli kompomerlerden polimerizasyon sonrası artık monomer salım
miktarının azaltılabilmesi için polimerizasyonun güçlendirilmesine yönelik ilave önlemler alınmalıdır.

ETKİNLİĞİNİN DEĞERLENDİRİLMESİ
Gamze TOPÇUOĞLU, Erciyes Universitesi - Pedodonti,
Kenan CANTEKIN, Erciyes Üniversitesi - Pedodonti,
Amaç: Çocuklardaki dental tedavilerde kullanılan topikal anestezikler, iğne enjeksiyonu sırasındaki ağrıyı
büyük ölçüde azaltarak hastanın tedaviyi kabul edilebilirliğini arttırmaktadır. Bu klinik çalışmanın amacı,
pediatrik mukozal atomizasyon cihazı (LMA MADdy) ile uygulanan % 10’luk lidokain ile % 2.5 lidokain ve
% 2.5 prilokain kombinasyonu olan topikal anestezik kremin (EMLA %5) etki hızlarının ve anestezi derinliklerinin karşılaştırılmasıdır.
Gereç ve Yöntem : Çalışmamız, 7-10 yaş arasındaki sağlıklı ve infiltratif anesteziyi gerektirecek çürüğe sahip
50 hastanın, 100 maksiller süt molar dişi üzerinde gerçekleştirildi. Çalışmaya her hastanın çürüklü sağ ve sol
iki süt molar dişi dahil edildi. 100 adet diş EMLA ve LMA MADdy uygulanmak üzere iki gruba ayrıldı. Anestezikler 10, 30, 60 ve 120 sn süreyle uygulanarak değerlendirildi. Tedavisine başlanacak olan hastanın ilgili
diş mukozasına LMA MADdy ile % 10’luk lidokain püskürtüldü. Aynı hastanın diğer maksiller bölgesindeki
süt molar dişinin mukozasına da EMLA krem uygulandı. Hastanın 10, 30, 60 ve 120 sn sonlarında her iğne
penetrasyonundan sonraki reaksiyonları nabız değerleri ve görsel olarak da modifiye VAS skalası kullanılarak
incelendi. Gruplar arasındaki farklılıklar eşleştirilmiş- t testi kullanılarak değerlendirildi.
Bulgular: 10 sn’ de atomize lidokain kullanımında nabız değerlerinde belirgin artma gözlenirken, 30. ve 120.
saniyelerde azalma gözlenmiştir. Benzer şekilde ilerleyen zaman aralıklarındaki EMLA uygulamasında da
nabız değerleri düşmüştür. İki grup karşılaştırıldığında tüm zaman aralığındaki nabız değerleri atomize lidokainde EMLA’dan daha düşük çıkmıştır. 30, 60 ve 120 sn de aradaki fark önemli bulunurken (p<0,05) ; 10.
saniyede ise anlamlı fark bulunmamıştır (p>0,05). Vas değerleri, tüm zaman aralıklarında atomize lidokainde
EMLA’dan daha düşük çıkmıştır. 10. ve 30. saniyedeki skala değerleri arasındaki fark EMLA ve atomize lidokain için önemli bulunmazken (p>0,05) ; 60. ve 120. saniyelerde önemli fark bulunmuştur (p<0,05).
Sonuçlar: Bu çalışma sonucunda LMA MADdy klinik olarak başarılı bulunmuş olsa da hakkında daha fazla
çalışma yapılmasına ihtiyaç vardır.

Amaç: Çalışmanın amacı, farklı içeriklerdeki cam iyonomerlerin sağlam ve çürükten etkilenmiş süt dişi dentin
yüzeylerine mikro-gerilim bağlanma dayanımlarının ve bu materyallerin flor salım/reşarj özelliklerinin değerlendirilmesidir.
Gereç ve Yöntem: Çalışmada kullanılan cam iyonomer materyallerin bağlanma dayanımlarının değerlendirilmesi amacıyla 48 adet süt molar dişe okluzal kavite hazırlandı. Örneklerin yarısına pH-siklus işlemi uygulanarak çürükten etkilenmiş dentin dokusu elde edildi. Sağlam ve çürükten etkilenmiş dentin yüzeyine sahip
diş örnekleri rastlantısal olarak 3 gruba ayrılarak restore edildi: GC Equia (GC, Tokyo, Japan), GCP Glass Fill
(GCP Dental, Mijlweg, Netherlands), Ketac N100 (3M ESPE St. Paul, MN, USA). Restorasyonu tamamlanan
örneklerden elde edilen test çubukları Universal test cihazı kullanılarak mikro-gerilim testine tabi tutuldu.
Materyallerin flor salım/reşarj özelliklerinin değerlendirilmesi amacıyla; her materyal için 10’ar adet olacak
şekilde hazırlanan disk şeklindeki örnek deiyonize su içerisine bırakıldı. Örneklerden salınan flor iyonu miktarı, 1, 2, 4, 8, 15, 22, 29, 36, 43 ve 49. günlerde flor-spesifik elektrot ve iyon analizörü aracılığıyla ölçüldü,
her ölçüm aralığında deiyonize su yenilendi. Bu periyodun ardından her bir örnek %1,23 APF solüsyonu ile
4 dakika reşarj edildi. Reşarj sonrası örneklerin flor salım değerleri 10 farklı zaman aralığı için tekrar değerlendirildi.
Bulgular: Sağlam dentin dokusunda; en yüksek mikro-gerilim bağlanma değeri GC Equia ile elde edilirken
(P<0.05), GCP Glass Fill ve Ketac N100’ün bağlanma değerleri arasında anlamlı bir fark olmadığı belirlendi
(p>0.05). Çürükten etkilenmiş dentin yüzeyinde ise en yüksek bağlanma gerilimi GC Equia ve GCP Glass Fill
ile elde edilirken (p>0.05), Ketac N100 en düşük bağlanma gerilimini göstermiştir (P<0.05). Başlangıç flor salımı ve flor reşarjı sonrası, ölçüm yapılan tüm periyodlarda, GC Equia en yüksek flor salım değerini verirken,
Ketac N100 en düşük flor salımını gerçekleştirdi.
160
Sonuç: Test edilen tüm materyallerin flor salımı zaman içerisinde azalırken, reşarj sonrası flor salımının bir
miktar arttığı belirlendi. Cam iyonomer simanların çürükten etkilenmiş dentine bağlanma değerlerinin sağlam
dentine kıyasla daha düşük olduğu tespit edildi.

Amaç: Bu çalışmanın amacı, fissür örtücü olarak kullanılan farklı içeriklere sahip cam iyonomer materyallerin, diş dokusuna bağlanma dayanımlarının, penetrasyon kabiliyetlerinin, materyal ile diş yüzeyi arasındaki
mikrosızıntı ve remineralizasyon kapasitelerinin değerlendirilmesidir.
Gereç ve Yöntem: Çalışmada üç farklı cam iyonomer esaslı fissür örtücü materyal (Fuji Triage, Fuji VII EP ve
GCP Glass Seal) kullanıldı. Mikrosızıntı değerlendirmesi için, diş yüzeyine uygulanan fissür örtücü materyaller termal-siklus işlemi sonrasında, %0,5 bazik-fuksin solüsyonu içerisinde bekletildi ardından elde edilen kesitlerdeki sızıntı miktarları dijital bir analiz programı (LabSens, Olympus, Center Valley, PA, USA) yardımıyla stereomikroskop altında değerlendirildi (n=120). Fissür örtücü materyallerin penetrasyon kabiliyetlerinin
belirlenmesi amacıyla okluzal yüzeylere uygulanan materyallerden bukko-lingual olarak elde edilen kesitler,
dijital analiz programıyla incelendi ve doldurulmamış alan oranları hesaplandı (n=120). Test edilen materyallerin makaslama bağlanma dayanımları Universal test makinesi aracılığıyla ölçüldü (n=60). Materyallerin
remineralizasyon kapasitelerinin değerlendirmesi için; başlangıç lezyonu oluşturulan mine yüzeyleri üzerine
uygulanan materyallerin, bu yüzeylerde oluşturduğu Ca/P ve flor değişimleri 2, 4 ve 6 haftalık periyodlar için
enerji dağılımlı x-ışınları analizi (EDS) ile belirlendi. Veriler istatistiksel olarak analiz edildi (α=0.05).
Bulgular: Mikrosızıntı değerleri açısından tüm fissür örtücü materyaller arasında istatistiksel olarak anlamlı
fark bulundu: GCP Glass Seal>Fuji VII EP>Fuji Triage (p<0.05). En yüksek doldurulmamış alan oranını GCP
Glass Seal gösterirken, Fuji Triage en az doldurulmamış alan oranını gösterdi (p<0.05). Fuji VII EP, Fuji Triage
ve GCP Glass Seal kıyaslandığında en yüksek bağlanma dayanımı Fuji VII EP ile elde edilirken (p<0.05), test
edilen materyaller arasında Ca/P değerleri açısından istatistiksel olarak anlamlı bir fark bulunmadı (p>0.05).
Oluşturulan başlangıç çürüklerine materyallerin uygulanması sonrasında, minedeki flor içeriğinin istatistiksel
olarak artmış olduğu tespit edildi (p < 0.05).
Sonuç: Fuji VII EP ve Fuji Triage materyalleri çalışmada yer alan fiziksel kıyaslamalar açısından başarılı
bulunmuştur. Çalışmada kullanılan tüm fissür örtücü materyaller çürük engelleyici potansiyele sahip görünmektedir.

Amaç; Başarılı bir kanal tedavisi için en önemli aşama kök kanal çalışma boyutunun doğru bir şekilde tespitidir. Bu özellikle alttaki daimi diş jermine verilebilecek zararın minimalize edilmesi açısından da önem taşır.
Süt dişlerinde çalışma boyutu tespiti için birçok farklı yöntem bulunmaktadır. Bu çalışmanın amacı süt dişlerinde çalışma boyutu tespitinde 2 farklı apeks bulucu, el hassasiyeti ve radyografik yöntemlerin karşılaştırmalı
olarak değerlendirilmesidir.
Gereç ve Yöntem; Bu çalışma 5-8 yaş aralığında olan, herhangi bir dental anksiyeteye sahip olmayan ve sistemik olarak sağlıklı 12 çocuğun 15 adet süt molar dişi üzerinde yürütülmüştür. Çalışma, pulpektomi endikasyonu konulmuş dişler üzerinde gerçekleştirilmiş olup, geniş periapikal radyolusensi olan, fistül formasyonu
görülen, mobil (2 den yüksek), restorasyonlu, kalsifiye kanallı ve inflamatuar rezorpsiyonu olan dişler çalışma
dışı bırakılmıştır. Dişler izole edilerek kavite preperasyonu yapıldıktan sonra,pulpa trinerf yardımı ile ekstirpe
edilerek % 5 lik sodyum hipoklorit ve serum fizyolojik ile irrige edilen kök kanalları paper point yardımı ile
kurutulmuştur. Silikon stoperli K-file, el hassasiyeti ile tahmini apekse pasif olarak yerleştirilip ölçümler kaydedilerek dijital radyografi alınmıştır. Alınan radyograf üzerinden yeni ölçümler yapılarak kaydedilmiştir. Son
olarak da elektronik apeks bulucular kullanılarak ölçümler yapılmış olup tüm ölçümler istatistiksel analizler
ile kıyaslanarak ideal apeks belirleme yöntemi bulunmaya çalışılmıştır.
Sonuçlar; Yapılan analizlerle 4 farklı kök kanal boyu tespit yöntemi değerlendirilmesi sonucu el hassasiyetinin radyografi ve elektronik tespit cihazlarına göre daha az doğruluk oranına sahip olduğu görülmüştür. Bununla birlikte
süt dişlerinde çalışma boyutunun radyografik değerlendirilmesinde; kök kanal sistemindeki çeşitli varyasyonlar,
ölçümlerdeki teknik hatalar, zayıf hasta uyumu, taşkın enstrümantasyon riski, kısıtlı ağız açıklığı ve rezorpsiyonun
farklı aşamaları gibi pek çok faktör kanal boyunun doğru şekilde belirlenmesi üzerinde etki edebilmektedir.Bütün bu sebeplerden, birçok çalışma süt dişlerinde kök kanal boyutunun tespitinde yeni yöntemlere odaklanmıştır.

Amaç: Bu çalışmanın amacı; gastroözefageal reflü hastalığı (GÖRH) tanısı konan çocuk hastalarda dental
erozyonun görülme sıklığının belirlenmesi ve erozyona neden olabilecek faktörlerin incelenmesidir.
Metod: Çalışmaya, Ankara Çocuk Sağlığı ve Hastalıkları Hematoloji ve Onkoloji Eğitim ve Araştırma Hastanesi Gastroenteroloji kliniğinde GÖRH tanısı konmuş olan 6-12 yaş arası (ort. 9,9) 64 çocuk dahil edilmiştir.
Ebeveynlere hastalar için kapsamlı bir anket uygulanmıştır. Anket; diğer sistemik hastalık varlığı, GÖRH tanı
süresi, düzenli ilaç kullanımı, diş fırçalama sıklığı ve şekli, içecek ve meyve tüketimi hakkında kapsamlı sorular içermektedir. Klinik muayene sonucunda dental erozyon olduğu saptanan hastalarda erozyondan etkilenen
bölge ve bu bölgedeki yüzey alanı ile görülen erozyonun şiddeti -O-Sullivan diş yıkım indeksi- kullanılarak
değerlendirilmiştir. Elde edilen verilerin istatistiksel değerlendirmesinde Mann Whitney U ve Ki-Kare testleri
kullanılmıştır.
Bulgular: Hastalarda erozyon görülme sıklığı %53 (n=34) olarak bulunmuştur. GÖRH tanısı yeni konmuş
olanlarla eskiden tanısı konmuş ve tedavi görenler arasında erozyon görülme sıklığı açısından anlamlı fark
tespit edilmemiştir (p>0,05). En çok etkilenen dişlerin üst santral ve lateral kesici dişler ve en çok etkilenen
diş yüzeyinin insizal ve lingual yüzeyler olduğu görülmüştür (p<0,05).Hastaların asitli gıdaları tüketme ve
diş fırçalama alışkanlıklarıyla erozyon arasında istatistiksel olarak anlamlı bir ilişki bulunamamıştır (p>0,05).
Bununla birlikte hastalarda yaşla birlikte erozyon görülme sıklığının arttığı ve su tüketiminin artışına bağlı
olarak erozyonun azaldığı görülmüştür (p<0,05).
Sonuç: GÖRH bulunan çocuklarda dental erozyon prevalansının yüksek olması, dişlerdeki aşırı madde kayıplarının önlenmesi için gerekli dental tedavilerin erken dönemde başlamasının gerekliliğini göstermektedir.

AMAÇ: Süpernümerer (artı) dişler, normal dentisyona ilave olarak fazladan sürmüş ya da gömülü kalmış diş
veya diş benzeri yapılardır. Özellikle çocuklarda, gömülü kalmış süpernümerer dişler daimi dişlerin sürmesine engel olarak çapraşıklığa ve estetik sorunlara neden olabilmektedirler. Bu çalışmanın amacı; panoramik
radyografide tespit edilen gömülü süpernümerer dişlerin radyolojik özelliklerinin ve olası patolojilerle ilişkilerinin CBCT ile incelenmesidir.
METOD: Bu retrospektif çalışmada, gömülü süpernümerer diş tespit edilen 27 hastadan elde edilen CBCT görüntüleri incelenerek, süpernümerer dişlerin sayısı, lokalizasyonu, pozisyonu, tipi ve biçimi belirlendi. Ayrıca
bu dişlerle ilişkili patolojiler ve uygulanan tedavi değerlendirildi.
BULGULAR: 27 hastada toplam 29 gömülü süpernümerer diş tespit edildi. Bu dişlerden 9 adedi odontoma
benzeri görüntüye sahipti. Dişlerin daha çok maksillada lokalize olduğu görüldü. Bütün süpernümerer dişler
cerrahi olarak çıkartıldı.
SONUÇ: Süpernümerer dişler komşu dişlerde sürme bozukluğu, çürük, kök rezorpsiyonu, çene kisti oluşması gibi komplikasyonlara yol açabilmektedirler. Bu nedenle, dikkatli klinik ve radyolojik inceleme ile teşhis edilmeleri, olası patoloji ve komplikasyonların önlenebilmesi açısından önemlidir.

Giriş: Farklı kanal konfigürasyonlarının ve kök varyasyonlarının bilinmemesi sebebiyle gözden kaçırılan veya
eksik doldurulan kanalların varlığı kanal tedavisinde başarısızlığa neden olan önemli faktörlerdendir. Endodontide kullanımı yaygınlaşmaya başlayan konik ışınlı bilgisayarlı tomografi (KIBT) görüntüleme tekniği ile
geleneksel intraoral radyografilerin neden olduğu kısıtlamalar ortadan kaldırarak, kök kanal sisteminin morfolojisi ayrıntılı bir biçimde belirlenmekte ve endodontik tedavinin başarı şansı arttırılmaktadır. Yapılan anatomik çalışmalarda genellikle tek köklü ve tek kanallı olarak bildirilen üst keser dişler, endodontik tedavinin
gerçekleştirilmesi açısından kolay olarak düşünülse de literatürde birden fazla kanal veya köke sahip olan üst
anterior dişin olduğu vakalar rapor edilmiştir. Bu vaka raporunda ise; iki ayrı kökü olan üst santral ve lateral
dişin endodontik ve restoratif tedavisi bildirilmektedir.
Vaka Raporu: 12 yaşındaki kız hasta sol üst santral ve lateral dişinin hipoplastik kuronlarının görünümü şikâyetiyle Kocaeli Üniversitesi Diş Hekimliği Fakültesi Pedodonti Ana Bilim Dalı Kliniği’ne başvurmuştur. Yapılan radyolojik muayenede 21 ve 22 numaralı dişlerinin iki köke sahip olduğu ve köklerde lamina duranın
genişlediği tespit edilmiştir. Dişlerin vitalometrik muayeneye negatif cevap vermesi ve perküsyona hassasiyet
göstermesi nedeniyle kök kanal tedavisi yapılması planlanmıştır. KIBT görüntüleri ile santral dişin mesial ve
distal iki köke sahip olduğu lateral dişin köklerinin ise bukkal ve palatinal olarak konumlandığı belirlenmiştir.
Dişler asemptomatik hale gelene kadar kök kanalları kalsiyum hidroksitle pansuman yapılmıştır. Kök kanalları guta perka ile lateral kondansayon tekniği ile doldurulduktan sonra obturasyon kalitesi periapikal radyografi
ile doğrulanmıştır. Hipoplastik ve amorf şekilli olan kuronlar fiber post uygulamasını takiben protetik olarak
restore edilmiştir.
Sonuç: Yapılan periyodik muayeneler sonucunda hastanın hiçbir şikayeti olmadığı ve estetik açısından memnun olduğu gözlenmiştir.

AŞIRI KRON HARABİYETİ NEDENİYLE İNFRA-OKLUZYONDA OLAN PREMOLAR DİŞİN
KISA SÜRELİ ORTODONTİK EKSTRÜZYONU
Gamze TOPÇUOĞLU, Erciyes Üniversitesi - Pedodonti,
Kenan CANTEKIN, Erciyes Üniversitesi - Pedodonti,
Hüseyin Sinan TOPÇUOĞLU, Erciyes Üniversitesi - Endodonti,
Giriş : Travma ve çürük sebebiyle dişlerde kron harabiyeti oluşmaktadır. Bu etmenler neticesinde gingiva seviyesinin altına inen sağlam diş dokusuyla kalan dişin restorasyonunu tamamlamak, izolasyondaki zorluklar
sebebiyle oldukça güçtür. Okluzyon seviyesinin altına düşmüş dişlerde kısa süreli ortodontik tedaviyle dişin
ektrüzyonunu ve dolayısıyla ideal bir final restorasyonunu elde etmek mümkündür. Bu vakada, derin dentin
çürüğünün kaldırılmasının ardından infra-okluzyonda kalan premolar dişin ortodontik bir apereyle kısa süreli
tedavisi ve final restorasyonu sunulmuştur.
Vaka raporu : 15 yaşındaki bayan hasta kliniğimize ağrı şikayeti ile başvurmuştur. Yapılan klinik ve radyografik muayene sonrasında 45 numaralı dişinde pulpa odasına ilerlemiş derin dentin çürüğü tespit edildi. İlgili
dişin çürüğü temizlenerek aynı seansta kanal tedavisi yapıldı. Distal yüzeyinde aşırı madde kaybı olan dişte
yeterli izolasyon sağlanamadığı için dişin ekstrüze edilmesine karar verildi. Ortodonti bölümüyle yapılan konsültasyon sonucunda hasta için bir ortodontik aparey yapılması planlandı. Hastaya bir hafta sonrasına randevu
verildi ve o seansta kanal tedavisi yapılmış dişe post yerleştirilip aparey için ölçüsü alınarak randevu verildi.
İnfra-okluzyonda kalmış dişin ekstrüzyonu için hazırlanan 45 numaralı diş bölgesine gelecek şekilde planlanmış ve üst premolar bölgesinin bukkal sulkusuna uzanan heliks bir büküm içeren ortodontik tele (0,7mm)
sahip olan hawley benzeri bir aparey yapıldı. Ortodontik kuvvetin uygulanabilmesi için 45 numaralı dişin
bukkal yüzeyine bir buton yerleştirildi. Ortalama 150 gr’lık kuvvet uygulayan ortodontik bir elastik, apareyin
45 numaralı diş bölgesindeki helikse ve butona geçirildi. Hastaya apareyin kullanımı öğretildi ve her akşam
lastiğini yenilemesi belirtildi. Üç hafta sonra dişin 3 mm ekstrüze olduğu saptandı ve kontrol radyografisi
alındı. Yeterli okluzal seviyeye gelen dişin preparasyonu yapılarak final restorasyonu full kron ile tamamlandı.
Sonuç: Aşırı kron harabiyetlerinde planlanan basit bir hareketli aparey ile hem tedavi süresi kısaltılabilir hem
de ideal okluzyona gelen dişlere daha başarılı restorasyonlar uygulanabilir.

Giriş: Üst yan kesici dişler genellikle tek kök ve tek kanala sahiptirler. Bununla birlikte, anormal kök kanal
morfolojisine sahip olan üst yan kesici dişler de sıklıkla rapor edilmektedir. Bu dişler genellikle embriyolojik
riskin yüksek olduğu bölgede lokalize oldukları için; geminasyon, füzyon, konkresens yada dens invaginatus
gibi biçim anomalileri sergileyebilmektedirler. Özellikle, Türk toplumunda, üst yan kesici dişlerde, çeşitli
kanal konfigürasyonlarına rastlanıldığı bildirilmektedir. Amaç: Bu olgu sunumu,iki kanallı üst sol yan kesici
dişin dens invaginatus tip III’den ayırıcı tanısının CBCT ile yapılmasını veanatomik varyasyon gösteren kök
kanal sisteminin endodontik tedavisini ve onun estetik rehabilitasyonunu anlatmaktadır.
Olgu Sunumu: 14 yaşında sistemik hastalığı olmayan bir erkek hasta, ekstraoral akut abse nedeniyle amoksisilin reçete edildikten sonra İstanbul Üniversitesi Diş Hekimliği Fakültesi Pedodonti AD.’na yönlendirilmiştir.
Alınan anamnezde, hastanın 3 yaşında sol üst süt yan kesici dişinin travma sonucu intrüze olduğu saptanmıştır.
Klinik değerlendirme sonucu, akut absenin, hipoplazik sol üst sürekli yan kesici dişinden kaynaklandığı belirlenmiş, yapılan elektriksel ve termal vitalite testlerine negatif cevap alınmıştır. Palpasyon ve perküsyona duyarlılık saptanmıştır. Alınan dijital periapikal radyografide dişin dens invaginatus tip III görüntüsüyle uyumlu
olduğu düşünülmüş, kesin tanı koymak amacıyla alınan dental volumetrik tomografide (CBCT) dişin iki kök
ve kanallı bir yan kesici diş olduğu belirlenmiştir. Endodontik tedavisi tamamlanan dişin estetik restorasyonu
kompozit ile yapılmıştır. Olgunun, 6 aylık kontrolünde klinik ve radyolojik olarak herhangi bir patolojiye
rastlanmamıştır.
Sonuç: Bu olgu sunumunda, iki kanallı olan üst sol yan kesici dişin başarılı kanal tedavisi ve dens invaginatus
tip III ile olan ayırıcı tanısı anlatılmıştır. Bu tip olgularda anomalilerin doğru tespit edilmesi, doğru tedavi
planı ve iyi prognoz için önemlidir. Bu amaçla, dental volumetrik tomografiler detaylı radyografik görünüm
elde edilmesi için kullanılabilir.

hastanın üst süt ön dişlerinde ağrı şikayeti vardı. Hastanın annesi çocuğun 1 yıl anne sütü aldığını daha sonra
2 yıl boyunca biberonla şekerli süt içtiğini bildirdi. Çocuk uykuya biberon ağzındayken dalıyordu. İntraoral
muayenede çocuğun süt dişlenmesinin tamamlandığı görüldü. 51, 52, 61, 62 nolu dişlerin çürük oldukları
tespit edildi. İntraoral periapikal radyografide 61 nolu dişteki çürüğün pulpayı içine aldığı belirlendi. 61 nolu
dişe yapılan kök kanal tedavisinden sonra polietilen fiber Ribbond (Ribbond, Seattle, WA, USA) ile kısa post
uygulaması yapıldı. 61 nolu diş stip kronla restore edildi. Diğer süt kesici dişlerdeki çürükler temizlendikten
sonra kompomer uygulandı.
Sonuç: Koronal diş yapısında çok kayıp olduğunda endodontik tedaviden sonra kanal içine uygulanan postlar,
yeniden şekillendirilecek olan krona stabilite ve çiğneme kuvvetlerine karşı güç sağlamaktadır. Bu vakada
da geniş kompozit restorasyondan önce yapılan polietilen fiber post pulpa tedavisi sonrası süt ön kesici dişte
mükemmel klinik performans göstermiştir.

TEK KÖKLÜ VE TEK KANALLI ALT SÜT 1. MOLAR DİŞLERİN ENDODONTİK TEDAVİSİ:
VAKA RAPORU
Neslihan ÖZVEREN, Bezmialem Vakıf Universitesi - Pedodonti Anabilim Dalı,
Şerife ÖZALP, Bezmialem Vakıf Universitesi - Pedodonti Anabilim Dalı,
Giriş: Başarılı bir endodontik tedavi için kök kanal anatomilerinin ve kanal morfolojilerindeki farklılığın
bilinmesi gerekir. Genellikle alt 1. süt molar dişler 2 kök ve 3 kanala sahiptir. Literatürlere göre epitelyal kök
kının invajinasyonundaki hata sonucu oluşan, morfoloji farklılığını gözlemlediğimiz bu vakanın amacı, tek
kök ve tek kanallı alt çene süt 1. molar dişlerin endodontik tedavisi sırasında dikkatli klinik ve radyografik
gözlemin önemini belirtmektir.
Vaka raporu: Diş çürüklerinin tedavi edilmesi amacıyla Bezmialem Üniversitesi diş kliniğine ailesi ile başvuran 8 yaşındaki kız hastanın sistemik olarak herhangi bir rahatsızlığı bulunmadığı saptandı. Muayene esnasında derin dentin çürüğü görülen alt çene sağ ve sol süt 1. molar dişlerin tek köke sahip olduğu gözlemlendi. Ağrı şikayeti ve perküsyonu olmayan dişlerin pulpaya ulaşan dentin çürükleri olması nedeniyle kanal
tedavilerine başlandı. Lokal anestezi altında (Ultracaine DS Ampül, Aventis Pharma San. ve Ltd. İstanbul/
TÜRKİYE) sol alt 1. süt molar dişin endodontik kavitesi açıldı. Pulpa ekstirpe edilip çalışma boy tespiti için
aletli radyografik film alındı. Çalışma boyu hesaplandıktan sonra step-back tekniği ile MAF:30a kadar kanal
genişletildi. Her eğe değişimde kanal %2.5’lik sodyum hipoklorit solüsyonu ile irrige edildi. Steril paper point
ile kurutulan kanal Metapex (Meta Biomed Co. Ltd., Chungbuk) ile dolduruldu. Kavite tabanına çinko fosfat
kaide olarak yerleştirdikten sonra üzeri rezin içerikli cam iyonomer ile kapatıldı. Self-etch bond (Prime&Bond
NT Dentsply, USA) ve kompomer (Dyract XP, Dentsply, USA) kullanılarak dolgusu yapıldı. Aynı işlem bir
sonraki seansta sağ alt 1. süt molar diş için uygulandı.
Sonuç: Günümüze dek tek kök ve tek kanallı alt süt 1. molar dişler ile ilgili çok az sayıda vaka bildirilmiştir. Sadece
klinik gözlem ve anamneze dayanarak bu tür anomali bir dişin tedavisi sırasında fazla kanamanın görülmesi
perforasyon ile karıştırılmasına ve komplikasyonlara neden olabilir. Bu nedenle anormal kök morfolojisine sahip
süt dişlerinde ancak doğru endikasyon ve iyi bir radyografik muayene ile başarılı bir endodontik tedavi yapılabilir.

Amaç: Süt dişi amputasyon tedavilerinde, Kalsiyum Hidroksit (CH) ve Mineral Trioksit Agregat (MTA) materyallerinin kullanımı öncesinde, % 5’lik sodyum hipoklorit (NaOCl) uygulamasının tedavinin başarısına
olan etkilerinin 24 aylık klinik ve radyografik sonuçlarının değerlendirilmesi amaçlanmıştır.
Materyal-Metod: Toplam 128 diş CH ve MTA amputasyonu yapılmak üzere 2 ana gruba, bunu takiben de amputasyon materyalinin uygulanması öncesi %5’lik NaOCl ve serum fizyolojik uygulamak üzere ikişer alt gruba ayrılmıştır. Olgular klinik ve radyolojik olarak 24 ay takip edilmiştir. Gruplar arasında klinik başarı yönünden farkın önemliliği Pearson’un Ki-Kare veya Fisher’s Exact test ile incelendi. Tip I hatayı kontrol edebilmek
için Bonferroni Düzeltmesi yapıldı. Bonferroni Düzeltmesine göre p<0,042 için sonuçlar istatistiksel olarak
anlamlı kabul edildi. Bulgular: Klinik ve radyografik başarı oranları CH- NaOCl alt grubunda % 35.2, CH- salin alt grubunda % 35, MTA- NaOCl alt grubunda %87.5, MTA- salin alt grubunda %100 olarak belirlenmiştir.
CH ve MTA gruplarında alt gruplar arasındaki farkın istatistiksel olarak anlamlı olmadığı ancak MTA- NaOCl
grubunun CH-NaOCl grubuna göre 24. ayda istatistiksel olarak anlamlı derecede (p<0.002) daha başarılı olduğu belirlenmiştir. MTA- serum grubunun ise hem 18.ayda (p<0.001) hem de 24. ayda (p<0.001) CH-serum
grubuna göre istatistiksel olarak anlamlı derecede daha başarılı olduğu belirlenmiştir.
Sonuç: 24 aylık takip süreci sonunda NaOCl uygulamasının CH amputasyonlarında kontrol grubuna göre
başarı açısından istatistiksel olarak anlamlı farklılık yaratmadığı ancak uzun dönem takipte CH amputasyonlarının başarı yüzdesinin her iki alt grupta da belirgin bir farklılıkla düşüş gösterdiği belirlenmiştir. MTA
amputasyonunda ise NaOCl uygulamasının alt gruplar arasında istatistiksel olarak anlamlı farklılık yaratmadığı ancak NaOCl uygulaması açısından CH ve MTA grupları birbirleriyle karşılaştırıldıklarında MTA gruplarındaki başarının CH’ye göre 24. ayda istatistiksel olarak anlamlı bir farkla yüksek olduğu belirlenmiştir.

Amaç: Sodyum hipoklorit (NaOCl), antibakteriyel olması ve doku çözücü etkisi nedeniyle süt dişi vital pulpa
tedavilerinde amputasyon medikamanı olarak kullanımı tercih edilen bir materyaldir. Bu çalışmada, Kalsiyum
Hidroksit (CH) ve Mineral Trioksit Agregat (MTA) amputasyonlarında %5’lik NaOCl uygulamasının, süt dişi
pulpasının histopatolojik cevabına etkisinin değerlendirilmesi amaçlanmıştır.
Materyal-Metod: Toplam 128 süt azı dişi MTA ve CH olmak üzere 2 ana gruba ve bu gruplar da kendi içlerinde
NaOCl (deney grubu) ve serum fizyolojik (kontrol grubu) olarak 2 alt gruba ayrılmıştır. 24 aylık takip süresi
sonunda altındaki daimi dişin yeterli kök gelişiminin tamamlandığı belirlenen 36 diş histolojik inceleme için
çekilmiştir. CH- NaOCl grubunda 3, CH- serum grubunda 5, MTA- NaOCl grubunda 5, MTA- serum grubunda 7 örnek olmak üzere toplam 20 dişin histolojik inceleme için uygun kesitlere sahip olduğu belirlenmiştir.
Örnekler; pulpal enflamasyon varlığı ve şiddeti, sert doku köprü devamlılığı ve tübüler yapısı, odontoblastik
tabaka devamlılığı ve iç rezorpsiyon kriterlerine göre incelenmiştir. Gruplar arasında klinik bulgular yönünden farkın önemliliği Mann Whitney U veya Fisher’s Exact test ile incelendi. Tip I hatayı kontrol edebilmek
için Bonferroni Düzeltmesi yapıldı. Bonferroni Düzeltmesine göre p<0,025 için sonuçlar istatistiksel olarak
anlamlı kabul edildi.
Bulgular: CH veya MTA gruplarının her ikisinde de, deney ve kontrol grupları arasında test edilen kriterlerin gözlenme oranlarında istatistiksel olarak anlamlı bir farklılık belirlenmemiştir (p>0.025). MTA- NaOCl
grubunda; sert doku köprü devamlılığı, pulpal enflamasyon ve odontoblastik tabaka devamlılığı kriterlerinin
gözlenme oranının, CH-NaOCl grubuna göre anlamlı derecede yüksek olduğu belirlenmiştir.
Sonuç: CH veya MTA amputasyonlarında, dezenfektan medikaman olarak NaOCl uygulamasının, serum uygulanan gruplara göre başarı kriterlerinin gözlenme oralarında istatistiksel olarak anlamlı bir farklılık yaratmadığı belirlenmiştir. Kullanılan yöntemden bağımsız olarak MTA’nın CH’ye göre üstün bir materyal olduğu,
vital amputasyon tedavilerinde uygun materyal seçiminin, pulpa odasında uygulanan medikaman seçminden
daha önemli olduğu belirlenmiştir.

Giriş: İntrüzyon yaralanmaları genellikle 6-12 yaş arasındaki çocuklarda görülen ve dişin alvaeol kemiği içerisinde apikal yönde yer değiştirmesine yol açan en sert travmatik yaralanmalardan biridir. Bu tip yaralanmaların
sonucunda, pulpa vasküler desteğini kaybetmekte ve periodontal ligament sert bir biçimde yaralanmaktadır.
Klinik olarak diş kısalmış görülür, hatta ciddi olgularda diş tamamen ortadan kaybolabilir. İntrüziv lüksasyonun tedavisi ve prognozu hastanın yaşı, kök gelişimi ve travmanın şiddetine bağlı olarak değişebilmektedir.
Olgu: Daimi sağ üst santral dişi alveol kemik içerisine tamamen gömülmüş olan 9 yaşındaki erkek hastada,
travma üzerinden 24 saat geçmiş halde kliniğimize başvurdu. Bukkal mukozada şişlik ile beraber maksillar
sağ santralın tamamen intruze olduğu görüldü. Kökün apikal gelişimi ve intrüzyonun şiddetine bağlı olarak,
dişin acilen cerrahi olarak yeniden konumlandırılması ve kök kanal tedavisi yapılması planlandı. Cerrahi olarak ekstrüze edilen diş 4 hafta süreyle semirijit olarak splintlendi. Repozisyonu takip eden 5 gün boyunca antibiyotik terapisi uygulandı. Repozisyondan sonra pulpa ekstirpasyonu ve kök kanal tedavisi gerçekleştirildi.
Diş kompozit rezin ile restore edildi. Hasta 6 ayda bir kontrol muayenelerine çağrıldı.
Sonuç: 18 ay sonraki klinik ve radyolojik incelemelerden sonra apikal bölge ve destek dokularda sağlıklı iyileşme olduğu görülmüştür.

Giriş: Travmatik diş yaralanmaları özellikle 8-11 yaş çocuk hastalarda sık karşılaşılan bir halk sağlığı sorunu
olsa da horizontal kök kırıkları diğer travmatik yaralanmalara göre daha nadir görülen vakalardır. Travma
sonucu oluşan horizontal kök kırıklarının apikal üçlüde olması durumunda prognozun genellikle iyi olduğu
bildirilmektedir. Radiküler kist, pulpası nekroze olan dişlerin periapikal bölgesinde gelişen ve enflamasyona
bağlı ola-rak oluştuğu düşünülen, kronik enflamatuar bir kist olup odontojenik kistler içinde en yaygın görülen
kisttir. Bu vaka raporunda horizontal kök kırığı sonrası oluşan radiküler kiste ait teşhis ve tedavi prosedürü
sunulmaktadır.
Vaka raporu: 14 yaşındaki erkek hasta damak bölgesindeki şişlik nedeniyle Kırıkkale Üniversitesi Diş Hekimliği Fa-kültesi Pedodonti AD kliniğine başvurmuştur. Hastanın ağız içi muayenesinde 11-12-13 nolu dişler
hizasında palatinal bölgede şişlik görülmüş, ilgili bölgeden alınan periapikal ve panoramik radyografi-lerde,
geçmişte horizontal kök kırığı oluştuğu tahmin edilen 12 no’lu dişten kaynaklanan geniş bir kistik lezyon ve
bu lezyonla ilişkili deplase olmuş apikal fragman gözlenmiştir. Hastadan alınan anamnezde birkaç yıl önce
dental yaralanma geçirdiği ancak tedavi görmediği öğrenilmiştir. Söz konusu kistik yapı ve diş cerrahi olarak
çıkarılmış, yapılan patolojik inceleme sonucu radiküler kist tanısı konmuştur.

Giriş: Lüksasyon ve avülsiyon özellikle genç sürekli dişlerde sıklıkla karşılaşılan travmalardır ve çocuklarda
olumsuz estetik, fonksiyonel ve psikolojik sorunlara yol açmaktadır. Bu olguda kök gelişimi tamamlanmamış
üst çene kesici dişlerinin travma sonrası tedavisi sunulmuştur.
Olgu: 9 yaşındaki erkek hasta geçirdiği travmadan 1 gün sonra İstanbul Üniversitesi Diş Hekimliği Fakültesi
Pedodonti Anabilim Dalı kliniğine başvurmuştur. Hasta travmadan 2 saat sonra diş hekimine götürülmüş ve
yarı rijid slint uygulanmıştır. Yapılan ağız içi muayenesi sonucu, splintte kopma meydana geldiği, 12 no’lu
dişin avülse olduğu, 11 ve 21 no’lu dişlerde ise lüksasyon saptanmıştır. 12 no’lu diş kaza sonrası bulunamadığından reimplantasyon gerçekleştirilememiştir. 11 ve 21 no’lu dişlerde vitalite testlerine negatif yanıt alınmış,
radyografik muayene sonucu dişlerin gelişimlerinin tamamlanmamış olduğu saptanmıştır. Eski splint çıkartılarak tekrar yarı rijid bir splint 3 hafta süre ile uygulanmıştır. Travmaya uğrayan dişlerde 6 ay süresince vitalite
testlerine negatif yanıt alınmış, patolojik lüksasyon ve fistül oluşumu görülmemesi nedeniyle yalnızca takip
edilmesine karar verilmiştir. 1 yıllık takip sonucunda vitalite testlerine pozitif yanıt alınmış, 2 yıllık takip sonucunda klinik ve radyografik olarak dişlerin sağlıklı olduğu ve kök gelişimlerinin devam ettiği gözlenmiştir.
Sonuç: Travmaya uğramış, kök gelişimi tamamlanmamış genç sürekli dişlerde revaskülarizasyon sonucu pulpanın iyileşmesi görülebilir. Bu tür olgularda uzun süreli klinik kontroller iyileşme sürecini izlemek veya
gelişebilecek komplikasyonları saptamak açısından gereklidir.

Oya AKTÖREN, Dişhekimliği FAkültesi - Pedodonti Anabilim Dalı,
Giriş: İntrüzyon travmaya bağlı olarak dişin alveol kemiği içerisinde yer değiştirmesidir. Periodontal ligament, damar-sinir paketi ve alveol kemiği gibi yapıların aynı anda zarara uğramasından dolayı prognozu en
şüpheli dental travma tiplerinden biridir. Daimi dişler için uygulanabilecek tedavi seçenekleri dişin kendiliğinden sürmesinin beklenmesi, cerrahi repozisyon ve ortodontik ekstrüzyondur. Bu olgu sunumunda travmaya
bağlı olarak üst orta kesici dişte intrüzyon ve komplike kuron kırığı bulunan çocuk hastada uygulanan tedavi
yaklaşımı sunulmuştur.
Olgu: 10 yaşındaki erkek hasta İstanbul Üniversitesi Diş Hekimliği Fakültesi Pedodonti Anabilim Dalı’na
bisiklet kazası hikayesi ile başvurmuştur. Klinik muayenede 11 numaralı dişin kuronunun labiale doğru yer
değiştirerek intrüze olduğu ve komplike kuron kırığı bulunduğu belirlenmiştir. Periapikal radyografide ilgili
dişin apeksinin açık olduğu ve alveolar soket kırığı gözlenmiştir. Tedavide 11 numaralı dişin ortodontik ekstrüzyonu ve kalsiyum hidroksit ile apeksifikasyonu planlanmıştır. 13 aylık sabit ortodontik tedavi sonrası ideal
oklüzyon sağlanmış ve 11 numaralı dişin kök oluşumunu takiben endodontik tedavisi tamamlanarak kuron
harabiyeti kompozit rezin ile restore edilmiştir. 1 yıllık kontrollerde klinik ve radyografik olarak herhangi patolojik bulguya rastlanmamıştır.
Sonuç: Bu olguda intrüzyon derecesinin fazla oluşu ve alveol soket kırığı varlığı göz önünde bulundurularak
tedavide hafif kuvvetler ile ortodontik ekstrüzyon tercih edilmiştir.

Kenan CANTEKIN, Erciyes Üniversitesi Diş Hekimliği Fakültesi - Pedodonti Ana Bilim Dalı,
Giriş: Daimi dişlerdeki lüksasyon yaralanmaları sublüksasyon, lateral lüksasyon, intrüzyon ve ekstrüzyon olarak sınıflandırılmaktadır. Ekstrüzyonun klinik belirtisi dişin uzaması ve mobil olmasıdır. Radyografik olarak
apikal bölgede artmış periodontal aralıktır gözlenir. Tedavisi ekstrüze olan dişi olabildiğince erken dönemde
repoze etmek ve iki hafta esnek bir splint ile stabilize etmektir. Ancak tedavinin zamanında yapılamamış
olması nedeniyle diş repoze edilemeyebilir, böyle durumlarda dişi repoze edebilmek için farklı yöntemlere
başvurulabilir. Bu yöntemlerden biri kasti replantasyon tedavisidir. Kasti replantasyon yakın geçmişte en son
çare olarak düşünülmesine rağmen, son yıllarda periodonsiyum ile ilgili bilgilerin ve geliştirilmiş tekniklerin
artması ile artık son çare olarak görülmemektedir.
Olgu Sunumu: Alınan anamnez sonucunda, 11 yaşında erkek hastanın okulda geçirdiği bir kaza sonucunda
11 numaralı dişinde ekstrüzyon meydana geldiği, kaza sonrası bulunduğu şehirdeki bir diş hekimi tarafından
ilgili dişe splint uygulandığı ve kazadan 25 gün sonra splintin çıkmasına bağlı olarak dişindeki mobilite nedeniyle Erciyes Üniversitesi Diş Hekimliği Fakültesi Çocuk Diş Hekimliği Kliniğine başvurduğu öğrenilmiştir.
Travma üzerinden uzun zaman geçmesi nedeni ile diş repoze edilememiştir. Bu nedenle cerrahi bir işlem olan
kasti replantasyon tedavisi uygulamaya karar verilmiştir. Diş çekilmiş, kanal tedavisi yapılmış, çekim soketi
ılık serum fizyolojik ile irrige edilip kan pıhtısı uzaklaştırılmıştır. Kanal tedavisi yapılmış olan diş replante ve
repoze edilmiş, 3 hafta süre ile yarı rijit splintleme yapılmıştır. Hasta düzenli haftalık ve 2 haftalık kontrollere
çağırılmış 4 haftada bir radyografik değerlendirme yapılmıştır. İkinci ay sonrasında apikal bölgede eksternal
rezorbsiyon başladığı gözlenmiştir. Bunun üzerine dişe apikal rezeksiyon yapılmış ve rezeksiyon sonrasında
yapılan 3 aylık kontrollerle toplam 21 aylık takipte rezorbsiyonun engellendiği görülmüştür.
Sonuç: Ektrüsiv lüksasyon tedavisinde, travmadan sonra olabildiğince erken dönemde repozisyonlandırma
ve splint ile stabilizasyon önemli yer almaktadır. Bütün travmatik yaralanmalar da olduğu gibi bu travmaların tedavisinde de zaman önemli bir faktördür. Ancak travma sonrasında aradan uzun zaman geçtiği durumlarda kasti replantasyon gibi tedavi seçeneklerinin başarılı sonuçlar sağlayabileceği değerlendirilmiştir.
Anahtar Kelimeler: Ekstrüzyon, Kasti Replantasyon, Apikal Rezeksiyon

Giriş: Ön çapraz kapanış estetik ve fonksiyon açısından önemli bir problemdir. Çocuk diş hekimleri ve ortodontistler dental gelişimin erken evresinde ön çapraz kapanışın teşhis ve tedavisinden sorumludurlar. Karışık
dişlenme döneminde ön çapraz kapanışın tedavisi mümkündür ve tedavinin gecikmesi daha komplike durumların oluşumuna neden olabilir.
Amaç: Bu olgu serisinde Ordu Üniversitesi Diş Hekimliği Fakültesi Pedodonti Anabilim Dalı’na başvuran ve
ön çapraz kapanış tespit edilen bir grup çocuk hastanın dental tedavileri sunulacaktır.
Olgu Raporu: Çalışmaya yaşları 9-11 (ortalama 9,57 yaş) arasında değişen, sadece ön bölgede bir veya iki dişi
çapraz kapanışta olan 7 çocuk (3 kız ve 4 erkek) dahil edilmiştir. Tüm hastalar karışık dişlenme döneminde
olup, azı ilişkisi Angle sınıf I’dir. Hastaların sefalometrik ölçümleri yapıldıktan sonra hareketli ortodontik
apareyleri hazırlanmış ve zemberekler aktive edilmiştir. Tüm hastalara diyet önerileri ve apareyin kullanımı
ile ilgili bilgilendirme yapılmıştır. Her aparey 2 hafta sonra kontrol edilmiş, gerek duyulması halinde apareyler yenilenerek 3 ay süresince kontrollere devam edilmiştir. Hastalarda ortalama olarak 8.2 haftada ön çapraz
kapanışın düzenlendiği tespit edilmiştir.
Sonuç:Angle sınıf I azı kapanışına sahip, bir veya iki kesici dişi çapraz kapanışta olan hastalar hareketli ortodontik apareyler ile kısa sürede, düşük maliyette ve ileri ortodontik tedavilere duyulan gereksinim azaltilarak tedavi edilebilir.

Giriş: Ön çapraz kapanış; iskeletsel, dental veya hem iskeletsel hem de dental kaynaklı olabilir. Karışık dişlenme döneminde dental kaynaklı ön çapraz kapanışın tedavisi ile daha komplike olan maloklüzyon oluşumunu önlemek mümkündür. Dentofasiyal gelişimle birlikte gerçek Klas III ilişkisi oluşumunu önlemek için ön
çapraz kapanışın neden olduğu pseudo Klas III diye de ifade edilen bu durumun karışık dişlenme döneminde
ortadan kaldırılması önerilmektedir. Ön çapraz kapanış tedavisi için sabit ortodontik tedavi, zemberekli hareketli aparey, kompozit rezin slop gibi çeşitli tedavi seçenekleri önerilmektedir. Ön çapraz kapanış tedavisinde
hareketli aparey kullanımı; güvenli, kolay uygulanabilen, hasta tarafından kabul edilebilir bir yöntemdir.
Amaç: Bu olgu sunumunda, benzer özellik gösteren 9 hastanın ön çapraz kapanışı zemberekli hareketli aparey
ile tedavi edilmiş, tedavi yönteminin etkinliği ve süresi değerlendirilmiştir.
Olgu Sunumu: Bu olgu serisindeki hastalar; İstanbul Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti A.D.’na
dental muayene için başvuran ön çapraz kapanış anomalisi gösteren çocuklar arasından seçilmiştir. Yaşları
7-12 arasında değişen 9 çocuk tedavi kapsamına alınmıştır. Tedavi için seçilen hastaların; karışık dişlenme döneminde, Angle sınıf I oklüzyonda, ön bölgede bir dişte çapraz kapanış ilişkisinin ve labialde repozisyon için
yeterli mesafesinin olması gibi benzer kapanış özelliklerine sahip olmalarına dikkat edilmiştir. 9 hastanın ön
çapraz kapanış anomalisi hareketli zemberekli aparey ile tedavi edilmiştir. Aparey, azılar bölgesinde oklüzyon
yükseltici plak ve protrüzyon zembereğinden oluşmaktadır. Protrüzyon zemberekleri 3 haftada bir klinikte
hekim tarafından aktive edilmiştir. Ön çapraz kapanışın tamamen düzeldiği ve yeterli overbite ilişkisinin sağlandığı seansta apareylerin kullanımına son verilmiştir.
Sonuç: Hastaların tamamında 3-8 hafta içinde alt kesicilere göre palatinalde yer alan üst kesici dişlerin labiale doğru yöneldiği ve normal overbite ilişkisinin sağlandığı görülmüştür. Vertikal olarak relaps oluşumunu önleyecek
olan gerekli overbite kilit ilişkisi sağlanmıştır. Bu sonuçlar ışığında, hareketli zemberekli apareylerin, Angle sınıf
I oklüzyonda izlenen tek diş ön çapraz kapanış olgularında başarılı bir şekilde kullanılabileceği düşünülmektedir.

Amaç: Araştırmada; 12-14 yaşları arasındaki çocukların kendilerinin farkettikleri diş düzensizlikleri ve buna
bağlı ortodontik tedavi gereksinimlerinin ve bu gereksinimlerin cinsiyet, dişsel malokluzyon, ailenin eğitim
seviyesi ve sosyoekonomik durumu gibi değişkenlere göre değerlendirilmesi amaçlanmıştır. Metot: SDÜ Diş
Hekimliği Fakültesi Pedodonti ABD Kliniği’ne başvuran, 12-14 yaşları arasındaki 420 hasta ortodontik tedavi
ihtiyacı bakımından değerlendirilmiştir. Bu amaçla; hastalara dişlerinin görünümünden memnuniyeti, gerekli
görüldüğü takdirde ortodontik tedavi isteği ve nedeni, ailelerinin sosyoekonomik düzeyleri ve eğitim seviyeleri ile ilgili yukarıdaki parametreler değerlendirilmiştir.
Bulgular: 420 hastanın (238 kız, 182 erkek) 113’ü dişsel olarak Sınıf I, 128’i Sınıf II, 80’i Sınıf II Div 1, 66‘sı
Sınıf II Div 2, 33’ü Sınıf III malokluzyona sahiptir. Çalışma grubunun %71,6’sı dişlerinin görüntüsünden
memnun olmadıklarını belirtmişlerdir. Bu hastaların %79’u, memnuniyetsizliklerinden dolayı daha önce de
diş hekimine başvurduklarını bildirmişlerdir. Gülerken dişlerinden dolayı rahatsızlık duyduğunu söyleyen 192
kişiden (%54,3) sadece 7 kişisi konuşurken her zaman eliyle ağzını kapatmaktadır. Çalışma grubunun %75,9’u
ortodontik tedaviyle dişlerinin düzeltilmesinin gerekli olduğunu belirtmiştir. Neden olarak da, büyük çoğunluğu (%73) dişlerinin güzel gözükmesini istediklerini bildirmişlerdir. Tedavide kullanılacak apareyin hastaların %25,9‘u sabit, %41,9‘u hareketli olmasını isterken, geri kalanı farketmeyeceğini söylemiştir. Çalışma
grubunun %45,7‘si estetiğin, %38,3‘ü fonksiyonun, %16’sı her ikisinin de önemli olduğunu belirtmişlerdir.
Ailelerin sosyoekonomik durumlarına bakıldığında; %56,8’inin düşük, %27,3’ünün orta, %5,2’sinin yüksek,
%10,4’ünün çok yüksek aylık gelir seviyesinde olduğu belirlenmiştir. Ailelerin eğitim seviyeleri incelendiğinde, %41’inin ilkokul,%14’ünün ortaokul, %24’ünün lise, %20’sinin üniversite mezunu olduğu görülmüştür.
Sonuç: Çocukların ortodontik tedavilerinin başarılı olabilmesi için çocukların görüş ve desteği alınmalıdır.
Hastaların birçoğunun Sınıf I kapanışa sahip olduğu, karma dişlenme döneminde hekimlerin problemleri o
dönemde de çözebileceği sonucuna varılmıştır. Ailelerin sosyoekonomik düzeyleri ve eğitim seviyeleri düşük
olsa bile çocukların farkındalıklarının olduğu görülmüştür.

Giriş:Bir dişin normalden büyük olduğu boyut anomalilerine makrodonti denilmektedir. Makrodonti görülme
sıklığı azdır ve en sık üst kesici dişler, ikinci olarak da alt süt azı dişleri etkilenmektedir.
Olgu Raporu: Bu olguda alt çenede çift taraflı makrodonti görünümünde küçük azı dişleri belirgin özellikleri
ile sunulmuştur. 14 yaşında sağlıklı bir erkek hasta sol alt çenesinde şiddetli ve spontan ağrı şikayeti ile kliniğe başvurdu. Yapılan klinik, periapikal ve panoramik radyografi değerlendirme sonrasında hastanın 45 nolu
dişinde pulpayı içine alan derin dentin çürüğü görüldü. İrreversibl pulpitis teşhisi konulan ilgili dişin endodontik tedavi yapılarak ağızda tutulmasına karar verildi ve karmaşık kök kanal anatomisini belirleyebilmek için
konik ışınlı bilgisayarlı tomografi (KIBT) alınması planlandı. Alınan KIBT de dişin mesialde 2 distalde de 1
olmak üzere üç kanalı olup, bu kanalların da yatay pulpa dokusu içeren koridorlarla birbirlerine bağlandığı
gözlendi. Lokal anestezi altında tedavi öncesi restorasyon gerçekleştirildi, lastik örtü uygulamasını takiben
endodontik giriş kavitesi açıldı. Pulpa koridorları ultrasonik uçlarla birleştirildi. Kök kanalları döner alet sistemi ile şekillendirildi ve son olarak akışkan gutta perka ile dolduruldu. Kompozit rezin ile final restorasyon
yapıldı.
Sonuç: Makrodontinin okluzyon ve çürük gelişebilme açısından risk oluşturduğu bilinmektedir. Öte yandan
makrodont dişler özellikle estetik kaygının fonksiyondan daha az önemli olduğu posterior bölgede doğru klinik yaklaşımla başarılı şeklide ağızda tutulabilirler.

Giriş: Besinlerle prohormon şeklinde alınan D vitamini, yağda çözülen, vücutta kalsiyum ve fosfat metabolizmasında rol oynayan bir vitamindir. Diş ve kemik gelişiminde önemli bir role sahip olan D vitamini fazlalığı,
kanda kalsiyum düzeyinin yükselmesine bağlı olarak, kemiklerin daha kırılgan hale gelmesine neden olurken,
dişlerde ise mine hipoplazisi ve pulpa kalsifikasyonlarına neden olabilmektedir. Amaç: Bu olgu sunumunun
amacı; çocukluk döneminde geçirilen D vitamini intoksikasyonuna bağlı olarak, gelişim dönemindeki dişlerde
ortaya çıkan çoklu diş anomalilerinin değerlendirilmesidir.
Vaka Raporu: Diş çürüklerinin tedavi edilmesi için Bezmialem Vakıf Ünivesitesi Pedodonti Kliniği’ne başvuran 8 yaşındaki kız hastanın sistemik olarak herhangi bir hastalığının olmadığı saptandı. Yapılan intraoral
klinik muayenede sürmüş halde bulunan daimi alt ve üst santral kesici ile alt lateral kesici dişlerde kuronal
orta 1/3’te çizgi şeklinde hipoplazik alanlar gözlendi. Üst lateral kesici dişlerde ise insizal 1/3’te hipoplazik
alanlar belirlendi. Alt ve üst birinci molar dişlerin de hipoplazik yapıda olduğu saptandı. Yapılan radyografik
muayenede ise daimi kanin dişlerinin köklerinde dilaserasyon ve kuronlarında morfolojik bozukluk olduğu
gözlendi. Süt dişlerinin ise normal kök ve kuron morfolojisine sahip olduğu tespit edildi. Alınan ayrıntılı
anamnezde, hastaya, 1 yaşında iken yürüyüş bozukluğu nedeniyle D vitamini eksikliği tedavisine başlandığı
ve tedavi sırasında ortaya çıkan bulantı, kusma ve ishal şikayetleri nedeni ile yapılan tetkikler sonucu D vitamini intoksikasyonu teşhisi konulduğu öğrenildi. Tedavi planlamasında öncelikle çürük dişlerin tedavisi, daha
sonra da hipoplazik alanların restorasyonu amaçlandı. İleri derecede madde kaybı olan alt daimi birinci molar
dişler, çürük temizlendikten sonra self-etch bond (Clearfil SE Bond, Kuraray, Japan ) ve kompozit (Clearfil
Majesty ES-2 Kuraray, Japan) kullanılarak restore edildi. Üst ve alt kesici dişlerin ise minimal preparasyon
sonrası kompozit dolgu ile estetik restorasyonları tamamlandı.
Sonuç: Diş gelişiminin matriks formasyonu ve kalsifikasyon aşamaları, hipoplazi ve hipokalsifikasyon gibi
defektlere neden olabilen çeşitli faktörlerin etkisi altındadır. Çocukluk döneminde geçirilen D vitamini intoksikasyonu da bu faktörlerden birisidir.

Giriş: Bu sendrom ilk kez 1988 yılında Toriello Carey tarafında 4 çocuk hastada tanımlanmış otozomal resesif
geçiş gösteren bir sendromdur (OMIM 217980). Sendromun ayırıcı tanısında Pierre Robin ve Opitz sendromları yer almaktadır. Sendromla ilişkilendirilmiş belirgin kranio-dento-fasiyal farlılıklar mikrosefali, geniş fontaneller, hidrosefali, küçük palpebral fissürler, kısa kirpikler, hypertelorizm, telekantus, strabismus, belirgin
kulaklar, burun kanatları açık fakat küçük burun, microstomi, mikroretrognathizm, glossoptosis, yarık damak,
oligodonti, ve maloklüzyondur.
Vaka Raporu: Bu vaka raporunda dental tedaviler için Pedodonti Kliniğine başvuran 8 yaşında kız hastanın
dento-fasiyal özellikleri ile tedavi planlaması anlatılmaktadır. Tanı konulmuş biçimde kliniğe başvuran hasta
55 nolu dişinde spontan ağrı hikayesi bildirmiştir. Panoramik röntgen ile radyolojik değerlendirme ve klinik
muayene sonucunda hastanın 55,65,75 ve 85 Nolu dişlerin aşırı madde kaybı ve periapikal patolojiler nedeni
ile çekim ile tedavilerine karar verilmiştir. Hastada dental problemlerin yanısıra ortodontik olarak maksiller
darlık ve açık-kapanış gözlenmiştir. Yaş ve sendrom nedeniyle hasta ile iletişim kurulamamıştır. Hastanın
dental işlemleri genel anestezi altında tamamlanmıştır. Genel anestezi sırasında ve sonrasında herhangi bir
komplikasyon gelişmemiştir. Hasta işlem sonrasında 3er aylık kontrollere çağırılmıştır. Tek bir kontrole gelen
ve daha sonra başvurmayan hasta 3 sene sonra kliniğimize başvurmuştur. Bu süre içerisinde mandibulada belirgin büyüme gelişmiş ve maksilla küçük kalmıştır. Erken süt dişi kaybı nedeniyle malokluzyonu şiddetlenen
hastaya ortodontik tedavi yapılması planlanmaktadır.
Sonuç: Toriello Carey nadir görülen bir sendrom olup, anamnezde aile hikayesi bulunduğunda morfolojik
ultrason teknikleri ile intaruterin yaşamda tanı konulabilen bu sendroma ilişkin belirgin fasiyal özellikler nedeniyle dişhekimlerinin farkındalığı klinik önem taşımaktadır. Tanısının erken konması, ileride gelişebilecek
klinik problemlerin takibi açısından önem taşımaktadır.

GİRİŞ: Cherubism; non-neoplastik, maksilla ve mandibulada ciddi yıkımlar oluşturabilen, otozomal dominant
geçişli, fibro-osseöz bir anomalidir. İlk kez 1933 yılında Jones tarafından tanımlanmıştır. Sıklıkla erkeklerde
gözlenen bu anomali ilk bulgularını alt yüz bölgesinde, ağrısız, bilateral şişlikler olarak verir. Genellikle hastalarda karakteristik \’melek yüzü\’ görünümü gözlenir. İki-üç yaşlarında başlayan lezyonlar ergenliğin sonlarına doğru spontan regresyon gösterir. Radyografik olarak; maksilla ve mandibulada iyi sınırlı, multioküler,
radyolüsent lezyonlara rastlanılır. Cherubism tedavisinde sıklıkla hastalar puberte dönemi sonuna kadar takip
edilir.
VAKA RAPORU: 5 yaşındaki kız hasta, alt çenesinde çift taraflı şişlik şikayetiyle Kocaeli Üniversitesi Diş
Hekimliği Fakültesi Pedodonti Kliniğine başvurdu. Hastanın ekstraoral muayenesinde yanak bölgesinde bilateral, ağrısız, sert şişlikler ve bilateral ağrısız submandibular lenfadenopati saptandı. Hastanın intraoral muayenesinde alt ve üst süt molar dişlerinde aproksimal çürükler olduğu tespit edildi. Alınan panoramik film ve
KIBT (Konik Işın Huzmeli Bilgisayarlı Tomografi) sonucunda mandibula posteriorunda bilateral, radyolusent, multipl kistik lezyonlar tespit edildi. Cherubism ön tanısı konulan hastada yapılan genetik (SH3BP2)
ve laboratuar testleri cherubism tanısını destekledi. Hastanın gerekli restoratif tedavileri gerçekleştirildikten
sonra hasta takibe alındı.
SONUÇ: Cherubism, karakteristik radyolojik görüntülere sahiptir. Ancak, cherubism tanısında radyografik
değerlendirme tek başına yeterli değildir. İlaveten hastalığın klinik görüntüsü, lokasyonu, tutulumu oldukça
büyük önem taşır. Cherubism tedavisi amacıyla erken yaşta uygulanan gereksiz radikal cerrahi işlemleri engellemek için, çocuk hastaları ilk gören hekimler olarak Pedodontistlerin sistemik hastalıklar ve kraniofasiyal
sendromlar açısından yeterli bilgi ve donanıma sahip olması gerektiği bu vaka ile 1 kez daha vurgulanmaktadır.

Giriş: Dudak-damak yarıkları(DDY), büyüme ve gelişimi etkileyen kompleks problemleri içeren en yaygın
fasiyal deformitelerden biridir. DDY etiyolojisinde, hem genetik hem de çevresel faktörlerin rol oynadığı
ancak bu vakaların büyük bir kısmında multi-faktöryel kalıtımın geçerli olduğu düşünülmektedir. DDY’li
çocuklarda, cerrahi tedavilerden sonra bile, hastalarının rehabilitasyonu özellikle fonksiyonel ve estetik olarak oldukça önem taşır, fasiyal ve oral deformiteler diş hekiminin müdahalesini gerektirir. Doğumla başlayıp
hastanın büyüme gelişiminin bitimine kadar devam eden tedavi sürecinde düzgün bir fonksiyonel yapı kazandırılmasının yanı sıra tatmin edici estetik sonuç, hastanın hayat kalitesinin arttırılması açısından oldukça
önlemlidir. Konjenital damak yarıklı bireylerde en büyük sorunlardan biri de konuşmadır.
Olgu ve Sonuç: Bu olgu sunumunda, diş ağrısı, konuşma ve estetik sorunlar sebebiyle Atatürk Üniversitesi Diş
Hekimliği Fakültesi Pedodonti Anabilim Dalı’na başvuran 6 yaşında çift taraflı dudak-damak yarıklı erkek hastanın genel anestezi altında yapılan restoratif tedavilerini takiben, estetik ve fonetik rehabilitasyon rapor edilmiştir.

Ercan MIHÇI, Akdeniz university of Medical - Pediatric Genetics,
Giriş: Cri-du-chat sendromu (CdCs) 5 nolu kromozomun kısa kolundaki delesyondan kaynaklanan, nadir
görülen bir genetik bozukluktur. Bu sendrom, kedi miyavlaması şeklinde ince, tiz, yüksek sesli ağlama ile
karakterizedir. İnsidans, canlı doğumlarda 1:15000 ile1:50000 arasında değişmektedir. Oral bulgular; mikrognati, malokluzyonlar, yüksek damak ancak nadiren damak yarığı ile birlikte görülür, ön açık kapanış, kötü ağız
hijyeni, mine hipoplazisi, kronik periodontitis, diş sürmesinde gecikme olarak bildirilmiştir.
Olgu Sunumu: Bu olgu raporunda, CdCs teşhisi konulan 2 yaşındaki Türk kızının, tipik tıbbi ve dental bulguları ile dental tedavisi sunulmaktadır. Hasta, kliniğimize kötü ağız hijyeninden kaynaklanan çürük şikayeti ile
gelmiştir. Hastanın yapılan klinik muayenesinde; hiperemik dişeti dokusu, yoğun plak ve diş çürükleri tespit
edilmiş, ancak kronik periodontitis bulgusuna rastlanmamıştır. Ön açık kapanışı bulunan hastada diş sürme
zamanlarının normal olduğu görülmüştür.
Sonuç: Hastanın restoratif tedavileri yapılmış ve ağız hijyen tavsiyeleri velisine sunulmuştur. Dental literatürde çok az sayıda rastlanılan bu hastalar, beslenme ve yutkunma problemleri olduğundan çürük risk grubundadırlar. Bu nedenle, bu orofasiyal sendromun bulgularının bilinmesi çocuk diş hekimliği açısından önemlidir.

Zeynep IŞIK, Erciyes Üniversitesi Diş Hekimliği Fakültesi - Pedodonti Anabilim Dalı,
GİRİŞ: Osteogenezis imperfekta (Oİ) klinik olarak kırılgan kemik hastalığı olarak bilinmektedir. Kemikte
kırılmalar ve çatlamalar ile karakterize kalıtsal bir hastalıktır. Tip I kollajenin her iki zincirindeki genlerin
(COLIA1 ve COLIA2) mutasyonu sonucu ortaya çıktığı belirtilmiştir. Tip I Oİ’da kollajen miktarında azalma
görülürken, Tip II, III ve IV Oİ’da kollajen sentezinde hem nitel hem de nicel değişiklikler görülmektedir. Bu
hastalıkta, Tip I kollajenden zengin dokuların tamamı etkilenebilmektedir. Oİ görülen hastalarda, mavi sklera,
dentinogenezis imperfekta, anormal kemik şekillenmeleri, büyüme geriliği, saç kaybı, deride incelme, eklemlerde gevşeklik ve aşırı hareketlilik yaygın olarak izlenmektedir. Klinik değerlendirme ile birçok vaka teşhis
edilebilmekle birlikte, bazı olgularda deri biyopsisi ve genetik testlere başvurulabilir. Genetik testler : -Oİ’nın
önceden tanı konulmamış durumunu, - Bir ebeveynin Oİ’nın mutasyona uğramış dominant formunun mozaik
taşıyıcısı olup olmadığını, - Aileleri veya yakınlarında OI’ nın resesif formunun taşıyıcısı olup olmadığını
gösterebilir.
VAKA RAPORU: İki farklı ailenin çocukları olan 8 yaşında erkek ve 13 yaşında kız hasta, Erciyes Üniversitesi Diş Hekimliği Fakültesi Pedodonti Kliniği’ne dişlerde kırılma, renklenme ve çürük şikayetleri ile başvurmuşlardır. Alınan anamnez ve klinik muayene sonucunda hastalara osteogenesiz imperfekta teşhisi konuldu.
Klinik ve radyografik muayenede hastalarda osteogenesiz imperfekta ile birlikte dentinogenezis imperfekta
tespit edildi. Aile hikayeleri sorgulandığında hasta yakınlarında da benzer şikayetlerin olduğu öğrenildi. Soyağacı değerlendirmesi sonucu hasta olma ihtimali olan bireyler kliniğe çağırılarak iki ailede toplam 18 kişide
osteogenezis imperfekta olgusu tespit edildi.
SONUÇ: İki ailenin de aile hikayesi sonucu soyağacları osteogenesiz imperfekta açısından değerlendirilmiştir. Bazı vakalarda otozomal dominat geçiş gözlenmekle birlikte, otozomal resesif geçişlere de rastlanmıştır. Ailenin diğer fertlerinde hastalığın teşhisinde, soyağacı incelemesinin önemli olduğu değerlendirilmiştir.

Giriş: Amelogenezis imperfekta, süt ve daimi dentisyonda mine gelişimini olumsuz etkileyen herediter bir
anomali türüdür. Bu anomali, minenin zayıf gelişimi ya da tamamen eksikliği ile karakterizedir. Amelogenezis imperfektada minedeki irregüler yapıya ilave olarak konjenital diş kayıpları, kapanış bozuklukları, pulpal
kalsifikasyonlar, dentin displazileri, kök ve kron rezorbsiyonları, hipersementoz, kök malformasyonları ve
dişlerin erüpsiyonunda anomaliler görülebilir.
Vaka raporu: 14 yaşındaki kız hasta estetik görünüm ve dişlerinde hassasiyet şikayetiyle Kırıkkale Üniversitesi Diş Hekimliği Fakültesi Pedodonti Kliniği’ne başvurmuştur. Hastanın ağız içi muayenesinde dişlerin mine
yüzeylerinde yer yer beyaz opak ve sarı-kahverengi lekeler gözlenmiştir. Ağızdaki tüm molar dişlerde çürük
alanlara rastlanmıştır. Aynı zamanda posteriorda çapraz kapanış olduğu tespit edilmiştir. Klinik ve radyolojik
değerlendirme sonucu; ağızda tüm yirmi yaş dişlerinin ve alt sol ikinci molar dişin gömülü olduğu tespit edilmiştir. Alt sol ikinci molar dişin kronunda gelişimsel bir anomali olduğu görülmüştür. Bu dişe çekim endikasyonu konularak alt sol yirmi yaş dişinin ikinci molar boşluğuna ortodontik olarak sürdürülmesi planlanmıştır.
Sonuç: Bazı dişlerin agenezisi veya gömülü kalması, kapanış bozuklukları gibi problemlerden dolayı, bu hastalarda diş tedavilerinin uzun süreli ve multidisipliner yaklaşımla yapılması zorunlu hale gelmektedir.

İpek ŞAHIN, Akdeniz University, Faculty of Dentistry - Pediatric Dentistry,
GİRİŞ: Tükürük bezi taşı (TBT) en sık görülen tükürük bezi hastalığı olmasına rağmen, çocuk hastalarda
nadir olarak görülmektedir (%3). Anatomik faktörler nedeniyle en çok submandibular bez etkilenmekte ve
olguların çoğunda kanalın distal bölgesinde bulunmaktadır. Etiyolojisi ve patolojisi henüz kesin olarak bilinmeyen bu rahatsızlığın tedavisi, tükürük akışının stimüle edilerek taşın spontan olarak atılmasının sağlanması,
sialoendoskopi, cerrahi olarak taşın ve/veya tükürük bezinin uzaklaştırılması, ekstrakorporal şok dalga lithotripsy, intrakorporal lazer gibi yöntemlerle yapılabilmektedir. Bu çalışmada, bir çocuk hastada submandibuler
TBT olgusunun tanı ve tedavi planının sunulması ve erken teşhisin öneminin vurgulanması amaçlanmıştır.
OLGU RAPORU: Sistemik olarak sağlıklı 10 yaşındaki erkek hasta, alt çenesinin sol tarafında şişlik, ağrı ve
çiğneme güçlüğü şikâyeti ile kliniğimize başvurmuştur. Hastaya yapılan klinik muayenede, ağız tabanının sol
ön bölgesinde bimanual palpasyonda şişlik hissedilmiş olup, Wharton kanalının ucunda TBT tespit edilmiştir.
Yapılan radyografik değerlendirmede ise, ağız tabanının sol kısmında TBT ile uyumlu radyoopak görüntü
olmamasına rağmen, sol submandibular tükürük bezi kanalında bulunan TBT nedeniyle hastada, -akut sialodenit- geliştiği sonucuna varılmıştır. TBT, tükürük bezi kanal ağzının minör cerrahi girişimle genişletilmesinin
ardından cerrahi olarak çıkarılmıştır.
SONUÇ: Boyutları, 1 - 10 mm arasında değişen TBT’nin her yıl 1-1.5mm büyüdüğü bildirilmektedir. Bu
nedenle erken teşhis önemli olup, yeterli tükürük salgısının gerçekleştirilememesi, enfeksiyon riskinin artması, artan ağrı ve şişlik nedenleriyle hastanın yaşam kalitesinin düşmesi gibi bir çok komplikasyonun ortaya
çıkmasını engelleyebilmektedir. Çocuklarda görülen TBT’ler semptomlu veya semptomsuz olabilir, bu nedenle rutin muayenede dikkat edilmesi gerekmektedir. Şüphelenilen durumlarda detaylı tetkikler yapılarak,
hastanın ilgili hekime yönlendirilmesi, erken tanı ve tedavinin sağlanması açısından büyük önem taşımaktadır.

SERVİKAL TÜBERKÜLOZ LENFADENİTLİ BİR OLGUDA TEŞHİSTEN TEDAVİYE
Derya CEYHAN, Faculty of Dentistry - Pediatric Dentistry,
Giriş: Tüberküloz, sağlık alanındaki ilerlemelere rağmen dünya çapında, özellikle de gelişmekte olan ülkelerde önemli bir sağlık problemi olmaya devam etmektedir.
Genel Bilgiler: Son yıllarda, ekstrapulmoner tüberküloz olgularında artış olduğu rapor edilmekte ve çocuk
ve adölesan bireylerin daha fazla risk altında olduğu ifade edilmektedir. Servikal bölgede görülen lenf nodu
tüberkülozu ise ekstrapulmoner tüberkülozun en sık görülen formudur.
Olgu Raporu: Muğla ilinin Fethiye ilçesinin bir köyünden, 12 yaşındaki kız hasta, sağ submandibular bölgede
3 aydır varolan, sert, ağrısız şişliğin dişsel açıdan değerlendirilmesi için kliniğimize başvurdu. Alınan hikayesinde, herhangi bir sistemik rahatsızlığı ve şikayeti olmadığı, bu şişlik için farklı sağlık merkezlerinde tıp
ve diş hekimlerince çeşitli ilaç tedavileri uygulandığı, şişliğin gerilemediği büyümeye devam ettiği, yapılan
ultrason değerlendirmelerinde benign lenf nodu büyümesi belirlendiği kaydedildi. Hastanın klinik ve radyografik muayenesinde bu şişliğe sebep olabilecek herhangi bir dişsel patolojiye rastlanmadı ve sistemik kaynaklı
olabileceği düşünülerek Kulak Burun Boğaz servisinden konsultasyon istenildi. Bu serviste yapılan ultrason
incelemesi, biyopsi ve uygulanan ilaç tedavisinden sonuç alınamayınca hastanın Pediatri servisine yönlendirildiği, değerlendirmeleri takiben Pediatri servisinin talebiyle Kulak Burun Boğaz servisi tarafından yapılan
eksizyonel biyopsinin patolojik raporunda tüberküloz tanısı bildirildiği öğrenildi. 7 aydır tüberküloz tedavisi
devam eden hastanın kontrolünde, şişliğin gerilediği görüldü ve ebeveyn, bu aşamada, 8 ay önce kesime giden
ineklerine tüberküloz teşhisi konulduğunu tesadüfen söyledi. Herhangi bir acil dişsel tedavi ihtiyacı olmayan
hastanın dişsel tedavilerinin, tüberküloz tedavisi tamamlandıktan sonra yapılması planlandı.
Sonuçlar: Çocuklarla ilk karşılaşan hekimler olan pedodontistler; hastaların anamnezlerinin tam alınarak
derinleştirilmesi, ayrıntılı bir anamnezin hastalıkların erken teşhisindeki öneminin ebeveynlere vurgulanması, uygulanan tedavilere dirençli olgularda disiplinler arası yönlendirmelerin ve çalışmanın uygun şekilde planlanması ile tüberküloz gibi bulaşıcı hastalıkların teşhis edilerek korunma sağlanmasında önemli
bir görev üstlenmektedirler. Klinisyenler, her hastanın bulaşıcı hastalıklar açısından potansiyel bir risk olabileceğini unutmamalı ve uygulanacak her türlü işlemde korunma önlemlerini tam olarak sağlamalıdırlar.

Giriş: Dentigeröz kistler radiküler kistlerden sonra çenenin en sık gözlenen ikinci odontojenik kistleridir.
Çoğunlukla mandibular gömülü 20 yaş dişleriyle ilişkiliyken, çocuklarda dentigeröz kistler sıklıkla erüpsiyon
halindeki dişle ilişkili olarak gelişir. Çenede gömülü olarak kalmış kanin, kesici ve premolar dişlerle de ilişkili
olabilir. Gömülü dişin etrafındaki folikül epitelinden kaynak aldığı düşünülmektedir. Genellikle radyolojik
incelemeler sonucu tespit edilirler. Sekonder olarak enfekte olmadıkları sürece ağrı, şişlik ya da herhangi bir
başka semptom göstermezler. Bu olgu sunumunda, mandibula anterior bölgede erüpsiyon halindeki alt keser
dişle ilişkili dentigeröz kistin multidisipliner yaklaşımla tedavisi sunulmaktadır.
Vaka Raporu: Mandibula anterior bölgede 81 ve 82 numaralı dişleri ağızda bulunan 10 yaşında kız hasta bu
bölgedeki daimi dişlerin sürmemiş olması şikayetiyle Kocaeli Üniversitesi Diş Hekimliği Fakültesi Pedodonti
Kliniği’ne başvurmuştur. Klinik ve radyolojik (panoramik radyografi ve konik ışınlı bilgisayarlı tomografi)
incelemeler sonucunda 2,5x2x1.5 boyutlarında, gömülü 41 numaralı diş ile ilişkili, ağrısız, unilokuler ve radyolusent bir lezyon izlenmiştir. Gerekli hazırlıklar yapıldıktan sonra genel anestezi altında 81, 82 numaralı
dişler çekilmiş olup, kist ile ilişkili 41 numaralı diş çene içerisinde bırakılarak kist eksize edilmiştir.
Sonuç: 41 numaralı dişin sürmesi bakımından ilerleme kaydedilmiş olup, kist boşluğunun değerlendirilmesi
ve rutin klinik-radyolojik kontroller için hasta izlenmektedir.

Giriş: Süpernümerer (SN) dişlerin etyolojisi halen tam olarak bilinememektedir. Farklı formlarda görülebilmekte ve kalıcı dişlerin gömük kalması gibi farklı lokal bozukluklara sebep olabilmektedir. Bu olgu raporunda
çift yumurta ikizlerinde görülen SN dişler ve yönetimi sunulmaktadır.
Olgu raporu: 12 yaşındaki çift yumurta ikizleri üst çenede sürmeyen orta kesici dişleri nedeni ile İstanbul Üniversitesi Diş Hekimliği Fakültesi Pedodonti Anabilim Dalı’na başvurmuştur. Yapılan tıbbi anamnezde herhangi bir sistemik hastalık veya sendrom bulunmadığı, dişlere dair anamnezde ise geçmişte herhangi bir dental
travma hikayesi bulunmadığı görülmüştür. Panoramik radyografide A ikizinde 2 gömük SN dişe, B ikizinde
4 gömük SN diş ve üst çene süt orta kesici dişe rastlanmış, SN dişlerin her iki çocukta da premaksilla ve alt
çene küçük azı bölgelerinde yer aldığı tespit edilmiştir. İlk olarak halen ağızda var olan süt dişi ve SN dişler
lokal anestezi altında çekilmiştir. A ikizinde 4 aylık takip döneminde sürekli üst kesici diş tamamen sürmüştür.
B ikizinde 1 yıllık takip döneminde kesici dişlerden biri sürmemiş ve dişin sürdürülmesine karar verilmiştir.
Tedavi kapsamında ön bölgedeki yer kaybının yeniden kazanılması, gömük orta kesici dişin cerrahi olarak
üzerinin açılması ve 6 ay süre ile sürdürülmesi yer almaktadır.
Sonuç: Olgu raporundaki ikizlerde farklı sayıda SN dişlerin bulunmasına karşın, bu rapor SN dişlerin etyolojisinde genetik faktörlerin etkisini açık bir biçimde desteklemektedir.

Mine KORUYUCU, Istanbul University, Faculty Of Dentistry - Pedodontics,
Figen SEYMEN, Istanbul University, Faculty Of Dentistry - Pedodontics,
Koray GENÇAY, Istanbul University, Faculty Of Dentistry - Pedodontics,
Giriş: Erken çocukluk çürükleri (EÇÇ), gelişmiş ülkelerde pediatrik hasta populasyonunun %1-12 kadarını,
az gelişmiş ülkelerde %70 kadarını etkilemektedir. Şiddetli erken çocukluk çürüklerinin klinik görünümü çok
belirgindir. Erken çürük oluşumu üst çene süt kesici dişleri takiben, alt ve üst çene birinci süt azı dişlerini ve
alt çene köpek dişlerini etkilemektedir. Şiddetli çürük oluşmuş ön bölge süt dişlerinin estetik tedavisi pedodontistler için büyük zorluk oluşturmaktadır.
Amaç: Bu olgu sunumunun amacı, pediatrik zirkonyum kuronlar kullanılarak estetik ve fonksiyonel rehabilitasyonun sağlanmasıdır. Olgu Sunumu: 3 yaşındaki erkek olgu pedodonti kliniğine üst ve alt süt birinci
azılarında ağrı şikayeti ve ailenin ön bölge süt dişlerindeki estetik şikayet ile başvurmuşlardır. Ağız içi muayenesinde arka bölge süt dişlerinde derin dentin çürükleri ve ön bölge süt dişlerinde orta derecede çürük lezyonları saptanmıştır. Klinik ve radyografik muayenede dentoalveolar abse formasyonuna rastlanmamıştır. Üst
ve alt çene süt azılarının pulpa tedavileri sonrası, çürük kesici ve azı dişlerinin pediatrik zirkonyum kuronlar
ile restorasyonları gerçekleştirilmiştir.
Sonuç: Tedavi planı hastanın yaşına, sosyoekonomik durumuna, çürüğün şiddetine, hastanın ağız içi
durumuna, bireysel fonksiyonel ve estetik ihtiyaca göre planlanmalıdır. Erken diş kaybının ve artmış doku yıkımının önlenebilmesi için erken yaşlarda tedaviye başlanması önemli olmaktadır.

ÜZERİNE ETKİLERİNİN DEĞERLENDİRİLMESİ
Asım DANE, Diş Hekimliği - Pedodonti,
Taşkın GÜRBÜZ, Diş Hekimliği - Pedodonti,
Amaç: Birçok sistemik hastalığın ilk bulgusu ağızda ortaya çıkmaktadır. Ağız boşluğu GİS’in ilk basamağını
oluşturmaktadır. Çocukluk çağında karşılaşılan en sık GİS hastalıklarından birisi gastrit hastalığıdır. Çalışmamızda gastritin en sık bakteriyel sebebi olan HP’nin dental plakta varlığının tespiti ve gastritli hastaların
ağız bulgularının (oral sağlık durumları, beslenme şekilleri, diş fırçalama sıklığı, tükürük pH, akış hızı, tamponlama kapasitesi) sağlıklı bireylerden oluşan kontrol grubuyla karşılaştırılması, bu hastaların çürük riski
yönünden değerlendirilmesi amaçlanmıştır.
Materyal ve Metot: Çalışmamıza yaşları 5-15 arasında değişen 35 gastrit hastası ve 35 sağlıklı hasta dahil
edilmiştir ve bireylerin ağız içi muayeneleri yapılarak, dental plak ve tükürük örnekleri toplanarak analizler
yapılmıştır.
Bulgular: HP gastritli hastaların 29’unun (% 82.9) dental plak örneklerinde HP (+) olarak saptanmıştır.Gastritli çocukların ortalama DMFT ve dft skorları sırasıyla 4.37±1.41 ve 1.97±1.68 olarak bulunmuştur.
Sonuç: Çalışmamızda elde edilen veriler ışığında dental plakta HP’nin izole edilmesi ile oral kavitenin gastrik
mukoza gibi rezervuar alanı olabileceği ve gastrik hastalıkların önlenmesinde ağız hijyeninin önemli bir yer
tutabileceği sonucuna ulaşılmıştır.

ÇOCUKLARDA ÇÜRÜK OLUŞUMU VE ÇEVRESEL FAKTÖRLER
Yard.Doç.Dr. ESRA KIZILCI
İnönü Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı, Malatya
Yeni doğanın ağız ortamında kolonize olan mikroorganizmalar, gelecekteki flora için model oluşturmaktadır.
Ağızda oluşan mikrobiyal ekosistemde, yaşam boyunca çeşitli değişimler meydana gelmektedir. Görülen
değişimde, ağız bakım alışkanlıkları, yöresel ve sosyo-kültürel farklar gibi faktörler mevcut bakterilerin
sayı ve çeşitliliğini değiştirerek etkili olabilmektedir. Diş çürüğünün oluşmasından sorumlu tutulan Mutans
Streptokok (MS)’ lar genellikle ilk dişlerin sürmesinden sonra ağız boşluğuna yerleşmektedir. MS geçişinin bu dönemde artmasının sebebi, mikroorganizmanın tutunmak için ağız içinde düz yüzeylere duyduğu
ihtiyaçtır. Genel kanı MS’ in belirli bir dönemde edinildiği yönündedir. Yeni doğanın MS ile enfekte olma
sürecinin 8-10 aylık dönemde tetiklendiği ve 19-31. aylar arasında en üst düzeye ulaştığı saptanmıştır. Bebeklerin bu mikroorganizmaları enfekte bireylerden, özellikle de annelerinden kazandıkları düşünülen 19-31
ay aralığına “birinci enfektivite penceresi” denilmektedir. 6-12 yaşlarında ise “ikinci enfektivite penceresi”
ortaya çıkmaktadır.
Diş çürüğünün enfeksiyöz, aktarılabilen bir hastalık olduğunun tanımlanmasından sonra çürüğün oluşumunu
engellemeye ve geçiş yollarını belirlemeye yönelim artmıştır. MS’ ler ağız dışında çok sınırlı yüzeylerde
canlılıklarını koruyabilirler ve yayılımlarında tükürük transferi en önemli etkendir. Bebekte bakterilerin
geçişi ve ağız ortamına yerleşmesi çoğunlukla anneden, babadan (aile-içi) ve bakıcılarından olmaktadır. Ancak çocukta aile bireylerinden farklı genotipte S. mutans klonları tespit edilmiş, çocuğun diğer kaynaklardan
da enfekte olabileceğini göstermiştir. Geçişte tükürük transferine neden olan alışkanlıkların, ağzında yüksek
miktarda MS bulunan bireylerin ve birlikte geçirilen sürenin etken olduğu görülmüştür. Anne bebeğini yakın
temasla enfekte mikroorganizmalara maruz bırakmasına karşın, sütüyle ve bebeğe plasenta yoluyla çeşitli
antikorlar transfer ederek bebeğin bağışıklık kazanmasını da sağlamaktadır.
Bireyin MS ile erken tanışması, özellikle süt dişlenmenin hemen başında yaygın MS varlığı, ağız içinde erken ve hızlı çürük oluşumunu tetiklemektedir. Ülke genelinde yürütülecek toplum ağız-diş sağlığı eğitim ve
uygulamaları ile bireylerin çürük oluşumu ve engellenmesi konusunda bilinçlendirilip, çürüğün başlamadan
önce engellenmesi konusunda önemli adımlar atılabileceği düşüncesindeyiz.

DİŞ ÇÜRÜĞÜ VE GENETİK İLİŞKİSİ
Yard.Doç. Dr. MERVE BAYRAM
İstanbul Medipol Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı, İstanbul
Diş çürüğü kompleks, kronik, multifaktöriyel bir hastalık olup bugün dünya nüfusunun %80’inden fazlasını
etkileyen dünya çapında bir temel halk sağlığı problemi oluşturmaktadır. Diş çürüğünün, ağrı ve acı çekilmesi,
fonksiyon kaybı, yaşam kalitesinin düşmesi gibi bireylerin ve toplumların üzerindeki etkisi oldukça önemlidir. Diş çürüğü, konak ve çevresel faktörler başta olmak üzere birbiri ile etkileşimli pek çok risk faktörü ile
ilişkilidir. Ancak hastalığın oluşmasına neden olabilen risk faktörlerinin bilinmesine karşın aynı çevresel risk
faktörlerine maruz kalan bireylerin DMFT değerlerinde farklılıklar bildirilmiştir. Maruz kaldıkları çevresel
risk faktörlerinden bağımsız olarak çürüğe karşı daha hassas ve çok dirençli bireyler bulunmaktadır. Çürüğe
daha hassas ve dirençli bireylerin varlığı, araştırmacıları diş çürüğünün genetik yapısı üzerine çalışmalara
yöneltmiştir. Diş çürüğü ve genetik ilişkisi şimdiye kadar deneysel, gözlemsel, bağlantı ve ilişki çalışmaları
ile kanıtlanmıştır. Diş çürüğü ve genetik alanında bilgilerin artması diş çürüğü riski olan bireylerin belirlenmesine yol açacak, çürüğün önlenmesi ve tedavisi için kalıcı çözüm yolları bulunmasına yardımcı olacaktır.

ÇOCUKLARDA GÖRÜLEN ÇÜRÜKLERİN PERİODONSİYUMA ETKİSİ
Yard.Doç. Dr. GÜLSÜM DURUK
İnönü Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı, Malatya
Çürük lezyonu, süt dişlerinde daimi dişlere kıyasla daha hızlı ilerlemektedir. Erken çocukluk çağı çürüklerinde
kole bölgesinde çürük lokalizasyonu oldukça yaygındır. Çürüğe bağlı kole bölgesindeki gıda retansiyonu
sonucu bu bölgede biriken bakteriler ve konağın savunma cevabı arasındaki dengenin konak aleyhine
bozulması ile lokal enfeksiyonel bir hastalık olan gingivitis oluşmaktadır.
Süt azı dişleri, geniş ve düz ara yüz değim alanları gibi anatomik özelliklere sahip olmaları sebebiyle süt dişleri
içerisinde çürüğe en yatkın dişlerdir. Süt dişlenmesinde sırt sırta kaviteler olarak da bilinen süt I. azı dişinin
distali ve süt II. azı dişinin mezialini içine alan çürükler yaygın olarak görülmektedir. Bu çürüklerin hızlı
ilerlemesine bağlı olarak geniş kavitasyonlar oluşmaktadır. Bu kavitasyonlara gıda birikimi ve bu gıdaların
periodonsiyum içine gömülmesi (food impaction) sonucu oluşan periodontal harabiyet sık karşılaşılan
durumlardandır.
Dişeti bölgesine kadar uzanan çürüklerde plak indeksi, gingival indeks, dişeti oluğu sıvısı (DOS) hacminde
artış ve DOS komponentlerinde değişimler gözlenmektedir. Süt azıların geniş harabiyetli ara yüz çürüklerinde
ileri aşamalarda ataşman kaybı ile karşılaşmak muhtemeldir. Çürüğün restore edilmesi sonucu bu parametreler
çürüksüz dişlerdekine benzer bulgular sergilemektedir. Bu durum plak birikimi için retansiyon yeri olan
kavitelerin kapatılması, ara yüz kontağının kaybolduğu dişlerde periodonsiyuma irritan etki yapan gıda
gömülmesinin yeniden kazanılan ara yüz kontağıyla elimine edilmesi, gıda birikimi ve buna bağlı ağrı
şikayetiyle kullanılamayan dişlerin restorasyon sonrası kullanımına bağlı olarak çiğnemenin katkısıyla
mekanik temizliğin geri kazanılmasından kaynaklıdır.
Diş ve dişetinin bir bütünlük içinde olduğu gerçeğinden hareketle, periodontal sağlığın tehdit edilmesini
engellemek adına çürüklü dişlerin restore edilmelerinin önemi unutulmamalıdır.
Anahtar kelimeler: Çürük, DOS, gıda gömülmesi

REVASKÜLARİZASYON TEDAVİSİNDE KULLANILAN ÜÇLÜ ANTİBİYOTİK PATI İLE
İLGİLİ KARŞILAŞTIRMALI ÇALIŞMALAR
Yard.Doç. Dr. MERVE AKÇAY
Izmir Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı, İzmir
Revaskülarizasyon tedavisi, vitalitesini kaybetmiş açık apeksli genç daimi dişlerde geleneksel apeksifikasyon
tedavisine alternatif konservatif bir tedavi seçeneğidir. Bu tedavi seçeneği mineralize dokularla kök duvarının kalınlaşmasına ve fizyolojik kök gelişiminin devam etmesine imkan tanımaktadır. Revaskülarizasyon
tedavisinde en önemli aşamalardan biri kök kanal sisteminin dezenfeksiyonudur. Kök kanal sisteminden enfeksiyonun etkin bir şekilde elimine edilebilmesi için antibiyotik kombinasyonları kullanılmaktadır. Güçlü
antimikrobiyal etkisi nedeniyle metronidazol, siprofloksasin ve minosiklinden oluşan geleneksel üçlü antibiyotik patının araştırmacılar tarafından sıklıkla tercih edildiği görülmektedir. Konuyla ilgili yayınlanan olgu
raporlarında üçlü antibiyotik patı kullanımını takiben periapikal lezyonlarda önemli oranda azalma olduğu,
apeksin kapandığı, dentin duvarlarının kalınlaştığı ve vitalite testine pozitif yanıt alındığı bildirilmiştir. Olumlu özelliklerine rağmen, minosiklin içeren üçlü antibiyotik patının diş kuronunda renklenmeye neden olduğu, kök kanal sisteminden uzaklaştırılmasının zor olduğu, kırılma direncinde azalmaya neden olduğu sınırlı
sayıda çalışmada rapor edilmiştir. Son zamanlarda minosiklin yerine amoksisilin, sefaklor ve doksisiklin gibi
alternatif antibiyotiklerin kullanımı ya da minosiklin içermeyen ikili antibiyotik patı kullanımı önerilmiştir.
Fakat revaskülarizasyon tedavisinde bu antibiyotik pat kombinasyonlarının bir arada karşılaştırılmalı olarak
değerlendirildiği çalışmalar oldukça sınırlıdır.
Bu sunumda farklı üçlü antibiyotik pat kombinasyonlarının dişlerde oluşturduğu renklenme, kök kanalından
uzaklaştırılma etkinlikleri, kanal dolgu maddesinin, kalsiyum silikat bazlı simanların ve self etch adeziv bir
sistemin bağlanma dayanımına katkıları, maturasyonunu tamamlamamış dişlerin kırılma direncine etkisi gibi
farklı konularda yapılan çalışmalar hakkında bilgi verilecektir.

Amaç: Çalışmamızın amacı, L. reuteri’nin oral mikrobiyolojik çerçeve içerisine dahil olabilme ve S. mutans’la yarışabilme yeteneğinin in vivo koşullarda sıçanlarda araştırılmasıdır.
Gereç ve Yöntem: Tükürüklerinde S. mutans ve L. reuteri bulunmayan 1 aylık 24 adet Spraque Dawley sıçan
rastgele üç gruba ayrılmıştır. Birinci grup (Kontrol grubu) 2. ayda S. mutans ile infekte edilmiştir. 3. ,4. ve 5.
aylarda tükürük mikrobiyolojik analizleri yapılarak S. mutans sayıları belirlenmiştir. İkinci grup (Probiyotik I
grubu) 2. ayda S. mutans ile 3. ayda L. reuteri (BioGaia Damla® (Eczacıbaşı, Sanico N.V, Belçika)) ile infekte edilmiştir. Üçüncü grup (Probiyotik II grubu) ise 2. ayda L. reuteri (BioGaia Damla® (Eczacıbaşı, Sanico
N.V, Belçika)) ile 3. ayda S. mutans ile infekte edilmiştir. Probiyotik I ve Probiyotik II gruplarının 3. ,4. ve 5.
aylarda tükürük mikrobiyolojik analizleri yapılarak S. mutans ve L. reuteri sayıları belirlenmiştir. Bulgular:
Kontrol grubu ve Probiyotik I grubunda, S. mutans sayıları 3. ve 4. ayda giderek artmış, 5. ayda azalmıştır,
Probiyotik II grubunda 4. ayda artmış, 5. ayda azalmıştır. Probiyotik I grubunda, L. reuteri sayıları 4. ve 5.
ayda giderek artmıştır, Probiyotik II grubunda 3. ,4. ve 5. aylarda her ay artmıştır.
Sonuç: Probiyotik I grubunda S. mutans seviyeleri Kontrol grubuna paralel olarak azalırken, L. reuteri seviyeleri artmıştır. Probiyotik II grubunda ise S. mutans değerleri Kontrol grubuna göre daha yüksek seviyede
başlayıp tekrar azalırken, L. reuteri seviyeleri artmıştır. Bu nedenle, L. reuteri’nin ilk kolonizasyon suşu olarak
tükürükte daha iyi bir kolonizasyon gösterdiği düşünülebilir. Ancak, L. reuteri ile daha fazla sayıda kolonizasyon çalışması yapılması gerekmektedir.

Amaç: Konjenital diş eksikliği prevelansının değerlendirildiği çalışmalara bakıldığında, farklı bölgelerde çok
farklı değerler elde edildiği gözlenmektedir. Bunun yanı sıra konjenital diş eksikliğinin en sık gözlendiği
dişler, alt ve üst çenedeki dağılımı, simetrik veya tek taraflı gözlenme sıklığı açısından da bir fikir birliği bulunmamaktadır. Prevelans değerlerinde gözlenen farklılıkların nedeni olarak yaş, cinsiyet, etnik köken çalışma
grubundaki dağılım farklılıklarının yanı sıra değerlendirme metotları ile araştırmacı faktörünün de bir etken
olabileceğini gösterilmiştir. Literatürde dental anomalilerin tespitinde araştırmacının kendisi ile uyum düzeyi
değerlendirilmesine karşın, araştırmacılar arasındaki uyum düzeyi üzerinde çok az durulduğu görülmektedir.
Buna göre; yapmış olduğumuz çalışmada araştırmacının tecrübe ve bilgi düzeyinin konjenital diş eksikliği
prevelans değeri üzerindeki etkisinin değerlendirilmesi amaçlanmıştır.
Gereç: Erciyes Üniversitesi Diş Hekimliği Fakültesi Pedodonti Anabilim Dalı kliniğinde muayenesi yapılan,
yaşları 7 ile 16 arasında değişen toplam 5318 çocuk hastadan alınmış panaromik radyografilerin retrospektif
değerlendirmesi yapılmıştır. Radyograflar sırasıyla bir diş hekimliği öğrencisi, bir pedodonti doktora öğrencisi, deneyimli bir pedodonti öğretim üyesi tarafından değerlendirildikten sonra, 3 kişiden oluşan bir kurul (2
deneyimli pedodonti öğretim üyesi ile bir radyoloji öğretim üyesi) tarafından değerlendirilmiştir. Araştırmacılar arasındaki farklılıklar Mc Nemar ve genel uyum testleri ile değerlendirilmiş, hesaplamalarda SPSS 20.0
(IBM SPSS Inc., Chicago, IL) programı kullanılmıştır.
Bulgular: Çalışma sonucunda konjenital diş eksikliğinin tespitinde araştırmacı tecrübe düzeyleri arasında istatistiksel olarak anlamlı düzeyde bir farklılık bulunduğu tespit edilmiştir (p<0,001). Buna karşın araştırmacıların konjenital diş eksikliği prevelansı değerleri arasında farklılık bulunmamıştır (p>0,05).
Sonuç: Konjenital diş eksikliğinin tespitinde diş sayısı açısından araştırmacı deneyimi önemli bir faktör olarak görülmesine karşın, araştırmacıların konjenital diş eksikliği bulunmayan panoramiklerdeki yanlış pozitif bulguları
sebebiyle prevelans değerlerinde gözlemciler arasında istatistiksel olarak anlamlı bir farklılık tespit edilememiştir.

Aim: Çölyak hastalığı tüm dünyada olduğu gibi ülkemizde de sık görülen immun kökenli bir sistemik hastalıktır. Ülkemizde her 110 çocukta 1 görülen bu hastalığın erken tanısında çocuk dişhekimleri önemli rol
oynamaktadır.
Methods: Çalışmamıza 3-19 yaş aralığında 132 çölyak tanısı almış çocuk ve 55 sağlıklı çocuk dahil edilmiştir.
E.Ü. Çocuk Hastanesi’nde takipleri yapılan hastaların dosyaları incelenmiş ve hastalığın şiddetiyle bilgiler
kaydedilmiştir. Tanı yaşları değişkenlik gösteren hastaların, tanı öncesi dişhekimi ziyaretleri kaydedilmiş;
hastalar mine defekti varlığı ve şiddeti, rekkürrent aftöz stomatit yakınmaları açısından incelenmiştir. Mine
defektleri Aine sınıflandırmasına göre sistematik ve kronolojik olarak değerlendirlmiştir.
Results: Çölyaklı çocukların % 57,57’sinde mine defekti gözlenirken, sağlıklı çocuklarda bu oran % 7,57
olarak bulunmuştur. Rekkürrent aftöz stomatit çölyaklı çocukların % 30,3’ünün temek şikayetleri arasında
görülmüştür. Tanı yaşı geç olan çocuklar da her iki oral patolojinin daha çok görüldüğü, mine defektlerinin
siddetinin arttığı tespit edilmiştir.
Conclusion: Çocuk doktorlarının ön tanı amacıyla erken dönemde istedikleri dişhekimi konsultasyonları, hastalıkla ilişkili mine defektlerinin teşhisinde donanımlı olunması durumunda; hastalığın seyrini etkileyerek kilo
kaybı ve bağırsak nekrozlarının azalmasına yardımcı olur.

AVULSİYON SONRASI GECİKMİŞ REPLANTASYON: BİR OLGU SERİSİ

Giriş: Dental travmatik yaralanma sonrasında dişin alveoler soketten tamamen çıkmasına avulsiyon, yerinden
çıkan dişin tekrar yerine yerleştirilmesine replantasyon adı verilmektedir. Avulse olan daimi dişlerin replantasyonu kabul görmüş bir tedavi yaklaşımı olmasına rağmen replante edilen dişlerin uzun dönem prognozu hala
tartışmalıdır. Replante edilmiş dişin prognozunda en önemli faktör dişin ağız dışında kaldığı süre ve saklama
ortamıdır. Avulsiyon ile replantasyon arasındaki süre arttıkça replasman rezorbsiyonunun meydana gelme olasılığı artmakta, kök ucu açık dişlerde revaskülarizasyon olasılığı azalmaktadır. Amaç: Bu olgu serisinde geç
replantasyon olgularının uzun süreli takibi, tedavisi ve ortaya çıkan komplikasyonlar sunulacaktır.
Olgu Raporu: Bu çalışmada 2010-2014 yılları arasında İnönü Üniversitesi, Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı’na avulsiyon nedeniyle başvuran 8-13 yaş arası 10 hasta dahil edilmiştir. Kliniğimize dental
travma sonrası ortalama 1 gün (2 saat-3 gün) süresinde ulaşan 10 hastanın avulse olan 15 adet daimi kesici
dişine gecikmiş replantasyon tedavisi yapılmıştır. Hastalar ortalama 33 ay (18 ay - 48 ay) takip edilmiştir. Bu
olgularda, en sık karşılaşılan komplikasyonun (%47) replasman rezorbsiyonu sonucu dişin kaybedilmesi olduğu belirlenmiştir. 15 dişin 3’ ü avulse olduğunda kök gelişimini tamamlamamışken, bunlardan sadece 1 diş
kök gelişimine devam etmiştir.
Sonuç: Periodontal ligamentin yokluğunda ve kontaminasyon kontrol altındaysa en iyi sonucun ankiloz ve
replasman rezorbsiyonu olacağı tahmin edilebilmektedir. Bu süreç er ya da geç replantasyon prosedürünün
başarısızlıkla sonuçlanmasına neden olacaktır. Daimi kesici dişlerin replantasyonunda birincil amaç hastanın maksiller veya mandibuler anterior bölgesinin kemik gelişimi tamamlanana ve daimi bir protezin yapılabileceği zamana kadar dişin ağızda tutulmasıdır. Erken diş kayıpları mevcut alveol kemik yüksekliğinin
kaybolmasına ve orta hattın kaymasına neden olabilmektedir. Bu sebepler göz önünde bulundurulduğunda, daimi keser dişlerin geç de olsa replante edilmesi çocuğun çene ve yüz gelişimi açısından önemlidir.

DAİMİ DİŞLERDE GÖRÜLEN KRON KIRIKLARINDA 1 YILLIK TAKİP SONUNDA
OLUŞABİLECEK KOMPLİKASYONLARIN DEĞERLENDİRİLMESİ: PİLOT ÇALIŞMA
Esra KIZILCI, İnönü Üniversitesi - Pedodonti,
Pınar DEMIR, İnönü Üniversitesi - Pedodonti,
Amaç: Dental travmatik yaralanmalar çocukluk ve ergenlik çağının önemli sağlık problemlerindendir. Çocukların yaklaşık %50’si 15 yaşından önce dental travmaya maruz kalmaktadır (1). Daimi dişlerde en sık karşılaşılan travma tipi kron kırıklarıdır (%26-76). Bu çalışmanın amacı kron kırıklarının 1 yıllık takibi sonrasında
karşılaşılabilecek komplikasyonların belirlenmesidir.
Yöntem: Çalışmamıza 6-13 yaş aralığında, daimi dişinde kron kırığı bulunan 50 hastanın 70 dişi dahil edilmiştir. Sistemik hastalığı ve mental problemi olan hastalar çalışmaya dahil edilmemiştir. Çocukların velilerinden
detaylı anamnez alınıp, travma kayıt formları doldurulmuştur. Hastalar tedavi sonrası 1. yılda çağrılarak, klinik ve radyografik olarak oluşabilecek komplikasyonlar (restorasyonun kaybı, restorasyonda görülen başarısızlıklar, pulpa kanal obliterasyonu, pulpa nekrozu, kök gelişiminin durması, anormal mobilite, dişin kaybı,
rezorbsiyonlar) açısından incelenmiştir. Veriler istatistiksel olarak değerlendirilmiştir.
Bulgular: Çalışmaya katılan hastalarının ortalama yaşı 11’dir. Hastalardan %12’sinin travmadan sonra ilk
gün kliniğe başvurduğu, ortalama başvurma süresinin 5,8 ay olduğu belirlendi. Yaralanmaların en fazla yaz
mevsiminde gerçekleştiği (%58) ve en fazla etkilenen dişlerin üst santral dişler olduğu görüldü (n=63,%90).
26 dişte komplike, 44 dişte ise komplike olmayan kron kırığı bulunmaktaydı. Tedaviler değerlendirildiğinde;
2 hastada diş parçasıyla, 46 hastada ise yalnız kompozit dolgu ile restorasyonun tamamlandığı, 22 dişe kanal
tedavisi gerektiği görüldü. Bir yıllık takip sonrasında yapılan tedavi sonrası memnuniyet skalasında velilerin
restorasyonu görünüm (%77), renk (%79), boyut (%80) ve genel memnuniyet (%90) açısından başarılı buldukları görüldü. Klinik değerlendirmede; dişlerin %14’ ünde dolguda renklenme, %13’ünde dolgu kaybı, %3’
ünde renklenme görüldü, %69’ u ise klinik olarak başarılı kabul edildi. Kanal tedavilerinde klinik ve radyografik olarak herhangi bir başarısızlıkla karşılaşılmadı. Eşlik eden lüksasyon yaralanmaları, çeneler arası kapanış
ilişkisi, fırçalama alışkanlığı ve apeks gelişim durumu ile başarı arasında anlamlı ilişki bulunamadı (p<0,05).
Sonuçlar: Dental yaralanmalarda ortaya çıkabilecek muhtemel komplikasyonlar açısından uzun süreli klinik
ve radyolojik takip önemlidir. Travma sonrası ne gibi komplikasyonların ortaya çıkacabileceği ve kontrollerin
önemi hastalara ve ebeveynlere anlatılmalıdır.

kız çocuğunda tanımlanmıştır. Nadir olarak gözlenen otozomal resesif geçişli bu sendromun ağız içi bulguları
hakkında ise çok az bilgi mevcuttur. Genel ağız içi bulgularında diş etinde kanama, mukozada beyaz lekeler,
dudaklarda atrofi, eroyon ve pigmentasyon varlığı bildirilmiştir. Diş ve çevre dokular incelendiğinde ise süt
dişlerinin erken kaybı, gevşek kanamalı diş eti, erken dönemde başlayan ve hızlı ilerleyen periodontitis yaygın
gözlemlenmiştir. Bu olgu raporunda KS tanısı ile dental muayene ve tedavileri için kliniğimize gönderilmiş iki
kardeş hastanın klinik ağız içi bulguları ve uygulanan tedavilerin sunulması amaçlanmıştır.
Olgu Raporları: Olgu raporunda Kingler Sendromu tanısı ile konsültayona gönderilen birisi 2 yaşında erkek
ve diğeri 7 yaşında kız, iki kardeşin ağız içi ve dermatolojik muayene bulguları yanı sıra 7 yaşındaki hastaya
uygulanan tedavi prosedürü sunulmaktadır.
Sonuç: Kindler’in ilk tebliğinden bu yana 100’den fazla olgu bildirilmiş olmasına karşın Kingler sendromunun ağız içi bulguları hakkında yayınlanmış çok az vaka bildirimi bulunmaktadır. Bu vakalarda generalize
yaygın periodontitis en belirgin ağız içi bulgudur ve geleneksel cerrahi olmayan periodontal tedavinin bu
hastalarda faydalı olduğundan bahsedilmektedir. Buna göre; KS’li hastaların erken dönemde tespitinden sonra dental açıdan da oral hijyenlerin en üst düzeyde sürdürülmesi ve düzenli kontrollerinin yapılması gereken
olgularda da periodontal ve dental tedavilerinin yapılması gereklidir.
Anahtar Kelimeler: Kingler Sendromu, periodontitis, olgu, ağız bulguları, oral hijyen

ÇOCUKLARDA ARA YÜZ ÇÜRÜKLERİNİN BİYOKİMYASAL DOS PARAMETRELERİ VE
KLİNİK ÖLÇÜMLER ÜZERİNE ETKİSİ
Gülsüm DURUK, İnönü Üniversitesi, Diş Hekimliği Fakültesi - Pedodonti Anabilim Dalı,
Taşkın GÜRBÜZ, Atatürk Üniversitesi, Diş Hekimliği Fakültesi - Pedodonti Anabilim Dalı,
Hülya AKSOY, Atatürk Üniversitesi, Tıp Fakültesi - Biyokimya Anabilim Dalı,
Amaç. Bu çalışmada, çocuklarda süt azıların ara yüz çürüğüne bağlı periodontal harabiyetinin; OHİ-S, Pİ, Gİ,
SD, AK, DOS hacmi ve DOS’ta IL-1β, VEGF ve OC miktarlarına olan etkisinin belirlenmesi amaçlanmıştır.
Materyal ve Metot. Yaşları 5-8 arasında değişen, sistemik rahatsızlığı olmayan 22 çocuğun 38 kuadrantındaki
ara yüz çürüğüne bağlı periodontal harabiyetli süt azıları ve 22 adet çürüksüz üst süt kanin dişi çalışma kapsamına alınarak, süt azıların tedavisinden 6 ay sonra klinik ölçümlerde ve DOS parametrelerinde biyokimyasal
açıdan meydana gelen değişiklikler değerlendirilmiştir.
Bulgular. Çürüklü dişlerde sağlıklı dişlere oranla Pİ, Gİ, DOS hacmi ve DOS’ta IL-1β, VEGF, OC miktarları
yüksek bulunmuştur. Çürüklü dişlerin tedavisinden sonra bu dişlerde OC hariç tüm parametrelerde (Pİ, Gİ,
SD, AK, DOS hacmi, IL-1β, VEGF) düşüş gözlenmiştir (hepsi için p<0.0001). Bu dişlerde yine tedavi sonrası
Pİ, IL-1β, VEGF ve OC parametreleri çürüksüz dişlere yakın değerler sergilerken (hepsi için p>0.05), Gİ ve
DOS hacmi çürüksüz dişlere kıyasla daha yüksek bulunmuştur (her ikisi için p<0.0001). Çürüksüz dişlerde tedaviden 6 ay sonra DOS total OC hariç bütün parametrelerde düşüş gözlenmiş, aynı zamanda OHİ-S skorunda
“orta” seviyesinden “iyi” seviyesine değişim görülmüştür.
Sonuç. Bu çalışmada tüm parametreler çürüklü dişlerde periodontitise benzer bulgular sergilerken, çürüksüz
dişler başlarda gingivitis bulguları sergilemiştir.
Anahtar Kelimeler: Ara yüz çürüğü, DOS IL-1β, Osteokalsin, VEGF

ÇOCUKLARDA OBEZİTE VE DİŞ ÇÜRÜĞÜ İLİŞKİSİ
Salih DOĞAN, Erciyes Üniversitesi - Cocuk Diş Hekimliği,
Kevser KOLCAKOGLU, Erciyes Üniversitesi - Çocuk Diş Hekimliği,
Ferhan ELMALI, Erciyes Üniversitesi - Çocuk Diş Hekimliği,
Amaç: Çocuklarda diş çürüğü görülme sıklığının çocuğun beslenme alışkanlıkları ile ilişkili olduğu bilinmektedir. Bu noktadan yola çıkarak yapılan çalışmalarda çocukların beslenme alışkanlığını yansıtan obezite
durumu ile çocuğun genel sağlığı, dolayısı ile de diş çürüğü arasında da bir ilişki olabileceği düşünülmüştür.
Ancak günümüze kadar yapılan çalışmalar çocukluk dönemi obezitesi ve diş çürüğü arasında kesin bir ilişkinin mevcudiyetini kanıtlayamamaktadır. Buna göre; çalışmamızda Kayseri ili bölgesine özel olarak verilen
beden kütle indeksi (BMI) ile WHO BMI değerleri kullanılarak bu bölgede yaşayan çocuklarda obezite ile diş
çürüğü arasındaki ilişkiyi süt, karma ve daimi dentisyondaki sağlıklı ve sistemik rahatsızlığı bulunan çocuklarda ayrı ayrı değerlendirmeyi amaçladık.
Yöntem: Çalışmamızda Erciyes Üniversitesi Diş Hekimliği Fakültesi Pedodonti Anabilim Dalı’na başvuran
ve Kayseri ili bölgesinde yaşayan 3-15 yaş grubu 4558 çocuğun muayeneleri WHO kriterlerine göre yapılmış
olup, BMI ile DMFT ve dmft değerleri hesaplanmıştır. Hastalar yaş, cinsiyet, dentisyon, BMI, DMFT ve dmft
ve de sistemik hastalık açısından incelenmiş ve karşılaştırılmıştır. İstatistiksel analizde ise; pearson ki kare
testi ile T testi kullanılmıştır.
Bulgular: Çalışma sonucunda; sağlıklı çocuklarda daimi dişlenmede BMI indeks değeri ile çürük prevelansı
arasında istatistiksel olarak anlamlı bir farklılık gözlenmiş olup, bu farklılık süt ve karışık dişlenme döneminde anlamlı düzeyde bulunmamıştır. Sistemik rahatsızlığı bulunan çocuklarda ise tüm dentisyon tiplerinde BMI
indeksi ile çürük prevelansı arasında bir ilişki bulunmamaktadır.
Sonuç: BMI indeksinin özellikle daimi dişlenme dönemindeki çocuklarda önemli bir risk faktörü olarak göz
önüne alınması gerekmektedir.
Anahtar Kelimeler: obezite, BMI, diş çürüğü, kayseri, çocuk
