Öğe THE DETAILED EVALUATION OF SUPERNUMERARY TEETH WITH THE AID OF CONE BEAM COMPUTED TOMOGRAPHY(Taylor & Francis Ltd, 2010) Tumen, E. C.; Yavuz, I.; Tumen, D. S.; Hamamci, N.; Berber, G.; Atakul, F.; Uysal, E.The aim of this paper is to demonstrate the application of a recently developed three-dimensional imaging system, cone beam computed tomography, in the detailed evaluation of supernumerary teeth. Two-hundred and twenty three patients with supernumerary teeth (68 females and 155 males) were included in this study. Patients ranged in age from 12 to 25 years. Supernumerary teeth were detected by clinical examination and traditional radiographies. Moreover careful investigation for more details was made with the cone beam computed tomography. Supernumerary teeth which were detected with the examinations of the cone beam computed tomography images were classified according to the number location, shape and eruption rate. The prevalence of supernumerary teeth was determined to be 1.45% of the study population. Males were affected more than females in a ratio of 2.3:1. Supernumerary teeth were most frequently located in 86.2% of the cases in the maxilla; 10.1% in the mandible and 3.7% both in the maxilla and mandible. Supernumerary teeth were most commonly conical in shape (68.8%). One supernumerary tooth was present in 67.7% of the patients, 30.9% had two, and 1.4% had three supernumeraries. Definite and early diagnosis of the supernumerary teeth is very important. Detailed examinations and evaluations of these teeth with three-dimensional images is very benefical in terms of treatment planning and preventing complications which may occurÖğe Incisor trauma in a Turkish preschool population: Prevalence and socio-economic risk factors(F D I World Dental Press Ltd, 2011) Tumen, E. C.; Adiguzel, O.; Kaya, S.; Uysal, E.; Yavuz, I.; Ozdemir, E.; Atakul, F.Objective: This study aimed to assess the prevalence of traumatic injuries of the primary incisors in preschool children from 2 to 5 years old in South-Eastern Anatolia, Turkey. Additionally, the relationship between traumatic dental injuries, parents' education level, family income, size of incisal overjet and the presence of anterior open bite were examined. Basic research design: A cross-sectional survey Clinical settings: Data were collected through oral examinations and structured interviews, and included socio-economic indicators. Participants: A total of 727 children of both genders were included in the study. 122 of these children were aged 2; 183 aged 3; 178 aged 4 and 186 aged 5. Results: The prevalence of dental injuries was 8.0% (n=58). The highest frequency of trauma in the primary teeth was observed at the age of 4. Boys experienced more dental injuries than girls, 12.2% and 4.0%, respectively. The most common crown fracture was in enamel only (57%) followed by crown fracture of enamel and dentin (19%). Conclusion: The prevalence of dental injuries in Turkish preschool children was very low. The children with incisal overjet greater than 5mm and anterior open bite experienced more dental injuries in primary teeth than their counterparts with normal occlusion. Socio-economic indicators were not statistically significantly associated with the occurrence of traumatic dental injuries.Öğe Microleakage of Glass Ionomer based Restorative Materials in Primary Teeth: An In vitro Study(Wolters Kluwer Medknow Publications, 2018) Ayna, B.; Celenk, S.; Atas, O.; Tumen, E. C.; Uysal, E.; Toptanci, I. R.Aim: Using AutoCAD, we examined the microleakage of dye at the edges of primary-teeth restorations using three glass ionomer-based restorative materials. Materials and Methods: A total of 30 extracted noncarious primary molars were used. Class V cavities were adjusted on the buccal surfaces. The teeth were randomly divided into three groups of 10 teeth each as follows: Group A (Ketac Molar), Group B (Photac Fil), and Group C (Dyract XP). All specimens were stored for 24 h at 37 degrees C in distilled water. The teeth were thermocycled 1000 times between 5 degrees C +/- 2 degrees C and 55 degrees C +/- 2 degrees C before immersion in 0.5% basic fuchsin for 24 h. Two mesiodistal cuts of each tooth were photographed under a stereomicroscope equipped with a digital camera. The dye-infiltrated surface area was measured. Statistical evaluations were performed by the Kolmogorov-Smirnov test, Levene test, one-way analysis of variance, and Tukey's honestly significant difference test. Results: The mean microleakage ratio differed significantly among the groups (P < 0.05). Group C exhibited a significantly smaller area (P < 0.001) than the other groups. Group A had a nonsignificantly higher mean microleakage value than Group B (P > 0.05). Conclusions: Polyacid-modified composite resin may be a useful restorative material in primary teeth in terms of minimizing microleakage.Öğe Prevalence of Traumatic Dental Injuries and Associated Factors Among 8 to 12-years-old Schoolchildren in Diyarbakir, Turkey(Wolters Kluwer Medknow Publications, 2017) Tumen, E. C.; Yavuz, I.; Kayd, S.; Uysal, E.; Tumen, D. S.; Ay, Y.; Basaran, G.Background and objectives: This study aimed to assess the prevalence of traumatic injuries of the permanent incisors in public primary schoolchildren from 8 to 12 years old in South-Eastern Anatolia, Turkey. Additionally, the relationship between traumatic dental injuries, parents' education level, family income, size of incisal overjet and the presence of anterior open bite were examined. Materials and methods: Data were collected through oral examinations and structured interviews, and included socio-economic indicators. A total of 2907 children of both genders (1498 boys, 1409 girls) were included in the study. The response rate was 97%. Results: The prevalence of dental injuries was 4.6% (n = 135). The highest frequency of trauma in permanent teeth was observed at the age of 12 (8%). Boys experienced more dental injuries than girls, 5.9% and 3.3% (p = 0.001), respectively. The most commonly reported cause of injuries to the permanent incisors was falls (71.8%), followed by collision with objects or people (17.8%). Maxillary central incisors were the most affected by dental injuries (154, 84.6%). The most common crown fracture was in enamel only (67.58%) followed by crown fracture of enamel and dentin (22.52%). Conclusion: Socio-economic indicators and parents' level of education were not statistically significantly associated with the occurrence of traumatic dental injuries. Factors associated with increased risk of dental injuries in permanent teeth were age, gender, having an incisal overjet greater than 5mm and anterior open bite.Öğe The reliability of microleakage studies using dog and bovine primary teeth instead of human primary teeth(Ariesdue Srl, 2013) Yavuz, I.; Tumen, E. C.; Kaya, C. A.; Dogan, M. S.; Gunay, A.; Unal, M.; Toptanci, I. R.Aim This was to investigate if dental restorations on human, dog and bovine primary teeth are equatable for microleakage analysis, and the respective marginal adaptation deficiency in in vitro conditions. Materials and methods In order to determine the level of microleakage in Class V polyacid-modified composite restorations of human, dog and bovine primary teeth, samples were evaluated by dye-leakage method in sections of the inner area of the restorations. Results We found no leakage in 6 out of 10 (60%) human restorations, in 7 out of 10 (70%) of dog and in 7 out of 10 (70%) of bovine teeth. The levels of dye-microleakage were tested with Kruskal-Wallis one-way variant analysis method. The relative leackage differences were not statistically significant among all species (p>0.05). Conclusion We concluded that dog and bovine primary teeth might be suitable for in vitro studies instead of human ones.
