Öğe A diagnosis and treatment of the multiple compound odontoma in mandibula(2009) Sezgin Bolgul B.; Gorgun B.; Ozer T.; Celenk S.; Ayna B.; Atakul F.Odontomas are classified as odontogenic tumours: however, they are thought to be developmental anomalies in which all dental tissues are represented. Compound odontomas are the most common type of odontogenic tumours and generally they are asymptomatic. The occurence of odontoma in the primary dentition is also uncommon. This paper, describes a case of compound odontomas diagnosed in 9 years old male child who presented to the Dicle University Dental Faculty Pediatric clinic complaining about unerupted teeth.Öğe Evaluation of clinical and microbiological features of deep carious lesions in primary molars(2003) Ayna B.; Çelenk S.; Atakul F.; Sezgin B.; Özekinci T.Purpose: Concern about the survival of microorganisms in deep carious lesions may often lead to unnecessary exposure of the pulp during excavation. This study evaluated the relationship between microbiological and clinical results of deep carious lesions in primary molars. Methods: Clinical evaluation was performed on 72 deep carious lesions considered to have pulp perforation after traditional excavation. The dentin color and consistency were assessed by means of standardized scales using the technique of Bjorndal et al before restoration. For microbiological examination, dentin samples were taken by a sterile bur and transferred to transport fluid, then plated on tryptic soy agar for growth of total colony forming units. Samples were then transferred on Rogosa SL agar for growth of oral lactobacilli and on mitis salivarius agar for growth of mutans streptococci. Results: The proportion of mutans streptococci, lactobacilli, and total colony forming units increased when the dentin color and consistency increased. However, the proportion of lactobacilli was smaller than diat of mutans streptococci in carious dentin samples. Conclusions: Contrary to expectations, the findings showed that the number of bacteria in carious dentin of primary molars was not significantly excessive.

Eighty caries-free human permanent mandibular premolar teeth, freshly extracted because of periodontal or orthodontic reasons were randomly divided into four groups of 20 teeth each. Core restorations were prepared using these core materials: Group 1: Filtek P60 (3M ESPE, USA), Group 2: Clearfil Photo Core (Kuraray Medical Inc., Japan), Group 3: Miracle Mix (GC Corporation, Japan) and Group 4: Vitremer (3M ESPE, USA). Then were subjected to thermocycling 1.000 times with a dwell time of 30 second at 5 ± 2 °C and 55 ± 2 °C. The teeth were loaded in a Universal Testing Machine (TSTM 02500; Elista Ltd. Şti., Türkiye). All the teeth were loaded until fracture was occured. The fracture force (Newton) was recorded for each specimen. The results obtained were statistically evaluated with ANOVA and Bonferroni corrected Mann Whitney U-tests. Statistically, the mean fracture resistance scores among groups (p<0.001) and values of fracture code between Group 1 and Group 4, were significant. The group of Filtek P60 was found succesfull when the values of fracture resistance were examined.Öğe Multiple root fracture: A case report(2006) Celenk S.; Ayna B.E.; Ayna E.; Bolgul B.S.; Atakul F.An 11-year-old boy was diagnosed with a horizontal root fracture in the maxillary right lateral incisor and a crown fracture in the maxillary right central incisor. This patient was treated endodontically and conservatively. At a follow-up examination 36 months after treatment, the teeth were functionally and esthetically normal. Radiographically, no pathosis was evident in periapical or fracture areas.Öğe The prevelance and etiology of dental trauma among 5-72 months preschool children in South-Eastern Anatolia, Turkey(2009) Tumen E.C.; Adiguzel O.; Kaya S.; Uysal E.; Yavuz I.; Atakul F.The main objective of this study was to assess the epidemiology of traumatic dental injuries to the primary teeth in children from 5 to 72 months, all atendees in 11 public nursery schools in South-Eastern Anatolia, Turkey. A total of 657 children (346 boys and 311 girls) of both sexes participated in the study. Traumatic dental injuries were classified according to the modified classification proposed by Ellis. An interview was carried out by two trained and calibrated examiners, and clinical oral examinations included distribution of dental injuries by age and sex, etiology of dental trauma, prevelance of affected teeth and type of damage. All results were analyzed using the Statistical Package for Social Sciences (SPSS) software, version 15.0. The prevalence of traumatic dental injuries was 5.02%. There was greater involvement of boys (78.8%), of children aged 37-48 months (63.63%) and of the maxillary central incisors (92.68%). Falls were more often the etiology for dental injuries (66.7%). Most children with a traumatic dental injuries experienced traumatic injuries to one tooth (3.81%), while 1.21% had two traumatized teeth and 94.9% had no traumatic dental injuries. The most common crown fracture was in enamel only (65.9%), followed by discoloration teeth (14.6%). The prevalence of dental injuries in Turkish preschool children was very low. The present study findings emphasize the importance of encouraging parents to visit the dentist with their child at an early stage. Moreover, traumatic dental injury is widespread in the population; it has both physical and psychological effects, it is treatable; and, most importantly, it is preventable.
