Prevalence of selected dental anomalies in children and adolescents in Turkey

Aim This study aims to evaluate the prevalence of dental anomalies and the tendency of dental anomalies among the teeth in Turkey. Patients and methods This retrospective study was designed on panoramic radiographs of randomly selected 4105 patients that applied to Zonguldak Bulent Ecevit University, Faculty of Dentistry. In the study, nine types of dental anomalies were analyzed statistically on the panoramic radiography images of the patients, including one supernumerary teeth, odontoma, congenitally missing teeth, ectopic eruption, rotation, impacted teeth, fusion, dilaceration, and morphological defects. Results The prevalence of a dental anomaly among all evaluated patients was 26.7%. The most common anomaly was found to be congenital missing teeth with a prevalence of 14.2%. Odontoma was found to be the least common anomaly with a prevalence of 01%. Congenital missing teeth were most frequently observed in the mandibular second premolar. Conclusion The prevalence of dental anomalies in the study population was very high. Nine different anomalies were detected and congenitally missing teeth are the most common developmental dental anomaly in the study. The prevalence of dental anomalies may vary and early diagnosis of dental anomalies is important for treatment planning and success.
