Dental Anomali̇leri̇n Prevelansi: Koni̇ Işinli Bi̇lgi̇sayarli Tomografi̇ Çalişmasi

Abstract

Aim: Dental anomalies are usually detected incidentally on panoramic radiographs taken during routine dental examinations. Incidentally seen anomalies could be seen more clearly in cone-beam computed tomography (CBCT) due to the limitations of two-dimensional radiographs. The aim of this study is to evaluate the localization of dental anomalies in the jaws and gender distribution in patients living in the Western Black Sea region by evaluating the CBCT images previously taken for different reasons retrospectively. Methods: Radiographic data of 207 patients out of 1230 patients who applied to Zonguldak Bülent Ecevit University, Faculty of Dentistry Oral and Maxillofacial Radiology Department and who were requested to have CBCT imaging due to any reasons were included in the research. The distribution of anomalies in CBCT images were scanned retrospectively classified as maxillary - mandibular, unilateral - bilateral, and female-male according to gender. Results: In our study, 105 of 207 patients with dental anomalies were female and 102 were male. An overall of 239 anomalies were detected in 207 patients. The most prevalent dental anomaly in both sexes was determined to be impacted teeth (%46). Considering the localization distribution of the anomalies, the most prevalent anomaly in both the maxilla and mandible was the impacted tooth. Considering the location of the anomalies in the jaws, and anomalies were mostly observed unilaterally (%80). Conclusion: Impacted teeth anomalies were the most prevalent type of dental anomalies in the Turkish subpopulation. CBCT is a very useful method for the detection of dental anomalies, especially root and canal anomalies.
