Abstract

Abstract

Purpose: The aim of this study wasto evaluate the frequency and type of dental transposition and its relationship with other dental anomalies and pathologies using cone beam computed tomography (CBCT). Materials Methods: Images of patients who had CBCT images taken for various reasons between 2012 and 2023 were evaluated for the occurrence of dental transposition. The demographic data of the patients, the presence of transposed teeth, their number, location, unilateral or bilateral nature, dental transposition classifications defined in the literature, other adjacent dental anomalies and pathologies were examined. Results: CBCT images of 5000 patients were examined, and 42 transposed teeth were found in 39 of the patients (0.78%). It was observedunilaterally in 92.3% of the patientsand bilaterally in 7.7% of the patients. The most common method was maxillary canine-first premolar transposition (47.61%), and the least common was maxillary central-lateral transposition (2.38%). The presence of persistent primary teeth was the highest in the relevant region (61.53%). External root resorption of tooth roots adjacent to transposed teeth was diagnosed in 17.94% of the patients. Conclusion: The prevalence of transposition in Turkish society was 0.78%. This study is the first to examine dental transpositions using CBCT in the Turkish population. External root resorption was observed in a number of the adjacent teeth showing transposition. A detailedCBCT examination is very important for diagnosing malocclusion and other problems that may occur due to transposed teeth.
