Abstract :Aim: Teeth that occur in distant places from the alveolar arch insert ignore into journalissuearticles values(maxillary sinus, orbit, infratemporal fossa, condylar region, etc.); because of various local or systemic factors are named heterotopic teeth. The heterotopic tooth is a rare phenomenon. Although the etiology is still unknown, it is known that it may be seen due to pathologies caused by cystic lesions, cleft lip-palate, trauma history, and infectious conditions. They are usually asymptomatic, so they are detected by chance in routine clinical and radiological examinations. This study aims to determine the frequency of heterotopic permanent teeth and their anatomical localization with the help of cone-beam computed tomography insert ignore into journalissuearticles values(CBCT);. Methods: This study was retrospectively performed with CBCT slices. CBCT sections of 2590 individuals insert ignore into journalissuearticles values(1432 females, 1158 males); between the ages of 10-89 insert ignore into journalissuearticles values(mean: 44 ± 17 years); were evaluated in the study. Heterotopic teeth were investigated using coronal, axial, sagittal CBCT sections in regions distant from the maxillary-mandibular arch. SPSS V.21 software insert ignore into journalissuearticles values(IBM Corp., Armonk, NY, USA); was used for data analysis. Results: Heterotopic teeth were found in 10 of 2590 individuals insert ignore into journalissuearticles values(0.4%);. All of the heterotopic teeth detected are molar teeth; 4 are mandibular third molar teeth, 5 are maxillary third molar teeth and 1 is maxillary second molar tooth. The frequency of heterotopic teeth according to gender did not show a statistically significant difference insert ignore into journalissuearticles values(4 females, 6 males); p> 0.05. The average age of individuals with heterotopic teeth is 35.3 insert ignore into journalissuearticles values(17-65 years);. 4 of the heterotopic impacted teeth are located in the ramus and 6 in the maxillary sinus. Conclusions: The prevalence of heterotopic teeth is very rare insert ignore into journalissuearticles values(0.4%);. The teeth with the highest frequency of heterotopia are the third molars. Heterotopic teeth do not have an anatomical location and gender that they prefer predominantly.
