Abstract

Abstract

Objective To summarize the imaging characteristics of odontoma based on detailed discussion of the value of CBCT in the diagnosis and treatment of odontoma, thereby improving the clinical understanding of odontoma. Methods A retrospective study was undertaken on the imaging data of 19 outpatients who were diagnosed as odontoma by CBCT （KavoiCAT 17-19, Germany） in the Department of Stomatology, Yan’an Hospitalof Kunming City between May 2015 and February 2022, from which the age of the patient, thespatial location, the tooth positionand the type of the odontoma were analyzed. Results The age of the 19 patients with odontoma ranged from 8 to 23, including 6 males and 13 females. With respect to the location of odontoma, there were 10 cases in the upper jawand 9 cases in the lower jaw. Alternatively, these consisted of 16 cases in the anterior area, 2 case in the premolar area, and 1 case in the molar area. As to the tooth position of odontoma, there were 4 cases in the central incisor position of maxillary, 3 cases in the lateral incisor position of maxillary, 3 cases in the canine tooth position of maxillary, 1 case in the lateral incisor position of mandibule, 2 cases in the canine tooth positionof mandibule, 1 case in the first premolar tooth position of mandibule, and 5 cases between two adjacent tooth positions. Divided by the occurrence type, there were 14 cases of compound type and 5 cases of complex type （2 case of cystic odontoma）, of which 12 cases were accompanied byimpacted teeth. Conclusions Odontoma are mostly found in adolescents, with commoner occurrence in females. Most of the patientswere found by radiographic examination when clinical symptoms such as irregular dentition, delayed teeth eruption, and pain of the affected area appeared. The rest patients were accidentally discovered during routine radiographic examination. Odontomas were mostly located in the anterior tooth area, usually the canines and incisors and often accompanied by impacted canines and incisors. Compound odontoma are commoner, while cystic odontoma are relatively rare.The wide application of CBCT would be important for comprehensive understanding of the incidence, clinical manifestations and differential diagnosis of odontoma.
