Abstract

Abstract:

Objective To analyze the radiographic characterizations of the supernumerary tooth(ST)in the anterior maxillary region using cone-beam computed tomography(CBCT), in order to help clinicians treat ST. Methods CBCT data of 805 patients were selected. The radiographic characterizations of the ST were evaluated using NNT software, including the number, morphology, location, orientation, growth condition and associated clinical complications. Gender differences of the radiographic characterizations were analysed. Results Male patients outnumbered females with a gender ratio of 2.96∶1. The majority of ST was single, conical shape, palatal, inverted orientation and impacted in both males and females, but the ratio of two ST in males was higher than that in females(P<0.001). Inverted orientation in females was higher than that in males(P<0.001). The most common ST-associated complication was bone resorption of the walls of the nasopalatine canal, and the ratio in males was higher than that in females(P=0.01). In addition, anatomical structures involved by ST and other complications also included bone resorption of nasal floor, odontogenic cyst formation, follicle gap of tooth widen, impaction, malposition, rotation and root resorption of adjacent teeth. Conclusion The majority of ST was single, conical shape, palatal, inverted orientation and impacted in both males and females, but the clinical characterizations between males and females showed significant difference. The presence of ST may produce several complications. The accurate analysis of CBCT scan assists the diagnosis and treatment of ST.
