Abstract

Abstract: PURPOSE: To investigate the clinical characteristics of supernumerary teeth in posterior teeth area. METHODS: The data of 119 supernumerary teeth in the posterior teeth area of 55 patients in Stomatology Hospital of Hebei Medical University from June 2014 to May 2020 were analyzed retrospectively from the aspects of the number, position and shape of supernumerary teeth. SPSS 21.0 software package was used for data analysis. RESULTS: Among 55 patients, there were 34 males and 21 females. Twenty-nine cases(52.73%) had one tooth, followed by 11 cases(20.0%) and 8 cases(14.55%) with two and three teeth respectively. Among the 119 supernumerary teeth, 84.87% were located in the premolar region, 57.98% occurred in the mandible, 78.16% were lingual(palatal), 63.02% had a premolar-like shape, 97.48% were in an unerupted state, and 27.73% had an influence on the surrounding teeth. CONCLUSIONS: Female is more than male in the incidence of supernumerary teeth in posterior teeth area. One tooth is the most common, the lower jaw is more than the upper jaw, the lingual (palatal) side is more than the buccal side, the premolar area is more common, the main shape is premolar-like, and some supernumerary teeth will affect the eruption of the surrounding teeth.
