Abstract

Abstract: PURPOSE: To retrospectively analyze the clinical characteristics of impacted supernumerary teeth in 115 patients. METHODS: One hundred and fifteen patients with im-pacted supernumerary teeth who were admitted to the Department of Oral and Max-illofacial Surgery of Hefei Stomatological Hospital were selected randomly. The age, sex, number of teeth, location, direction, clinical manifestation, anaes-thesia method and operation time were analyzed retrospectively, T test and Chi-square test were used to determine the statistical differences with SPSS 19.0 software package. RESULTS: Among 115 patients, there were 176 impacted supernu-merary, most of them were in mixed dentition period (66.96%), the sex ratio was 2.29:1, and Most patients (59.1%) had one supernumerary tooth, followed by two supernumerary teeth(33.9%). Most supernumerary teeth were located in the middle of the maxilla (68.2%). Inverted ones were the most common (52.8%). The most common symptoms were delayed eruption, displacement, crowding, torsion and space of the adjacent teeth. 92.2% of patients underwent general anesthesia. The dee-per the locations of impacted supernumerary were, the longer the operation time was. CONCLUSIONS: There are regional characteristics of supernumerary teeth in Hefei City, which can provide a reference for clinical diagnosis and treatment.
