摘要: 目的:探讨后牙区多生牙的临床特点。方法:回顾2014年6月—2020年5月河北医科大学口腔医院收治的55例患者的119颗后牙区多生牙的临床资料,从多生牙数目、位置、形态等方面进行总结分析。采用SPSS 21.0软件包对数据进行统计学分析。结果:55例患者中,男34例,女21例,男女比1.62:1;1颗多生牙最多,为29例(52.73%),其次为2颗和3颗,分别为11例(20.0%)和8例(14.55%)。119颗多生牙中,84.87%位于前磨牙区,57.98%发生于下颌,78.16%位于舌(腭)侧,63.02%为类前磨牙形,97.48%为未萌出状态,27.73%影响邻近恒牙萌出。结论:后牙区多生牙的发生男性多于女性,1颗最为多见,下颌多于上颌,舌(腭)侧多于颊侧,以前磨牙区多见,主要形态为类前磨牙形,有些多生牙会对周围牙的萌出造成影响。

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.
