目的：多生牙是指在20颗乳牙或32颗恒牙之外，已经萌出或可能萌出的牙齿或牙样结构。患者与方法：本研究回顾了2014年2月至2018年9月在国立成功大学医院全麻下接受手术治疗的患者的病历，分析了其多个SNT的全景X线片和锥体束CT扫描结果，并用描述性统计学方法讨论了治疗方法和相关并发症，特别是异常SNTs。平均年龄12.4岁)共241例，其中1例为SNT，35例为2例，3例为3例，2例为4例，2例为5例，2例为6例，1例为12例。上颌185个，下颌56个；近中牙合153个，内翻115个；无症状142个，圆锥形137个；完全阻生228个，部分阻生210个。2例为上颌窦内神经NTS，1例为5例SNTS合并马凡综合征。两名患者术后有唇或下巴感觉异常，两名患者有术后鼻窦炎。结论：患者人口统计学变量提供了有用的流行病学信息。我们推荐使用全景X线片或锥形束计算机断层扫描来处理可能存在多个SNT的患者以及提取SNT。(C)2018年美国口腔颌面外科医生协会
Purpose: Supernumerary teeth (SNTs) are teeth or tooth-like structures that have erupted or might erupt in addition to the 20 primary or 32 permanent teeth. The simultaneous presentation of multiple SNTs, syndrome-related multiple SNTs, SNTs inside the maxillary sinus and treatment outcomes were analyzed to develop improved diagnosis and management plans.Patients and Methods: This retrospective study reviewed the medical records of National Cheng Kung University Hospital patients who had undergone surgical intervention with general anesthesia between February 2014 and September 2018; analyzed panoramic radiographs and cone beam computed tomography scans of their multiple SNTs; and used descriptive statistics to discuss treatments and relative complications, especially of unusual SNTs.Results: The records of 165 patients (127 male and 38 female patients; mean age, 12.4 years) with 241 SNTs (120 patients had 1 SNT, 35 had 2 SNTs, 3 had 3 SNTs, 2 had 4 SNTs, 2 had 5 SNTs, 2 had 6 SNTs, and 1 had 12 SNTs) were reviewed. There were 185 SNTs in the maxilla and 56 in the mandible; 153 were mesiodens and 115 were inverted; 142 were asymptomatic and 137 were conical; and 228 were fully impacted and 210 were partial roots. Two patients had SNTs inside the maxillary sinus, and one had 5 SNTs and Marfan syndrome. Two patients had postoperative lip or chin paresthesia, and two had postoperative sinusitis.Conclusions: Patient demographic variables provided useful epidemiologic information. We recommend panoramic radiographs or cone beam computed tomography for managing patients with possible multiple SNTs and for extracting SNTs.
