摘要

摘要: 目的多生牙是一种因牙齿发育异常导致牙齿数目增多的常见疾病，根据是否伴有全身系统疾病可将其分为综合征性与非综合征性多生牙，前者较罕见。本文探讨非综合征性上颌前牙区多生牙临床特征、影像学表现及治疗方式，为临床诊治及科研提供参考及依据。方法选取2019年1月—2023年6月安徽医科大学附属口腔医院口腔颌面外科收治的上颌前牙区多生牙患者395例，对所有患者个人资料、临床表现、影像学检查、手术方案等进行回顾性分析，应用SPSS 22.0统计学软件对数据进行分析。结果本研究共收集上颌前牙区多生牙患者395例，多生牙551颗。男性患者293例，女性患者102例，男女比例为2.87∶1。患者年龄最小为3岁，最大为45岁。1颗多生牙比例最多，共256例，占比64.81%；患者初次就诊以替牙期最多, 共251例，占比63.54%；多生牙形状以锥型、结节型最多见，共529颗，占比96.01%；多生牙与邻牙轴向关系以倒置型数目最多，共计264颗，占比47.91%；手术以腭侧入路最多，共计292例，占比73.92%。结论非综合征性上颌前牙区多生牙临床多无症状，少数临床表现为牙阻生、牙间隙增宽等；多见于替牙期儿童，男性患者多于女性，高位阻生多生牙最常见，手术常采用腭侧入路。

Abstract: Objective Polydontia is a common disease in which the number of teeth increases due to abnormal tooth development. Clinically, polydontia can be classified into syndromic and non-syndromic types based on whether it is associated with systemic diseases, with the former being rare. This study discusses the clinical characteristics, imaging findings, and treatment methods of non-syndromic polydontia in the anterior maxillary region, providing references and a basis for clinical diagnosis, treatment, and research. Methods A total of 395 patients with polydontia in the anterior maxillary region treated at the Department of Oral and Maxillofacial Surgery of Anhui Medical University Affiliated Stomatological Hospital from January 2019 to June 2023 were selected. Retrospective analysis was conducted on the patients' personal data, clinical manifestations, imaging examinations, surgical plans, etc. Statistical analysis of the data was performed using SPSS 22.0 software. Results This study included 395 patients with polydontia in the anterior maxillary region, totaling 551 supernumerary teeth. The number of male patients was higher than that of female patients, with 293 male patients and 102 female patients, a male-to-female ratio of 2.87∶1. The ages of the patients ranged from 3 to 45 years old. Single supernumerary teeth were the most common, with 256 cases, accounting for 64.81%. Most patients presented during the mixed dentition period, with 251 cases, accounting for 63.54%. The most common shapes of supernumerary teeth were conical and nodular, totaling 529 teeth, accounting for 96.01%. The most common positional relationship with adjacent teeth was inversion, with 264 teeth, accounting for 47.91%. The most common surgical approach was through the palatal side, with 292 cases, accounting for 73.92%. Conclusion Non-syndromic maxillary anterior teeth are asymptomatic, with a few clinical manifestations such as impacted teeth and widened dental space, and are more common in children during their transitional period. Male patients are more common than female patients. High impacted teeth are the most common, and the palatal approach is often used for surgery.
