Supernumerary teeth occur in both syndromic and nonsyndromic patients, and dental professionals are likely to encounter such teeth in their professional careers. There are three main numbering systems used to identify teeth today: the Universal/ National, the Palmer/Zsigmondy notation, and the Federation Dentaire Internationale (FDI) numbering systems. However, a review of the literature suggests that none of these three consistently addresses the identification of supernumerary teeth. Being able to communicate the location of supernumerary teeth is important for dental professionals, especially in interdisciplinary situations. This article proposes a guideline to locate and identify supernumerary teeth in two and three dimensions, which may reduce treatment errors and improve communication among health care providers and third-party administrators.
额外牙可发生于综合征患者和非综合征患者中，牙科医生在其职业生涯中可能会遇到此类牙齿。目前主要有三种编号系统用于识别牙齿：通用/国际编号系统、Palmer/Zsigmondy 编号系统和国际牙科联合会（FDI）编号系统。然而，文献回顾表明，这三种编号系统都不能始终如一地识别额外牙。牙科医生能够准确地描述额外牙的位置非常重要，尤其是在跨学科的情况下。本文提出了一种二维和三维定位和识别额外牙的方法，这可能会减少治疗错误并改善医疗保健提供者和第三方管理者之间的沟通。
