目标.本文回顾性研究了中国南方儿童多生牙的特点和分布情况。研究人群包括208名2 - 16岁的儿童。男性比女性更经常受到影响，比例为3.1：1。在283颗多生牙中，95.0%位于前颌骨，71.5%为圆锥形，70.7%为单侧，29.3%为双侧，47.7%为内翻，16.9%为萌出。诊断和拔除多生牙时的平均年龄分别为7.3 ± 2.7岁（最小年龄为2.1岁）和8.1 ± 2.7岁（最小年龄为4.1岁）。70%的患儿为替牙期，81.3%的患儿在全麻下拔除。根据以往的研究，大多数的多生牙位于上颌前区，圆锥形，并保持未萌出。
Objectives. This was a retrospective study to determine the characteristics and distribution of supernumerary teeth in southern Chinese children.Methods. The study population consisted of 208 children aged from 2 to 16 years.Results. Males were more frequently affected than females in the ratio 3.1: 1. Of the 283 supernumerary teeth, 95.0% were located in the premaxilla, 71.5% were conical, 70.7% were unilateral, 29.3% were bilateral, 47.7% were inverted, and 16.9% were erupted. The mean age at the time of diagnosis and removal of the supernumerary teeth was 7.3 +/- 2.7 years ( the minimum age was 2.1 years) and 8.1 +/- 2.7 years ( the minimum age was 4.1 years), respectively. Seventy percent of the children were in the mixed dentition and 81.3% of the supernumeraries were removed under general anesthesia.Conclusion. In accordance with previous studies, the majority of the supernumerary teeth were located in the premaxillary region, were conical shaped, and remained unerupted.
