An evaluation is made of the epidemiological characteristics of supernumerary teeth, with an analysis of the associated clinical-eruptive complications.
A longitudinal observational study was made of 2000 patients, with the documentation of demographic data, the presence of supernumerary teeth, their location, mechanical accidents and the presence of associated pathology.
The presence of supernumerary teeth was recorded in 1.05% of the study subjects (mean age 20.2 years), with a greater frequency in males. The most frequent location was in the upper maxilla (79.2%), fundamentally in the retromolar zone and at premaxillary level. The presence of mechanical accidents was the most frequent complication (54%)--the displacement of adjacent teeth being the most common finding--along with the presence of follicular cysts.
The prevalence of supernumerary teeth in our series was 1.05%, the most frequent location being at upper distomolar level. Mechanical accidents were the most frequent complication.
对多生牙的流行病学特征进行评估，并分析相关的临床萌出并发症。
对2000例患者进行纵向观察研究，记录人口统计学数据、多生牙的存在情况、其位置、机械性意外及相关病理情况。
在1.05%的研究对象（平均年龄20.2岁）中记录到多生牙的存在，男性发生率更高。最常见的位置在上颌（79.2%），主要位于磨牙后区和前颌水平。机械性意外是最常见的并发症（54%）——相邻牙齿移位是最常见的表现——同时伴有滤泡囊肿。
我们系列研究中多生牙的患病率为1.05%，最常见的位置是上颌远中磨牙水平。机械性意外是最常见的并发症。
