Abstract

INTRODUCTION

Our aim in this study was to investigate the frequency, distribution, sex differences, and characteristics of supernumerary teeth in a referred Turkish population.

METHODS

A total of 2599 patients' panoramic radiographs (1360 girls, 1239 boys) were evaluated, including children in both the mixed and the permanent dentitions. Their mean age was 8.6 +/- 0.23 years. Number, location, classification, side, and impaction of supernumerary teeth were evaluated. Furthermore, the development of these teeth was evaluated.

RESULTS

Eighty-four supernumerary teeth were found on 69 radiographs; 9 were deciduous and 75 were permanent teeth. Most supernumerary teeth were in the premaxillary region (67%). Mesiodens (n = 43) was the most frequent supernumerary tooth (51.2%). This was followed by the maxillary lateral incisor (15.5%), the mandibular premolar (14.3%), the maxillary canine (9.5%), the maxillary premolar (6%), the mandibular lateral incisor (2.4%), and the mandibular canine (1.2%). Sixty-two (73.8%) supernumerary teeth were impacted. The male-female ratio was 1.13:1, which was not statistically significant.

CONCLUSIONS

The prevalence of supernumerary teeth in Turkish children was 2.7% in this study.

摘要

引言

本研究的目的是调查在转诊的土耳其人群中多生牙的发生率、分布、性别差异及特征。

方法

共评估了2599例患者的全景X线片（1360名女孩，1239名男孩），包括处于混合牙列和恒牙列的儿童。他们的平均年龄为8.6±0.23岁。对多生牙的数量、位置、分类、侧别及阻生情况进行了评估。此外，还评估了这些牙齿的发育情况。

结果

在69张X线片上发现了84颗多生牙；其中9颗为乳牙，75颗为恒牙。大多数多生牙位于上颌前部区域（67%）。正中多生牙（n = 43）是最常见的多生牙（51.2%）。其次是上颌侧切牙（15.5%）、下颌前磨牙（14.3%）、上颌尖牙（9.5%）、上颌前磨牙（6%）、下颌侧切牙（2.4%）和下颌尖牙（1.2%）。62颗（73.8%）多生牙发生阻生。男女比例为1.13:1，无统计学意义。
