福建省城乡15岁以上人群乳牙滞留状况抽样调查分析

目的：了解福建省居民乳牙滞留状况及分布规律，为临床滞留乳牙的治疗及口腔健康流行病学抽样调查提供参考。方法：采用多阶段、分层、整群随机抽样的方法调查了15岁、18岁、35～44岁、65～74岁年龄组8528人的乳牙滞留情况。结果：15岁、18岁、35～44岁、65～74岁年龄组乳牙滞留率为1．41％、1．31％、0．38％、0。其中年龄最大为36岁，单人滞留牙最多为4颗，以下颌第二乳磨牙和上颌尖牙最常见。结论：对没有恒牙胚的滞留乳牙，可尽量保存，对有恒牙胚的可拔除滞留乳牙，引导恒牙萌出。在进行口腔健康流行病学抽样调查时应考虑乳牙滞留问题。

There are at most 4 retained deciduous teeth in one single person. And condition is mostly seen at first deciduous molar and maxillary deciduous cuspid.
