广州市12~13岁儿童牙龈炎与恒牙龋患病关系的调查分析

【目的】 探讨儿童牙龈炎与恒牙龋的相关关系,为儿童牙龈炎防治工作提供理论依据。 【方法】 采用多阶段分层整群随机抽样的方法共调查广州市12~13岁儿童1 115人。检查方法和标准参考1997年WHO推荐的《口腔健康调查基本方法》,牙龈炎检查六颗指数牙,龋病检查全口恒牙,分别采用牙龈指数(GI)和DMFT记录检查结果。Logistic回归分析儿童牙龈炎与恒牙龋病的关系。 【结果】 广州市12~13岁儿童牙龈炎患病率72.65%,中、重度牙龈炎患病率分别为28.16%和5.83%。恒牙龋患病率为25.83%,其中未充填龋占龋齿的73.73%。Logistic回归分析显示未充填龋是广州市12~13岁儿童牙龈炎患病的危险因素。 【结论】 广州市12~13岁儿童牙龈炎患病率较高,有未充填龋存在的儿童是广州市儿童牙龈炎重点防治人群。
