【摘要】 目的调查本市幼儿园小班儿童乳牙龋齿的患病情况及其影响因素。方法采用整群分层抽样的方法,调查本市33家幼托机构3 379名小班儿童乳牙龋齿情况,所有儿童分为龋齿组和非龋齿组,比较两组儿童的家庭环境及家庭牙齿健康教育情况。结果本市幼托机构小班儿童的患龋率为44.03%;无龋齿组的父母抚养、身体健康、母乳喂养、1岁前刷牙、刷牙≥1次/d、检查刷牙效果、父(母)学历中专以上、家庭中等收入以上等情况的比率显著高于龋齿组,差异均有统计学意义(P<0.05)。无龋齿组的饮料≥1次/d、甜点≥1次/d、糖果≥1次/d、牙痛、(牙痛)影响进食、刷牙后进食、含奶嘴睡觉等情况的比率显著低于龋齿组,差异均有统计学意义(P<0.05)。结论本市刚入托儿童乳牙患龋率较高,母乳喂养、早期刷牙、检查刷牙的效果、家长的口腔保健意识对乳牙有保护作用;低收入、低学历、隔代养育、甜品和饮料、含奶瓶入睡则是乳牙发生龋齿的高危因素。患龋儿童的家人存在错误的口腔健康观念,医务工作者应当利用各种渠道做好口腔健康宣教,以降低儿童患龋率。更多还原
