摘要
目的调查沈阳市幼儿园5岁儿童乳牙龋患病情况。方法采用分层等容量随机抽样的方法,抽取沈阳市内5区5岁常住人口440人及其家长,男女各半。检查儿童全口乳牙牙冠龋病情况,统计患龋率、龋均等,将所得数据与本地区1995年的调查数据进行比较;并对家长进行儿童饮食习惯、刷牙情况等的问卷调查。结果乳牙患龋率为67.05%,龋均为3.10,龋齿充填完好率5.51%,曾接受过龋齿治疗的占8.41%。与1995年沈阳市幼儿园5岁儿童乳牙龋病情况比较,患龋率有所下降(P<0.001),龋均亦有下降(P<0.001)。问卷调查中有睡前进甜食行为者占41.28%,定期进行口腔健康检查者只占2.04%,在家长监督下有效刷牙率为10.17%,家长对儿童口腔健康状况满意率为82.91%。结论沈阳市幼儿园5岁儿童乳牙患龋率与1995年相比虽然有所下降,但仍占较高比例。家长对儿童口腔健康认识程度低与高患龋率有关,对家长的口腔健康教育有待加强。
