辽宁省5岁儿童龋病流行病学调查十年对比分析

目的 通过对辽宁省十年间儿童龋病调查的对比分析,了解龋病患病特点及发展趋势,探讨可能的原因及相应的预防措施。方法 按照全国口腔健康流行病学调查的要求,采用WHO口腔健康调查方法分别于1995年和2005年对辽宁省5岁儿童龋病采取了抽样检查。调查结果 采用SPSS13.0软件包进行数据的统计分析。结果 1995年和2005年辽宁省5岁儿童乳牙患龋率分别为89.49%和73.86%;龋均分别为6.77和4.38,经统计学检验,总体上十年间5岁儿童乳牙患龋率和龋均都有显著下降(P<0.01)。除农村地区十年间患龋率无显著性差异外(P>0.05),其它各组乳牙患龋率和龋均十年间均有显著性差异(P<0.05)。龋病充填的构成在十年间呈上升趋势,但变化幅度不大。城乡和男女性别之间5岁儿童恒牙患龋率和龋均则均无显著性差异(P>0.05)。结论 辽宁省5岁儿童患龋率和龋均均明显低于十年前的调查结果 ,但龋齿充填率仍然很低,应加强对学龄前儿童乳牙龋病的防治。
