Survey on dental caries prevalence among 3-year-old children in Jing'an District of Shanghai

目的 :分析上海市静安区3岁儿童龋齿患病情况及严重程度,为龋病发病趋势的监测和相关政策的制定提供流行病学依据。方法:采用整群随机抽样方法,调查静安区959例3岁儿童龋齿患病情况。使用SPSS 15.0软件包对数据进行统计学分析。结果:3岁儿童乳牙患龋率为28.05%,男性高于女性(P<0.05);龋均为0.87,男女间无显著差异。总充填率为5.44%,男女间无显著差异。龋齿好发部位以下颌第二乳磨牙最多,其次为上颌乳中切牙和下颌第一乳磨牙,患龋率最低的是下颌乳侧切牙。结论:3岁儿童龋齿患龋高,治疗程度低,应加强对这一人群的口腔保健力度。
