摘　　要：目的比较河南省城乡12岁儿童龋病的发病状况,评价该群体中高危人群的龋病分布情况。方法等容量、随机抽取河南省六个地市792名12岁儿童进行患龋状况调查,计算DMFT指数(龋、失、补指数)和SIC指数(显著性龋均指数),并对该指数进行统计学分析。结果河南省城乡DMFT指数分别为为0.31和0.23,SIC指数分别为0.94和0.70。城乡儿童龋均比较差异无统计学意义(Z=-1.040,P>0.05),城乡儿童SIC指数比较差异无统计学意义(Z=-1.570,P>0.05)。结论河南省12岁儿童龋病患病率相对较低,但龋病仍广泛存在并存在风险人群;龋充填率低。Objective To study the prevalence of permanent tooth caries among children aged 12 in rural area and urban area in Henan province, and estimate the distribution of high - risk communities. Methods Stratified equivalent random sampling was used in this study. Data from 792 12 - year - old children were used in this analysis, DMFT and SIC were calculated for them. Results For the rural population and the urban population, the mean DMIT was 0. 31 and 0.23 respectively, and the mean SIC was 0. 94 and 0. 70 respectively. Statistically, there are no significant difference between children aged 12 in rural area and urban area in Henan for I）MFT（ Z = - 1. 040, P 〉 0. 05 ） and SIC （Z = - 1. 570, P 〉0. 05）. Conclusion The prevalence of permanent tooth caries among children aged 12 in Henan was low, but high - risk communities were observed and few teeth were filled for caries.
