上海嘉定区不同干预模式对12岁儿童恒牙龋病发生和充填情况的影响

The effects of different interventions on 12-year-old children's permanent teeth caries and filling rate in Shanghai Jiading district

目的:评估不同干预模式对嘉定区12岁儿童恒牙龋病发生和充填情况的影响。方法:将3所中学691名12岁儿童随机分为3组,充填干预组:连续3年免费充填中浅度恒牙龋齿;健康教育组:连续3年进行口腔健康教育;对照组连续3年进行口腔检查。采用SPSS 20.0软件包对数据进行χ2检验。结果:基线时3组的恒牙患龋率分别为32.10%、35.56%和36.84%,恒牙龋齿充填率分别为17.07%、16.24%和17.04%;1年后3组的恒牙患龋率分别为35.92%、42.26%和44.50%,差异无显著性(P>0.05),恒牙龋齿充填率分别为93.28%、61.41%和16.67%,差异显著(P<0.05);3年后3组的恒牙患龋率分别为37.04%、48.12%和58.85%;恒牙龋齿充填率分别为93.66%、61.51%和17.28%,差异均有显著性(P<0.05)。结论:充填干预和健康教育干预均能显著降低12岁儿童恒牙患龋率,提高恒牙龋齿充填率,并且充填干预比健康教育效果更加明显。

PURPOSE： To evaluate the effects of different interventions on 12-year-old children＇s permanent teeth caries and filling rates in Shanghai Jiading District. METHODS： Six hundred and ninety-one 12-year-old children from 3 middle schools were randomly divided into 3 groups. The filling intervention group received filling of the permanent teeth free of charge for 3 years; The health education group received oral health education for 3 years; The control group only accepted oral examination for 3 years. The data was analyzed with SPSS 20.0 software package for x2test. RESULTS： On the baseline, the permanent teeth caries rates of 3 groups were 32.10%, 35.56% and 36.84%, and the filling rates were 17.07%, 16.24% and 17.04%, respectively. After 1 year, permanent teeth caries rates of 3 groups were 35.92%, 42.26% and 44.50%, respectively. There was no significant difference among the 3 groups （/9〉0.05）. The filling rates were 93.28%, 61.41%, and 16.67%, respectively. There was significant difference among the 3 groups （/~〈0.05）. After 3 years, permanent teeth caries rates of 3 groups were 37.04%, 48.12% and 58.85%, and the filling rates were 93.66%, 61.51% and 17.28%, respectively. There were significant differences among the 3 groups （P〈0.05）. CONCLUSIONS： Filling intervention and health education can significantly reduce the permanent teeth caries prevalence rate and improve permanent teeth caries filling rate of 12-year-old children. Furthermore, the effects of filling intervention were more significant than the health education intervention.
