【摘要】：目的评估儿童窝沟封闭干预的远期效果,为开展儿童龋病的预防提供建议。方法采取分层随机整群抽样的方法分别对干预组与对照组的12岁儿童进行问卷调查与口腔检查。数据采用SPSS19.0进行统计分析。比较龋均差异采用独立样本的t检验,比较正确刷牙率、龋患率、牙龈出血率与牙结石检出率差异采用检验。结果干预组与对照组分别调查了2 321名与2 025名儿童,干预组与对照组正确刷牙率分别为22.58%与24.99%,差异无统计学意义(=3.48,P0.05)。第一恒磨牙龋患率干预组为18.61%,对照组为23.85%,差异有统计学意义(=17.86,P0.001)。干预组恒牙龋患率(28.09%)、全牙列龋患率(34.68%)均低于对照组(31.85%、45.53%),差异均有统计学意义(值分别为7.30与53.14,P0.05),干预组与对照组龋均分别为0.90与0.65,差异有统计学意义(t=5.22,P0.001)。结论儿童窝沟封闭对于预防龋齿发生远期效果明显,但需要持续加强儿童的口腔健康教育。
[Abstract]:Objective to evaluate the long-term effect of sealant intervention in children and provide advice for the prevention of caries in children. Methods by stratified random cluster sampling, 12-year-old children in the intervention group and the control group were investigated by questionnaire and oral examination. The data were analyzed by SPSS19.0. To compare the difference of dental caries with t test of independent sample, the correct rate of brushing teeth, the rate of dental caries, the rate of gingival bleeding and the difference of the detection rate of dental stone were tested. Results 2321 and 2025 children were investigated respectively in the intervention group and the control group. The correct brushing rates of the intervention group and the control group were 22.58% and 24.999.There was no significant difference (P 0.05). The caries rate of the first permanent molar was 18.61 in the intervention group and 23.85in the control group. The difference was statistically significant (P 0.001). The rate of permanent teeth caries (28.09%) and total dentition caries (34.68%) in the intervention group were significantly lower than those in the control group (31.85%, 45.53%), and the difference was statistically significant (7.30 and 53.14%, respectively). The mean caries of the intervention group and the control group were 0.90 and 0.65, respectively (t5.22P0.001). Conclusion the long-term effect on prevention of dental caries in children is obvious, but it is necessary to strengthen the oral health education of children.
