【摘要】：目的了解广州市适龄儿童第一恒磨牙免费窝沟封闭项目实施2~3年后的质量情况。方法采用随机抽样的方法,分别抽取接受第一恒磨牙窝沟封闭2年后、3年后的儿童各5 576和4 857人,进行窝沟封闭剂保留和龋患情况调查。结果第一恒磨牙窝沟封闭2年后的封闭剂保留率为75.34%、完好率为42.93%,龋齿检出率为5.67%;封闭3年后的封闭剂保留率为72.15%、完好率为37.29%,龋齿检出率为7.04%。城市儿童在封闭2年及3年后封闭剂保留率均高于同期封闭的乡村儿童,差异有统计学意义(2年后的χ~2=38.04、P0.001;3年后的χ~2=4.52,P0.05);下颌牙在封闭2年及3年后封闭剂完好率均高于同期封闭的上颌牙,差异有统计学意义,(2年后的χ~2=40.60、P0.001;3年后的χ~2=15.78,P0.001)。结论广州市适龄儿童第一恒磨牙免费窝沟封闭项目质量基本得到保证,城市封闭质量好于农村,不同牙位封闭质量存在差异。
[Abstract]:Objective to understand the quality of the first permanent molars free of charge closure in Guangzhou after 2 ~ 3 years. Methods A random sampling method was used. After the first permanent molars were closed for 2 years, 5 576 and 4 857 children were selected after 3 years, respectively. Results the retention rate of sealant was 75.34, the perfect rate was 42.933, the rate of caries was 5.67, and the retention rate of sealant was 72.15 and the perfect rate was 72.15 after 3 years. 37.29, the detection rate of dental caries was 7.040.The retention rate of sealant in urban children 2 and 3 years after closure was higher than that in rural children who were closed at the same time. The difference was statistically significant (蠂 2 + 38.04% P 0.001 after 2 years, 蠂 2 + 4.52% P 0.05% 3 years later), and the complete rate of mandibular teeth after 2 and 3 years of closure was higher than that of maxillary teeth sealed at the same time. The difference was statistically significant (蠂 2 + 40.60 P 0.001 after 2 years and 蠂 2 + 15.78% P 0.001 3 years later). Conclusion the quality of free first molars closure in Guangzhou City is basically guaranteed, and the quality of urban closure is better than that in rural areas, and the quality of different tooth positions is different.
