摘　　要：目的 了解河南省儿童口腔疾病综合干预项目实施近5年来,儿童第一恒磨牙窝沟封闭剂保留情况及防龋效果。方法 采用分层随机整群抽样,抽取2015-2017年参加过河南省儿童口腔疾病综合干预项目的 7~9岁儿童及同项目区县非项目学校的同年级儿童。共抽取5 330名儿童,项目学校2 715名,非项目学校2 615名。项目学校第一恒磨牙进行过窝沟封闭的儿童为实验组,检查其第一恒磨牙封闭剂保留情况及患龋情况;项目学校与非项目学校未做过窝沟封闭的学生分为A、B、C 3个对照组,检查其第一恒磨牙患龋情况。分别比较不同牙位、不同封闭时间实验组和对照组儿童患龋率及龋病发病率。结果 实验组儿童第一恒磨牙封闭3年、4年、5年后,封闭剂保留率分别为89.75%、84.01%、71.79%,龋病发病率分别为10.23%、13.97%、18.48%,与B对照组比较,龋齿降低率分别为57.79%、49.43%、34.31%;封闭3年、4年、5年后儿童龋病发病率实验组低于A对照组(22.16%、27.70%、29.11%)(P均<0.05)、也低于B对照组(24.24%、27.63%、28.13%)(P均<0.05),而与C对照组(10.81%、11.40%、16.30%)对比差异均无统计学意义(P均>0.05)。结论 河南省适龄儿童第一恒磨牙窝沟封闭防龋效果显著,必须加强项目质量管理,以提高窝沟封闭剂保留率,达到更好的防龋效果。Objective To investigate the retention of sealant in the first permanent molars and the effect of caries prevention during the recent 5 years of the comprehensive intervention project for children's oral diseases in Henan.Methods Children aged 7-9 years who had participated in the comprehensive intervention program for children's oral diseases in Henan from 2015 to 2017 and children of the same grade from non-program schools in the same districts or counties were selected by stratified random cluster sampling.A total of 5330 children were selected,2715 from project schools and 2615 from non-project schools.Children whose first permanent molars were sealed in the project school were treated as the experimental group,and their retention of sealant and caries were examined.The students in the program school and the non-program schol whose permanent molars had not been sealed were divided into A,B and C control groups.The caries of the first permanent molars were examined.The prevalence and caries incidence of caries were compared between the experimental group and the control groups with different dental positions and different sealing time.Results After 3,4 and 5 years,the retention rate of sealant was 89.75%,84.01%,71.79%,and the incidence of caries was 10.23%,13.97%,18.48%,respectively.Compared with B group,the caries reduction rate was 57.79%,49.43%and 34.31%,respectively.The incidence of caries in the experimental group after 3,4 and 5 years was lower than that in the group A(22.16%,27.70%,29.11%)(all P<0.05)and also lower than that in group B(24.24%,27.63%,28.13%)(all P<0.05).There was no significant difference in the incidence of caries between the experimental group and group C(10.81%,11.40%,16.30%)(all P>0.05).Conclusions The effect of pit and furrow sealing on the prevention of caries in the first permanent molars of school-age children in Henan province is remarkable.It is necessary to strengthen the quality management of the project to improve the retention rate of pit and furrow sealant and achieve a be
