摘　　要：目的评估成都市7~9岁适龄儿童第一恒磨牙牙体健康状况、窝沟封闭1年后的效果,并分析窝沟封闭剂的保留情况及影响其保留率的因素。方法对参与2017年中西部地区儿童口腔疾病综合干预项目的儿童的第一恒磨牙情况进行详细记录,并对可纳入的第一恒磨牙进行窝沟封闭,1年后复查其封闭和患龋情况。采用SPSS 22.0软件卡方检验对结果进行统计分析。结果纳入629名儿童,共计1 877颗牙,窝沟封闭1年后完全保留率为87.75%,第一恒磨牙龋齿检出率为0.96%。其中,46牙窝沟封闭剂保留率为91.61%,36牙为88.25%,16牙为87.69%,26牙为84.40%。26牙的窝沟封闭剂保留率较低,与46牙的差异具有统计学意义(P<0.001)。以所在年级为影响因素分析,三年级儿童第一恒磨牙窝沟封闭剂保留率为89.34%,略高于二年级86.57%,但差异无统计学意义(P=0.071)。结论第一恒磨牙窝沟封闭1年的保留率为87.75%,其中26牙最低,46牙最高,牙位也是窝沟封闭剂保留率的主要影响因素之一。Objective This study aimed to evaluate the health status of children aged 7-9 years in Chengdu City and explore the factors affecting the retention rate of their first permanent molars 1 year after the application of pit and fissure sealants.Methods Detailed examinations were conducted on the first permanent molars of children who participated in the Comprehensive Intervention Program for Children’s Oral Diseases in Central and Western China in 2017.The first permanent molars that met the criteria for pit and fissure sealants were sealed,and the sealant retention and caries were reviewed after 1 year.Results were analysed using chi-square test on SPSS 22.0.Results A total of 1877 teeth were examined among 629 children.The complete retention rate was 87.75%a year after sealing and caries,detection rate of the first molars was 0.96%.Among these teeth,46,36,16 and 26 had 91.61%,88.25%,87.69%and 84.40%retention rates,respectively.The retention rate of 26 teeth was lower than that of 46 teeth,and the difference was statistically significant(P<0.001).When grade of schoolchildren was used as the factor,the retention rate of third grade was 89.34%which was slightly higher than that of second grade at 86.57%,but the difference was not statistically significant(P=0.071).Conclusion The retention rate of 1-year pit and fissure sealants was 87.75%.The 26 teeth showed the lowest retention rate,and 46 teeth had the highest retention rate.Tooth position is one of the main factors affecting the retention rate of pit and fissure sealants.
