摘　　要：目的探讨广州市海珠区儿童第一恒磨牙免费窝沟封闭项目(2019)实施3年后的防龋效果,为今后儿童第一恒磨牙窝沟封闭项目的开展和儿童恒牙龋的有效防治提供参考。方法2022年10月,采用随机抽样的方法抽取2019年接受广州市海珠区儿童第一恒磨牙免费窝沟封闭项目的270名广州市海珠区六年级小学生作为封闭组,将符合窝沟封闭条件而没有接受窝沟封闭的同学校、同年龄223名小学生作为对照组,检查以上2组学生的第一恒磨牙,封闭组记录第一恒磨牙封闭剂保留情况和患龋情况,对照组记录第一恒磨牙患龋情况,并与2011年海珠区窝沟封闭项目实施3年后的效果相比较。结果封闭组与对照组相比,患龋率下降(15.56%vs.21.52%,P>0.05),龋齿检出率显著降低(6.12%vs.9.00%,P<0.001),龋均显著下降(0.19 vs.0.37,P<0.001)。相较于2011年海珠区窝沟封闭项目3年后效果:2014年第一恒磨牙封闭剂保留率65.56%,完好率42.25%;第一恒磨牙保护率38.34%;2019年海珠区窝沟封闭项目3年后效果提升:2022年第一恒磨牙封闭剂保留率86.09%(P<0.001),完好率47.00%(P<0.001);第一恒磨牙保护率51.97%。结论2019年广州市海珠区儿童第一恒磨牙窝沟封闭项目的质量较好,降低了龋齿检出率,封闭剂保留率保持在较高水准,但完好率仍未过半,仍需在各年龄段大力推广口腔健康教育及检查,重视窝沟封闭复查和重封闭工作。Objective To investigate the effect of a free pit and fissure sealing program for caries prevention on first permanent molars(six-year molars)in Haizhu District,Guangzhou,three years after its implementation in 2019.The study aims to provide a reference for the future development of pit and fissure sealing programs for children’s first permanent molars and the effective prevention and treatment of permanent tooth caries in children.Methods A random sampling method was used.In 2022 October,270 sixth-grade primary-school students in Haizhu District,Guangzhou,who had participated in the free pit and fissure sealing program for their first permanent molars in 2019,were placed in the sealant group.Another 223 age-matched students from the same schools who met the criteria for the pit and fissure sealing but did not participate in the program were placed in the control group.The first permanent molars of students in both groups were examined.The retention status of the sealant and the caries status of the first permanent molars were recorded for the sealant group,and the caries status of the first permanent molars was recorded for the control group.The 2022 results were compared with the results of a prior pit and fissure sealing program implemented in Haizhu District in 2011,three years after its implementation.Results Compared with the control group,the caries rate in the sealant group decreased(15.56%vs.21.52%,P>0.05),the caries detection rate was significantly lower(6.12%vs.9.00%,P<0.001),and the mean number of decayed teeth was significantly reduced(0.19 vs.0.37,P<0.001).Compared with the results of the pit and fissure sealing program in Haizhu District in 2011(in 2014,the retention rate of the first permanent molar sealant was 65.56%,the intact rate was 42.25%,and the protection rate was 38.34%),the results of the pit and fissure sealing program in Haizhu District in 2019[in 2022,the retention rate of the first permanent molar sealant was 86.09%(P<0.001),the intact rate was 47.00%(P<0.001),and the protection ra
