摘　　要：目的调查河南省儿童口腔疾病综合干预项目实施3年后窝沟封闭剂的保留率及患龋状况,为评价项目的实施效果提供参考。方法随机抽取河南省5个参与2015年儿童口腔疾病综合干预项目的地区,每个地区随机抽取4所学校,每所学校随机抽取二年级2个班。2所学校纳入试验组,对符合窝沟封闭适应证的第一恒磨牙进行封闭;另2所学校纳入对照组,对符合窝沟封闭适应证的第一恒磨牙不进行封闭。3年后复查第一恒磨牙的窝沟封闭剂保留率及患龋情况并进行统计分析。结果窝沟封闭3年后,第一恒磨牙封闭剂完全保留率为65.55%,保留率为94.78%。试验组第一恒磨牙龋病发病率和龋均分为9.71%、(0.12±0.40),对照组分别为21.90%、(0.39±0.78),差异均有统计学意义(χ~2/t值分别为27.76,6.91,P值均<0.01)。窝沟封闭的龋降低相对有效率为63.43%,龋降低实际有效率为6.51%,纯收益率为12.19%。封闭剂的保留率越高,患龋率越低(χ~2=153.28,P<0.01)。结论河南省儿童口腔疾病干预项目的实施效果良好,儿童第一恒磨牙窝沟封闭可有效预防窝沟龋。Objective To examine the retention rate and caries prevention effect of fit-and-fissure sealants after 3 years of children oral disease comprehensive intervention program in Henan province.Methods For each of the five provincial regions attending the program in 2015,two classes from grade 2 in four primary schools were selected.Children in two schools were assigned into intervention group and the first permanent molars which were appriopriate for sealing were sealed with pit-and-fissure sealants.Children in other two schools were included in the control group and the first permanent molars were only examined for caries conditions.Three years later,retention rate of pit-and-fissure sealants and the dental caries prevalence was compared.Results Complete retention rate of sealants in the first permanent molars was 65.55%and the whole retention rate was 94.78%.The caries incidence and mean value of the first permanent molars in the intervention group children was 9.71%,(0.12±0.40)respectively whereas those in control group was 21.90%,(0.39±0.78)respectively.The differences between two groups were statistically significant(χ~2/t=27.76,6.91,P<0.01).The relatively effective rate of sealing for caries reduction was 63.43%and the actural effective rate was 6.51%and the pure yield rate of sealing was 12.19%.Higher sealant retention rate was associated caries prevalence(χ~2=153.28,P<0.01).Conclusion Childhood oral disease intervention project in Henan Province shows positive effects.Sealing of the first permanent molars effectively prevent dental pit and fissure caries.
