摘　　要：目的：分别采用自酸蚀法和磷酸酸蚀法对乳磨牙进行窝沟封闭,观察18个月内窝沟封闭剂保留率和龋病预防情况。方法：选择75例3-4岁幼儿、共计300颗第二乳磨牙,采用自身半口对照方式,随机选择一侧为实验组,使用3M自酸蚀粘接剂进行酸蚀,另一侧为对照组,使用GLUMA酸蚀凝胶酸蚀,行窝沟封闭术,记录操作时间,术后6、12、18个月复查封闭剂的保留情况和患龋情况。结果：实验组1颗牙的封闭时间为（103±10）s,对照组1颗牙的封闭时间为（210±24）s,差异有显著性（P〈0.05）。封闭后6、12、18个月复查,实验组的封闭剂保留率分别为98.67%、97.33%、92.67%,高于对照组的97.33%、96.67%、90%,患龋率分别是0%、0.67%、2.67%,低于对照组的0.67%、1.33%、4%,但无统计学意义。结论：使用自酸蚀粘结剂进行乳磨牙窝沟封闭,可缩短操作时间,降低对患儿依从性的要求,适合临床推广。Objective：To observe the rate of the sealant reservation and caries prevention of pit and fissure sealant on the primary molars etched with self-etching adhesive and phosphoric acid within 18 months.Methods：There were 75 children including 300 second primary molars to be studied.The split mouth design was used in this study.One side of the mouth was randomly chosen for the experiment group using self-etching adhesive way,and the other side using phosphoric acid way was for the control group.Operation time,the sealant reservation rates and the caries condition after 6,12 and 18months were recorded.Results：The operation time for the teeth of the experiment group（103±10s）was statistically shorter than that of control group（210±24s,P〈0.05）.After 6,12and18 months,the retention rates were 98.67%,97.33% and 92.67%in the experiment group,while 97.33%,96.67% and 90%in the control group.The caries rates were 0%,0.67% and 2.67%in the experiment group,while0.67%,1.33% and 4%in the control group.However,there was no significant difference between two groups.Conclusion：The use of self-etching adhesive for primary molar pit and fissure sealant can shorten the operation time,reduce the need of children compliance,and is suitable for clinical application.
