摘　　要：目的：通过比较自酸蚀黏结剂和全酸蚀黏结剂，在流动复合体窝沟封闭中的边缘封闭性和保留率，评价自酸蚀黏结剂在窝沟封闭中应用的效果。方法：选取离体第三恒磨牙40个，采用Dyractflow流动复合体做窝沟封闭材料，分为两组，分别用自酸蚀黏结剂和全酸蚀黏结剂进行封闭处理，体视显微镜下观察封闭剂边缘的微渗漏情况；临床对85名7～10岁小学生采取自身双侧对照研究方法，均采用Dyractflow流动复合体做窝沟封闭材料，随机选择一侧上、下颌第一恒磨牙作为实验组，采用XenoⅢ自酸蚀黏结剂进行窝沟封闭；对侧同名牙作为对照组，采用全酸蚀黏结剂。在第1、2年进行临床观察比较。结果：两种黏结剂均存在微渗漏现象，黏结剂之间的微漏程度无显著性差异（P〉0．05）；临床1、2年保存率均无显著性差异（P〉0．05）。结论：自酸蚀黏结剂在流动复合体窝沟封闭中具有较好的临床治疗效果。AIM ： To evaluate the efficacy of self etch adhesives in Light cure Dyract flow on the pit and fissure sealant technique. METHODS： Forty eight extracted third molars were selected and divided into two groups randomly and treated with Xeno Ⅲ , Prime＆BondNT seperately then restored with Light cure Dyract flow. The first permanent molars with total 340 in 85 children from 7 year to 10 year old were divided into 2 groups randomly. Dyractflow flowable compomer restorative was used as pit and fissure sealant. The experimental group was treated with self etching bonding（Xeno Ⅲ ）, and the control group with total - etching adhesive （Prime＆BondNT）. All children were followed up for one year and two years. RESULTS ： Microleakage was present in two groups. No statistical difference was shown. There was no statistical difference between the two adhesives in the retention of 1 -2 year. CONCLUSION： Self etch adhesives in Light cure Dyract flow for the Pit and fissure sealant technique has good clinical effect.
