摘要：

目的 评价不同酸蚀方法应用于窝沟封闭术的临床效果。方法 选取2011年9月至2012 年3月在佛山市禅城区口腔医院就诊的6 ~ 8岁儿童90例作为研究对象（共240颗第一恒磨牙），随机分为3组，每组30例。分别采用自酸蚀黏结剂（A组）、窝沟釉质成形术结合自酸蚀黏结剂（B组）以及磷酸酸蚀剂（C组）处理牙面后行窝沟封闭术，术后随诊3、6和12个月，比较3种方法的临床效果。结果 在术后3个月和6个月时，3组的窝沟封闭剂保留率和患龋率差异均无统计学意义（均P > 0.05）。术后12个月时，A组的窝沟封闭剂保留率最低，患龋率最高，与其他两组的差异均有统计学意义（均P < 0.05）；但B组与C组间差异无统计学意义（P > 0.05）。结论 自酸蚀黏结剂法行窝沟封闭术的效果不及磷酸酸蚀法，结合使用窝沟釉质成形术可提高窝沟封闭的临床效果。磷酸酸蚀法与窝沟釉质成形术结合自酸蚀黏结剂法的效果相当。

Abstract:

Abstract：Objective To observe the clinical effect of pit and fissure sealant with different clinical acid etching technique. Methods Totally 240 permanent first molars in children aged 6-8 years old were randomly divided into three groups. Group A：self-etching adhesive；Group B：EST with self-etching adhesive；Group C：phosphoric acid. All the children were followed up and reexamined after 3，6 and 12 months. Results The retention rates of pit and fissure sealant and the prevalence rates of caries in three groups had no significant difference after 3 and 6 months（P > 0.05）. At 12th month，the retention rate of pit and fissure sealant in self-etching adhesive group was statistically lower than than in the other groups（P < 0.05），and the prevalence rate of caries was statistically higher than that in the others（P < 0.05）. But the other two groups had no significant difference in the retention rate of pit and fissure sealant and the prevalence rate of caries（P > 0.05）. Conclusion The clinical effect of pit and fissure sealant with self-etching adhesive is worse than with phosphoric acid，but it can be improved by combining enameloplasty sealant technique. The effect of phosphoric acid and EST combination self-etching adhesive are the same.

Key words: pit and fissure sealant, self-etching adhesive, enameloplasty sealant technique
