摘　　要：目的比较2种光固化材料用于第一恒磨牙窝沟封闭的临床效果。方法对146名6-10岁患儿采用不同的方法进行窝沟封闭术。在每名学生的双侧下颌第一恒磨牙,随机选择一侧试验组用光固化流体树脂窝沟预防性充填,另一侧对照组用传统窝沟封闭剂封闭,统一由高年资医师操作。在6个月、1年、2年疗效对照分析。结果光固化流体树脂预防性充填在6个月、1年、2年成功率分别为97.89%、95.03%、89.93%;普通窝沟封闭组分别为94.37%、88.65%、75.54%。2年后复查对照组患龋率为7.91%,而试验组患龋率为2.26%,两者有显著差异性（P〈0.05）,说明流体树脂预防性充填更能有效地起到防龋作用。结论光固化流体树脂预防性充填用于预防年轻恒磨牙窝沟龋疗效确切。Objective To compared the clinical effect of two light cured pit and fissure sealants on the permanent molar. Methods Two different methods were applied to Pit and fissure permanent molars in 146 patients aged form 6 to10 years. In the test group,146 permanent molars were treated using flowable resin. In the control group,146 permanent molars were treated using classical Pit-and-fissure sealants. After 6months,1 year,2 years efficacy comparison study was carried out at a same standard respectively. Results The effective rate of the groups with flowable resin to preventive resin restoration were 97. 89%,95. 03% and 89. 93%; The effective rate of the groups with classical Pit-and-fissure sealants were 94. 37%,88. 65% and 75. 54%. There was not significant difference between groups in 6month and1year efficacy,but there was significant difference in 2years. Conclusions Light-cure flowable resin preventive restoration was a reliable permanent molars Pit-and-fissure sealants.
