摘　　要：目的:了解7~9岁儿童第一恒磨牙窝沟封闭剂脱落情况。方法:选择哈尔滨市香坊区符合窝沟封闭适应症的1 074名7~9岁儿童,使用voco封闭剂对第一恒磨牙(2 840个)进行窝沟封闭。术后1年检查窝沟封闭脱落情况,同时对家长进行问卷调查。统计分析儿童年龄、刷牙次数、夜磨牙、饮用碳酸饮料频率、乳牙龋补面数5种因素对窝沟封闭剂脱落的影响。结果:窝沟封闭术后1年,共回收有效问卷883份(2 310个牙),在883人中,窝沟封闭剂部分或完全脱落242人(27.41%);儿童年龄小、刷牙次数少、饮用碳酸饮料频率高、乳牙龋补面数多,其窝沟封闭剂的脱落率高(P<0.05)。结论:7~9岁儿童第一恒磨牙窝沟封闭剂1年脱落率较高,与年龄、刷牙次数、饮用碳酸饮料、乳牙龋补面数有关。AIM： To investigate the related factors of fall off rate of pit and fissure sealant on first permanent molar of 7-to 9-year-old school children in Xiangfang district of Harbin.
