摘　　要：目的:评价不同牙面处理方法对第一恒磨牙窝沟封闭剂脱落率的影响。方法:选择我市参加窝沟封闭公益项目的180名1~2年级、7~9岁的学龄儿童共计720个第一恒磨牙,随机分为2组(n=90),分别采用橡皮杯、小毛刷清洁牙面,用Clinpro、Fissurit F、Helioseal F 3种含氟封闭剂进行窝沟封闭(n=30)。每个第一恒磨牙用一种窝沟封闭剂进行封闭;分别于窝沟封闭后3、6个月复查封闭剂脱落情况,并比较各组封闭剂脱落率。结果:在清洁方法相同时,窝沟封闭术后3个月, 3种封闭剂脱落率相比无统计学差异(P>0.05);术后6个月,Helioseal F脱落率均低于Fissurit F和Clinpro(P<0.05)。在封闭剂相同时,术后3、6个月封闭剂脱落率均为刷组低于杯组(P<0.05)。结论:在第一恒磨牙窝沟封闭过程中使用小毛刷清洁牙面比橡皮杯更有优势;Helioseal F封闭剂可有效降低第一恒磨牙窝沟封闭脱落率。Objective: To observe the effect of different tooth surface treatment methods on the rate of pit and fissure sealant expulsion in first permanent molars. Methods: 180 school children aged 7 to 9 years old participated in a free pit and fissure sealing public welfare project. The children were randomly divided into rubber cup group(n=90) and brush group(n=90) for tooth cleaning. The 720 first permanent molars in both groups were sealed with Clinpro, Fissurit F and Helioseal F respectively(n=30). The sealant expulsion was reviewed and the sealant expulsion rate was compared 3 and 6 months after treatment. Results: When the cleaning method was the same, 3 months after treatment, there was no significant difference among the 3 sealants(P>0.05), 6 months after treatment, the expulsion rate of Helioseal F was lower than that of Fissurit F and Clinpro(P<0.05). When the sealant was the same, the expulsion rate in the brush group was lower than that in the rubber cup group(P<0.05). When the sealant was the same, the expulsion rate of the sealant in the brush group was lower than that of the sealant in the rubber cup group(P<0.05). 3 and 3 months after treatment. Conclusion: The use of small brush to clean the tooth surface is more effective than rubber cup in the process of the first permanent molar pit and fissure sealing. The sealant of Helioseal F can reduce the expulsion rate of the first permanent molar pit and fissure sealant.
