光固化封闭剂与光固化流体树脂窝沟封闭临床效果评价

目的:比较光固化流体树脂与光固化封闭剂在实施窝沟封闭方面防龋成本及保留率的差异。方法:选择上海市7～10岁儿童256名,口腔内至少有1对第一恒磨牙无龋。每名儿童一侧的恒磨牙用光固化流体树脂进行窝沟封闭,另一侧用传统光固化封闭剂进行窝沟封闭,使用便携式牙科椅吸取唾液,并用棉卷隔湿。使用2种方法操作时记录每个牙封闭所用去的棉卷数和操作时间。1a后,检查2种材料在牙面上的保留情况。所有操作均在学校内施行,检查由2名医师用镰形探针进行,采用SPSS10.0软件包对数据进行统计学分析。结果:使用传统光固化封闭剂进行窝沟封闭操作时间每牙需3.53min,而光固化流体树脂组需3.32min(P<0.05)。在封闭剂的保留率方面,光固化流体树脂组显著高于传统的窝沟封闭组(P<0.05)。结论:应用光固化流体树脂进行窝沟封闭,能用较短操作时间达到防龋目的,适合在学校推广应用。

Clinical evaluation of pit and fissure sealant with light-cured flowable resin and light-cured pit and fissure sealants

PURPOSE: To evaluate the difference between light-cured flowable resin and light-cured pit and fissure sealant in the cost and retention rate of pit and fissure sealant treatment.METHODS: Two hundred and fifty six children aged from 7 to 10 years were selected in this study.Each of them had at least two caries-free first molars.One first molar was sealed with light-cured flowable resin and the other one was sealed with traditional light-cured sealant.The portable dental chair were used to absorb saliva and ...
