摘　　要：目的验证多乐氟防止儿童六龄牙树脂充填后继发龋产生的有效性,降低儿童继发龋的发生率。方法选取2015年1月‐2015年12月来该科就诊的120例患儿为研究对象,所有患儿左右4颗六龄牙均有龋坏,共480颗龋坏的六龄牙,采用自身对照将480颗患齿分为试验组和对照组。试验组为左侧患龋,共240颗,树脂充填后涂布多乐氟,并每3个月复诊一次再次涂布多乐氟,共涂布4次;对照组为右侧患龋,共240颗,树脂充填后不做处理,观察1年后两组患齿继发龋的产生情况。结果 1年后检查,实验组继发龋发生率为5.83%(14/240),低于对照组继发龋发生率的11.25%(27/240)(P<0.05)。结论多乐氟能有效降低六龄牙树脂充填后继发龋的产生,提高治疗效果,推荐临床常规使用。【Objective】To evaluate the clinical effect of duraphat in preventing secondary caries of the first molar teeth after composite resin filling in posterior cavity.【Methods】A total of 120 participants aged 6 to 12 who came to our department from January 2015 to December 2015 were included. There were caries both left side and right side of the first molar teeth. The left side teeth were included in experimental group and the right side teeth were included in control group. After composite resin filling, the teeth of experimental group were applied with duraphat, while control group received no other treatment. Duraphat was applied every 3 months in the experimental group. The occurrence of secondary caries was observed and documented in both experimental and control groups 12 month later.【Results】After a year, the fillings were checked, 14 teeth in the experimental group had secondary caries, and the ratio was 5.83%. Twenty-seven teeth in the control group had secondary caries, and the ratio was 11.25%. There was significant difference between the experimental group and the control group（P〈0.05）.【Conclusion】The duraphat was effective in preventing secondary caries of the first molar teeth. It can be used routinely in clinical practice.
