目的：通过对比采用窝沟封闭术(PFS)儿童连续3年窝沟封闭剂留存及其龋齿情况，探讨应用PFS后对预防龋齿的临床疗效。方法：将2009年1月-2010年6月来笔者所在医院进行PFS处理的700名儿童作为本次观察主体，将其第一、二恒牙给予PFS处理，共封闭810颗设其为治疗组；选择其右侧同名健康牙810颗作为对照组，对比治疗组封闭剂留存与两组龋齿情况。结果：治疗组3年后窝沟封闭剂留存率为77.90%，龋齿率为3.14%；对照组3年后龋齿率为9.75%，治疗组龋齿发生率明显较对照组低(P<0.05)。结论：PFS是在恒牙与口腔环境间建立的一道屏障，临床注意其适应证和确保窝沟封闭的严密性，并坚持定期复查，对有效预防龋齿效果明显。

Objective:By comparing the use of pit and fissure sealant(PFS) for three consecutive years child retained its caries pit and fissure sealants,to explore the application of PFS after clinical efficacy in the prevention of dental caries. Method:From January 2009 to June 2010 in our hospital for treatment of 700 cases of PFS children as the subject of this observation,its first and second permanent treatment given PFS were closed 810 set it as the treatment group;The right to choose their namesake healthy teeth 810 as a control group,treatment group compared with two blocking agent retained caries situation. Result:The treatment group three years after the pit and fissure sealant retention rate was 77.90%,dental caries rate of was 3.14%;Control group after 3 years was 9.75%in treatment group than in control of dental caries incidence was significantly lower(P<0.05). Conclusion:PFS in permanent teeth and the oral environment created a barrier between the clinical indications and ensure sealant attention to its rigor,and adhere to regular review,obvious effect on the effective prevention of dental caries.
