摘　　要：目的评价局部涂氟用于学龄儿童第一恒磨牙的防龋效果,为学龄儿童龋病防治提供参考依据。方法选取广西河池市大化县某小学一年级6~7岁儿童378名(1053颗第一恒磨牙),按照随机抽样原则,分为试验组和对照组。试验组191名(542颗第一恒磨牙),对照组187名(511颗第一恒磨牙)。试验组每半年涂布多乐氟1次,同时进行口腔健康教育,共计3次;对照组只进行相同的口腔健康教育。试验开始前检查两组儿童的第一恒磨牙龋患情况,试验18个月后复查。结果试验组与对照组患龋率分别由干预前21.99%增至27.75%,24.60%增至37.43%;干预后发病率分别为5.76%及12.83%。干预后试验组患龋率、发病率、新增龋均、新增龋面均、面患龋率、窝沟龋患龋率、邻面龋患龋率、牙面龋发病率均低于对照组,差异均有统计学意义(P<0.05)。结论局部涂氟能够有效预防第一恒磨牙龋的发生。Objective To investigate the effectiveness of fluoride varnish in preventing first permanent molars cariesinschool-age children and provide necessary information for oral health instruction.Methods378children aged6-7years old in the first grade of primary school in dahua country,hechi city,Guangxi province(1053first permanent molars)were randomly recruited into2groups.The test group(542first permanent molars in191children)was treated with fluoride varnish one time in a half year and given oral hygiene instruction3times;The control group(511first permanent molars in187children)was only given oral hygiene instruction3times.All first permanent molars were checked after18months later for caries.Results After intervention,the caries prevalence rate in the test group raised from21.99%to27.75%compared with the control group from24.60%to37.43%.The caries incidence rate in test and control group was5.76%and12.83%respectively.There was a significant difference between2groups regardless of caries prevalence,car?ies incidence,the DMFT reduction,the DMFs reduction,the occlusal caries prevalence,the pit and fissure caries prevalence,the proximal caries prevalence.Conclusion Semi?annual application of fluoride varnish is effective in the prevention of dental caries in first permanent molars,which was worth of being popularized in clinic.
