氟保护漆与玻璃离子水门汀窝沟封闭剂的防龋效果比较

Clinical evaluation of fluor protector and glass-ionomer cement used as pit and fissure sealant for preventing pit and fissure caries in children

目的:比较氟保护漆与玻璃离子水门汀窝沟封闭剂预防年轻第一恒磨牙窝沟龋的临床效果。方法:622例6～8岁儿童,随机分为3组,A试验组207例、335颗牙;B试验组205例、327颗牙和对照组210例、354颗牙。对A组儿童第一恒磨牙应用氟保护漆,每半年1次,对B组儿童第一恒磨牙应用玻璃离子水门汀窝沟封闭剂,对照组为空白对照。试验期3a,采用SPSS10.0软件包经χ2检验比较3组的龋病发病率。结果:3a后,A、B实验组龋病发生率均低于对照组,有显著差异(P<0.01),而A、B2组龋病发生率无显著性差异。结论:氟保护漆与玻璃离子水门汀窝沟封闭剂均有良好的防龋效果。

PURPOSE： To study the clinical effect of the fluor protector and glass-ionomer cement used as pit and fissure sealant for preventing pit and fissure caries in children. METHODS： 622 health permanent teeth in 6-8 years old children were divided into three groups. Children in the experimental group A （n=207,335 teeth） underwent fluor protector every six months, experimental group B（n=205, 327 teeth） with glass-ionomer cement used as pit and fissure sealant and children in the control group （n=210, 354 teeth） underwent no treatment. The incidence of caries were compared among the three groups using SPSS10.0 software package after 3 years. RESULTS： After 3 years, the incidence of caries in A and B experimental groups were lower than in the control group, the difference was significant （P〈0.01）, but there were no significant difference between group A and group B （P〉0.05）. CONCLUSION： Fluor protector and glassionomer cement used as pit and fissure sealant also have good clinical effect in preventing caries.
