摘要
目的对氟保护漆预防儿童乳牙龋齿的临床效果进行评价。方法将重庆市一所幼儿园的150名3岁儿童随机分为4组,0.5%氟保护漆组、0.1%氟保护漆组、0.5%氟化钠组和空白对照组,分别采用质量分数为0.5%氟保护漆、0.1%氟保护漆、0.5%氟化钠和去离子水作为涂擦药物,每6个月涂擦1次,为期2年,记录试验前后患龋情况,对4组药物的防龋效果进行比较分析。结果0.5%氟保护漆组的龋均和龋面均显著低于0.1%氟保护漆组、0.5%氟化钠组和空白对照组(P<0.05)。结论质量分数为0.5%的氟保护漆具有明显的预防乳牙龋齿的作用。
Objective To evaluate the clinical effect of fluoride varnish in preventing caries of primary teeth, and to compare the caries prevention effects of fluoride varnish with two different concentrations. Methods 150 children whose ages were three year-old were randomly chosen from one of nurseries of Chongqing, and were randomly divided into four groups with 37 children in 0.5% fluoride varnish group, 38 children in 0.1% fluoride varnish group, 39 children in 0.5% sodium fluoride group and 36 children in blank group. The groups included 71 girls and 79 boys. Protective measure was applied every half an year and the research has lasted for two years. The research was designed by double-blinded methods, and was carried out with the dental caries standard suggested by World Health Organization. All the data were collected and the clinical effects of four groups were compared. Resuits The average caries index and caries surface index of 0.1% fluoride varnish group and those of control groups were significantly higher than that of 0.5% fluoride varnish group. There were no significant difference between the average caries index and caries surface index of 0.1% fluoride varnish group and those of control groups. Conclusion 0.5% fluoride varnish was effective in preventing caries of primary teeth.
