本试验在幼儿园中采用含氟牙膏刷牙加饮茶的方法,经过1年8个月,观察防龋效果并对这种方法进行评价。选择168名3岁儿童,按班级随机分成3组,分别采用不同的方法。1组使用不含氟的牙膏刷牙,每天早晚各1次。2组使用含氟牙膏刷牙。3组使用含氟牙膏刷牙同时饮0.5％的茶水(含氟0.96ppm)每天200ml。以1组作对照,比较试验前后龋均增长的变化。结果表明,含氟牙膏刷牙加饮茶,龋均下降53.55％。各组试验前后抑制新生龋的比较。结果表明,含氟牙膏刷牙加饮茶抑制新生龋的效果(dft≤1)达81.03％。而使用不含氟牙膏刷牙只有52.23％,统计学处理有高度显著差异(p<0.01)。本研究还对含氟牙膏刷牙加饮茶对儿童的安全性问题进行了分析,证明是安全、简便、有效的防龋方法。
This experiment in kindergarten with fluoride toothpaste brushing plus tea method, after 1 year and 8 months, observe the effect of anti-caries and evaluate this method. A total of 168 3-year-old children were selected and randomly divided into 3 groups according to the class, using different methods. Group 1 used non-fluoride toothpaste to brush their teeth, 1 times a day sooner or later. Group 2 used fluoride toothpaste to brush their teeth. Three groups using fluoride toothpaste while brushing 0.5% of tea (fluoride 0.96ppm) 200ml daily. A group as a control, compared before and after test the growth of caries changes. The results show that fluoride toothpaste brushing plus tea, caries decreased by 53.55%. Comparison of inhibition of neonate caries in each group before and after test. The results showed that fluoride toothpaste brushing plus tea to inhibit neonatal caries (dft ≤ 1) amounted to 81.03%. There was only a significant difference (p <0.01) in the statistical treatment of brushing using only fluoride-free toothpaste with only 52.23%. This study also analyzed the safety of children's teeth with fluoride toothpaste and tea drinking, which proved to be a safe, simple and effective anti-caries method.
