氟离子透入预防学龄前儿童龋齿的效果评价

Fluoride ion Penetration into the Prevention of Preschool Childhood Caries Evaluation

目的评价氟离子透入预防学龄前儿童龋齿的效果。方法随机抽取泰州市海陵区12所幼儿园3-4岁儿童共1283名为实验组,另外11所幼儿园3-4岁儿童共1198名为对照组,实验组使用NF-Ⅱ型护齿仪进行氟离子透入防龋治疗,对照组不做任何防龋措施。结果经过3年跟踪调查,实验组儿童每年患龋增长率呈逐年下降的趋势,而对照组儿童呈逐渐升高的趋势。实验组儿童的患龋率、龋均均低于对照组,有显著性差异(X^2=110.36;P<0.005)。结论氟离子透入预防儿童龋齿效果显著,该方法防龋工作效率高,无创伤,安全卫生,避免交叉感染,幼儿易于接受,适宜在幼儿园群体防治。

Objective To evaluate the fluoride ion penetration into the prevention of preschool childhood caries effect.Methods Randomly selected from 12 kindergartens in Taizhou City Hailing a total of 1283 children aged 3-4,called the experimental group,while 11 kindergartens for children aged 3-4,a total of 1198 known as the control group,experimental group using the NF-Ⅱtype teeth instrument for fluoride ion penetration into the anti-caries treatment,the control group without any anti-caries measu. Results After 3 years of follow-up survey,experimental group of children showed an annual growth rate of caries declining trend, while the control group of children was gradually increased trend.The experimental group of children caries rate,DMFT were lower than the control group,there is a significant difference（x2=110.36;P0.005）.Conclusion Fluoride ion penetration marked effect on prevention of child tooth decay,dental caries and high efficiency of the method,no trauma,safety and hygiene,avoiding cross-infection,child care accessible,appropriate control groups in kindergarten.
