摘要：

目的 观察0.6%氟化泡沫预防学龄前儿童乳牙龋的效果。方法 2004 — 2006年随机抽取南昌市东湖区3所幼儿园396名4～6岁学龄前儿童为研究对象，将其随机分为试验组（256名）和对照组（140名），应用双盲、安慰剂对照的临床研究方法进行研究，观察两组新生龋面均情况。试验组的儿童每半年应用1次0.6%氟化泡沫，对照组使用安慰剂，观察2年。结果 2年后试验组龋齿降低24.9%，新生龋面均为1.81±0.77，对照组新生龋面均为2.41±0.82，两组对比差异有统计学意义（ P < 0.05）;试验组颊舌面新生龋面均与对照组相比差异有统计学意义（P < 0.05）。结论 0.6%氟化泡沫能够有效预防学龄前儿童乳牙龋的发生。

Abstract:

Objective To observe the effect of 0.6% fluoride foam on preventing dental caries in primary teeth of preschool children. Methods A total of 396 preschool children from 3 kindergartens were randomly assigned into the experimental group and the placebo control group in a double-blind， cluster randomised，placebo-controlled trial. The experimental group received a biannual 0.6% professional application，and the placebo control group received the placebo for 2 years. Results After two rears， the mean caries increment in the experimental group was 1.81 ± 0.77 dmfs while it was 2.41 ± 0.82 dmfs in the placebo control group. The results showed significant difference between the two group（P < 0.05）. There was significant difference in the mean caries increment on occlusal surfaces between the two group （P < 0.05）. Conclusion 0.6% fluoride foam was effective in preventing the increment of dental caries in primary teeth of preschool children.
