[目的]观察氟化泡沫预防儿童乳牙龋病的效果，为有效开展儿童龋病防治提供依据。[方法]分层随机抽取丽水市的4所幼儿园小班335名儿童为实验组，每年2次应用1．23％氟化泡沫。另抽取4所幼儿园小班268名儿童为对照组，未采取任何干预措施。随访3年，观察两组儿童龋病检出情况、平均患龋均情况，评价防龋效果。[结果]两组儿童的龋病检出率随年龄的增长而增加，对照组3年后增加了34．05％，实验组增加了22．19％。实验组、对照组儿童的龋病检出率分别为55．62％、66．51％，差异有统计学意义（P＜0．05）。实验组3年后平均龋均为3．4±4．38，对照组为4．7±4．80，两组差异有统计学意义（ P＜0．05）。[结论]1．23％氟化泡沫能有效预防儿童乳牙龋病的发生，值得在幼儿园中推广应用。

[Objective] To observe the effect of fluoride foam on dental caries increment in primary teeth, and provide the basis for prevention and control of children's dental caries. [ Methods] Three hundred and thirty-five children were included randomly from junior classes of 4 kindergartens as experi-mental group , and another 268 children from junior classes of another 4 kindergartens as control group .The experimental group used 1.23%fluoride foam twice a year , and the control group did not have any inter-ventions.The two groups of children were followed up for 3 years, and examined for the situation of their caries detection rate and average risk of caries , and for evaluation of the effect of fluoride foam in prevention of children's dental caries . [ Results] Caries detection rate in the two groups increased with age .After 3 years, caries detection rate in control group increased by 34.05%and in experimental group increased by 22. 19%.The use of fluoride foam reduced 10.89%caries disease for experimental group .Caries detection rates were 55.62%in experimental group and 66.51%in control group .The difference in detection rate was sig-nificant between experimental group and control group (P<0.05).Average caries in experimental group was 3.4 ±4.38 after 3 years, and 4.7 ±4.80 in control group.There was a significant difference in average caries between the two groups (P<0.05). [Conclusion] Application of 1.23%fluoride foam was effective in reducing the increment of dental caries in primary teeth , and it is worth promoting in the kindergartens .
