摘要
目的 :观察 4 0 %洗必泰涂料对儿童乳、恒牙防龋作用。方法 :将武汉市 3所幼儿园和 1所小学 12 5 0名 3~7岁儿童随机分为实验组 (洗必泰涂料组 )、阴性对照组 (山达胶涂料组 )和空白对照组 (安慰剂组 ) ,每 6个月分别使用 1次 4 0 %洗必泰涂料、山达胶涂料和安慰剂 ,为期 2年。结果 :实验 2年后 ,实验组与空白对照组相比 ,3岁儿童乳牙新生龋面均降低 4 5 .5 %、5岁儿童乳磨牙新生龋面均降低 4 4 .80 %、6~ 7岁儿童恒牙新生龋面均降低 4 0 .4 2 % ,在统计学上差异有显著意义 (P <0 .0 5 )。而阴性对照组与空白对照组之间的新生龋面均在统计学上差异无显著意义 (P >0 .0 5 )。结论 :4 0 %洗必泰涂料对儿童的乳。
Objective:The purpose of this study was to assess the preventive effects of 40% Chlorhexidine (CHX) varnish on dental caries.Methods:1250 children aged 3~7-year-old from 3 kindergartens and one school were assigned to a CHX varnish group, a Sandarach and a control group. In the CHX varnish group and in the Sandarach group,all children received a 40% CHX varnish application and Sandarach varnish application every 6 months respectively.The study was followed up for two years.Results:A statistically caries-reducing effect on dental caries in primary teeth and permanent teeth was found in the CHX varnish group, the reduction rate of dental caries was 45.5%, 44.80% and 40.42% respectively in three age groups, compared to the data of the control group. There is not significant difference between the Sandarach group and the control group (P>0.05).Conclusions:Six-monthly application of 40% CHX varnish has caries-reducing effect on dental caries in primary teeth and permanent teeth.
