摘要

目的:评价多乐氟对学龄前儿童龋病的预防效果。方法:于2013-09选取本辖区幼儿园进入小班儿童322名,分为干预组(n=162)和对照组(n=160),干预组儿童每半年1次涂布多乐氟,并做口腔卫生宣教,对照组儿童仅做口腔卫生宣教,进行3年的队列研究,对比干预效果。结果:2组儿童在3年中的龋均皆持续增高,但干预组的增长速度低于对照组(P<0.05);干预组第2、 3年的龋病发病率和患龋率均低于对照组(P<0.05),干预组儿童在3年中的患龋率与时间存在线性关系(χ~2=26.840,P<0.05),对照组儿童在3年中的龋病发病率,患龋率与时间存在线性关系(χ~2=89.162, 180.482,P<0.05)。结论:周期性应用多乐氟能降低学龄前儿童的龋病发病率和患龋率。
        Objective: To evaluate the preventive effect of Duraphat on dental caries in preschool children. Methods: 322 children enrolled into kindergarten were selected and divided into 2 groups in September 2013. The children in intervention group(n=162) were treated with Duraphat every six months and had oral hygiene education, those in control group(n=160) only had oral hygiene education. The 3-year outcome was compared between 2 groups. Results: The mean DMFT of children in the 2 groups increased continuously in 3 years, but the growth rate of the intervention group was lower than that of the control group(P<0.05). The caries incidence rate and caries prevalence rate of the intervention group were lower than those of the control group in the second and third year(P<0.05).There was a linear relationship between caries prevalence rate and time in the intervention group(χ~2=26.840, P<0.05) in 3 years. There was a linear relationship between caries incidence rate, caries prevalence rate and time in the control group(χ~2=89.162, 180.482, P<0.05) in 3 years. Conclusion: The use of Duraphat can reduce the caries incidence rate and caries prevalence rate in preschool children.
