To evaluate the effect of a 2-year oral health education and caries prevention program implemented in kindergartens in China.
Seven hundred and thirty-one 3-year-old children were recruited from 10 kindergartens in Miyun County, Beijing, China. The kindergartens were randomly divided into two groups. Oral health education was provided to teachers in the test kindergartens every 3 months. Oral health education sessions were conducted for the test children monthly and for their parents semiannually. Children in the test kindergarten brushed their teeth twice daily with fluoridated toothpaste (1100 ppm F-) in their kindergarten under the supervision of teachers during weekdays. No oral health education session and no supervised tooth brushing activities were carried out in the control kindergartens. A clinical examination of the study children and a questionnaire survey of their parents were conducted at baseline and after a 2-year program.
Five hundred and fourteen children remained in the study after 2 years. The mean caries increments of the test group (n = 258) and the control group (n = 256) were 2.47 and 3.56 dmfs, respectively. The reduction in dmfs increment was 30.6% (P = 0.009). At the evaluation, a significantly higher percentage of children in the test group than in the control group reported brushing their teeth twice a day (87.6% vs. 69.0%; P < 0.001). Parents of children in the test group had better oral health knowledge and attitude than the parents of children in the control group.
This oral health education program was effective in establishing good oral health habits among preschool children and in increasing oral health knowledge of their parents, in conjunction with supervised daily tooth brushing with fluoridated toothpaste, which could reduce the development of new dental caries in preschool children in China.
评估在中国幼儿园实施的一项为期两年的口腔健康教育与龋齿预防项目的效果。
从中国北京密云县的10所幼儿园招募了731名3岁儿童。这些幼儿园被随机分为两组。对试验组幼儿园的教师每3个月进行一次口腔健康教育。对试验组儿童每月进行一次口腔健康教育课程，对其家长每半年进行一次。试验组幼儿园的儿童在工作日由教师监督，每天用含氟牙膏（1100 ppm F-）刷牙两次。对照组幼儿园不开展口腔健康教育课程和监督刷牙活动。在基线时以及项目开展2年后，对研究儿童进行临床检查并对其家长进行问卷调查。
2年后有514名儿童留在研究中。试验组（n = 258）和对照组（n = 256）的平均龋齿增加数分别为2.47和3.56 dmfs。dmfs增加数的减少率为30.6%（P = 0.009）。在评估时，试验组中报告每天刷牙两次的儿童比例显著高于对照组（87.6%对69.0%；P < 0.001）。试验组儿童的家长比对照组儿童的家长有更好的口腔健康知识和态度。
结合在教师监督下每天用含氟牙膏刷牙，该口腔健康教育项目在学龄前儿童中有效建立了良好的口腔健康习惯，并提高了其家长的口腔健康知识，这可以减少中国学龄前儿童新发龋齿的发生。
