Examination of 11-year-old Scots children who had participated in a 5-year, fortnightly dental health education and preventive dentistry programme showed that, compared with a similar age-matched group, the regimen produced mean DMF and DMFS reductions of 48.6% and 42.1%, respectively. In addition, the plaque and gingival indices differed significantly and 22.5% of test children were caries-free compared with only 7.6% of controls.
对参与了一项为期5年、每两周一次的牙齿健康教育和预防牙科项目的11岁苏格兰儿童进行检查后发现，与年龄匹配的类似群体相比，该养生法使平均龋齿、缺失和填充牙面数（DMF）以及龋齿、缺失和填充牙面总和（DMFS）分别减少了48.6%和42.1%。此外，菌斑和牙龈指数存在显著差异，22.5%的受试儿童无龋齿，而对照组只有7.6%无龋齿。
