Between 1987 and 1989, a random sample of school children aged 7 and 12 years in Switzerland was drawn. In the first stage, districts were chosen. Within the districts, 12 children in the two specified age groups were selected. In addition, Switzerland was subdivided into two strata. The children of stratum 2 had consumed fluoridated salt since birth while those of stratum 1 had only done so during the preceding 4 to 5 years but had benefitted since the age of 5 to 7 from dental health education programs using fluorides at school. The oral examinations were carried out according to the methodology of the World Health Organization. Attendance was 94% (1115 children). 47% of the seven-year-old children were caries-free, and the average dmft was 2.20 (95% confidence limits at 1.87 and 2.52). The average dt was 1.06. These children had an average DMFT of 0.40, with 77% having DMFT = 0. At the age of 12, the average DMFT was 2.03, with confidence limits at 1.73 and 2.33. On average, they had 0.45 DT and 38% of them were caries-free (DMFT = 0). There were only minor differences between the 2 strata. These results agreed well with the data from 6 local surveys carried out during 1987 to 1989. When compared with the majority of European countries, caries experience of Swiss children was fairly low.
1987年至1989年期间，在瑞士随机抽取了7至12岁的在校儿童样本。在第一阶段，选取了一些地区。在这些地区内，挑选了两个特定年龄组的12名儿童。此外，瑞士被划分为两个阶层。第2阶层的儿童从出生起就食用加氟盐，而第1阶层的儿童仅在之前的4至5年食用加氟盐，但从5至7岁起就受益于学校使用氟化物的口腔健康教育项目。口腔检查按照世界卫生组织的方法进行。参与率为94%（1115名儿童）。47%的7岁儿童无龋齿，平均dmft为2.20（95%置信区间为1.87至2.52）。平均dt为1.06。这些儿童的平均DMFT为0.40，77%的儿童DMFT = 0。12岁时，平均DMFT为2.03，置信区间为1.73至2.33。他们平均有0.45颗DT，38%的儿童无龋齿（DMFT = 0）。两个阶层之间只有细微差异。这些结果与1987年至1989年期间进行的6次当地调查数据非常吻合。与大多数欧洲国家相比，瑞士儿童的龋齿发病率相当低。
