Of the two random samples studied, the first represented 6--8 year-old residents of a natural high fluoride area (n = 115) and resident of all other areas of Finland (n = 1219). The second sample was representative for 7--9-year-old children participating in public dental care in one Finnish country. Structured questionnaires were used to collect data on social class; caries diagnoses were made by local dentists in municipal dental clinics. Children in the highest social class had the lowest caries experience in both high and low fluoride areas. Differences between middle and lower social class children were small. Fluoride affected caries in the primary dentition similarly in all social classes; in both samples this was shown statistically by nonsignificant interaction between social class and fluoride. In Finland, differences between social classes in caries in the primary dentition cannot be removed solely by implementing water fluoridation.
在研究的两个随机样本中，第一个样本代表天然高氟地区6至8岁的居民（n = 115）以及芬兰所有其他地区的居民（n = 1219）。第二个样本代表芬兰一个郡参加公共牙科保健的7至9岁儿童。使用结构化问卷收集社会阶层数据；龋齿诊断由市政牙科诊所的当地牙医进行。在高氟和低氟地区，社会阶层最高的儿童龋齿发生率最低。中低社会阶层儿童之间的差异较小。在所有社会阶层中，氟对乳牙龋齿的影响相似；在两个样本中，社会阶层与氟之间无显著相互作用在统计学上表明了这一点。在芬兰，仅通过实施水氟化不能消除社会阶层之间乳牙龋齿的差异。
