Nationwide and regional participation in the newly started dental care system, occurrence of caries and proportion of children registered to be in need of restorative treatment during 1974-1979 were studied in 3-5-year-old Finnish children. The data were collected from the annual reports of municipal dental health centers. The mean annual proportion of children participating in the care increased from 27% in 1974 to 71% in 1979. A clear improvement was noticed in each county, especially in areas where the earlier situation was poor. During the study period an average proportion of entirely cariesfree children increased from 24% at the beginning to 57% at the end of the study. The mean annual proportion of children recorded to be in need of restorative care decreased from 61% at the beginning to 32% at the end of the study period. The mean dmft value decreased from 3.7 in 1974 to 1.7 in 1979. A strong inverse relationship existed between the dental health at the beginning of the study period and the extent of changes in dental health during the 6-year-period. Thus regional differences having greatly diminished since the introduction of the public dental care system.
对芬兰3至5岁儿童在1974年至1979年期间全国和地区参与新启动的牙科护理系统的情况、龋齿发生率以及登记需要进行修复治疗的儿童比例进行了研究。数据收集自市牙科保健中心的年度报告。参与护理的儿童年均比例从1974年的27%增至1979年的71%。每个县都有明显改善，尤其是在早期情况较差的地区。在研究期间，完全无龋齿儿童的平均比例从开始时的24%增至研究结束时的57%。记录显示需要修复护理的儿童年均比例从研究开始时的61%降至研究结束时的32%。平均dmft值从1974年的3.7降至1979年的1.7。研究初期的牙齿健康状况与6年期间牙齿健康变化程度之间存在强烈的负相关关系。因此，自公共牙科护理系统引入以来，地区差异已大幅缩小。
