The prevalence of caries among 3-, 6-, 12- and 19-year-olds in Sweden was followed during the period 1985-1994 through county council reports to the National Board of Health and Welfare. Nearly all the county councils take part in this reporting, and the details for 1994 were based upon 74% of all the country's 12-year-olds and 81% of all the 19-year-olds. Particulars of caries are noted during the annual examination at national dental service clinics. Only manifest caries is recorded. For the age groups studied, the prevalence of caries diminished markedly during the period. The proportion of caries-free 3- and 6-year-olds increased. In 1994, 91% of the 3-year-olds and 64% of the 6-year-olds were free of caries in the deciduous dentition. DFT for 12-year-olds sank from 3.1 to 1.5 during 1985-1994. For 19-year-olds, DFT changed from 8.5 to 5.2, while the proportion of individuals who were caries-free on approximal surfaces increased from 36% to 58%. The change for DFS-a (carious or filled approximal surface) was from 3.4 in 1985 to 1.6 in 1994. These changes in the mean values were accompanied by changes in the frequency distribution of the values for DFT and DFS-a. The proportion of severely carious individuals decreased greatly during the 10-year period studied. At the same time, the differences in caries prevalence among the 26 county councils evened out.
1985年至1994年期间，通过各县议会向国家卫生和福利委员会提交的报告，对瑞典3岁、6岁、12岁和19岁人群的龋齿患病率进行了跟踪调查。几乎所有的县议会都参与了此项报告，1994年的数据基于全国74%的12岁儿童和81%的19岁儿童。龋齿情况在国家牙科服务诊所的年度检查中予以记录。仅记录明显的龋齿。在所研究的年龄组中，这一时期龋齿患病率显著下降。无龋齿的3岁和6岁儿童比例增加。1994年，91%的3岁儿童和64%的6岁儿童乳牙列无龋齿。1985年至1994年期间，12岁儿童的龋失补牙数（DFT）从3.1降至1.5。对于19岁的人群，DFT从8.5变为5.2，而邻面无龋齿个体的比例从36%增至58%。龋失补牙面数-a（龋坏或已充填的邻面）从1985年的3.4变为1994年的1.6。这些平均值的变化伴随着DFT和DFS-a值频率分布的变化。在研究的10年期间重度龋齿个体的比例大幅下降。与此同时，26个县议会之间龋齿患病率的差异也趋于平衡。
