An epidemiologic study on the prevalence and distribution of dental caries in 16- and 18-yr-olds was carried out in 1987 in the county of Västerbotten, northern Sweden. The subjects had participated in the Public Dental Health Service, including prophylactic programs, since early childhood. The results showed the mean DFS-value to be 5.7 for the 16-yr-olds and 8.1 for the 18-yr-olds. The DFT and DFS-values were higher in the urban than in the rural areas for both age groups, mainly due to more occlusal surfaces being filled in the urban area. Earlier studies have shown a higher prevalence of caries in rural compared to urban areas, explained by a lower socioeconomic level in the rural areas. Although the socioeconomic differences between urban and rural areas persist, the difference in caries prevalence seems to have been eradicated. Both age groups included small subgroups with a high number of DF-surfaces, requiring individualized preventive programs.
1987年，在瑞典北部的韦斯特博滕县开展了一项关于16岁和18岁青少年龋齿患病率及分布情况的流行病学研究。这些受试者从幼儿期就开始参与公共牙科保健服务，包括预防项目。结果显示，16岁青少年的平均DFS值为5.7，18岁青少年为8.1。两个年龄组的城市地区DFT和DFS值均高于农村地区，主要原因是城市地区有更多的咬合面进行了补牙。早期研究表明，农村地区的龋齿患病率高于城市地区，原因是农村地区的社会经济水平较低。尽管城乡之间的社会经济差异依然存在，但龋齿患病率的差异似乎已经消除。两个年龄组中都有一小部分亚组的DF面数量较多，需要个性化的预防方案。
