In spite of having a high socioeconomic standing, in Iceland caries prevalence has remained stubbornly high. This study reports findings from a mixed fishing and farming community in East Iceland that has traditionally been associated with the highest prevalence of caries. A total of 188 children aged 3-16 yr (96.4% of residents of that age group) were examined. At 6 yr the mean dmfs score was 4.1, DMFS 0 and 48% were caries-free. The mean DMFS score at 12 yr was 4.7 and 22.6% remained caries-free but at 16 yr the DMFS score was 11.6 and no children were caries-free. Caries was unevenly distributed within each age group and was more prevalent among residents of the fishing town than the surrounding farming district. In a pilot study conducted in 1989 mean counts of Streptococcus mutans for children aged 4-7 yr were 2.6 x 10(5) cfu/ml and declined to 4.6 x 10(4) cfu/ml in 1990 after a program of chlorhexidine brushing had been added to the routine caries preventive measures adopted in this community. It may therefore be possible to screen Icelandic children for caries risk and apply preventive measures to those demonstrated to be most in need.
尽管冰岛社会经济地位较高，但该国的龋齿患病率一直居高不下。本研究报告了冰岛东部一个渔业和农业混合社区的调查结果，该社区传统上一直与最高的龋齿患病率相关。共检查了188名3至16岁的儿童（占该年龄组居民的96.4%）。6岁时，平均dmfs得分是4.1，DMFS为0，48%的儿童无龋齿。12岁时平均DMFS得分是4.7，22.6%的儿童仍无龋齿，但16岁时DMFS得分是11.6，没有儿童无龋齿。龋齿在每个年龄组内分布不均，在渔镇居民中比周围农业区更为普遍。在1989年进行的一项试点研究中，4至7岁儿童的变形链球菌平均计数为2.6×10⁵cfu/ml，在该社区常规采用的龋齿预防措施中增加洗必泰刷牙方案后，1990年降至4.6×10⁴cfu/ml。因此，有可能对冰岛儿童进行龋齿风险筛查，并对那些被证明最需要的儿童采取预防措施。
