A study was made of the dental health of a group of 8-year-old children studied earlier as 3-, 4- and 5-year-olds, including examination of caries, gingivitis and occlusion, as well as certain data on oral habits and fluoride prophylaxis. Caries was found in 92% of the children. The mean DMFS-value was 3.1 and the mean defs-value 8.8. A statistically significant correlation was demonstrated between caries indices at 3 and 8 years of age in the group as a whole. Children with a defs-value higher than the mean defs-value at the age of 3, had a higher mean DMFS-value at the age of 8 than the rest of the group. Sagittal relationships remained largely unchanged between 3 and 8 years of age, while the number of children with an anterior open bite decreased from 51% to 4% during the same time, probably due to a decrease in sucking habits.
对一组曾在3岁、4岁和5岁时接受过研究的8岁儿童的牙齿健康状况进行了研究，包括龋齿、牙龈炎和咬合情况的检查，以及关于口腔习惯和氟化物预防的某些数据。92%的儿童发现有龋齿。平均DMFS值为3.1，平均defs值为8.8。在整个群体中，3岁和8岁时的龋齿指数之间存在统计学上的显著相关性。3岁时defs值高于平均defs值的儿童，8岁时的平均DMFS值高于该组其他儿童。3岁至8岁期间矢状关系基本保持不变，而同时前牙开合的儿童数量从51%降至4%，这可能是由于吸吮习惯减少所致。
