In cross-sectional studies conducted in 1967, 1971, 1976, 1980, 1987, 1992, 1997 and 2002, 4-year-old children in Umeå, a city in northern Sweden, were examined for dental caries and background factors such as oral hygiene habits, use of fluorides, and sugar consumption. The same methods and criteria have been used in each of the studies from 1967 to 2002. The number of children with caries had declined from 87% in 1967 to 42% in 1987, but then the decline levelled out. In 2002, 46% of the children had caries with a mean dmfs value of 2.0 +/- 3.6. Six percent of the children had 10 or more dmfs. Immigrant children had a higher caries prevalence (p < 0.01). A significant difference in the dmfs values was found in children according to tooth-brushing frequency (p < 0.01). Although the consumption of sugary products between meals increased between 1987 and 1997, no changes were noted from 1997 to 2002. In conclusion, no important changes in caries prevalence have taken place during the last 15 years. The frequency of tooth-brushing and immigrant background had a significant association with caries prevalence.
在1967年、1971年、1976年、1980年、1987年、1992年、1997年和2002年进行的横断面研究中，对瑞典北部城市于默奥的4岁儿童进行了龋齿及口腔卫生习惯、氟化物使用和糖分摄入等背景因素的检查。1967年至2002年的每项研究都采用了相同的方法和标准。患龋儿童的比例已从1967年的87%降至1987年的42%，但随后下降趋于平稳。2002年，46%的儿童患有龋齿，平均dmfs值为2.0±3.6。6%的儿童dmfs值达到或超过10。移民儿童的龋齿患病率更高（p<0.01）。根据刷牙频率不同，儿童的dmfs值存在显著差异（p<0.01）。尽管1987年至1997年间餐间含糖产品的摄入量有所增加，但1997年至2002年未发现变化。总之，在过去15年中龋齿患病率没有发生重大变化。刷牙频率和移民背景与龋齿患病率显著相关。
