The aim of the present investigation is to report on the trends in the prevalence and severity of dental caries and dental status in an adult Swedish population over a 30-year period (1973-2003). Four cross-sectional epidemiological studies in 1973, 1983, 1993, and 2003 were performed in Jönköping, Sweden.A random sample of individuals aged 20, 30, 40, 50, 60, 70, and 80 years were examined clinically and radiographically, a total of 2521 individals. Diagnostic variables were edentulousness, number of teeth, initial and manifest caries lesions, restorations, fissure sealants, and quality of restorations (secondary caries and overhangs). The percentage of edentulous 40- to 70-year-old individuals decreased during the 30-year period from 16% to 1%. The distribution of individuals by DFS in the age groups 20-50 years showed a gradual shift towards a positively skewed distribution between the years 1973 to 2003. There was a steady decrease in mean number of DFS in the age groups 20-50 years. In the 20-year-olds the mean number of DFS decreased by 72% and for 50-year-olds, by 37%. In conclusion there has been a marked decrease in DFS in adults up to middle age and a marked reduction in edentulousness over a thirty year period. This shows that the decrease in caries levels in children and adolescents is also occurring among adults.
本研究的目的是报告瑞典成年人群体在30年期间（1973 - 2003年）龋齿患病率和严重程度以及牙齿状况的变化趋势。1973年、1983年、1993年和2003年在瑞典延雪平进行了四项横断面流行病学研究。对年龄在20、30、40、50、60、70和80岁的个体进行随机抽样，进行临床和影像学检查，共2521人。诊断变量包括无牙情况、牙齿数量、初始和明显的龋损、修复体、窝沟封闭剂以及修复体质量（继发龋和悬突）。在这30年期间，40至70岁无牙个体的百分比从16%降至1%。20至50岁年龄组按龋失补牙数（DFS）分布情况显示，在1973年至2003年期间逐渐向正偏态分布转变。20至50岁年龄组的平均DFS数量稳步下降。20岁人群的平均DFS数量下降了72%，50岁人群下降了37%。总之，在长达三十年的时间里，中年及以下成年人的DFS显著减少，无牙情况明显减少。这表明儿童和青少年龋齿水平的下降在成年人中也在发生。
