Oral health status of individuals aged 3-80 years in the city of Jönköping, Sweden, has been assessed in a series of epidemiological studies over a 30-year period.
To analyse the changes in caries prevalence and caries distribution in child population sample groups, based on studies performed in 1973, 1978, 1983, 1993, and 2003.
Each time point included 500 randomly sampled individuals, divided into age groups of 3, 5, 10, 15, and 20 years. Results. Thirty-five per cent of 3-year-olds were caries free in 1973, compared with 69% 30 years later. Decayed and filled primary (dfs) and permanent surfaces (DFS) were reduced by 50-80% between 1973 and 2003. Adolescents aged 10 and 15 years exhibited the most pronounced reduction in DFS on the occlusal surfaces. By 2003, 90% of the proximal carious lesions in 15-year-olds were initial carious lesions. In 2003, about 60% of 15-year-olds had a DFS of < or = 5, while about 7% exhibited a DFS of > or = 26.
Despite the dramatic decline in the prevalence of caries, caries remains a health problem among children, particularly those of preschool age. Continuous epidemiological studies are recommended to evaluate preventive measures.
在30年的时间里，瑞典延雪平市开展了一系列流行病学研究，对3至80岁人群的口腔健康状况进行了评估。
基于1973年、1978年、1983年、1993年和2003年进行的研究，分析儿童人群样本组中龋齿患病率和龋齿分布的变化。
每个时间点包括500名随机抽样的个体，分为3岁、5岁、10岁、15岁和20岁年龄组。结果。1973年，35%的3岁儿童无龋齿，30年后这一比例为69%。1973年至2003年间，乳牙龋面均（dfs）和恒牙龋面均（DFS）减少了50%-80%。10岁和15岁青少年的咬合面DFS减少最为明显。到2003年，15岁青少年近中龋损中90%为初期龋损。2003年，约60%的15岁青少年DFS≤5，约7%的青少年DFS≥26。
尽管龋齿患病率大幅下降，但龋齿仍是儿童尤其是学龄前儿童的健康问题。建议持续开展流行病学研究以评估预防措施。
