Cross-sectional and longitudinal studies were performed in the community (in this paper changed to city) of Jönköping, Sweden, over a period of 20 years to follow changes in oral health and oral health behaviour. To widen our knowledge about dental health and dental care among the adult population, we expanded the study in 1993 to cover the whole county. The specific aim of the present study was to describe tooth loss (excluding third molars) and periodontal bone level in adult residents of Jönköping County and to compare these two parameters in adults living in the city of Jönköping with the same in adults living in the rest of the county. Random samples of individuals 30, 40, 50, 60, and 70 years old were selected. A total of 484 persons from the city and 1219 subjects from the rest of the county were examined. A total of 32 (7%) and 27 (2%) persons were completely edentulous in the examined populations from the city and from the rest of the county, respectively. A majority belonged to the older age groups, 60 and 70 years, with 17% of the subjects in the city being edentulous compared with 13% in the rest of the county. The mean number of missing teeth in subjects in the city versus subjects in the rest of the county was 0.75/0.95, 1.37/1.60, 3.34/2.43, 6.34/7.40, and 9.95/10.26 in 30-, 40-, 50-, 60-, and 70-year-olds, respectively. Of all the different tooth types, the average number of molars per person decreased the most with increasing age from an average of 7.79/7.83 (city/county) to 3.06/3.09 (city/county) for 30- and 70-year-olds, respectively. The proportion of subjects without molars was higher in the older age groups in both the city and the rest of the county with 4.8/10.7% and 15.6/22.0% of the 60- and 70-year-olds, respectively, lacking molars. In both populations, the mean periodontal bone level decreased with age. It was concluded that no important differences in tooth loss and periodontal health could be seen between the two populations. When organising dental care, dental health administrators could apply the findings from the population in the city to the entire county.
在瑞典延雪平社区（本文中改为城市）进行了为期20年的横断面和纵向研究，以跟踪口腔健康和口腔健康行为的变化。为了拓宽我们对成年人口牙齿健康和牙科护理的了解，我们于1993年扩大了研究范围，涵盖了整个县。本研究的具体目的是描述延雪平县成年居民的牙齿缺失（不包括第三磨牙）和牙周骨水平，并比较延雪平城市成年居民与该县其他地区成年居民的这两个参数。选取了30、40、50、60和70岁的个体随机样本。对来自城市的484人和来自该县其他地区的1219名受试者进行了检查。在来自城市和该县其他地区的受检人群中，分别有32人（7%）和27人（2%）完全无牙。大多数属于年龄较大的组，即60岁和70岁组，城市中17%的受试者无牙，而该县其他地区为13%。城市受试者与该县其他地区受试者的平均缺失牙数在30岁、40岁、50岁、60岁和70岁时分别为0.75/0.95、1.37/1.60、3.34/2.43、6.34/7.40和9.95/10.26。在所有不同的牙齿类型中，随着年龄的增长，每人的磨牙平均数量下降最多，30岁和70岁时分别从平均7.79/7.83（城市/县）降至3.06/3.09（城市/县）。在城市和该县其他地区，年龄较大的组中无磨牙的受试者比例较高，60岁和70岁组中分别有4.8/10.7%和15.6/22.0%的人没有磨牙。在这两个人口中，平均牙周骨水平都随着年龄的增长而下降。得出的结论是，两个人口在牙齿缺失和牙周健康方面没有明显差异。在组织牙科护理时，牙科健康管理人员可以将城市人群的研究结果应用于整个县。
