The aims of this study, which are part of the gerontological and geriatric population studies in Göteborg, Sweden (H70), were to describe cohort differences and trends in dental status and utilization of dental care in 70-year-olds. The study is based on five cohorts examined in 1971/72, 1976/77, 1981/82, 1992/93 and 2000/01 (called cohort I, II, III, V and VI, respectively). The total number of participants was 2290 and varied between 386 and 583 in the different cohorts. The proportion of dentate 70-year-olds changed gradually from 49% in the first to 93% in the last cohort. The mean number of teeth in the dentate 70-year-olds was 14 in cohort I and 21 in cohort VI. The proportion of subjects with 20 or more teeth changed from 13% in cohort I, to 20% in cohort III, and to 65% in cohort VI. In cohort I, 76% of the 70-year-olds had some kind of removable denture; 37% in cohort III, but only 17% in cohort VI. About 20% of all 70-year-olds in cohort I reported regular yearly visits to a dentist. The corresponding figures in cohort III and cohort VI were 50% and 80%, respectively. Even though positive cohort trends were observed in all studied subgroups, factors such as low education, smoking, being un-married, having high waist circumference and being physically inactive were negatively associated with dental status at the end of the study period as well as at the beginning.
本研究作为瑞典哥德堡老年学和老年人口研究（H70）的一部分，旨在描述70岁老人牙齿状况及牙科护理利用情况的队列差异和趋势。该研究基于1971/72年、1976/77年、1981/82年、1992/93年和2000/01年检查的五个队列（分别称为队列I、II、III、V和VI）。参与者总数为2290人，不同队列的人数在386至583人之间。有牙的70岁老人比例从第一个队列的49%逐渐变化到最后一个队列的93%。有牙的70岁老人平均牙齿数在队列I中为14颗，在队列VI中为21颗。牙齿数达到或超过20颗的受试者比例从队列I中的13%，变化到队列III中的20%，再到队列VI中的65%。在队列I中，76%的70岁老人佩戴某种可摘义齿；队列III中为37%，但队列VI中仅为17%。队列I中约20%的70岁老人报告每年定期看牙医。队列III和队列VI中的相应数字分别为50%和80%。尽管在所有研究亚组中均观察到队列呈积极趋势，但低教育程度、吸烟、未婚、腰围高和身体不活动等因素在研究期结束时和开始时均与牙齿状况呈负相关。
