A 9-year longitudinal study of reported oral problems and dental and periodontal status in 70- and 79-year-old city cohorts in northern Sweden.
Before 1981 no representative studies of oral health in an elderly population in northern Sweden had been presented, and longitudinal studies of oral health in the aging person were in general rare. Thus the aim of this study was to investigate longitudinal changes in oral health in a representative sample of an elderly city population in northern Sweden. Reported oral problems and treatment needs were noted, and dental and periodontal status was registered in clinical examinations. The frequency of reported annual dental visits and of being called by the dentist increased in the younger but not in the older cohort during the 9-year period. In 1990 all the 79- and 88-year-olds with annual visits reported that they were recalled by the dentist. The clinical investigation showed an increasing amount of tooth loss, root caries, and periodontal disease with increasing age. Among dentulous persons 1.7 teeth per subject were lost from 1981 to 1990 in the younger cohort, compared with 2.6 teeth per subject in the older cohort. The number of sound teeth decreased very little in the younger cohort (from 3.44 to 3.34) but more evidently in the older cohort (from 3.47 to 2.65) during the 9-year period. The frequency of surfaces with attachment level > 3 mm increased statistically significantly from 1981 to 1990 in the older cohort. Subjects with annual visits had in general fewer oral problems.
