Sammanfattning

The aim was to study the relationship between dental state, prosthetic rehabilitation and chewing ability in 70-year-old subjects examined between 1971 and 2001. Five birth cohorts born in 1901/1902 (I), 1906/1907 (II), 1911/1912(III), 1922 (V), and 1930 (VI) were examined at 70 years of age. The number of participants in the odontological cohorts varied between 386 and 583. The prevalence of total edentulism changed from 51% in cohort I to 7% in cohort VI. The proportion of subjects using removable dentures decreased from 76% to 17%, whereas those with >or=20 teeth increased from 13% to 65%. The prevalence of subjects with fixed partial dentures increased from 26% to 58%. Of the 70-year-old subjects examined in 2001, 5% had implant-supported restorations. The self-assessed chewing ability showed only weak associations with dental state, and there was no significant cohort trend. When all cohorts were pooled together, 80% considered their chewing ability good, 16% less good and 4% poor. Among the edentulous subjects, more individuals complained about poor chewing ability in the last two cohorts than in the first three. It was concluded that there were great differences in dental state between the five cohorts of 70-year-old subjects examined from 1971 to 2001. Edentulism and wearing of removable dentures decreased substantially, whereas the proportion of subjects with fixed partial dentures showed a marked increase. In spite of the improved dental state, the self-assessed chewing ability exhibited only minor variation over time.
