Salivary secretion and drug treatment in four 70-year-old Swedish cohorts during a period of 30 years.

Objective: The aim was to examine the association between drug treatment and unstimulated and stimulated whole saliva in four 70-year-old Swedish cohorts, between 1971 and 2001.

Background: Both diseases and their medication can affect the salivary secretion rate.

Materials And Methods: The study was based on selected samples of four cohorts born in 1901/1902, 1906/1907, 1911/1912 and 1930/1931, respectively, a total of 1072 individuals.

Prevalence and incidence of dental caries and related risk factors in 70- to 76-year-olds.

Objective: The prevalence of caries and various risk factors was studied cross-sectionally in two cohorts of 72-year-olds over the course of 20 years. Incidence was also studied over a period of 6 years.

Material And Methods: Samples of two dentate subjects from cohorts of 70 to 72-year-olds were included; cohort III (n=135), born 1911-12, and cohort VI (n=139), born 1930.

Secular trends of dental status in five 70-year-old cohorts between 1971 and 2001.

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.
