Tooth loss among middle-aged adults in the Northern Finland Birth Cohort 1966:associations with tobacco smoking and diabetes
Abstract Oral and general health are linked to each other, and both are contributed by many sociodemographic and behavioral factors. Information on tooth loss, as a simple indicator of oral health of an individual, can easily be collected through self-report for research purposes in population studi...
