EPI-Norr 1991, 2001 and 2011 are three cross-sectional studies based on surveys, in combination with clinical examination of randomly selected individuals in different age groups in Norrbotten.
In 1991, the study included 35-, 50- and 65-year-olds, and was in 2001 supplemented with 75-year-olds and in 2011 with 85-year-olds in order to be able to follow the health development in the groups over time. In all three sub-studies, approximately 10 percent of the population in the age groups was invited to participate.
With the invitation the questionnaire was delivered and later a reminder. Those who did not answer the questionnaire during the survey instead answered the questions orally. A limited number of pre-calibrated dental care teams who travelled around the county has conducted the clinical trials.
The material contains information on the subjects' answers to questions about health, perceived mouth and teeth problems, experiences of dental care and treatment, and clinical trial data. There are also data from a healthcare assessment that took into account the individual's wishes to take care
