Dental anxiety and dental attendance among 25-year-olds in Norway: time trends from 1997 to 2007.

Background: So far, there are few studies considering the development of dental anxiety and dental attendance patterns across time in the general population of Norwegian adults.

Method: Random samples of 1,190 and 8,000 25-yr-olds were drawn from the populations of three counties in Western Norway in 1997 and 2007, respectively.
