Dental anxiety in 18-year-old Norwegians in 1996 and 2016.

To estimate the prevalence of dental anxiety, and to explore factors that may increase the risk of reporting dental anxiety among 18-year-old Norwegians in 2016. A further objective was to report changes in dental anxiety since 1996. An anonymous survey from a strategic sample of upper secondary students ( = 351) in 2016 with high response rate (93%) was compared with the results of an investigation of a similar population conducted in 1996. The prevalence of dental anxiety and dental distrust was reduced from 1996 to 2016. Dental Fear Survey (DFS) from 19 to 8% ( < .001), and Dental Belief Survey (DBS) from 15 to 6% ( < .001). Geer Fear Scale (GFS) which measure phobic anxiety did not show a similar reduction (17 versus 15%,  = .37). Phobic anxiety, avoidance behaviour, self-reported poor oral health and previous experiences of pain were all associated with dental anxiety. The prevalence of dental anxiety was reduced from 1996 to 2016, but 8% still report dental anxiety. Proper pain management and use of behavioural management techniques still needs to be highlighted to prevent development of dental anxiety, avoidance behaviour and poor oral health.
