Dental anxiety, concomitant factors and change in prevalence over 50 years L. Svensson, M. Hakeberg and U. Wide Boman Objective: To analyse the prevalence of Dental Anxiety (DA) in the general adult population of Sweden, to study concomitant factors of DA and also to compare the prevalence of DA in 1962 with that in 2013. Method: The national study for 2013 included 3,500 individuals, randomly selected from the Swedish population. The data sampling was performed as a telephone survey including 38 questions and this report is a selection of those questions with the focus on DA. The national study from 1962 was a face-to-face survey of 1,331 individuals randomly selected from the Swedish population. Both surveys were conducted by the same company. Results: In 2013, severe DA was reported in 4.7%, moderate DA in 4.5%, low DA in 9.8% and no DA in 80.9% of the subjects. Most (72.9%) of the subjects who reported severe DA attended dental care regularly. Important predictive factors of DA were age, gender, education, and self-rated poor oral and general health. The analysis showed a decrease in the prevalence of DA between 1962 and 2013, specifically a change towards more individuals reporting no dental anxiety (38.5% vs. 80.9%) but also smaller proportions of individuals having low and high DA (46.4% vs 9.8% and 15.1% vs 9.2%, respectively).
