The prevalence of dental anxiety across previous distressing experiences

Aims

To compare the prevalence of high dental anxiety across a variety of past distressing experiences with a previously reported Dutch sample.

Method

University students from the UK (N = 1024) completed an online survey containing; the Modified Dental Anxiety Scale, and the Level of Exposure-Dental Experiences Questionnaire (LOE-DEQ). Adjusted odds ratios (OR) were calculated to assess the association of self-reported distressing experiences and dental anxiety.

Results

The percentage of respondents with high dental anxiety (HDA) (total MDAS score ≥ 19) was 11.2%. Significant prevalence of HDA across several distressing experiences was shown in both UK and Dutch samples notably: extreme helplessness during dental treatment, lack of understanding of the dentist and extreme embarrassment during dental treatment. There were little or no effects of non-dental trauma, with the exception of sexual abuse in the UK sample.

Conclusions

Trauma from various past experiences may be implicated in an increased risk of high dental anxiety.
