Abstract

Background: Dental phobia is associated with poorer dental attendance so epidemiological surveys requiring participants to undertake a dental examination may result in an under-representation of participants with high dental fear. Method: We compared the dental fear distribution of participants and non-participants in an oral examination component of a national epidemiological survey of oral health. Of 12,606 in-scope dentate people aged 15+ who completed a structured computer-assisted telephone interview (CATI) survey, 5,505 (43.7%) participated in the oral examination. Dental fear was assessed with a single-item measure in the CATI. Results: There was a significant difference between the percentages of participants and non-participants who rated themselves as "extremely" afraid, although the absolute difference (1.9%) was small. The association between extreme dental fear and participation was significant (OR = 0.66, 95% CI = 0.5-0.77) in multivariate analyses after controlling for possible confounders. Females with extreme dental fear were also significantly less likely to undertake an oral examination. Conclusion: Even though people with dental fear and phobia may delay or avoid dental visits, they do not appear to be appreciably under-represented in oral epidemiological surveys.
