The Prevalence of Dental Anxiety in Dental Practice Settings.

Purpose: The purpose of this study was to assess the prevalence of dental anxiety and missed dental appointments due to dental anxiety among patients within three types of private dental offices. Methods: This descriptive, cross-sectional study utilized the Modified Dental Anxiety Scale (MDAS). The MDAS consists of five questions to assess dental anxiety. Demographics and an open-ended question about missed dental appointments due to dental anxiety were included. Linear and logistic regression models were used to analyze anxiety scores as related to gender and age. Participants' responses to the open-ended question were compiled according to themes. Results: Three hundred and eight (n=308) dental patients participated in the study. Using the MDAS cut-off scores of 15 and 19, the prevalence estimates of moderate to high and high dental anxiety within the total study population was 19% and 6.82% respectively. Females had an MDAS score 2.12 times higher than males (p<0.05). For every one unit increase in age, the MDAS score was 0.08 units lower (p<0.05). Out of the 308 participants, 26 (8.4%) responded to missing a dental appointment due to dental anxiety. Five common themes were coded as the source of dental anxiety: fear of dental experience, previous negative dental experience, cost of treatment, gag reflex, and fear of bad news. Conclusions: Moderate to high dental anxiety was present in 19% of the population sampled. Awareness of patients' dental anxiety level and the utilization of anxiety reducing measures during treatment may encourage routine care.
