Objectives: The objective of this epidemiological survey was to analyse the association between dental anxiety and health-related quality of life (HRQL) among adults.
Methods: Individuals were randomly selected (n = 3500), and they were interviewed by telephone and asked to complete a questionnaire concerning dental anxiety, HRQL [Oral Health Impact Profile-5 (OHIP-5) and EuroQol-5D (EQ-5D)] and several socioeconomic variables.
Results: Dental anxiety was revealed as a significant factor relative to the OHIP-5 and EQ-5D. Dental anxiety had a stronger association with the OHIP-5 [odds ratio (OR): 3.50] than with the EQ-5D (OR: 1.75). In addition, socioeconomic status demonstrated a gradient, with higher ORs the lower the income and the likelihood of reporting poor HRQL.
Conclusion: High dental anxiety was associated with lower HRQL.
