Dental anxiety. Dental fear. Quality of life. Oral health.


Aim: The aim of the study was to investigate levels of Dental Fear (DF) and Dental Anxiety (DA) among individuals awaiting appointments at the clinics of two courses in dentistry and determine the impact on oral health status and quality of life. Methods: An observational study was conducted with a sample of adult dental patients. Levels of DF and DA and the perception of quality of life were determined using questionnaires and periodontal data. Results: Among the 287 subjects, 71.4% were female, 7.3% were classified as very anxious and 16% were classified as anxious. Gender was significantly associated with DA (p = 0.001); 20% of the female volunteers and 6.1% of the males were classified as anxious. The frequency of moderate and extreme fear was 42.9% and was not significantly correlated with gender (p = 0.071). The prevalence of a negative impact from oral health status on quality of life (measured using the OHIP-14 scale) was 38.3% and income was significantly associated with this outcome (p = 0.000). Conclusion: Levels of DA and DF were substantial among the individuals analyzed. Women with a lower education were susceptible to anxiety. DA and DF were  associated with periodontal status or impact on quality of life.
