RESUMO
To assess the frequency and causes of dental anxiety and their relation to irregular dental visits among adult dental patients. The Dental Anxiety Question [DAQ] included within a self-administered questionnaire was distributed to 1025 patients attending the Interns' Dental Clinics in the Department of Preventive Dental Sciences, College of Dentistry, University of Dammam, Dammam, Kingdom of Saudi Arabia from March 2012 to February 2013. A cross-sectional study design was used. The questionnaire consisted of 22 closed-ended questions divided into 4 sections; 1] demographics, 2] regularity of dental visits, and related causes, 3] DAQ, cancellation of dental appointments, history of previous trauma, dental anxiety provoking factors within dental environment and procedures, and 4] patients' status in dental clinics, preferences of dentists, and perceptions regarding dental anxiety. The prevalence of dental anxiety among the study sample was 27%. Anesthetic injection was the main factor of dental fear [88.2%], while dental surgical procedures [35.7%] and extractions [23%] were the most terrifying dental procedures. Lack of time [79.5%], cost [71.5%], far-situated dental services [62.2%], and fear [57.1%] were causes listed for irregular dental visits; while 31.3% had no specific reason. Irregular dental visits were not related to dental anxiety. Dental anxiety continues to be an obstacle despite the vast improvement in dentistry; and this raises an alert regarding personal and communication factors in the patient-dentist relationship. Factors such as equal distribution of dental services, time, and cost should also be addressed
