Assessment of demand for and utilization of dental services by insurance coverage in a developing oral health care system

Objectives: This study aimed to evaluate the relationship between demand for and utilization of dental services by insurance coverage among adults in Iran. Methods: A cross-sectional survey based on telephone interviews was done. A total of 6,029 adults participated in this study conducted in Iran. The interviews were carried out using a structured questionnaire and covered dental visits, demographics and socio-economic background. Results: Of 6,029 participants, 86% reported having health insurance; 58% had public, and 28% had both public and commercial insurance. Those with both public and commercial insurance coverage had higher odds for dental visits within the past 12 months [odds ratio (OR)=1.5], and for dental check-ups (OR=1.5). Receipt of restorative and expensive services (OR=1.4) was more likely by those with both public and commercial insurance. Tooth extraction was more likely in subjects with no insurance coverage (OR=1.6). Conclusion: This study revealed a positive relationship between insurance coverage and demand for and utilization of dental services in a country with a developing health care system.
