Objectives: This study discussed dental care utilization efficiency and equity from the perspective ofprivate health insurance policy using the 2011 Korea Health Panel dataset. Methods: A total of 10,577 subjects, aged 20 years or older, were selected from a larger sample(N=18,256). The study conducted a two-part model analysis to determine the impact of private healthinsurance on utilization and amount of dental care. Results: Average monthly payment of private health insurance is 76,727 KRW. Analysis of averagemonthly fees and income distribution by quartile showed that higher income groups pay proportionallymore for private health insurance. The highest income group was 3.82 times more likely to have privatehealth insurance than the lowest income group. Those with private health insurance coverage had ahigher probability of using dental care but were not more likely to use a greater number of dental services. Conclusions: Based on these empirical findings, a guarantee of health care system and policy equityand efficiency should be established for changes in private health insurance.
