OBJECTIVES: This study discussed dental care utilization efficiency and equity from the perspective of private health insurance policy using the 2011 Korea Health Panel dataset.
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 health insurance on utilization and amount of dental care.
Average monthly payment of private health insurance is 76,727 KRW. Analysis of average monthly fees and income distribution by quartile showed that higher income groups pay proportionally more for private health insurance. The highest income group was 3.82 times more likely to have private health insurance than the lowest income group. Those with private health insurance coverage had a higher probability of using dental care but were not more likely to use a greater number of dental services.
Based on these empirical findings, a guarantee of health care system and policy equity and efficiency should be established for changes in private health insurance.
