OBJECTIVES: The purpose
of this study was to investigate effective predictive factors of the persistence of unmet dental care needs.
Data were obtained from the Korea Health Panel studies of 2011 and 2015, and 4,406 subjects, aged 18 years or older, were included in this study. Of these subjects, those who persistently experienced unmet dental care needs over the three-year period were identified. Panel logistic regression analyses were conducted to identify socio-demographic and health-related factors associated with the persistence of unmet dental care needs in two groups, those aged between 18–64 years and over 65 years.
Approximately 12% of subjects showed a persistence in unmet dental care needs. Marital status, education level, household income, type of health insurance, and self-rated health status all significantly correlated with the persistence of unmet dental care needs in both age groups.
Efforts should be made to identify factors related to the persistence of unmet dental care needs in order to improve patient accessibility to dental care services.
