This study was conducted to investigate the status of oral health behavior according to economic inequality in Korea. Raw data for the 3rd year (2015) of the 6th national health and nutrition survey were analyzed. Among surveyed individuals, adults over the age of 19 were designated as research subjects. The results indicated that a smaller 'house income' was associated with a higher supply and demand experience for basic living and a higher DMFT. Additionally, a higher DMFT was associated with a lower 'house income', lower 'education level', and the 'experience of basic living security received'. Oral health behavior inequality was caused by economic inequality. Overall, these results indicate that it is necessary for the oral health service of vulnerable groups to strengthen preventive activities through comprehensive arbitration policies regarding the social decision factors of public health projects.
