Objectives: This study used raw data from the 7th National Health and Nutrition Survey to identify subjective health status and DMFT perceived by the elderly and provides basic data for the development of continuous oral health care programs. Methods: For statistical analysis, frequency analysis, t-test, ANOVA and multiple regression analysis were performed using the IBM SPSS Statistics Base 22.0 program. Results: The significance was verified, and the explanatory power was 21.0%. As a result of analyzing factors influencing DMFT, age and home ownership were verified, and explanatory power was 15.1%. Conclusions: As age increased, it was possible to confirm the oral condition, in which the dental condition was deteriorating, and the possession of housing related to socio-economic power were also found to be highly related to dental condition. Therefore, considering the diversification of socio-economic characteristics, attention is needed for the elderly in the socially vulnerable class.
