OBJECTIVES: In order to aid the development of practical oral health improvement programs for adults, this study examined whether a correlation exists between oral health indices assessed by experts and self-perceived oral health status.
Raw data from the second year (2013–2015) of the sixth Korea National Health and Nutrition Examination Survey were analyzed. Among those surveyed, adults over the age of 19 were designated as research subjects.
The DT indices, prosthetics indices, and Community Periodontal indices were higher when the subjective oral health status was “Bad.”
The results of this study demonstrated the consistency between subjective and objective oral health status. Thus, self-perceived oral health status is a reliable index to evaluate adult oral health projects for improving the quality of life of adults, improving their oral health, and evaluating future oral health services.
