The purpose of this study was to investigate the relationship between objective oral health status and
subjective oral health awareness of Korean adults. Results showed that as Korean adults perceived that their
oral health was good, the lower the prevalence of periodontal diseases and dental caries. Therefore, we
think that a dental health education program needs to be developed for the prevention of periodontal
disease and dental management based on the objective oral health status index, including periodic oral
checkup.
