Abstract
Objectives: The purpose of this study was to examine oral health perception of Korean adult population. And the association of self-rated oral health with oral epidemiological indicators under the control of demographic, socioeconomic factors and oral health related behaviors was tried to clarify. Methods: The oral examination and survey data of 4,428 subjects over 18 years were analyzed. Baseline-category logits model was used to multivariate analysis for perceived oral health of young middle and old age groups. Results: 43.67% of Korean adults rated their oral health as poor, 28.77% as fair, and 27.55% as good. In young age group of 18-34 years old, living in metropolitan area, low income, lower DMFS index, no fixed bridge, no bleeding gum or calculus, no worry about their oral health, and use of oral hygiene products were positively associated with self-rated oral health. In middle age group of 35-64 years old, older age, middle income than low, professional job, lower DMFS index, more remaining teeth, no bridge, no periodontal pocket, no worry about their oral health, and brushing more than 4 times were positively associated with self-rated oral health. In old age group of over 65 years old, older age, living in metropolitan area, no job, more remaining teeth, no denture, no periodontal pocket, and no worry about their oral health were positively associated with self-rated oral health.Conclusions: Self-rated oral health is a simple measure and reflects not only objective oral status but also socioeconomic status and psychological effect as worry about oral health. So, we should actively use the perceived oral health to promote nation's actual oral well-being.
