Objectives: The aim of the study was to investigate the association of self-perceived oral health and depression in the Korean elderly. Methods: The subjects were 1,329 elderly in Korea from the sixth Korea National Health and Nutrition Examination Survey (the 6th KNHANES). The dependent variable was depression that continued more than two weeks. Model I for the impacts of depression on self-reported oral health, Model II for the impacts of depression on chewing problem, Model III for the impacts of depression on speaking problem was evaluated. PASW Statistics 18.0 version was used for frequency analysis, chi-square test and logistic regression analysis. Results: Female elderly were much more prone to depression than male. Female had lower monthly compensation, less medicaid, chewing problem, speaking problem, and less education. For these reasons, they tended to have more depression than male (p<0.001). Self-perceived oral health impacts on depression included poor self-reported oral health(p<0.01), poor chewing problem(p<0.01) and poor speaking problem(p<0.05). On the other hand, male did not show a statistically significant association. Conclusions: The study showed the self-perceived oral health related quality of life had a significant influence on depression in the elderly. The continuing lifelong oral health care can prevent depression in the later life because oral health care improvement can enhance the self-perceived oral health status.
