This paper aimed to study on the relevance of mental health and oral health. The subjects were recruited total 3,261 elderly of over 40 years old, using the Sixth Korea National Health and Nutrition Examination Survey(KNHANES). All the collected data were analyzed by chi-square test, t-test, and logistic regression using SPSS 23.0 version. Logistic regression was used to analyze the relationship of sleeping time or stress and the number of remaining teeth, and 95% confidence intervals were computed. Sleeping time odds ratio(OR) of the number of remaining teeth was 1.52 (95% confidence interval: 1.074-2.135) and Stress odds ratio(OR) was 2.39 (95% confidence interval: 1.855-3.090), but there is no statistically significant difference after adjusted age, gender and other variables.
