OR Odds ratio, CI Confidential interval, ESS Epworth sleepiness scale. Multivariate logistic regression analysis was performed to comprehensively examine the factors affecting poor sleep in chronic TMD patients (R = 0.833, R square = 0.787). For obtaining significant results, two-tailed level of statistical significance of a p-value was set at less than 0.05
