The Epworth Sleepiness Scale (ESS) was used to classify patients into EDS group (score\u2009\u2265\u200910) and non\u2010EDS group (score\u2009&lt;\u200910). The Jaw Functional Limitation Scale 8\u2010item (JFLS\u20108) was used to assess the severity of jaw dysfunction. Pain intensity was evaluated using the Visual Analogue Scale (VAS). Anxiety and depression were evaluated using the Generalised Anxiety Disorder 7\u2010item (GAD\u20107) and the Patient Health Questionnaire 9\u2010item (PHQ\u20109). All included patients were diagnosed with pain\u2010related TMD (PT), intra\u2010articular TMD (IT) or combined TMD (CT).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared with non\u2010EDS patients, EDS patients exhibited more severe jaw dysfunction, greater pain intensity and higher PHQ\u20109 scores (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Multivariate analyses showed that EDS (<jats:italic>B<\/jats:italic>\u2009=\u20093.69), female gender (<jats:italic>B<\/jats:italic>\u2009=\u20093.69), and elevated GAD\u20107 score (<jats:italic>B<\/jats:italic>\u2009=\u20090.73) were significantly associated with an increased score on the JFLS\u20108 (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Moreover, bivariate logistic regression analysis indicated a significant relationship between EDS and PT (OR\u2009=\u20092.70, <jats:italic>p<\/jats:italic>\u2009=\u2009.007).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The presence of EDS was more closely related to PT, but the causal relationship between them needs to be further confirmed. More concern and intervention to alleviate poor sleep quality might be highlighted during the treatment of TMD, especially PT
