OBJECTIVE: This study aimed to determine the prevalence of sleep disturbance among patients with temporomandibular disorders (TMDs) and to identify clinical and psychological predictors associated with its presence. METHODS: This retrospective cross-sectional study analyzed clinical records of 299 adult patients diagnosed with TMDs at a tertiary orofacial pain clinic between 2016 and 2021. Sleep disturbance was defined as the presence of pain-related sleep interference based on the Thai Brief Pain Inventory and clinical documentation. Variables included TMDs subtypes, pain intensity, number of facial pain sites, presence of widespread pain, fibromyalgia risk, bruxism, and psychological distress. Multivariable logistic regression then was performed to identify independent predictors. RESULTS: = .023). CONCLUSION: Sleep disturbance was common among patients with TMDs. Psychological distress was strongly associated with sleep disturbance. These findings suggest that routine assessment of sleep and psychological factors may be useful in the management of TMDs.
