Association of stress, anxiety, and depression levels with sleep quality in patients with temporomandibular disorders.

OBJECTIVE: To examine the psychological symptoms of TMD and their effects on sleep quality in patients with temporomandibular disorders. METHODS: The study was carried out with 425 consecutive TMD patients who sought care at the oral and maxillofacial surgery clinic of a faculty of dentistry. Perceived Stress Scale-14, Beck Anxiety Scale, and Beck Depression Scale were used to evaluate the psychological state. Sleep quality was evaluated with the Pittsburgh Sleep Quality Index. RESULTS: The mean sleep score of all participants was 6.52. As the level of anxiety and depression increased, the scores of both total sleep quality and sleep quality components increased significantly p < 0.01. On the other hand, those with poor sleep quality had significantly higher stress, anxiety, and depression levels than those with good sleep quality p < 0.01. CONCLUSION: Negative emotional situations such as stress, anxiety, and depression seriously impair sleep quality in TMD patients.
