The study was conducted on TMD patients who were willing to participate in the study between January and December 2020.~The case-control study included patients diagnosed with myofascial TMD by dental practitioners at regional hospitals referred for physiotherapy. Total of 200 myofascial TMD patients, comprising 91 identified as SB and 109 as non-SB were included in the study.~The Jaw Function Limitations Scale (JFLS), Neck Disability Index (NDI), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), and Headache Impact Test-6 (HIT-6) scales and indexes were used for both groups.~The effect of Sleep Bruxism (SB) on jaw function, neck problems, sleep quality, fatigue, and tension headache were evaluated.~The interactions of these factors and the importance of taking SB into consideration when evaluating and treating patients with TMD were examined.
The aim of the study was to assess and compare the relationship between jaw function, neck disability, sleep quality, fatigue, and headache in patients with myofascial Temporomandibular Disorder (TMD) with Sleep Bruxism (SB) and without (non-SB).
