Comparative StudySleep bruxism and temporomandibular disorder: Clinical and polysomnographic evaluation.
To seek better understanding of chronic musculoskeletal facial pain and its relation to sleep bruxism, by comparing patients with sleep bruxism, with and without temporomandibular disorder. ⋯ The polysomnographic characteristics of patients with sleep bruxism, with and without orofacial pain, are similar. More studies are necessary to clarify the reasons why some sleep bruxism patients develop chronic myofascial pain, and others do not.

ReviewMasticatory muscle pain and disordered jaw motor behaviour: Literature review over the past decade.
The clinically important relationship between masticatory muscle pain (MMP) and disordered jaw motor behaviour is subject of this concise, evidence-based review of the literature that was published during the past 10 years. Mainly based on studies that used some sort of experimental MMP (e.g., the intramuscular injection of noxious substances like hypertonic saline), it was concluded that MMP has pronounced effects on jaw motor functions like maximal clenching and mastication. ⋯ Further, MMP was shown to influence the cervical motor system, which may partly explain the mechanism behind the frequently observed co-occurrence of pain in the neck and the jaw. Finally, it was concluded that, even though the evidence is not yet conclusive, also remote pain (non-MMP) can modulate jaw motor behaviour, which indicates the involvement of central mechanisms in this modulation.
