Abstract

Chronic orofacial pain is a generic term used to describe painful regional syndromes with unremitting pattern. Individuals with this condition may present sleep disorders compromising sleep quality as well as quality of life. The objective of this study was to review the literature about sleep quality in patients with chronic orofacial pain. A systematic literature search was conducted on PubMed. The search was limited to clinical and laboratory trials that were published in English between 2005 and 2015. The search strategy used the following terms: (Temporomandibular Joint Disorders) or (temporomandibular joint dysfunction syndrome) or (orofacial pain) or (chronic pain) and (sleep disorders). It was found 426 articles, but only 17 fit the inclusion criteria. Studies have shown an association between chronic orofacial pain and poor sleep quality since individuals with this condition are prone to having sleep disorders compromising its quality, the opposite is true. It was observed that sleep can be related to the sensitization of the central nervous system and to the exacerbation of pain associated with chronic pain and pain sensitivity degree. Notwithstanding, the causeeffect relationship is still unclear among researchers, so it is necessary to carry out more studies in the area for the complete elucidation of the subject.
