Aspects Associated With Obstructive Sleep Apnea, Bruxism and Orofacial Pain

Obstructive sleep apnea (OSA) is characterized by partial or total obstruction of the upper airways. Bruxism is defined as a repetitive activity of the mandibular musculature characterized by the tightening or grinding of the teeth and/or by the retrusion or propulsion of the mandible, and according to their manifestation circadian is defined as sleep bruxism (SB) or wake bruxism (AB). This prospective clinical study will be performed with adults (20 to 60 years) and elderly (\> 60 years) (WHO-World Health Organization) who will be undergone polysomnography (PSG) at a private medical outpatients clinic from January to December 2019 to evaluate the influence of SB, AB, and OSA on signs and symptoms of TMD. The individuals will be assessed clinically and diagnosed for TMD using the "Diagnostic Criteria for Temporomandibular Disorders", for SB and OSA using PSG, and AB using the smartphone application. Specific statistical tests will be determined after preliminary analysis of the data (α= 0.05).
