Aspects Associated With Obstructive Sleep Apnea, Bruxism and Orofacial Pain

Observational Study on Aspects Associated With Obstructive Sleep Apnea, Bruxism and Orofacial Pain

This study evaluated the influence of the sleep bruxism (SB), awake bruxism (AB) and obstructive sleep apnea syndrome (OSAS) on the signs and symptoms of temporomandibular disorders (TMD).

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).

Inclusion Criteria:

• Adults (aged 20 to 60 years) and elderly (aged > 60 years) (WHO-World Health Organization, 2015) who will be undergone PSG at the Pelotas Sleep Institute (ISP);
• Adequate cognitive capacity to understand and answer the questionnaire.

Exclusion Criteria:

• Those which the participants were unable to answer the questionnaires and who presented a history of epilepsy that could interfere in the results of PSG.
