About this study

Official title: 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).

Read the detailed description

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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Evaluation of TMD and pain sensitivityDiagnostic test

    Extra and intraoral clinical examination will be performed and the Diagnostic Criteria for Temporomandibular Disorders (DC / TMD) questionnaire will be applied. Measurements shall be bilateral in the masseter, anterior temporal and tenar muscles and the arithmetic mean between three measurements will be considered the value for each side for pain sensitivity analysis with an dynamometer.

  • Evaluation of SBDiagnostic test

    The presence or absence of SB will be diagnosed by Polysomnography

  • Evaluation of ABDiagnostic test

    A smartphone will be used, which was developed for a momentary evaluation that allows a report of the exact moment of AB and its possible associated symptoms.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Polisomnography analysis

    Patients included in the study will receive polisomnography exams for diagnosis of SB and OSAS. The data will be obtained from polisomnography records

    Measured: 4 months after study start

Secondary outcomes (3)
  1. TMD assessment

    All patients who had undergone polisomnography will answer the DC / TMD questionaire and clinical exams.

    Measured: 6 months after study start

  2. Diagnosis of awake bruxism

    All patients will use a Smartphone application after undergone polisomnography

    Measured: 8 months after study start

  3. TMD pain

    All patients who had undergone polisomnography will answer the DC / TMD questionaire and clinical exams with algometer.

    Measured: 10 months after study start

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03766464, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
