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.
| Study group | Role | What they receive |
|---|---|---|
| with sleep bruxism, apnea and DTM | Patients who will undergo analysis of:
Evaluation of TMD and pain sensitivity Evaluation of SB Evaluation of AB Receives: Diagnostic Test: Evaluation of TMD and pain sensitivity; Diagnostic Test: Evaluation of SB; Diagnostic Test: Evaluation of AB |
What is being measured
The primary outcome is the main question the study is designed to answer.
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)
TMD assessment
All patients who had undergone polisomnography will answer the DC / TMD questionaire and clinical exams.
Measured: 6 months after study start
Diagnosis of awake bruxism
All patients will use a Smartphone application after undergone polisomnography
Measured: 8 months after study start
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

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).
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Bruxism and Temporomandibular Joint Disorders, run by Federal University of Pelotas at 1 site in Brazil.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Polisomnography analysis (time frame: 4 months after study start). It is what the study was designed to measure, not a finding.
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Mar 2022.
