Design outcomes

Primary

MeasureTime frame
To assess whether the implementation of photobiomodulation protocol can be effective in reducing pain intensity and improving mobility in patients with temporomandibular disorders. Verification by the methods Numerical Pain Scale (NPS), which is a numerical scale in which a line with numbers from 0 to 10 arranged horizontally in increasing sequence is drawn on it, and the patient is then asked to evaluate and mark on the line the number of pain at that moment; Diagnostic Criteria for Temporomandibular Disorders (DC/DTM) questionnaire, in which axis I will be used, which classifies patients into three groups, muscular Temporomandibular Disorders, articular disc displacements, and the following questionnaires and tests will be used: Temporomandibular Disorders Pain Screener, Symptom Questionnaire, Demographics, Pain-related Interview and Examination Commands, Clinical Examination Form (FDI), Decision Tree, Diagnostic Criteria Table, to assess reports of pain and symptoms; axis II of the same will also be used to assess pain, functional limitation, with the following questionnaires and tests Pain Drawing, Graded Chronic Pain Scale Version 2, Jaw Functional Limitation Scale - 8 (JFLS-8); mandibular mobility index that analyzes the mobility of the jaw in the opening, laterality and protrusion movements, for each item three values ??are given (0, 1 and 5) to be scored according to the clinical evaluation, finally a sum of the values ??is made and the patients are classified as without Temporomandibular Disorders symptoms (0 points), mild symptoms (1 to 4 points), moderate (5 to 9 points) and severe (10 to 25 points)

Secondary

MeasureTime frame
To assess whether the implementation of manual therapy techniques can be effective in improving the quality of life of patients with temporomandibular disorders. Verified by Disgnostic Criteria for Temporomandibular Disorders (DC/DTM) methods, in which axis II will be used to assess parafunctional behaviors with the following Oral Behaviors Checklist (OBC) test; Oral Health Impact Profile - 14 (OHIP-14), which will be used to assess the impact of oral conditions on the quality of life of patients
