Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To verify if the use of low level laser therapy diminishes the pain in the region of temporomandibular joint and facial and cervical immediately after the application (discomfort in the trigger points, in the masticatory muscles in static or dynamic examination in the accomplishment of the protrusion movements and right and left laterality). Measured by the visual analogue scale during palpation and mandibular movements. | — |
Secondary
| Measure | Time frame |
|---|---|
| Check if that symptoms related to TMD and facial and cervical pain improve immediately after application of LBP (mouth opening range, mouth opening trajectory range). Measured by using a caliper and ruler.;To verify the duration of the decrease of the pain in the region of temporomandibular joint, facial and cervical caused by the laser therapy, if observed. The data will be obtained by reporting the participant daily based on the visual and analog scale and marked in a standardized form provided by the researcher after the first and second sessions.;Check if there is "clicking" and / or "crackling" the decrease occurs after laser therapy. It will be measured by the researcher during the clinical examination.;Verify if laser therapy improves quality of life. It will be measured by decreasing the score obtained at the beginning and at the end of the laser therapy. This information will be obtained with the application of the OHIP-14 (Oral Health Impact Profile) questionnaire that will be applied at the beginning and after the third laser therapy session.;To verify if the laser therapy improves the perception of the quality of sleep. It will be measured by decreasing the score obtained at the beginning and at the end of the laser therapy. This information will be obtained with the application of the Epworth scale, which will be applied at the beginning and after the third laser therapy session. | — |
