Temporomandibular Disorder
Conditions
Brief summary
This study is blind, randomized controlled and have been carried out on children between 6 and 9 years of age, at the Catholic University of Uruguay, Faculty of Health Sciences, Postgraduate School, and surrounding schools. Patients who present temporomandibular disorders, based on the diagnostic criteria will be the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) were included. The laser used was infrared, power 100 mW ±20%, wavelength 660nm ±10 nm, energy parameter 60J, continuous application. The technique is not invasive, the irradiation point is by continuous and direct transcutaneous application to the radial artery by means of a bracelet that inserts the laser beam. One session has been performed. There was a laser group, a placebo group. Participants in all groups were re-evaluated after the procedure, following the same evaluation procedures used initially, evaluating the effects of ILIB on pain and range of motion.
Interventions
RADIATIONVascular photobiomodulation (VPBM)
The participants received a 20-minute single session of VPBM. This noninvasive method involves the use of low-power laser coupled to a bracelet designed to transport the light beam transcutaneously over the radial artery. The laser device (DMC Therapy Ec) delivered irradiation with a power of 100 ± 20 mW, wavelength of 660 ± 10 nm (red light) and energy of 120 J applied continuously, with irradiance of 35 W/cm².
RADIATIONSham group (simulated vascular photobiomodulation)
Simulated radiation. The participants received a single session.

SINGLE (Subject)
Masking description
Participants in the placeb group will be treated in the same way as the active laser group. The person in charge of the application will simulate the irradiation with the equipment kept off, so that the participant does not identify the group to which he/she belongs to, and the device activation sound (beep) will be turned on at the time of application.

Age
6 Years to 9 Years
Healthy volunteers
Yes
Inclusion criteria
* Healthy participants (ASA I) age six to nine years with diagnosis of TMD in the mixed dentition phase and with jaw deviation and/or deflection. Deviation is defined as the jaw following a deviated path to one side during opening. Deflection is defined as the jaw following a deviated path without returning to the midline when the mouth is fully opened.
Exclusion criteria
* Craniofacial anomalies or genetic syndromes due to the greater probability of the development of TMD associated with the malformation, which could be a confounding variable, malocclusion, use of a dental prosthesis, currently undergoing orthodontic treatment, need for orthognathic surgery or physical therapy due to the potential impact on the results of both the diagnosis and treatment, currently undergoing oncological treatment due to the need to avoid conditions that may exert an influence on the response to the proposed treatment and photosensitivity due to the incompatibility with part of the proposed treatment. Individuals on medications could be included and the medications needed to be recorded in the results.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in mouth opening range of motion (following clinical protocol of DC/TMD) | Baseline and immediately after the procedure. | Vertical movement of the jaw was measured using calibrated digital calipers. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in Pain Evaluation | Baseline and immediately after the procedure. | Pain was assessed using the VAS, which is an instrument for the subjective assessment of pain. The subject makes a mark along a horizontal line with 0 (absence of pain) printed at one end and 10 (extreme pain) printed at the other end. The patient's mark on the line is recorded in the clinical history for reproduction among observers. |
