Temporomandibular Disorder | Low-level Laser Therapy on Temporomandibular Disorder

Temporomandibular Disorder research study

What is the primary objective of this study?

The purpose of this study is to assess the effect of low-level laser on pain, occlusal contacts, mandibular movements and electromyography activity in the masseter and temporal muscles in adolescents with TMD.

Who is eligible to participate?

Inclusion Criteria: - Individuals aged 15 to 18 years with diagnosis of TMD and a signed statement of informed consent will be included in the study. Exclusion Criteria: - Individuals with dentofacial anomalies, incomplete permanent dentition to the 2nd molar, currently undergoing orthodontic or orthopedic treatment of the jaws, currently undergoing psychological treatment or physical therapy and making use of a muscle relaxant, anti-inflammatory agent or bite plate will be excluded from the study.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Temporomandibular Disorder

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Procedure:low-level laser treatmentA gallium-aluminum-arsenide laser will be employed for the LLLT and placebo treatment. The device will be calibrated with a wavelength of 780 nm, energy density of 25 J/cm2, power of 50 mW and power density of 1.25 W/cm2. Exposure time will be 20 seconds per point, resulting in a total energy of 1 J per point. The spot application method will be used in contact with the skin and with a conventional tip, covering an area of 0.04 cm2.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Muscles of masticationThis group with TMD will receive low-level laser treatment at masseter and temporal muscles - three points on the masseter (upper, middle and lower) and one point on the anterior temporal

TMJ and musclesThis group with TMD will receive a mixed application of low-level laser treatment- TMJ and muscles of mastication.

PlaceboThis group with TMD will receive a low-level laser placebo treatment at TMJ and muscles of mastication. The same equipment will be used with a pen that emits a red guide light and a warning sound, but without the emission of laser

Tempormandibular JointThis group with TMD will receive low-level laser treatment in TMJ region - five points around the TMJ.

Withou TMDThis will be a follow up group, with volunteers without TMD.
