Photobiomodulation With Red and Infrared LED Device for Temporomandibular Dysfunction

November 6, 2018 updated by: Sandra Kalil Bussadori, University of Nove de Julho

Effects of Photobiomodulation With Simultaneous Use in a Same LED Device (Red and Infrared) on Clinical Aspects in Individuals With Temporomandibular Dysfunction: Clinical, Randomized, Controlled and Blind Trial.

Temporomandibular Dysfunction - TMD is considered the main cause of orofacial pain of non-dental origin, and a public health problem. Due to their complexity there are already treatments using various forms of therapy. Photobiomodulation using different light sources, in a single or combined form, makes it possible to use it as another therapeutic resource to be explored. The objective of this study will be to evaluate the effects of photobiomodulation with simultaneous use of light emitting diodes (LEDs), red and infrared, on clinical aspects in individuals with TMD. A randomized, controlled and blind clinical trial is proposed, which will involve 33 individuals (n = 11 per group) of both genders, aged 18-45 years in three groups: Group 1 - LED; Group 2 - placebo and Group 3 - control, submitted to 6 nonconsecutive sessions of photobiomodulation totaling 2 weeks of treatment. The Research Diagnostic Criteria for Temporomandibular Disorders - RDC/TMD will be used to determine the TMD and evaluate the participants. Pain will be assessed using the visual analog scale (VAS), mandibular range of motion will be determined with the aid of a digital caliper, and the electrical activity of the masticatory muscles will be verified by electromyography. A mixed plate of 18 red LEDs - 660 nm and 18 infrared LEDs - 850 nm with power of 3.5 mW per LED, 4.45 mW/cm2, radiant exposure of 5,35 J/cm2, irradiated area of 14.13 cm2, and energy of 75.6 J, in the temporomandibular joint (TMJ) region and in the masseter and temporal muscles, bilateral in 6 sessions. Participants from all groups will be reassessed after the first therapeutic intervention, and again at the end, following the same evaluation procedures used initially.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Active Comparator: LED group
LED photobiomodulation will be applied at 36 points, bilaterally, in the temporomandibular joint regions, around these joints, and in the regions of the masseter muscles and anterior part of the temporal muscles, three times a week, totaling 6 treatment sessions, in 2 weeks. The LED apparatus is composed of a flexible rectangular plate (10cm/12cm), which adapts to the format of the area to be treated containing 18 red LEDs - 660 nm and 18 infrared LEDs - 850 nm, with a power of 3.5 mW by LED, 4.45 mW/cm2, radiant exposure of 5.35 J/cm2, radiated area of 14.13 cm2, and energy of 75.6 J.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Visual Analog Scale (VAS)
Time Frame: Fourteen days.
VAS is an instrument that allows easy measurement of pain intensity, and consists of a straight line 10 cm long, whose extremities have a verbal description (no pain and worse pain already felt, respectively), in which the participants will be asked to perform a perpendicular trait between the two extremes that represents the level of pain he/she presents at that moment. This will be evaluated at baseline, immediately after treatment and at the end of the treatment.
Fourteen days.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Range of motion
Time Frame: Fourteen days.
A digital Starrett® caliper will be used to assess mandibular range of motion (in millimeters), that is, measure mouth opening, lateral deviations (right and left) and protrusion. This procedure composes the clinical evaluation of RDC/TMD. This will be evaluated at baseline, immediately after treatment and at the end of the treatment.
Fourteen days.
Electromyography
Time Frame: Fourteen days.
The electrical signals of the right and left masseters and anterior temporal muscles will be captured. We will use an EMG System do Brasil® signal conditioning module, with eight channels (module 830 C), using frequency bandpass filter between 20-1000 Hz, common mode rejection index> 120 db. All data will be collected and processed using a 16-bit analog / digital converter (EMG System do Brasil®). This will be evaluated at baseline, immediately after treatment and at the end of the treatment.
Fourteen days.
