Brief Summary

Temporomandibular disorder (TMD) is described as a subgroup of orofacial pain with a set of signs and symptoms that involve the temporomandibular joint, masticatory muscles, ears and neck. TMD can occur unilaterally or bilaterally and approximately 70% of the population is affected with at least one sign. The disorder progresses with orofacial pain, muscle pain involving the masticatory and cervical muscles, joint noises (clicks and pops), joint block, mandibular dysfunction and headache. The etiology can be abnormal occlusion and/or posture, trauma involving local tissues, repetitive microtrauma, parafunctional habits and an increase in emotional stress. Studies have demonstrated that phototherapy is an efficient option for the treatment of TMD, leading to improvements in pain and orofacial function. The aim of the proposed study is to analyze the effects of low-level laser therapy and light-emitting diode (LED) therapy on pain and function in patients with TMD. Methods: A randomized, controlled, double-blind, clinical trial is proposed, which will involve 80 individuals between 40 and 70 years of age allocated to either a laser group or LED group submitted to twelve sessions of phototherapy. The Research Diagnostic Criteria for TMDs will be used to evaluate all participants. Pain will be measured using the visual analog scale. Orofacial function will be measured based on maximum vertical mandibular movement and muscle tension (determined through palpation of the masseter, temporal, frontal, sternocleidomastoid, suboccipital and trapezius muscles). Electromyographic analysis of the masseter and anterior temporal muscles will also be performed.

Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale

    This scale will be used for the assessment of pain and consists of a 10-cm line with 0 (absence of pain) printed at one end and 10 (debilitating pain) printed at the other end. The participants will be asked to mark a place on the line that represents their current pain intensity. The researcher will subsequently use a ruler to register the distance from zero to obtain a numeric representation of the pain level. These procedures will be performed before and immediately after treatment.

    Through study completion, an average of 1 year.

Other Outcomes (4)

  • Visual Analog Scale

    Through study completion, an average of 1 year.

  • Maximum vertical mandibular movement

    Through study completion, an average of 1 year.

  • Muscle tension

    Through study completion, an average of 1 year.

Study Arms (2)

LED group

EXPERIMENTAL

The groups will be submitted to 12 sessions of phototherapy held twice a week for six weeks, during which only the researcher in charge of programming the phototherapy device will be aware of which treatment is being employed. However, the programmer will not participate in the execution of the treatments, evaluations or data analysis.

Radiation: LED therapy
