Abstract

BACKGROUND:

The temporomandibular joint (TMJ) is a structure of the craniofacial complex affected by neurological diseases. Orthopedic and musculoskeletal changes can also cause temporomandibular disorders (TMD) and pain. Low-level laser (LLL) therapy has been studied in the treatment of temporomandibular jaw (TMJ) dysfunction, and controversial results were obtained.

OBJECTIVE:

The objective of this work was comparing the physiotherapeutic and drug protocol (PDP) to LLL therapy in the treatment of pain associated with TMD.

METHODS:

A sample of 60 female patients, 20-50 years of age, TMD triggering agents (stress, parafunctional habits) controlled, was randomly divided into three groups, group 1 (G1)-LLL (780 nm laser, dose of 35.0 J/cm2, for 20 sec, thrice a week, for 4 weeks); group 2 (G2)-PDP (hot packs thrice a day, morning, afternoon, and evening, for 15 min, exercise of opening and closing the mouth, twice a day, myorelaxing and anti-inflammatory drug administration); and group 3 (G3)-Placebo (450 nm halogen lamp, Max LD Gnatus, light curing unit).

RESULTS:

Patients were evaluated every return appointment for the presence (P) or absence (A) of pain for 4 weeks and results were statistically analyzed. First week: 60% of G1, 100% G2, and 70% of G3-related pain. Second week: 55% of G1, 15% of G2, and 100% of G3-related pain. Third week: 10% of G1, 15% of G2, and 85% of G3-related pain. Last week: 0% of G1, 0% of G2, and 100% of G3-related pain.

CONCLUSIONS:

Based on obtained data, we concluded that, compared to PDP, LLL treatment is effective to control pain associated with TMD.
