Arms Assigned Interventions
Red laser
On the pain points of muscle, laser was applied (8J/cm ²) with an interval of 48 hours between applications. In the joints with sensitivity, a dose of 4J/cm2 laser was applied with an interval of 48 hours between applications.
Radiation: Red laser
On the pain points of muscle, laser was applied (8J/cm ²) with an interval of 48 hours between applications. In the joints with sensitivity, a dose of 4J/cm2 laser was applied with an interval of 48 hours between applications.
Infrared laser
On the pain points of muscle, laser was applied (8J/cm ²) with an interval of 48 hours between applications. In the joints with sensitivity, a dose of 4J/cm2 laser was applied with an interval of 48 hours between applications.
Radiation: Infrared laser
On the pain points of muscle, laser was applied (8J/cm ²) with an interval of 48 hours between applications. In the joints with sensitivity, a dose of 4J/cm2 laser was applied with an interval of 48 hours between applications.

Detailed Description:
The aim of the present study was to evaluate and compare the efficacy of red (600nm) and infrared (800nm) laser therapy in relieving pain and improving the quality of life of TMD patients.
