Efficacy of Red and Infrared Lasers in Treatment of Temporomandibular Disorders

Study Overview
=================
Brief Summary
-----------------
The study hypothesis was that the red (600nm) and infrared (800nm) laser therapy have the same efficacy in relieving pain and improving the quality of life of TMD patients

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.
