Overview

Photobiomodulation (PBM), is FDA-approved for temporary relief of muscle and joint pain, but there is no indication for TMD. Our goal in this study is to conduct a clinical trial of multimodal PBM for TMD pain. This study will be a double-blind, sham-controlled, randomized trial testing the efficacy of PBM for pain related to TMD.
