What this trial studies

This clinical trial investigates the use of photobiomodulation (PBM) therapy to alleviate pain associated with temporomandibular disorders (TMD). It employs a double-blind, sham-controlled, randomized design to assess the efficacy of the THOR® laser system in providing pain relief. Participants will be monitored for their pain levels and overall response to the treatment over the course of the study. The aim is to establish a new therapeutic approach for managing TMD pain, which currently lacks FDA-approved treatments.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have been experiencing facial pain related to TMD for at least three months.

Not a fit: Patients with active rheumatologic diseases or other significant medical conditions that could interfere with the study may not benefit from this trial.

Why it matters

Potential benefit: If successful, this treatment could provide a non-invasive option for patients suffering from chronic TMD pain.

How similar studies have performed: While photobiomodulation has been FDA-approved for other types of pain, this specific application for TMD is novel and has not been extensively tested in prior studies.
