Efficacy of Photobiomodulation Therapy Using 980nm Versus 635nm Diode Lasers for Treatment of Myofascial Pain

National Institute of Laser Enhanced Sciences·interventional·Posted Jul 17, 2025·Updated Oct 23, 2025

In Brief

A clinical study evaluating Doctor smile 635nm For Arm 1 and Doctor smile 980 nm For Arm2 for Myofascial Pain Syndrome. Completed, enrolled 30 participants across 1 site.

Detailed Summary

This randomized controlled clinical trial aims to evaluate the efficacy of low-level laser therapy (LLLT) using two different diode laser wavelengths (980 nm and 635 nm) in the treatment of myofascial pain associated with temporomandibular disorders (TMD). The study compares pain reduction and muscle activity improvement using surface electromyography (sEMG) before and after laser application. Participants are randomly assigned to receive either 980 nm or 635 nm laser treatment twice per week for five weeks. The primary outcomes include pain intensity and functional mandibular movements, while secondary outcomes assess changes in sEMG recordings.

Interventions

Doctor smile 635nm For Arm 1device

Participants will receive low-level laser therapy using a diode laser with a wavelength of 635 nanometers. The treatment will be applied twice weekly for five weeks to the affected temporomandibular joint muscles to reduce myofascial pain and improve muscle function.

Doctor smile 980 nm For Arm2device

Participants will receive low-level laser therapy using a diode laser with a wavelength of 980 nanometers. The treatment will be applied twice weekly for five weeks to the affected temporomandibular joint muscles to reduce myofascial pain and improve muscle function.
