Abstract

The study aimed to evaluate the pain relief and mouth opening improvement results of low- level laser therapy (LLLT) in the treatment of TMDs. A randomized controlled trial was conducted on 44 patients diagnosed with TMD myalgia according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Patients were divided into 2 groups. Group 1 received diode laser at a wavelength of 660 nm, 2 sessions a week, for a total of 10 sessions. Group 2 were instructed to wear stabilization splint at night, 8 hours/day for 2 months. Both groups received education regarding TMD management, with recommendations for modifying oral behaviors and performing mandibular exercises, cold compress, warm compress 2 times/day for 2 months. Evaluations were conducted at baseline (T0), 2 weeks (T2), 4 weeks (T4), 12 weeks (T12), and 24 weeks (T24) post-treatment to assess the Visual Analog Scale (VAS), the number of tender points in the masticatory muscles, maximum mouth opening. The VAS scores before and after treatment were dissimilar in group l and group 2 (p < 0.05). The VAS score were comparable between the two groups post treatment (p > 0.05). The maximum mouth opening significantly improved in both groups at the 24-week follow-up (p < 0.05). Low-level laser therapy (LLLT) demonstrated efficacy in pain reduction and mouth opening improvement comparable to that of occlusal splints in the management of TMDs.
