An interventional study of Low Level Laser Therapy and Dietary Supplement in Myalgia of Mastication Muscle, sponsored by Karadeniz Technical University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 15 Years and older. Per ClinicalTrials.gov, last updated 2026-05-15.
Sponsored by Karadeniz Technical University · Not applicable, Interventional, and Treatment
This clinical study aimed to evaluate the effectiveness of low-level laser therapy in patients with temporomandibular disorders (TMD), specifically disc displacement with reduction and myalgia. The study compared laser therapy with a soft diet approach to determine whether laser treatment provides additional benefits in reducing pain and improving jaw function

Diagnosis of disc displacement with reduction (DDwR) and myalgia according to DC/TMD criteria Presence of temporomandibular joint pain and functional limitation Patients aged 18 years and older No previous temporomandibular joint (TMJ) treatment Absence of systemic diseases Willingness to participate and provide informed consent
Exclusion Criteria:
History of previous TMJ treatment (e.g., conservative or surgical treatment) Congenital or inflammatory joint disease Severe systemic diseases Edentulous patients Children and adolescents in the active growth period Acute trauma history involving the TMJ region Inability or unwillingness to complete follow-up visits
Participants in this group received low-level laser therapy applied to the temporomandibular joint region according to the predefined treatment protocol. Laser therapy was administered for 2 minutes per joint over 9 treatment sessions. Patients were also advised to follow a soft diet during the treatment period.
Other: Low Level Laser Therapy
Soft Diet Group: Participants in this group did not receive laser therapy and were instructed to follow a soft diet during the study period. This group served as the comparison group for evaluating treatment outcomes.
Other: Dietary Supplement
Participants received low-level laser therapy applied to the temporomandibular joint region in addition to soft diet recommendations. Treatment was performed in 9 sessions according to the predefined laser protocol. Participants followed a soft diet regimen without receiving laser therapy and served as the comparison group.
Participants in this group did not receive laser therapy and were instructed to follow a soft diet during the study period. This group served as the comparison group for evaluating treatment outcomes.
Change in temporomandibular pain intensity measured by the Visual Analog Scale (VAS) from baseline to the end of treatment and follow-up
Change in temporomandibular pain intensity was assessed using the Visual Analog Scale (VAS) from baseline to the end of treatment and follow-up. The Visual Analog Scale ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Higher scores represent greater pain severity.
