Effect of low-level laser application in conjunction with splint therapy for management of temporomandibular joint disorders

Abstract

Objective: This Randomized clinical trial was conducted to assess the value of using LLLT (Low level Laser Therapy) plus Splint therapy in comparison with using splint therapy alone for treatment of TMDs. Subject & Methods: Twenty-six patients with TMDs were divided into 2 equal groups: Group I was the trial group where 5 LLLT sessions were done for all patients on a period of 5 weeks in conjunction with splint therapy, group II as a control group (splint therapy only). Pain level, maximum mouth opening, lateral excursions, clicking sounds and disc position were recorded and analyzed statistically. Results: There was a non-statistically significant difference after 6 months concerning pain level, maximum mouth opening, lateral excursions and disc position However there was improvement regarding pain level initially for the trial group. Conclusion: LLLT proved to be helpful with encouraging effect in alleviating pain during of treatment acute phase of TMDs, however, it has no significant effect on range of motion or disc position.
