Evaluation of low-level laser therapy in the treatment of temporomandibular disorders
Photomedicine and Laser Surgery 2006;24(5): 637-41
Abstract
INTRODUCTION: Temporomandibular disorders (TMDs) are common causes of non-dental pain in the orofacial region, with symptoms such as pain, limited mouth opening and joint sounds like clicking or grinding. Physical therapy is important in treating TMD, aiming to reduce pain and inflammation and restore oral motor function. Recent physical therapies for TMD include photobiomodulation (PBM) therapy, therapeutic ultrasound (Th.US), electrophysical modalities, exercise and manual techniques.
MATERIALS AND METHODS: This study evaluated the effectiveness of PBM therapy and Th.US in managing TMDs. Sixty patients were divided with random assignment of patients equally into the two groups: Group I received PBM therapy, and Group II received Th.US. The patients were assessed for pain intensity using the Visual Analogue Scale, tender points and mouth opening using Vernier calipers. Statistical analysis was performed using SPSS software version 21.
RESULTS: This study showed a significant reduction in pain, increased mouth opening and fewer tender points in the PBM group (P < 0.005) compared to the Th.US group.
DISCUSSION: PBM therapy was found to be effective in reducing pain quickly and improving mouth opening, making it a valuable non-invasive option for managing TMDs.
