The effect of low-level laser therapy on functional improvements in the temporomandibular joints: randomized clinical trial

Introduction: Temporomandibular disorders (TMD) - recognized as the most common chronic orofacial pain condition significantly impacts individuals’ quality of life and social coexistence. Therefore, this study aimed to analyze effects low-level laser therapy (LLLT) on functional improvements in temporomandibular joints (TMJ). Method: The research was carried out at Universidade Federal do Piauí 32 young adults with signs symptoms TMD, who were divided into intervention group (IG) control (CG). IG administered LLLT application directly TMJ. While both groups subjected same procedures, for CG, device turned off. Results: mean age participants 21.87 ± 2.4 years, a predominance females (87.5%) over males (12.5%). Homogeneity observed between CG concerning presence from palpation. decrease musculature relevant, emphasis IG, which used LLLT. Moreover, there an increase participants, rated scale their “0” (no pain), presented increased measures joint mobility mandible cervical spine, relief painful symptoms, by breaking pain-spasm-pain cycle. Conclusion: promotes significant reduction palpation, improves range motion, generates immediate long-lasting benefits.
