Effects of Superpulsed Low-level Laser Therapy on Temporomandibular Joint Pain
This randomized double-blind study evaluated the effectiveness of superpulsed low-level laser therapy (SLLLT) compared with ibuprofen and placebo in managing temporomandibular joint disorders (TMD) related to disc displacement without reduction or osteoarthritis. A total of 99 patients were divided into three groups: SLLLT (39 patients, 10 sessions), ibuprofen (30 patients, 800 mg twice daily for 10 days), and sham laser placebo (30 patients). Pain intensity (VAS) and mandibular function were assessed throughout treatment and follow-up. Results showed that SLLLT significantly reduced pain compared with both ibuprofen and placebo from day 5 onward (P=0.0001). Additionally, improvements in active and passive mouth opening and lateral motions were more evident in the SLLLT group after 1 month (P=0.0001). Overall, SLLLT demonstrated superior efficacy in pain relief and functional recovery, proving its effectiveness as a noninvasive therapy for TMD.
