Analysis of laser therapy and assessment methods in the rehabilitation of temporomandibular disorder: a systematic review of the literature
Further studies are needed, especially randomized clinical trials, to establish the exact dose and ideal parameters for low-level laser therapy and define the best assessment tools in this promising field of research that may benefit individuals with signs and symptoms of TMD. Key words: Temporomandibular joint disorder, Electromyography, Laser
OPEN FILEComparative evaluation of the early effects of the low-level laser therapy versus intra-articular steroids on temporomandibular joint acute osteoarthritis in rats: A histochemical, molecular and imaging evaluation.
The aim of the study was to evaluate the early effects of low-level laser therapy (LLLT) vs intraarticular (IA) corticosteroids (CS) on acute temporomandibular joint osteoarthritis (TMJOA).
OPEN FILELaser Therapy and Occlusal Stabilization Splint for Temporomandibular Disorders in Patients With Fibromyalgia Syndrome: A Randomized, Clinical Trial.
Compared with baseline, the laser treatment showed significant improvements on several outcomes, including the VAS, P < .001; WPI, P = .003; and SSS, P = .001. Overall, the study found an average improvement in symptoms from baseline of 21% , P < .001, based on the PGIC. Conclusions • Laser therapy or an occlusal stabilization splint can be an alternative therapeutic treatment for reducing pain symptoms and the clicking sound for TMDs in patients with FMS.
OPEN FILEIntraoral photobiomodulation diminishes pain and improves functioning in women with temporomandibular disorder: a randomized, sham-controlled, double-blind clinical trial : Intraoral photobiomodulation diminishes pain in women with temporomandibular disor
The findings demonstrate that intraoral photobiomodulation involving super-pulsed laser (905 nm) combined with red (640 nm) and infrared (875 nm) light-emitting diodes diminishes pain and improves functioning but does not exert an influence on mandibular range of motion in women with temporomandibular disorder.
OPEN FILELow-Level Laser Therapy for Temporomandibular Disorders: A Systematic Review with Meta-Analysis.
We systematically reviewed randomized controlled trials (RCTs) of the effect of low-level laser therapy (LLLT) versus placebo in patients with temporomandibular disorder (TMD). A total of 31 RCTs were included. Total modified Jadad scale scores showed that the methodological quality was high in 30 studies and low in 1 study. Combining data from all clinically heterogeneous studies revealed positive effects of LLLT on pain relief, regardless of the visual analogue scale (VAS) score or the change of VAS score between the baseline and the final followup time point, while dosage analyses showed discrepant results about the effects of high or low doses for patients with TMD. Follow-up analyses showed that LLLT significantly reduced pain at the short-term follow-up. Temporomandibular joint function outcomes indicated that the overall effect favored LLLT over placebo.
OPEN FILELow Level Laser Therapy in the Treatment of Temporomandibular Joint Arthritis: Questions and Answers
Temporomandibular disorder (TMD) is a collective term for a number of clinical signs and symptoms involving masticatory muscles, temporomandibular joint (TMJ) and associated structures (De Leeuw, 2008) Some studies show that 3-7% of the adult population seek care for TMJ pain and dysfunction (Carlsson, 1999) and the range of symptom occurrence to be between 16%and 59% and the range of clinical signs to be between 33% and 86%. Among individuals with TMJ disorders 11% had symptoms of TMJ arthritis. (Mejersjo & Hollender, 1984; Tanaka, Detamore et al., 2008) There is disagreement between the classification of degenerative joint disease as presented by the American Association of Orofacial Pain and the RCD/TMD( Research Diagnostic Criteria of Temporomandibular Disorders) (LeResche, 1997)

Photobiomodulation therapy was effective in reducing nociceptive behavior and trigeminal nucleus neuronal activity after TMJ disc injury.
OPEN FILEEfficacy of Low-Level Laser Therapy in the Treatment of Temporomandibular Myofascial Pain
The findings from this systematic review showed that LLLT seems to be effective in reducing pain in patients with temporomandibular myofascial pain with moderate-quality evidence.
