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 FILEThe 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 FILECompared 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 FILEThe 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 FILEWe 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 FILETemporomandibular 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)
OPEN FILEPhotobiomodulation therapy was effective in reducing nociceptive behavior and trigeminal nucleus neuronal activity after TMJ disc injury.
OPEN FILEThe 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.
OPEN FILEThese results suggest that low-level laser application is an effective tool for the treatment of patients with orofacial pain.
OPEN FILEBased on obtained data, we concluded that, compared to PDP, LLL treatment is effective to control pain associated with TMD.
