Efficacy of the LED Red Light Therapy in the Treatment of Temporomandibular Disorders: Double Blind Randomized Controlled Trial

Abstract

Background. Temporomandibular dysfunction syndrome (TMD) is a common disease among dental patients. It occurs as a consequence of malfunction of the tempromandibular and/or surrounding facial muscles. LED red light therapy is not been well established, and it is important to find out the role of this technique in the treatment of temporomandibular disorders. Aim of the Study. To evaluate the efficacy of the LED red light in the treatment of the tempromandibular dysfunction syndrome. Material and Methods. Fifty students of the College of Dentistry/University of Baghdad with myofacial pain associated with Tempromandibular Disorder volunteered to participate in this study and be evaluated during both treatment and follow-up periods. They were 40 (80%) females and 10 (20%) males. Patients were divided into 2 groups: Group A treated by TenDlite® Medical Device model 204 with a LED’s of wavelength 660 nm (red light) and Group B given placebo (no treatment at all) by just putting the TenDlite device near the tender points without battery and turning ON the device. Results. The changes in the pain value and number of the tender muscles in both groups were highly significant, only placebo group less but with no significant differences. Conclusions. This study showed that red LED therapy could be useful in improving patient’s symptoms regarding pain, clicking, and number of tender muscles. In addition, this study showed the importance of the psychological part of treatment of those patients. This trial is registered with TCTR20190406002.

Role of Photobiomodulation Therapy in Modulating Oxidative Stress in Temporomandibular Disorders. A Systematic Review and Meta-Analysis of Human Randomised Controlled Trials

“…The majority of the included studies reported a combination of one or more of the following symptoms upon their first visit to the hospital; myofascial pain in 13 studies [59,67,68,72,76,78,[80][81][82]94,97,98,100], orofacial pain in nine studies [58,69,71,[73][74][75]87,96,99], MPDS in nine studies [66,67,78,81,[96][97][98][99][100], limited MM in five studies [58,66,75,87,91], disc displacement in five studies [57,60,64,70,97], whereas capsulitis/synovitis [57,60,64] and limited mouth opening [77,84,89] were in three studies each. Two studies presented with TMJ clicking [87,…”

“…Pain was considered as the most commonly reported functionality problem in the majority of the included studies [57][58][59][60][61][62][63][64][65][66][67][68][69][71][72][73][74][75][76][78][79][80][81][82][84][85][86][87][88][89][90][92][93][94][95][96][97][98][99][100]. Five studies reported limited MM [58,66,75,84,87,89,91,98], whereas the other commonly associated functionality problems reported in the included studies were TMJ clicking [87,…”

“…Out of 44 studies, 23 were conducted in Brazil [57,[60][61][62]64,66,68,[73][74][75][76]79,80,82,83,[88][89][90]93,95,97,98,100], five studies each in Iran [63,67,77,84,91] and Turkey [58,69,71,78,81], three studies in India [85,96,99] and one study each in the following countries: Czech Republic [59], Italy [70], Austria [65], UK [72] U.A.E. [87], Saudi Arabia [92] and Iraq [94] (Table S1).…”

“…Out of 44 studies, 20 evaluated the effect of PBMT compared to a placebo (sham PBMT) group [57,58,[60][61][62][63][64][65]71,77,80,81,83,85,87,90,[92][93][94]100]. Two studies assessed different PBM therapeutic doses [59,88].…”

Photobiomodulation with cluster does not present superior results to placebo in young people with chronic non-specific lumbar pain

“…In isolation, LLLT has been shown to be effective, both in clinical and experimental studies in several conditions helping to control pain, reduce the inflammatory process and speed-up tissue repair [18][19][20][21], but not without controversial outcomes [22]. Such effects have also been observed for LED therapy [23,24].…”
