This systematic review and meta-analysis (PROSPERO registration; ref CRD 42020198921) aimed to govern photobiomodulation therapy (PBMT) efficacy in temporomandibular disorder (TMD). PRISMA guidelines and Cochrane Collaboration recommendations were followed. Differences in pain reduction assessment by qualitative measurement with visual analogue scale pain (VAS), pressure threshold (PPT) and maximum mouth opening (MMO) were calculated with 95% confidence intervals and pooled in a random effects model with a subgroup analysis, evaluating the role of follow-up duration. Heterogeneity was analysed using Q and I2 tests. Publication bias was assessed by visual examination of funnel plot symmetry. Qualitative analysis revealed 46% of the 44 included studies showed a high risk of bias. Meta-analysis on 32 out of 44 studies revealed statistically significant intergroup differences (SSID) for VAS (SMD = −0.55; 95% CI = −0.82 to −0.27; Z = 3.90 (p < 0.001)), PPT (SMD = −0.45; 95% CI = −0.89 to 0.00; Z = 1.97 (p = 0.05)) and MMO (SMD = −0.45; 95% CI = −0.89 to 0.00; Z = 1.97 (p = 0.05)), favouring PBMT compared to control treatment strategies. Sensitivity analysis revealed SSID (SMD = −0.53; 95% CI = −0.73 to −0.32; Z = 5.02 (p < 0.0001)) with low heterogeneity (T2 = 0.02; χ2 = 16.03 (p = 0.31); I2 = 13%). Hence, this review, for first time, proposed suggested recommendations for PBMT protocols and methodology for future extensive TMD research.

“…Depending on the type, the laser may be used in the area of soft and hard tissues. It is used, for instance, in orthodontics, in the treatment of temporomandibular joint dysfunctions and implantological rehabilitation [5][6][7][8][9]. Moreover, lasers have been demonstrated to support the treatment of snoring and sleep apnea, as well as periodontal diseases, e.g., peri-implantitis [10][11][12][13][14][15][16][17].…”

Purpose: to assess the effect of photobiomodulation (PBM) on human gingival fibroblast proliferation. Methods: The study was conducted using the primary cell cultures of human fibroblasts collected from systemically healthy donors. Three different laser types, Nd:YAG (1064 nm), infrared diode laser (980 nm), and prototype led laser emitting 405, 450, and 635 nm were used to irradiate the fibroblasts. Due to the patented structure of that laser, it was possible to irradiate fibroblasts with a beam combining two or three wavelengths. The energy density was 3 J/cm2, 25 J/cm2, 64 J/cm2. The viability and proliferation of cells were determined using the (Thiazolyl Blue Tetrazolium Blue) (MTT) test conducted 24, 48, and 72 h after laser irradiation. Results: The highest percentage of mitochondrial activity (MA = 122.1%) was observed in the group irradiated with the 635 nm laser, with an energy density of 64 J/cm2 after 48 h. The lowest percentage of MA (94.0%) was observed in the group simultaneously irradiated with three wavelengths (405 + 450 + 635 nm). The use of the 405 nm laser at 25 J/cm2 gave similar results to the 635 nm laser. Conclusions: The application of the 635 nm and 405 nm irradiation caused a statistically significant increase in the proliferation of gingival fibroblasts.

“…Ahrari et al [28] evaluated the effect of 810nm LLL in patients with myofascial pain one month after treatment and concluded that the effects of reducing the intensity of the pain and the increase in the mouth opening range were maintained. Some placebo-controlled studies indicated that LLLT was not effective compared to placebo [13,14,29]. In contrast, a recent study by Magri et al showed that there was no difference in the effects of active LLL or placebo on the decrease in pain intensity measured by VAS scale and sensory and affective pain components [29].…”

Introduction/Objective. Low-level laser therapy has been suggested as an alternative pain relief therapy in temporomandibular disorders patients. The aim of this study was to examine the effects of Low-level laser therapy on reducing pain intensity in temporomandibular disorders patients, compared to non-steroidal anti-inflammatory drugs. Methods. A total of 63 patients diagnosed with Research Diagnostic Criteria for Temporomandibular Disorders were divided into two groups. In the first group of 35 patients low-level laser therapy was applied three times a week, 15 treatment sessions during 5 weeks (Wavelength: 780 nm; Power density: 70 mW/cm2; Radiant energy: 4.2 J; Energy density: 4.2 J/cm2; Total treatment dose: 16.8 J/cm2;). The second group included 28 participants subjected to nonsteroidal anti-inflammatory drugs therapy (ibuprofen) during two weeks (first three days 3 ? 400 mg, remaining time 2 ? 400 mg per day). Pain was evaluated using 100 mm Visual Analog Scale, at the baseline, during therapy, two weeks and three months after treatments. Results. Statistically significant reduction of pain intensity was achieved both, in low-level laser therapy and in nonsteroidal anti-inflammatory drugs therapy groups and remained steady in the follow-up period of three months (p <0.01). Differences in Visual Analog Scale scores between observed groups were not statistically significant in each of the evaluation periods, (p = 0.375, p = 0.665, p = 0.52, respectively). Conclusion. The low-level laser therapy protocol applied in this research was efficient in reducing pain in temporomandibular disorders patients.
