“…Consequently, 44 out of 51 full text articles were included and analysed in the present systematic review . Furthermore, 32 out of 44 studies qualified for a meta-analysis [57,58,[60][61][62][63][64][65][66][67][68][69][70][71][72][73][74]77,78,81,[83][84][85][86]88,89,91,[95][96][97]99,100] (inter-reviewer agreement, κ = 1).

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.

“…Temporomandibular disorder diagnostic method for almost all studies was RDC/TMD; only three used DC/TMD . TMD diagnostic englobed myofascial pain (groups I.a and I.b) mentioned in sixteen studies, arthralgia (III.a) in ten studies, osteoarthritis (III.b) in six studies, osteoarthrosis (III.c) in four studies and disc displacement (II.a, II.b and II.c) in four studies.…”

Objectives The aim of this systematic review (SR) was to answer the following question: “In adult patients with temporomandibular disorder (TMD)‐related pain, what is the placebo or nocebo effect of different therapies?” Methods A SR was performed with randomised clinical placebo‐controlled trials on diagnosed painful TMD studies from five main databases and from three grey literature. Studies included must have sample older than 18 years, with painful TMD, which diagnosis was done by Research Diagnostic Criteria (RDC/TMD) or Diagnostic Criteria (DC/TMD). Results Out of 770 articles obtained, 42 met the inclusion criteria for qualitative and 26 for quantitative analysis. Meta‐analysis indicated mean variation on pain intensity for placebo therapy was higher on laser acupuncture with 45.5 mm point reduction, followed by avocado soya bean extract with 36 mm and amitriptyline 25 mg with 25.2 mm. Laser showed a 29% of placebo effect, as well medicine with 19% and other therapies with 26%. Possible nocebo effect of 8% pain increase was found for intra‐articular injection of Ultracain. Conclusions Based on the available data, the placebo response could play a major effect on TMD pain management and may be responsible from 10% to 75% of pain relief. Laser acupuncture, avocado soya bean and amitriptyline promoted the higher placebo effect. Possible nocebo effect was found only for Ultracain injection with 8%. Clinical Relevance Clinicians could apply such evidence to optimise pain management and judgement about treatment efficacy, and researches may find it useful when designing their investigations.
