Abstract Background: Low-level laser therapy (LLLT) has been verified effective in tooth-movement acceleration and pain alleviation during active orthodontic treatment, but its function remains inconclusive post-treatment. This systematic review aims to evaluate the effects of LLLT as an adjunct retention regimen following active orthodontic tooth movement (OTM).Methods: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Six databases (Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Pubmed, Scopus, ProQuest) were comprehensively searched for human and animal studies published till December 2019 and screened according to our eligibility criteria. The risk of bias was assessed based on the Cochrane Handbook for Systematic Reviews of Interventions and Systematic Review Center for Laboratory Experiment Tool. Two independent reviewers performed all procedures in duplicate. Any disagreement was resolved by discussion or consultation with a third reviewer.Results: A total of 394 records were identified from the initial search. Following screening, 15 full-text articles were reviewed for eligibility (ĸ>0.90), and ultimately, eight studies (three human studies and five animal studies) were included in this review. The key outcomes considered were ‘preventing tooth relapse’ and ‘rehabilitating root resorption’. Two controlled clinical trials (CCTs) and one animal study supported the preventive effects of LLLT on the relapse of post-orthodontic tooth positions. In contrast, two animal studies reported opposing findings. Regarding the rehabilitation of root resorption, evidence supported the reparative potential of LLLT in orthodontic force-induced root resorption. Overall, there was a high risk of bias among studies, except for one randomised controlled trial. Due to the substantial heterogeneity among studies in terms of their types, participants, designs, LLLT settings and variables of interest, it was not feasible to conduct a meta-analysis; therefore, a qualitative synthesis is presented.Conclusion: The quality of evidence for LLLT contributing to the maintenance of orthodontic outcomes or a better treatment prognosis remains low. There is considerable controversy over the effects of LLLT on orthodontic relapse. However, the use of LLLT after OTM has promising reparative effects for root resorption and is generally recommended.

Introduction: according to scientific literature, does low-power laser promote acceleration of tooth movements during orthodontic treatment? Objective: to systematize the ability of the low-power laser to accelerate tooth movements during orthodontic treatment. Material and methods: a systematic review was carried out, a search using Boolean search engines on the PubMed platform. The keywords used for were: orthodontic movement, orthodontic tooth movement, orthodontic, orthodontic treatment, low level laser therapy, low level laser, laser therapy and the combination between them. The included investigations dealt with the issue of acceleration of tooth movement during orthodontic treatment using low-power laser, were from journals indexed in PubMed, clinical trials, in English, and corresponded to articles published since 2000 to date. Assessment of risk of bias was performed. The variables analyzed were: main author, title, year, type of article, journal, country of research, and whether the articles show that low-power laser increases tooth movement during orthodontic treatment. Results: 60% of the included studies conclude that the low-power laser accelerates tooth movement during orthodontic treatment, 30% of these did not find significant changes in relation to the groups studied with those of control and 10% resulted in dubious conclusions. Conclusions: although the results are encouraging due to the trend in which the low-power laser does accelerate orthodontic movements, the presence of a higher number of randomized clinical studies would be necessary for a specific clarification of the benefits that this therapy brings to the patient. sector.

Purpose This systematic review aimed to analyze the effects of low-level laser therapy (LLLT) on the severity of tinnitus when compared to no therapy or other modalities of therapies. Method A systematic review protocol was registered at the International Prospective Register of Systematic Reviews (PROSPERO) under the Registration Number CRD42019119376. A search was performed in each of the following databases: EMBASE, LILACS, PubMed, Science Direct, Scopus, Web of Science, Google Scholar, and ProQuest. The inclusion criteria consisted of studies in adults over 16 years of age, randomized clinical trials in which subjects presented chronic (≥ 6 months) and subjective tinnitus (unilateral or bilateral) as well as with or without bilateral sensorineural hearing loss, and studies that used only LLLT for treatment of tinnitus compared to no-therapy group or other modalities of therapy. No language or time restrictions were stipulated. The references were managed by Endnote Web and Rayyan QCRI. Results After the screening process, seven studies remained that attained the eligibility criteria. Regarding the risk of bias, only one study was categorized as low risk of bias; the six remaining studies were classified as moderate risk of bias. The seven included studies mainly assessed the LLLT effects on tinnitus by Visual Analogue Scale, Tinnitus Handicap Inventory, pitch and loudness matching, minimum masking level, and pure-tone audiometry. All the seven selected studies found different degrees of significant results regarding tinnitus severity; however, there was no consensus among the results. Conclusion Even though the LLLT showed positive effects in the tinnitus severity in some studies, it is not possible yet to make any recommendation over its uses for the treatment of tinnitus severity.

ObjectivesLow-level laser therapy (LLLT) is not recommended in major knee osteoarthritis (KOA) treatment guidelines. We investigated whether a LLLT dose–response relationship exists in KOA.DesignSystematic review and meta-analysis.Data sourcesEligible articles were identified through PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature, Physiotherapy Evidence Database and Cochrane Central Register of Controlled Trials on 18 February 2019, reference lists, a book, citations and experts in the field.Eligibility criteria for selecting studiesWe solely included randomised placebo-controlled trials involving participants with KOA according to the American College of Rheumatology and/or Kellgren/Lawrence criteria, in which LLLT was applied to participants’ knee(s). There were no language restrictions.Data extraction and synthesisThe included trials were synthesised with random effects meta-analyses and subgrouped by dose using the World Association for Laser Therapy treatment recommendations. Cochrane’s risk-of-bias tool was used.Results22 trials (n=1063) were meta-analysed. Risk of bias was insignificant. Overall, pain was significantly reduced by LLLT compared with placebo at the end of therapy (14.23 mm Visual Analogue Scale (VAS; 95% CI 7.31 to 21.14)) and during follow-ups 1–12 weeks later (15.92 mm VAS (95% CI 6.47 to 25.37)). The subgroup analysis revealed that pain was significantly reduced by the recommended LLLT doses compared with placebo at the end of therapy (18.71 mm (95% CI 9.42 to 27.99)) and during follow-ups 2–12 weeks after the end of therapy (23.23 mm VAS (95% CI 10.60 to 35.86)). The pain reduction from the recommended LLLT doses peaked during follow-ups 2–4 weeks after the end of therapy (31.87 mm VAS significantly beyond placebo (95% CI 18.18 to 45.56)). Disability was also statistically significantly reduced by LLLT. No adverse events were reported.ConclusionLLLT reduces pain and disability in KOA at 4–8 J with 785–860 nm wavelength and at 1–3 J with 904 nm wavelength per treatment spot.PROSPERO registration numberCRD42016035587.
