Abstract Introduction: Treatments for rheumatoid arthritis (RA) and osteoarthritis (OA) can reduce, modulate inflammation, and reduce deformities. Low-Level Laser Therapy is a biomodulator and may aid in the clinical picture of these conditions. Objective: To analyze the parameters most frequently used to determine the responses of patients with RA and OA in controlled and uncontrolled clinical trials. Method: This is a systematic review with search of articles in English, Portuguese and Spanish in PUBMED, SCOPUS, LILACS and Web of SCIENCE, of articles published between 2006 and 2018. MeSH terms were used. Inclusion criteria: evaluation of LLLT in the evaluations, evaluation and evaluation of the period, controlled and uncontrolled clinical trials, full publications. The base date of the energy dosimetry and the analysis of mean, median and mode of energy per point and energy per treatment. Results: Three articles on RA and 16 on OA were included in this study. Regarding dosimetry, it was one of the most recent of the pain, being this one with a greater energy dose. In OA, most of the articles presented are of importance, with variability in the dosage applied. Conclusion: There are several reports for patient studies purposes, mainly with doses of 6 J per point and 48 J. In the joints affected with OA and AR, it would be important to publish more scientific articles with better methodological quality and description of dosimetry.

AIM: Conducting a systematic review of randomized clinical trials focusing on the efficacy of LLLT on pain control in patients with TMD, diagnosed by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). MATERIAL AND METHODS: Search was performed at PubMed/MEDLINE database with the terms: (1) “Laser AND temporomandibular disorders”; (2) “Laser AND temporomandibular disorders AND RDC/TMD”; (3) “Low-level laser therapy AND temporomandibular disorders”; (4) “Low-level laser therapy AND temporomandibular disorders AND RDC/TMD”; (5) “Low-level laser therapy AND temporomandibular joint dysfuntion syndrome”; (6) “Low-level laser therapy AND temporomandibular joint dysfuntion syndrome AND RDC/TMD”; (7) “Laser AND temporomandibular joint dysfuntion syndrome” (8) “Laser AND RDC/TMD”; (9) “Low-level laser therapy AND RDC/TMD”. Inclusion criteria: articles need to be randomized clinical trial performed in humans; evaluate the effect of LLLT in the treatment of TMD diagnosed by the use of RDC/TMD; published in English or Portuguese in the last 10 years. Protocol studies and pilot studies were excluded. RESULTS: Ten studies were included. The type of laser used was Gallium Aluminum Arsenide (GaAlAs) diode, with exception of 1 paper, which used super pulsed Gallium Arsenide laser. Eight studies reported decreased in pain levels, in two articles there was no statistically significant difference between test and placebo groups. CONCLUSION: In most studies, LLLT was effective in pain remission, but there is no standardization in parameters like wavelength, output power and frequency. Studies with more complex experimental designs, standardized diagnostic criteria for TMD and defined protocols for the use of LLLT are needed to determine its efficacy in the treatment of TMD.
