Background: The effect of laser on reducing inflammation has always been considered. The aim of this study was to evaluate the clinical studies on the effect of using low-power lasers on the production and activity of proinflammatory cytokines such as IL-1, IL-6, and TNF-α.Methods: This study is a systematic review of Google Scholar, PubMed, and SCOPUS database articles which was conducted from 1990 to 2021. All information was categorized in a table.Results: In the review conducted in the mentioned databases and according to the considered time period, 239 articles related to the searched terms were found through the abstract. After removing duplicate titles and articles, 31 articles were selected and a more detailed review by the evaluation team yielded 16 articles. The full texts of these 16 articles were reviewed. For the final selection, 13 articles met the inclusion criteria and included the objectives of the present study.Conclusion: Understanding the true mechanisms of low-level laser therapy (possible photochemical, photomechanical, and photobiological changes) and examining the relationship between cellular effects and changes in cytokines and clinical phenomena require numerous controlled clinical trials to develop an effective treatment protocol.

Background: New antimicrobial procedures are of significant importance to emerging species of bacteria and viruses. The objective of this systematic review study was to identify the efficacy, safety, and application of UV light in the disinfection of dental environments, instruments, and materials. Methods: In this systematic review article, the authors performed an electronic search of Google Scholar, Pubmed, and SCOPUS databases to retrieve related English language articles published between the years 1990 and 2020. At first, the selected articles were reviewed by screening their titles and abstracts and ultimately by full text. Results: 35 articles were considered relevant and included in this study. Fifteen studies were related to the antibacterial efficacy of UV radiation on various bacterial, fungal, and viral species. Two studies applied UV irradiation for the disinfection of titanium implants. Sixteen articles suggested the application of UV radiation for disinfection of dental impressions, toothbrushes, N95 masks, removable prostheses, acrylic resins, and surfaces. Furthermore, one study strongly suggested using eye protection appliances while working with UV radiation, and one study claimed that UVB radiation led to oral and skin cancer while this risk is higher for oral cancer. Conclusion: UV radiation with a specific dose and a duration effectively kills viruses, bacteria, and fungi for disinfection in dental procedures, which includes dental tools and materials such as toothbrushes, dental implants, impression materials, removable dentures, and dental environment. However, the principles of protection are emphasized to reduce its harmful effects on the eyes and skin.
