Efeitos da terapia a laser de baixa intensidade na evolução da cicatrização de lesões em humanos: a contribuição dos estudos experimentais in vitro e in vivo

Low-level laser therapy is an important method for the treatment of healing processes, and several experimental studies have been carried out in search of a greater understanding of its therapeutic possibilities. The objective of this study was to review pathogenetic aspects of soft tissue repair to better understand skin lesion healing and the role of low-intensity laser in the progression of tissue healing. This study consists of a concise review of scientific literature data on the use of low-level laser and its influence on wound healing. Many studies have extensively covered the effects of using laser radiation in tissues, describing its beneficial aspects in tissue healing. However, many unanswered questions demand research on the mechanism of action and on parameters of low-level laser use in different stages of wound repair to clarify how this method acts at a cell level in healing processes.Universidade Federal de Juiz de ForaUniversidade Federal FluminenseUFJF Centro de Biologia da Reprodução Laboratory of Immunopathology and Experimental PathologyUniversidade Federal de São Paulo (UNIFESP)UNIFESPSciEL
