Laserterapia de baixa potência e sua relação no processo de cicatrização : uma revisão sistemática de literatura.

Abstract

The objective of this systematic review of the literature was to identify the interaction of the low power laser and the repair of tissue healing in standardized wounds in the rat animal model. Experimental studies that adopted low-level laser therapy for the treatment of acute wounds in rats with induced injuries were selected. The Pubmed, Scielo and Portal of CAPES journals databases were used using the following descriptors: Low-level laser therapy; Low power laser; Wound healing; and English: laser therapy and healing. Sixteen studies were included in the systematic review. All studies performed analysis through histological cuts of scars. Some studies have shown a reduction in the intensity of the inflammatory process and a better organization of collagen fibers in irradiated groups. Low-level laser therapy has shown good response in tissue repair in some studies, but in others it has not demonstrated beneficial effects of laser therapy on the healing process.
