Laser Therapy in the Tissue Repair Process: A Literature Review

Objective: Carry out a literature review on the use of laser therapy in the tissue repair process and address the different lasers and parameters used by the authors. Methods: A review was carried out of the literature from 1960 to 2008 in the Lilacs, Medline, and PubMed databases using the following key words: Laser Therapy, Wound Healing, and Tissue repair. Results: the most frequently used types of laser are helium neon (HeNe) lasers and diode lasers, including gallium-aluminum-arsenium (GaAlAs), arsenium-gallium (AsGa), and indium-gallium-aluminum-phosphide (InGaAlP) lasers. However, implementation of different protocols was found, with different materials and different activating wavelengths, thus making it difficult to compare results and choose the parameters of treatment. Conclusions: the majority of authors report that laser therapy speeds up the process of tissue repair, but further studies are suggested to determine the best parameters to be used.Fac Tecnol & Ciencias, Physiotherapy Dept, BR-45020510 Vitoria Da Conquista, BA, BrazilUniv Camilo Castelo Branco, Physiotherapy Dept, São Paulo, BrazilUniversidade Federal de São Paulo, Physiotherapy Dept, São Paulo, BrazilUniversidade Federal de São Paulo, Physiotherapy Dept, São Paulo, BrazilWeb of Scienc
