AbstractMuscle injuries are frequent, both in the practice of exercises and in the work environment, and after the injury, healing begins. The inflammatory phase of muscle healing is accompanied by an increase in the production of reactive oxygen species (ROS), and a reduction in the antioxidant activity of defense enzymes. This imbalance between both can generate oxidative stress, which can cause oxidative damage by directly affecting vital cellular constituents, such as lipids, proteins and DNA, in addition to interfering negatively in the muscle cells differentiation . Therefore, substances or therapies that stimulate antioxidant repair and defense are crucial to keep the levels of free radical production low, and to minimize factors that delay or prevent tissue recovery, among these therapies photo biomodulation has stood out. The objective of this literature review is to clarify the FBM effect on oxidative stress and muscle repair. Therefore, a search was carried out in the databases of Pubmed, Scielo, Lilacs and PEDro, using the keywords “Photo biomodulation”, “low power laser”, “muscle repair”, “oxidative stress”, and in English were ”Photo biomodulation”, “low level laser therapy”, “muscle repair” and “oxidative stress”. The texts that addressed the research topic, published between 2000 and 2020, were chosen. After analyzing the articles, it was possible to observe that photo biomodulation, despite presenting a great variety of parameters, moment of application and irradiation protocol found in the literature, shows beneficial results in the repair muscle and in the reduction of oxidative stress and fatigue markers. Keywords: Low-Level Light Therapy. Oxidative Stress. Edema. ResumoLesões musculares são frequentes, tanto na prática de exercícios como no ambiente de trabalho, sendo que após a lesão, inicia a cicatrização. A fase inflamatória da cicatrização muscular é acompanhada do aumento da produção de espécies reativas de oxigênio (ERO) e uma redução da atividade antioxidante das enzimas de defesa. Este desequilíbrio entre ambos pode gerar o estresse oxidativo, que leva a danos e atingi diretamente constituintes celulares vitais, como lipídios, proteínas e DNA, além de interferir negativamente na diferenciação das células musculares. Portanto, substâncias ou terapias que estimulem a reparação e a defesa antioxidante são cruciais para manter os níveis de produção de radicais livres baixos, e minimizar os fatores que atrasam ou impedem a recuperação do tecido, dentre estas terapias a fotobiomodulação tem se destacado. O objetivo da presente revisão de literatura é esclarecer o efeito da FBM sobre o estresse oxidativo e o reparo muscular. Sendo assim, realizou-se uma pesquisa nas bases de dados da Pubmed, Scielo, Lilacs e PEDro, utilizando as palavras-chave “Fotobiomodulação”, “laser de baixa potência”, “reparo muscular”, “estresse oxidativo”, e em inglês foram “photobiomodulation”, “low level laser therapy”, “muscle repair” e “oxidative stress”. Foram escolhidos os textos que abordavam o tema da pesquisa, publicados entre 2000 e 2020. Analisando os artigos foi possível observar que a fotobiomodulação apesar de apresentar grande variedade de parâmetros, momento de aplicação e protocolo de irradiação encontrados na literatura, mostra resultados benéficos no reparo muscular e na diminuição de marcadores do estresse oxidativo e fadiga.

Introduction: Finding a method to decrease orthodontic treatment time has been a concern for several authors. This study evaluated, clinically and radiographically, the influence of low-level laser therapy on the rate of orthodontic movement and dental tissue integrity. Methods: The sample included 11 individuals with class I malocclusion, requiring extraction of 4 first premolars. Gallium aluminum arsenide diode laser with a wavelength of 780 nm was used once a month during retraction mechanics, to irradiate the maxillary and mandibular canines on one side and compare them with the nonirradiated contralateral side, after spring activation, until canine retraction was completed. This was followed by movement measurement. Periapical radiographs were used to check for possible modifications in the supporting tissues and root surface of the displaced canines. Results: No differences in the rate of tooth movement were found between the irradiated and nonirradiated side on both dental arches. There was no resorption of the root and/or alveolar bone crest, maintaining the integrity of these tissues. Conclusions: Low-level laser therapy did not promote an increment on the rate of tooth movement and did not cause greater root and alveolar bone crest resorption than on the nonirradiated side with the used protocol.

Abstract Objectives: To describe the microscopic pulpal reactions resulting from orthodontically induced tooth movement associated with low-level laser therapy (LLLT) in rats. Materials and Methods: Forty-five young male Wistar rats were randomly assigned to three groups. In group I (n = 20), the maxillary right first molars were submitted to orthodontic movement with placement of a coil spring. In group II (n = 20), the teeth were submitted to orthodontic movement plus LLLT at 4 seconds per point (buccal, palatal, and mesial) with a GaAlAs diode laser source (830 nm, 100 mW, 18 J/cm2). Group III (n = 5) served as a control (no orthodontic movement or LLLT). Groups I and II were divided into four subgroups according to the time elapsed between the start of tooth movement and sacrifice (12 hours, 24 hours, 3 days, and 7 days). Results: Up until the 3-day period, the specimens in group I presented a thicker odontoblastic layer, no cell-free zone of Weil, pulp core with differentiated mesenchymal and defense cells, and a high concentration of blood vessels. In group II, at the 12- and 24-hour time points, the odontoblastic layer was disorganized and the cell-free zone of Weil was absent, presenting undifferentiated cells, intensive vascularization with congested capillaries, and scarce defense cells in the cell-rich zone. In groups I and II, pulpal responses to the stimuli were more intense in the area underneath the region of application of the force or force/laser. Conclusions: The orthodontic-induced tooth movement and LLLT association showed reversible hyperemia as a tissue response to the stimulus. LLLT leads to a faster repair of the pulpal tissue due to orthodontic movement.
