Abstract in Portuguese
Introdução: este estudo avaliou o efeito do laser vermelho de baixa potência na viabilidade de retalhos cutâneos randômicos em ratos. Métodos: 40 ratos Wistar foram divididos em 4 grupos, aleatoriamente, onde 1 grupo foi utilizado como controle (G1) e os demais foram irradiados com laser de 670 nm, com 2,14 (G2), 5,36 (G3) e 20,36 J/cm2 (G4), respectivamente. Resultados: o G1 apresentou 49,35% da área do retalho necrosada, G2 39,14%, G3 47,01% e G4 29,17%. À análise estatística obtivemos diferença significativa apenas quando comparamos G4 com o G1 (p < 0,001). Conclusão: o LBP vermelho (20,36 J/cm2) é capaz de incrementar a viabilidade dos retalhos cutâneos randômicos em ratos

Abstract in English
Introduction: This study assessed the effects of different LLLT doses on randomic skin flap rats. Methodology: 40 wistar rats were divided in four groups. The control group (CG) was not irradiated. The experimental groups were irradiated with different fluency: group 2 (G2) with 2,14 J/cm²; group 3 (G3) 5,36 J/cm² and group 4 (G4) 20,36 J/cm². The necrosis area was evaluated in the seventh postoperative day. Results: The CG shows 49,35% of necrosis area in the skin flap; G2, 39,14%; G3, 47,01% and G4, 29,17% respectively. There was a significantly difference when G4 was compared with CG`s skin flap necrosis area. Conclusion: Red LLLT with increases the survival in randomic skin flap rats
