RESUMO

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
