Objective: To analyze the effects of low-level laser therapy (GaAs, 904 nm) for bone repair on tibial fractures in rats.
Methods: Forty rats were divided into four groups of 10 animals: control group without fracture (CG); fracture group without treatment (EG II); fracture group treated with laser at 10 J/cm(2) (EG III); and fracture group treated with laser at 15 J/cm2 (EG IV). The fracture was produced surgically and the treatment lasted 45 days, done on alternate days.
