Effect of diodes-laser silver arsenide-aluminium (Ga-Al-As) 904 nm on healing of experimental wounds.
Diodes-laser silver arsenide-aluminium (Ga-Al-As) 904 nm, which was used because of its properties of good tissue penetration and manageability, applied 5 min daily for 5 days at 3,000 Hz of frequency (energy density = 3 J), promoted healing of experimental wounds in rats from both a microscopic and histologic point of view. The same laser applied in these experimental conditions (number of rats was eight for each group) at the same energy density (3 J) for 10 min daily during 5 days at 1,500 Hz of frequency did not affect the experimental wounds.
