In this work, we analyze the clinical alterations and histological modifications in patients with not infect ulcers of pressure, submitted to the Laser irradiation GaAs (wavelength 904 nm, doses 3 J/cm², during 1 minute and prompt application) during 5 days consecutive and as a group radiated during 15 days alternating. In the clinical evaluation after the laser irradiation observed presence of exudation, granulation tissue and points of bleed after the third day of irradiation. The computerized morph quantitative analysis demonstrated that submitted to the laser irradiation during the 15 days busy area for the 4115,922 vases was of µm², and in the radiated ones during 5 4348,253 days of µm², both in a 0,25 area of cm² of derma. The gotten results suggest that this therapeutically one was efficient as to assist in the processes of tissue regeneration in the patients treated in the research.
