Oral Mucositis and Laser Therapy Associated With Photodynamic Therapy

"Two days before the laser treatment, the side of the oral cavity chosen for the experimental treatment was pigmented with aqueous solution of 0.005% methylene blue. A ball of sterile cotton was soaked in the dye solution and placed in the center of the lesion. Photosensitizer remained in the place for 5 minutes (pre-irradiation period). Then, to activate the dye, the lesion was irradiated with red light (InGaAlP / phosphide and Indium, Gallium and potassium).~From the 3rd to the 10th day was carried out only laser therapy. For laser therapy was first used infrared emitter laser unit with active medium AsGaAl (Gallium Arsenide and Aluminium). Then, we used the red emitter, whose active medium was the InGaAlP (phosphide and Indium, Gallium and Potassium)."

Two days before the laser treatment, the lesion of the side of the oral cavity chosen for the control treatment was treated with ball of sterile cotton soaked in distilled water and the laser unit placed on the lesion without activation of the light. From the 3rd to the 10th day was carried out laser therapy. For laser therapy was first used infrared emitter laser unit with active medium AsGaAl (Gallium Arsenide and Aluminium). Then, we used the red emitter, whose active medium was the InGaAlP (phosphide and Indium, Gallium and Potassium).
