Avaliação da ação da laserterapia na prevenção e tratamento das lesões de mucosite oral em pacientes submetidos à radioterapia de cabeça e pescoço: série de casos

Abstract

The onset of oral mucositis, an acute and painful inflammation, in patients undergoing head and neck radiotherapy. Low power laser has been studied and used as one of the ways to prevent and treat these injuries by healing and reducing painful symptoms. The aim of this study is to report four clinical cases of patients undergoing head and neck radiotherapy due to different types of neoplasms, and to address the effects of laser therapy in the treatment and prevention of oral mucositis. The treatment consisted of oral hygiene guidelines and laser therapy sessions. The laser therapy protocol used followed the following parameters: 78 points distributed through the oral mucosa; wavelength 660 nm; Energy of 0.3J, time 3 seconds per point and Energy Density = 10 J / cm2. After laser therapy sessions there was a significant improvement in the clinical condition of patients with wound healing and reduction of pain symptoms.
