Comparação do uso de Solidago chilensis (Arnica) e laserterapia de baixa intensidade para prevenção de mucosite oral em pacientes submetidos radioterapia de cabeça e pescoço e/ou à quimioterapia de alta toxicidade

The oral mucositis is an adverse event of radiotherapy and/or high toxicity chemotherapy. The Solidago chilensis (Arnica) has been used for its antiseptic, analgesic, healing and anti-inflammatory properties. Objective: The purpose of this study was to evaluate the uses of Arnica for oral mucositis prevention in patients submitted to radiotherapy for head and neck tumors treatment and/or high toxicity chemotherapy. Methodology: The determination of the cytotoxicity index of the aqueous extract was determined in vitro. The oral mucosa was evaluated in days 0, 10 and 14 of patients in the groups: treated with lasertherapy (L, n=18), treated with Arnica (A, n=24) and, treated with lasertherapy associated with Arnica (LA, n=4). It was considered significant p
