ABSTRACT

Objective: In this study, patients undergoing neck and head radiotherapy (RT) with or with no chemotherapy were contrasted to the low-level laser therapy (LLLT) efficacy against benzydamine hydrochloride in treating and preventing oral mucositis (OM) (CHT). Material and Methods: This study included 90 individuals with neck and head cancer who were undergoing radiotherapy (RT) individually or in mixture with chemotherapy (CHT), varying in age from 18 to 80 years. Three equal groups were randomly formulated: Group, I patients were using oral care only, Group II patients were using benzydamine hydrochloride mouth rinse, and Group III patients were medicated by using low-level laser therapy. The National Institute of Cancer-Common Toxicity Criteria (NIC-CTC) and the World Health Organization (WHO) were used to rate the severity of OM, and the pain was validated utilizing a visual analog scale (VAS). The salivary level of tumor necrotic factor-α (TNF- α) was assayed. Results: As per WHO and NIC, the grade of oral mucositis at the end of cancer treatment was less in the LLLT group than in the other two groups. The alteration in TNF- α level was not significant. The laser group is more liable to have less salivary levels of the pro-inflammatory cytokines TNF- α . Conclusion: The incidence of oral mucositis severity has seemed to be reduced due to the prophylactic use of benzydamine hydrochloride and laser therapy protocols. However, laser therapy was more efficient in controlling the shape and progression of OM (AU)


Objetivo: Neste estudo, pacientes submetidos à radioterapia (RT) da cabeça e pescoço com ou sem quimioterapia foram avaliados quanto à eficácia da terapia com laser de baixa potência (LLLT) versus o cloridrato de benzidamina no tratamento e prevenção da mucosite oral (MO) (CHT). Material e Métodos: Este estudo incluiu 90 indivíduos com câncer de cabeça e pescoço submetidos à radioterapia (RT) individualmente ou em combinação com quimioterapia (QT), com idade variando de 18 a 80 anos. Três grupos iguais foram aleatoriamente formulados: os pacientes do Grupo I usaram apenas higiene bucal, os pacientes do Grupo II usaram bochechos com cloridrato de benzidamina e os pacientes do Grupo III foram medicados com terapia a laser de baixa intensidade. Foram utilizados os critérios do National Institute of Cancer-Common Toxicity Criteria (NIC-CTC) e da Organização Mundial da Saúde (OMS) para classificar a gravidade da OM, e a dor foi validada utilizando uma escala visual analógica (VAS). O nível salivar de fator necrótico tumoral-α (TNF-α) foi ensaiado. Resultados: De acordo com a OMS e NIC, o grau de mucosite oral ao final do tratamento do câncer foi menor no grupo LLLT do que nos outros dois grupos. A alteração no nível de TNF-α não foi significativa. O grupo com tratamento a laser apresentou menores níveis de citocinas pró-inflamatórias TNF-α na saliva. Conclusão: A gravidade da mucosite oral parece ser reduzida devido ao uso profilático de cloridrato de benzidamina e protocolos de laserterapia. No entanto, a laserterapia foi mais eficiente em controlar a forma e a progressão da MO. (AU)
