Low-energy laser in the management of radiation-induced oral mucositis: report of two cases

Abstract

Oral mucositis is a common, dose-limiting, and potentially serious complication of cancer therapy. Severe mucositis can lead to modifications of treatment planning and even suspension of therapy, with a negative impact on local tumor control and patient survival, increasing the risk of local and systemic infections. The lesions generally develop in non-keratinized mucosa, which is most vulnerable to this complication. Symptoms can range from a burning sensation to severe pain that impairs nutrient and fluid intake. Low-energy laser has been proposed for treatment of mucositis, with good clinical and functional results, accelerating the healing process and decreasing the pain. The aim of this article, illustrated by two clinical cases at the Pernambuco Cancer Hospital in Recife, Brazil, was to report on the efficacy of low-energy laser in the management of radiation-induced oral mucositis.
