Oral mucositis remains a limiting factor in in head and neck squamous cell carcinomas
patients treated with chemoradiation leading to pain, dysphagia, and weight loss. Low-level
laser therapy emerges as a promising, preventive therapy of chemoradiation-induced OM. This
study was designed to assess the efficacy of Low Level Laser Therapy (LLLT) in reducing the
incidence and/or severity of oral mucositis.
