Low Level Laser Therapy Contributes to the Prevention of Mucositis and Immunity Against Sars-CoV-2

Juliano Abreu Pacheco

Abstract
Patients who are undergoing chemotherapy and radiotherapy treatments for head and neck are susceptible to developing Oral Mucositis (OM) in the oropharyngeal region. OM, if not properly treated, directly influences nutritional function and reduces immune defense, facilitating the spread of opportunistic infections and Sars-Cov-2 due to the presence of angiotensinconverting enzyme 2 (ECA2) present in the salivary glands. Low Level Laser Therapy (LLLT) appears as a treatment option, which prevents the manifestation of OM and promotes homeostasis in the defense cells and respiratory system.
