This is a prospective, single blind, two arm, randomized, controlled trial to test the efficacy of an oral care protocol to treat oral mucositis (OM) in patients receiving radiation (RT) or chemoradiation (chemoRT) for head and neck cancer. This trial will also measure salivary proinflammatory cytokines, and evaluate other clinical effects of the intervention during cancer therapy. In addition, oral mucosal swabs will be collected for the future characterization of changes in the microbiome associated with OM severity. Patients will be randomized in a 1:1 ratio to two different oral care protocols within 4 strata defined by type of RT (Proton beam therapy (Protons)) vs intensity-modulated radiation therapy (IMRT) and cancer treatment (RT versus chemoRT). Eligible subjects will be assigned to receive either the Oral Mucosal Deterging and Dental Prophylaxis protocol (OMDP) or a Standard of Care Oral Hygiene protocol (SOC-OH). Prior to randomization, all enrolled subjects will receive a baseline dental prophylaxis and fluoride varnish application prior to start of RT or chemoRT to ensure that all subjects enter the study with comparable oral health. Subjects assigned to OMDP will receive the OMDP Protocol (Oral Mucosal Deterging and Dental Prophylaxis) at weekly intervention visits. Subjects randomized to the SOC-OH will receive oral health instructions following the American Dental Association Guidelines1 and will have their teeth cleaned (brushed) during weekly intervention visits; no treatment to the oral mucosa will be provided to this group. At each bi-weekly study visit, study assessments will include the collection of saliva and oral mucosal swabs, an oral exam and OM assessment, and the completion of questionnaires. During the course of the study, subjects will attend one baseline visit, up to 9 intervention visits, and a follow-up visit approximately 3 months after completion of RT. Local supportive care, including normal saline rinses, topical anesthetics, mixed medication mouthwashes (e.g. Magic Mouthwash), feeding tubes, and pain management will be allowed according to each recruitment site's standard of care procedures.
