Oral mucositis is a frequent and painful side effect of radio- and chemotherapy, especially in patients with head and neck cancer. It can cause severe discomfort, difficulty eating and swallowing, infections, and interruptions of cancer treatment. This study evaluates the effectiveness of ozone therapy, delivered both professionally in the dental clinic and at home with ozone-based toothpaste, mouthrinse, and gel, in reducing symptoms of oral mucositis and stomatitis. Fifty-eight adult cancer patients with oral mucositis of at least WHO grade 1 are included. Professional ozone therapy sessions are performed in-office, combined with daily home use of ozonated products. The main goal is to determine how many days are needed for lesions to heal (WHO ≤ 1). A secondary goal is to measure pain reduction using a visual analogue scale (VAS). This research aims to provide evidence for a supportive care protocol that may improve quality of life, reduce treatment complications, and support cancer patients during therapy.
