Ozone Therapy With Biomimetic Oral Care for Cancer-Related Oral Mucositis

Oral mucositis is a frequent and often debilitating complication of radiotherapy and chemotherapy, particularly in patients treated for head and neck cancers. It is characterized by inflammation and ulceration of the oral mucosa, leading to pain, difficulty swallowing, taste disturbances, dry mouth, and impairment of daily activities. In more severe cases, oral mucositis may require modification or temporary interruption of cancer treatment. This randomized controlled clinical trial is designed to assess the clinical effectiveness of gas ozone therapy in patients with radio- and chemotherapy-induced oral mucositis. In addition, the study will evaluate whether combining ozone therapy with a structured biomimetic oral care regimen, including toothpaste and mouthwash, provides additional clinical benefit compared with ozone therapy alone. Eligible participants will be randomly assigned to one of two parallel groups. The control group will receive gas ozone therapy administered in an outpatient setting according to a standardized protocol. The experimental group will receive the same ozone therapy combined with a defined home oral care regimen. Each participant will be followed for 30 days. The primary outcome is the change in oral mucositis severity, assessed using the World Health Organization Oral Toxicity Scale. Secondary outcomes include oral pain intensity, salivary flow rates, perceived dry mouth, taste alterations, swallowing function, oral pH, overall oral health-related quality of life, and treatment tolerability. The findings of this study are expected to clarify the role of ozone-based supportive care strategies in the management of cancer therapy-related oral mucositis and to contribute to the development of standardized non-pharmacological treatment protocols.

Prevention of Oral Mucositis in Head and Neck Cancer.

Oral Mucositis (OM) consists in the painful inflammation and ulceration of the mucous membranes lining the digestive tract, lasting between 7 and 98 days; and starts as an acute inflammation of oral mucosa, tongue, and pharynx after RT exposure. Gel X spray is a product based on zinc gluconate. It could be helpful to achieve the prevention of Oral Mucositis and, in case of OM manifestation, the reduction of oral pain symptoms and to accelerate the healing process of oral mucositis ulcerations. The aim of this study is to demonstrate the efficacy of the treatment with Gel X to reduce the incidence of oral mucositis, in comparison with Sodium Bicarbonate.

Amimestrocel Injection for Preventing Severe Oral Mucositis in HSCT Patients

This study aims to see if a single intravenous infusion of a cell therapy called Amimestrocel injection can help prevent severe mouth sores (oral mucositis) in patients receiving a stem cell transplant. Patients getting a stem cell transplant often receive strong chemotherapy (with radiation and/or a drug called melphalan) that can cause painful mouth and gut sores, making eating difficult and increasing infection risk. Amimestrocel injection is made from human umbilical cord cells that may help reduce inflammation and promote healing. About 22 adult patients scheduled for this type of transplant at one hospital in China will receive the infusion 1-2 days before their stem cell transplant. Researchers will closely check for mouth sores, pain, and side effects for the first 28 days, and continue safety monitoring for 100 days. The main goal is to see if the treatment lowers the rate of severe (Grade 3-4) mouth sores. The study will also track pain levels, need for pain medication, diarrhea, time for blood counts to recover, and overall safety.

The goal of this study is to describe the effect of photobiomodulation (PBM) on the incidence and severity of oral mucositis in post-operative oral cancer patients receiving radiotherapy +/- chemotherapy. Participants will receive PBM treatment five times a week throughout the course of their radiotherapy. The main question it aims to answer is whether photobiomodulation reduces the incidence and severity of oral mucositis.

Photobiomodulation in the Prevention and Management of Oral Mucositis in Children

Oral mucositis (OM) is a frequent, debilitating complication in pediatric oncology that impairs quality of life, nutrition, hydration, and treatment adherence. This randomized, prospective, single blind trial in Mexico will evaluate photobiomodulation (PBM) versus a conventional bioadhesive gel for prevention and treatment of antineoplastic therapy-induced OM in children aged 4-17 with leukemia, lymphoma, or head and neck tumors. A total of 49 participants will be enrolled. The study has two components: (1) Treatment - parallel comparison of PBM versus bioadhesive gel for established OM; (2) Prevention - crossover design in which patients receive both interventions across successive chemotherapy cycles. PBM will be delivered with a 660 nm device, 40 mW, 10 J/cm². The primary outcome is OM grade by the WHO scale assessed on days 7, 11, 14, and 21. Expected results include reduced OM incidence, severity, duration, and pain with favorable safety and tolerability, supporting standardized PBM protocols in pediatric oncology in Mexico.

Oral Herpesviruses and Oral Mucositis in Patients Receiving Head and Neck Radiotherapy

Patients receiving radiotherapy for head and neck cancer often develop oral mucositis, a painful condition that causes redness and sores in the mouth. Oral mucositis can make it difficult to eat, drink, and speak, and may interfere with cancer treatment. Some viruses from the herpesvirus family, which commonly remain inactive in the body, may become active during cancer treatment and worsen mouth sores. However, the role of these viruses in oral mucositis is not fully understood. This study aims to understand whether herpesviruses present in the mouth are associated with the development and severity of oral mucositis in adults receiving radiotherapy for head and neck cancer. The study also evaluates whether taking an antiviral medication (valacyclovir) can reduce viral activity and improve mouth symptoms during treatment. Participants are randomly assigned to receive either valacyclovir or a placebo while undergoing radiotherapy. Samples from the mouth and saliva are collected at different time points before, during, and after radiotherapy to detect herpesviruses. Mouth sores are regularly examined, and pain levels are recorded throughout treatment. The results of this study may help clarify the role of herpesviruses in oral mucositis and support better strategies to prevent or manage this condition in patients receiving radiotherapy for head and neck cancer.

Efficacy of Orosol® in the Treatment of Chemo- and Radiation-induced Mucositis.

Oral mucositis is one of the most debilitating side effects of radiation therapy and various forms of chemotherapy, especially for head and neck cancers and hematopoietic stem cell transplants. It is a consequence of the cytostatic effects of anticancer treatments on rapidly renewing cells of the oral mucosa; An ulcer appears which will increase in size due to subsequent bacterial, fungal and / or viral growth, while the leakage of toxins through damaged capillaries causes irritation and a burning sensation. Proteolytic enzymes, known to destroy the extracellular matrix, inhibit cell regeneration and healing. Depending on the severity of the ulceration, infection and feeding possibilities, mucositis is scored between grade 0 (absent) and grade 4 (maximum) (according to the WHO (World Health Organization) classification or the NCI-CTCAE (National Cancer Institute-Common Terminology Criteria for Adverse Events), the latter degree most often requiring a modification of the anticancer treatment which may have an impact on the prognosis of the disease. Although, theoretically, mucositis is easy to treat because it only requires simple cleaning of the ulcers and stimulation of the growth of the underlying healthy cells to make up for the loss of substance, there are currently only limited symptomatic treatments available.

Comparison of Prophylactic Photobiomodulation Protocols in Chemoinduced Oral Mucositis in Oncology Patients

Childhood cancers represent less than 1% of the malignant diseases diagnosed worldwide. Treatment modalities for childhood malignancies will differ depending on the diagnosis. The main treatments may include chemotherapy (QT), radiation therapy (RT), and surgery. The toxicity caused by QT and RT generates adverse effects in the mouth, among them oral mucositis (MO). MO is damage that occurs to the oral mucosa and these lesions are extremely painful, uncomfortable, and cause great morbidity for patients. The main treatment of MO is intraoral photobiomodulation therapy (TBMI), this therapy has been widely used, reducing the severity and pain of MO in patients. The use of extraoral photobiomodulation therapy (TFBME) has been employed in some recent studies and has shown efficacy for reducing and improving the severity of OM. The present study aims to compare the effect of two protocols of photobiomodulation therapy (TFBM) using intraoral and extraoral low power laser in the prevention and treatment of OM in pediatric oncology patients receiving treatment with high dose metrotexate (MTX-HD) and its chemotherapy combinations. Initially, 34 pediatric and adolescent oncology patients receiving intravenous (IV) QT from risk protocols will be selected. Participants will be allocated into 2 groups: Group I: TFBMI (n=17) and Group II: TFBME (n=17). The study will be conducted by a dental surgeon who will perform the initial assessment and reassessments (blinded to the groups) and another who will apply the TFBM. Patients will be evaluated daily from day 1 (D1 - beginning of the chemotherapy cycle) until D10 or until healing of the lesions. The evaluation will consist of oral mucosa examination for grading of OM, pain assessment, quality of life, oral health, depressionand saliva evaluation of patients to assess. The analyses will be performed in the PASW 18.0 program, initially the evaluation of the data distribution will be performed by applying the Shapiro-Wilk and Kolmogorov-Smirnov tests. If, after applying these tests, the data show a normal distribution (p\>0.05), the t-test will be used. If the distribution is non-normal after the application of the tests (p\<0.05), the Wilcoxon test will be used. The p value will be set at 5%. Logistic regression will be used in adjusted models to estimate the probability of occurrence of OM.

Lactobacillus Rhamnosus GG Alleviates Oral Mucositis in Patients Undergoing Radiotherapy

Radiation therapy is a common treatment modality in the management of head and neck malignancies. However, head and neck tumors often have some adverse reactions when receiving radiation therapy, such as dry mouth, change of taste, oral mucositis, etc. Among them, the incidence of oral mucositis is more than 90%, and the incidence of oral mucositis of degree 3 or more than degree 3 is more than 50%. Severe oral mucositis seriously affects the quality of survival of patients. Lactobacillus rhamnosus GG (LGG) is a type of lactic acid bacterium, which is an important component of the microbiota in many parts of the human body. Lactobacillus rhamnosus GG (LGG) is a lactic acid bacterium found in the human body, extensively researched for its probiotic properties. It has been tested in clinical trials for preventing and treating oral mucosal reactions during intensified radiotherapy for head and neck squamous cell carcinoma. LGG adheres well to epithelial layers, produces a protective biofilm, and modulates immune responses. It shows promise in reducing radiation-induced oral mucositis and can be safely used in infant formula. Additionally, a daily dosage of 3×10\^9 CFU of LGG has been effective in treating irritable bowel syndrome without adverse effects
