What this trial studies

This clinical trial evaluates the effectiveness of a copaíba-based mouthwash in preventing and treating oral mucositis in patients undergoing radiotherapy for oral cavity tumors. It is a double-blind, randomized phase II study where participants are assigned to either the copaíba mouthwash group or a placebo group, using the mouthwash four times a day. Patients will be monitored daily by a dental surgeon for symptoms of oral mucositis, pain, and dysphagia, and will also receive daily laser therapy sessions. The study aims to provide an alternative treatment method for oral mucositis, which is a common and painful side effect of radiotherapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with malignant neoplasms in the oral cavity or oropharynx who are scheduled to receive radiotherapy.

Not a fit: Patients currently receiving other treatments for oral mucositis or those whose radiotherapy does not include the oral cavity may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the incidence and severity of oral mucositis, improving the quality of life for patients undergoing radiotherapy.

How similar studies have performed: Previous studies have shown promising results with copaíba in similar contexts, but this specific approach is novel in the setting of oral mucositis prevention during radiotherapy.
