Aims: The present study was done to assess the effect of three alcohol-free mouthwashes on radiation-induced oral mucositis in patients with head and neck malignancies. Materials and Methods: Eighty patients with head and neck malignancies, scheduled to undergo curative radiotherapy, were randomly assigned to receive one of the three alcohol-free test mouthwashes (0.12% chlorhexidine, 1% povidone-iodine, or salt/soda) or a control. The patients were instructed to rinse with 10 ml of the mouthwash, twice a day, for a period of 6 weeks. Mucositis was assessed at baseline and at weekly intervals during radiation therapy, using the World Health Organization criteria for grading of mucositis. The baseline demography of the four groups was matched for age, sex, stage of cancer, and whether the patient had cancer of oral or extraoral regions. A post hoc test for repeated measures was used to find the difference of mean mucositis scores between the groups at various week intervals. Results: Among the 76 patients who completed the study, patients in the povidone-iodine group had significantly lower mucositis scores when compared to the control group from the first week of radiotherapy. Their scores were also significantly lower when compared to the salt/soda and chlorhexidine groups from the fourth and fifth week, respectively, after radiotherapy. Conclusions: This study demonstrates that use of alcohol-free povidone-iodine mouthwash can reduce the severity and delay the onset of oral mucositis due to antineoplastic radiotherapy.
