Roopashri, G., Jayanthi, K., & Guruprasad, R. (2011). Efficacy of benzydamine hydrochloride, chlorhexidine, and povidone iodine in the treatment of oral mucositis among patients undergoing radiotherapy in head and neck malignancies: A drug trail. Contemporary Clinical Dentistry, 2, 8–12.
To manage oral mucositis induced by radiotherapy and to reduce pain by using benzydamine hydrochloride, chlorhexidine, and povidone iodine
Selected patients were divided into study and control groups. The study groups were further subdivided into group 1, group 2, and group 3. Each study group consisted of 25 patients, and the control group also consisted of 25 patients; the three study groups and the control group were given benzydamine hydrochloride, chlorhexidine, povidone iodine, and distilled water, respectively. These rinses were given after two weeks of radiation therapy (RT) at the onset of oral mucositis.
Patients in the study groups as well as the control group were instructed to rinse the oral cavity with 15 ml of their respective rinses for at least 30 seconds, 4 times a day at six-hour intervals. The mouth-rinsing regimen was performed under professional supervision. The samples of mouth rinses were given to the patients without dilution for one week use, one at a time, for convenience. Patients also were given measuring cups to measure the quantity of oral rinses. All patients were examined at the end of every week during the RT for about a six-week period.
The study was conducted at the Radiotherapy Department of Kidwai Memorial Institute of Oncology in Bangalore, Karanataka, India.
Patients were undergoing the active treatment phase of care.
The study did not involve blinding.
This study was oorly designed, and the report was confusing and difficult to understand.
Several studies have pointed in the direction that benzydamine hydrochloride is effective in the management of oral mucositis. Further well-designed, randomized placebo controlled studies are needed for verification.
