Effectiveness of mouthrinses in prevention and treatment of radiation induced mucositis: A systematic review.

Abstract

Mucositis is a frequent, severe consequence of radiation therapy among patients undergoing radiotherapy for the head-and-neck cancer, often requiring hospitalization and even breaks or discontinuity in treatment. Mouth rinsing with various agents has demonstrated effectiveness in the prevention and treatment of radiation-induced mucositis (OM), but evidence for the same is lacking. This systematic review is therefore conducted with the aim of assessing the evidence for the effectiveness of mouthrinses in prevention and treatment of OM. Joanna Briggs Institute guidelines were followed to conduct this review. Six databases were searched and a total of 25 randomized clinical trials published over a period of the past 31 years were included for qualitative synthesis. Analysis of 25 studies revealed that 1299 participants, aged 46-69 years were assigned to the test groups and control groups. A total of 16 different formulations were studied among patients over a duration of 6 days to 1 year in varying dosages. The overall preventive fraction ranged from 1.9% to 77.8% for a reduction in clinical grades of mucositis, 7.6%-83.3% for a reduction in pain and 20%-50% for a reduction in bacterial counts. Adverse effects such as mouth burning, altered taste, sore throat, have been reported, especially with chlorhexidine and benzydamine hydrochloride. Evidence for the included studies is IC and ID. Studies using herbal based products and tissue regenerating agents revealed comparatively better effectiveness with lesser side effects. However, the number of studies to support such a claim is very limited.
