Abstract
Background
Recurrent aphthous stomatitis (RAS) is the most common ulcerative lesion of the oral mucosa. The management of RAS is quite challenging with no definitive cure.
Objective
The present systematic review aimed to summarize the available evidence regarding the efficacy of curcumin in the management of RAS.
Methods
PubMed, Scopus and Web of Science databases were searched in June 2020 for all relevant studies. Clinical trials that assessed the efficacy of curcumin for the management of RAS were included. The primary outcomes were pain and/or clinical improvement.
Results
Eight studies involving 439 subjects were included. The efficacy of curcumin was compared with 1% triamcinolone in four studies, glycerin vehicle in one study, placebo in one study, and honey in one study. Overall, the included studies reported a good efficacy of curcumin in reducing pain and ulcers size in patients with RAS. Four studies found curcumin as effective as triamcinolone in relieving signs and symptoms of RAS. Three studies reported superior results with curcumin as compared with control groups.
Conclusion
The limited available evidence suggests that curcumin have potential benefits in alleviating pain and accelerating healing in patients with RAS. Further well-designed clinical trials with standardized curcumin formulations are highly recommended.
