Comparative evaluation of curcumin and antioxidants in the management of oral submucous fibrosis.

Abstract

The present study aims to evaluate the efficacy and safety of curcumin in both topical and systemic forms for management of oral submucous fibrosis in comparison with the antioxidants. In this randomized parallel-group single-center trial, 119 patients were enrolled. Group I received antioxidants, group II received curcumin in systemic form and group III received curcumin in both systemic and topical forms. The primary outcomes assessed were interincisal mouth opening and burning sensation using a visual analog scale. The secondary outcomes were tongue protrusion and adverse reactions. The response to treatment was analyzed using ANOVA and Fisher's exact test. Significant improvement in mouth opening, burning sensation and tongue protrusion was observed in all groups at 12weeks. Mean improvement in burning sensation did not show statistical difference across the groups. A significant difference between groups II and III for improvement in mouth opening and groups I and III for improvement in tongue protrusion was noted. When administrated in both systemic and topical forms together, curcumin showed better results in the management of oral submucous fibrosis as compared with the systemic form alone or antioxidants. Curcumin has the potential to emerge as an effective alternative to conventionally prescribed medications.
