Abstract

The objective of this study was to determine the oral wound healing effects of acai berry water extracts (ABWE) in rat oral mucosa. To estimate the anti-oxidative effects of ABWE, the contents of phenolic compounds, and DPPH (1,1-diphenyl-2-picryl hydrazyl) and ABTS (2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)) abilities were evaluated. Wound healing effects of ABWE were tested following 6-day exposure after induction of wound by applying 50% acetic acid to oral mucosa of Sprague-Dawley rats. Macroscopic and histopathological analyses were performed to determine wound healing effects of ABWE. Sodium fusidate (20 mg/g) was used as positive control. ABWE showed significantly high antioxidant effects in all assays, although its potency was weaker than the positive control. From day 3 after treatment, wound healing effects of ABWE were observed in oral mucosa. These wound healing effects were also consistent with histopathological evaluation results. Taken together, these results indicate that ABWE might have potential as an oral wound healing agent in the future.
