Background and Objective: The purpose of this study was to investigate the effects of cranberry polyphenol fraction on biofilm formation and activities of Arg‐gingipain and Lys‐gingipain in Porphyromonas gingivalis. Material and Methods: The polyphenol fraction was prepared by using a glass column packed with Amberlite XAD 7HP and 70% aqueous ethanol as an elution solvent. Results: Synergistic biofilm formation by P. gingivalis and Fusobacterium nucleatum was significantly inhibited by the polyphenol fraction at a concentration of 250 µg/mL compared with untreated controls ( p < 0.01). Arg‐gingipain and Lys‐gingipain activities in P. gingivalis ATCC 33277 and FDC 381 were inhibited significantly at a polyphenol fraction concentration of ≥ 1 µg/mL ( p < 0.05). Conclusion: These findings indicate that the polyphenol fraction inhibits biofilm formation and the Arg‐gingipain and Lys‐gingipain activities of P. gingivalis .
