Abstract Title:
Polyphenol-Rich Cranberry Extracts Modulate Virulence ofBiofilms Implicated in the Pathogenesis of Early Childhood Caries.
Abstract:
The purpose of this study was to investigate the effects of polyphenol-rich cranberry extracts on dual-speciesbiofilms implicated in contributing to the severity of early childhood caries.biofilms were grown on saliva-coated hydroxyapatite discs (s-HA) mounted on the high-throughput Amsterdam Active Attachment model. The s-HA discs were treated with the cranberry extracts/vehicle control for five minutes just before biofilm growth and subsequently, for similar exposure times, after 12 hours and 24 hours of biofilm growth. The treated 24-hour-old biofilms were then assessed for acidogenicity, metabolic activity, exopolysaccharide (EPS)/microbial biovolumes, structural organization, and colony forming unit (CFU) counts.Treatment with 500 to 1,000μg/mL of the cranberry extracts produced significant reductions in acidogenicity and metabolic activity (P
