In Vitro Inhibition of Pathogens by Polyols: Optical Density-Based Screening and Implications for the Oral–Systemic Axis

. Collectively, these results identify polyol- and taxon-specific growth phenotypes that can inform the formulation of swallow-safe oral hygiene products and motivate follow-up work in polymicrobial biofilm models and clinical studies targeting oral inflammation and downstream systemic risk.
