Effects of polyols on periodontopathic biofilm development

Our previous study showed that sugar alcohols(polyols) such as erythritol inhibited Streptococcus gordonii-Porphyromonas gingivalisbiofilm formation and erythritol was the most effective reagent to reduce P. gingivalisas compared with other tested polyols. To examine the inhibitory effects of erythritol, we analyzed the metabolomic profiles of erythritol-treated P. gingivalis and S. gordonii cells. These results suggest that erythritol has inhibitory effects on dual species biofilm development via several pathways, including suppression of growth resulting from DNA and RNA depletion and alteration of central carbon metabolism.
