  • Title: In vitro testing of xylitol as an anticariogenic agent.
    Author: Sahni PS, Gillespie MJ, Botto RW, Otsuka AS.
    Journal: Gen Dent; 2002; 50(4):340-3. PubMed ID: 12640850.
    Abstract:
    A number of studies involving xylitol chewing gum have demonstrated that xylitol is both noncariogenic and anticariogenic. The ability of xylitol to act as an anticariogenic agent most likely is due to its ability to be transported into caries-causing oral bacteria and inhibiting fermentation either by depleting the cell of high-energy phosphate or by poisoning the glycolytic system. In vitro tests were conducted to determine the concentration of xylitol required to inhibit the growth of three strains of oral streptococcus (S. mutans, S. salivarius, and S. sanguis). All three strains were inhibited significantly at xylitol concentrations of 12.5% and higher; however, only S. mutans was inhibited significantly at a xylitol concentration of 1.56%.
