Inhibition of Adherence of Streptococcus mutans to Glass Surfaces

Abstract
Maltose and low-molecular weight dextran inhibited the adherence of Streptococcus mutans to the smooth glass surface of scintillation vials. Inhibition of adherence paralleled inhibition of insoluble glucan synthesis, confirming a role of these polymers in the adherence mechanism. At maximum inhibition of adherence, there was a 60–70% decrease of S. mutans cells sticking to smooth glass surfaces. These results suggest that the incorporation of maltose or low-molecular weight dextran in food stuffs should be investigated as a measure to reduce caries.
