Influence of Amalgam, Alloy, and Hg on the In Vitro Growth of Streptococcus mutans: III. Effect of Specimen Age and Composition

Abstract
In vitro growth inhibition of Streptococcus mutans is lost with sample age at different rates for amalgams Prepared from a spherical, fine cut, and dispersion alloy. Varying the Hg composition from 48 to 52% has little effect on growth inhibition.
