  • Title: [Effects of sodium doecyl sulfate on the artificial dental plaque in chemostat].
    Author: Wei G, Qiao W, Bian Z.
    Journal: Zhonghua Kou Qiang Yi Xue Za Zhi; 1997 Nov; 32(6):347-9. PubMed ID: 11189307.
    Abstract:
    Sodium doecyl sulfate (SDS) is widely used as a detergent in dentifrices. It has been shown to interfere with the protein adsorption to hydroxyapatite (HA), and inhibit acquired pellicle formation. The aim of the present study was to examine the effects of SDS on the artificial dental plaque in chemostat. The amount of the 3H-labelled bacteria adhered on the enamel fragment surface was determined with scintillometer. The artificial dental plaque was observed under the scanning electron microscope. The results showed that enamel fragments treated with SDS adsorbed less bacteria than untreated ones, and had no plague formed. It suggested that SDS can inhibit the bacterial adherence on enamel surface and thus reduce dental plaque formation.
