Abstract
The adherence of a common dental plaque bacterium, Streptococcus sanguis, to various types of dental cements in vitro was investigated. Adherent bacteria were counted by using a fluorescent microscope.
The adherence of the cells was found to depend on the incubation time and pH of the incubation medium. Various types of cements differed in their qualities as a substrate for bacterial adhesion. Glass
ionomer, silicate and polycarboxylate cements showed a high degree of cell adhesion, EBA and resin cements were poor substrates for cell adherence. Particular components of cements seem to have different
ability for the adherence of the bacterial cells.
