The purpose of this study was to evaluate the rate of adherence of bacteria on various denture relining materials and to find out the effects of chitosan, when it was added to denture relining materials. Denture relining materials such as Tokuso rebase normal $set^{(R)}$, Mild $rebaron^{(R)}$, $Kooliner^{TM}$, and New $truliner^{TM}$ were used in this study. The adherence of Streptococcus mutans was studied on the surfaces in the denture relining materials with chitosan and in those without chitosan. When chitosan was added to M17 broth and MRS broth, the viable cell count of Streptococcus mutans was reduced. The viable cell count of Streptococcus mutans on the specimens decreased in the following order : Mild rebaron, Tokuso rebase normal set, and Newtruliner and Kooliner. The deture relining materials with chitosan showed a lower rate of adherence of Streptococcus mutans than those without chitosan.
