MDPB is a polymerizable bactericide, and the
antibacterial component in the molecule is
immobilized after the resinous materials incorporat-
ing MDPB are cured (Fig. 3) 1,2,7)
. The component
immobilized as a pendant does not leach out from
resin matrix as they are connected by covalent
bond1,8)
. Therefore, incorporation of MDPB has an
advantage that physical properties of the restorative
materials are kept stable for a long period under wet
circumstances1,9)
