<P>PROBLEM TO BE SOLVED: To provide an adhesive composition for dentine, having high adhesive strength to dentine and also high storage stability, as a water-free adhesive material for dentine obtained by compounding an acid group-containing polymerizable monomer and silica together. <P>SOLUTION: The adhesive material for dentine comprises: (A) a polymerizable monomer component including at least an acid group-bearing polymerizable monomer as a part thereof: and (B) silica-based particles; wherein the silica-based particles have a specific surface area of 50-500 m<SP POS="POST">2</SP>/g and contain silanol groups at 3.5 counts/nm<SP POS="POST">2</SP>on the surface, preferably consist of fumed silica, and contain no water as well. <P>COPYRIGHT: (C)2013,JPO&INPIT |
