<p><P>PROBLEM TO BE SOLVED: To provide a tooth surface pre-treating material composition which can solve such a problem that high adhesive strengths have not been obtained by conventional techniques, even when dental adhesives are applied to bleached tooth dentins. <P>SOLUTION: This tooth surface pre-treating material composition for adhesion after bleached, containing a reducing compound to recover the adhesive force of the tooth surface bleached with a tooth bleaching agent containing at least one compound selected from the group consisting of organic peroxides, compounds producing hydrogen peroxide in aqueous solutions, and titanium dioxide, is characterized in that the reducing compound is at least one compound selected from the group consisting of sulfinic acid compounds, inorganic sulfite compounds, amine-based compounds and ammine complexes. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
