Abstract: An adhesive composition for dental use exhibiting acidic property, including a mixture of a polymerizable monomer component (A) containing a phosphoric acid-type polymerizable monomer having an acidic group derived from phosphoric acid, and a multivalent metal ion-releasing component (B), wherein the multivalent metal ion-releasing component (B) is capable of releasing at least earth metal ions, and in the composition, earth metal ions stemming from the component (B) are present together with the phosphoric acid-type polymerizable monomer in such an amount that a total valency ratio (RE) defined by the following formula (1) is in a range of 0.2 to 3.0. The adhesive composition is capable of strongly adhering and fixing a composite resin or a prosthetic material to a tooth for extended periods of time maintaining stability.

Abstract: An adhesive composition comprising (A) a polymerizable monomer component containing not less than 5% by mass of an acidic group-containing polymerizable monomer, (B) a polyvalent metal ion-eluting filler, (C) a volatile organic solvent, and (D) water, wherein the polyvalent metal ion-eluting filler (B) is blended in such an amount that the amount of the polyvalent metal ions eluted out from the filler becomes 1.0 to 7.0 meq per gram of the polymerizable monomer component (A), the volatile organic solvent (C) is blended in an amount in a range of 30 to 150 parts by mass per 100 parts by mass of the polymerizable monomer component (A) and so as to satisfy 20·X parts by mass or more (X is a number representing the amount of elution of the polyvalent metal ions), and the water (D) is blended in an amount of 3 to 30 parts by mass per 100 parts by mass of the polymerizable monomer component (A).
