摘要： [Problems] To provide a one-package type tooth surface coating material that is capable of forming, on the surface of a tooth, a cured film having not only a very high strength of adhesion to the tooth surface but also excellent properties such as long-term adhesion, long-term durability, dentinal tubule occlusion and aesthetic appearance, and that has excellent storage stability and can be stored in the form of one package.
[Means for Solution] A one-package type tooth surface coating material comprising (A) a polymerizable monomer component containing not less than 5% by mass of an acidic group-containing polymerizable monomer; (B) polyvalent metal ions; (C) a volatile water-soluble organic solvent; (D) water; and (E) an effective amount of a photopolymerization initiator; the amount of the polyvalent metal ions (B) and the amount of the volatile water-soluble organic solvent (C) satisfying a specific relationship.

摘要： [Problems] To provide a liquid dental adhesive composition which contains a phosphoric acid-type compound having a hydrogenphosphoric diester group as an acidic group-containing polymerizable monomer and, further, contains polyvalent metal ions, effectively preventing not only the gelation but also the formation of precipitates (cloudiness) during the storage.
[Means for Solution] A dental adhesive composition which is acidic and contains an acidic group-containing polymerizable monomer (A), polyvalent metal ions (B), water (C), a water-soluble organic solvent (D) and fluoride ions (E), wherein at least 35% by mole of the acidic group-containing polymerizable monomer (A) is a phosphoric acid-type compound having a hydrogenphosphoric diester group, and the contents of the fluoride ions (E) and the polyvalent metal ions (B) are so set that a valence number ratio (R F ) defined by the following formula (1): R F = V F / TV P
wherein V F is a valence number of the fluoride ions (E) contained in the composition , and TV P is a total valence number of the polyvalent metal ions (B) contained in the composition,
satisfies a range of 0.2 to 2.0.
