Although these isozymes have similar active sites, the patterns of exposed amino acids on their surfaces are different. Herein, we report the synthesis and molecular interactions of two watersoluble, fluorescentpolymers which demonstrate selective interactions with MMP-9 compared to MMP-7 and -10.
[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
(1)
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.

s optionally selected or all of the Z
q
s represent organic groups having a substituent which is an organic group other than a polymerizable group and a phosphonic acid group;
p is an integer from 1 to 10;
q is an integer from 1 to p;
when p is 1,
q is 1;
X

represents an organic group having one or more of substituents which are organic groups other than an acidic group and a polymerizable group, or a salt thereof. The adhesive composition or the salt thereof according to the present invention improve a shelf life and adhesion properties of an adhesive composition comprising essentially a (meth)acrylate monomer having intramolecularly an acidic group and water in dental treatment.
The present invention provides a dental adhesive composition that, even after photocuring with a high-output LED irradiator, shows high bond strength not only for dentin untreated by phosphoric acid etching but also for dentin treated by phosphoric acid etching. The present invention relates to a dental adhesive composition comprising a phosphoric acid group-containing polymerizable monomer (A), the phosphoric acid group-containing polymerizable monomer (A) comprising: a dihydrogen phosphate monoester group-containing polymerizable monomer (A-1) represented by general formula (1); a hydrogen phosphate diester group-containing polymerizable monomer (A-2) represented by general formula (2); and a phosphoric acid tetraester group-containing polymerizable monomer (A-3) represented by general formula (3).
