The present invention provides a one-part dental adhesive composition that exhibits excellent adhesive property and bond durability to a tooth structure (particularly dentin) and has high stability to ambient light, in which respective components have been mixed uniformly. The present invention is a one-part dental adhesive composition including a polymerizable monomer (A) having an acidic group, a polymerizable monomer (B) having a fluorocarbon group represented by the general formula (1), water (C), and a polymerization initiator (D). A content of the polymerizable monomer (A) having an acidic group is 5.5 to 35 parts by weight in 100 parts by weight of the total amount of polymerizable monomers. (In the formula, Rdenotes a hydrogen atom or a methyl group, and Rf denotes a fluoroalkyl group having 1 to 20 carbon atoms.) 

One-part dental adhesive composition

The present invention provides a dental adhesive material kit having excellent bond durability. The present invention is represented by a dental adhesive material kit containing a dental aqueous adhesive composition (A) and a multi-part type dental nonaqueous curable composition (B). The dental aqueous adhesive composition (A) contains a polymerizable monomer (a) having an acidic group, an aliphatic polymerizable monomer (b) having no acidic group, water (c), and an amine-based reducing agent (d1) containing no sulfur atom. The multi-part type dental nonaqueous curable composition (B) contains an aliphatic polymerizable monomer (b) having no acidic group, an aromatic polymerizable monomer (e) having no acidic group, a powdery water-soluble reducing compound (f) containing a sulfur atom, an organic peroxide (g), and an amine-based reducing agent (d2) containing no sulfur atom.

Dental adhesive material kit

A novel compound (I) represented by the following formula (1) is provided which is suitable for a dental composition and has a polymerizable group, a carboxyl group and a phosphoric acid group. A method for producing a polymerizable amide is provided, which method can make a condensation reaction of a carboxylic acid with an amine to proceed easily and is excellent in safety: wherein R, Rand Reach independently are a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms which may have a substituent; (A) and (B) are each any constituent unit; m is an integer of from 1 to 3; n is an integer of from 1 to 3; Ris an organic group having 1 to 40 carbon atoms which may have a substituent; Ris a hydrocarbon group having 1 to 20 carbon atoms which may have a substituent, Rand Reach independently are a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms which may have a substituent, or a metal atom.
