A dental adhesive material kit may have desirable adhesive properties for tooth structure, and, while ensuring appropriate strength, may allow easy removal of excess cement in a semi-cured state created by temporarily applying light to excess portions of cement with a photoirradiator. Such a dental adhesive material kit may include a dental aqueous adhesive composition (A) and a dental curable composition (B), satisfying the inequality (I)0≤2−1≤3.0  (I),wherein t1 (min) is a contactual polymerization start time of the dental aqueous adhesive composition (A) and the dental curable composition (B), and t2 (min) is a polymerization start time of the dental curable composition (B).

Dental adhesive material kit

The present invention provides a dental adhesive material kit that exhibits high adhesive property to tooth structure and dental prosthesis through photopolymerization while maintaining good ease of handling with the paste properties that undergo little change during long storage. The present invention relates to a dental adhesive material kit comprising: an aqueous adhesive dental composition (X) comprising a radical polymerizable monomer (a) containing an acidic group, a polymerization accelerator (b), water (c), and a radical polymerizable monomer (d) containing no acidic group; and a curable dental composition (Y) comprising a hydrophilic radical polymerizable monomer (d-1) containing no acidic group, a hydrophobic radical polymerizable monomer (d-2) containing no acidic group, a chemical polymerization initiator (e), a photopolymerization initiator (f), and a filler (g), the filler (g) being a filler treated with a surface treatment agent, and having an average particle diameter of 0.01 to 50.0 &#x3bc;m, the surface treatment agent comprising a silane coupling agent (A) represented by general formula [1], and an organosilazane (B) represented by general formula [2].
