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)
0t2t13.0(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).
