A dental powder/liquid material-containing preparation accommodation bag, which suppresses entrainment of air in mixing a powder material and a liquid material for dispensing, is provided. A powder materialis accommodated in a powder material accommodation chamberof a bag body, while a liquid materialdissolving the powder materialand changing into a pasty form, in cooperation with the powder materialis accommodated in a liquid material accommodation chamberpartitioned from the powder material accommodation chamberby a weakened section. The weakened sectionis ruptured by applying a pressing force to the bag body. As a result, the powder material accommodation chamberand the liquid material accommodation chambercommunicate, to feed the liquid material accommodated in the liquid material accommodation chamberinto the powder material accommodation chamber. Then, the powder materialand the liquid materialchanging into the pasty form are pressed within the powder material accommodation chamberfrom the surfaces of the bag bodyfor dispensing.

A powder-liquid dental curable material kit composed of (A) a liquid material and (B) a powder material, wherein the liquid material (A) contains (a1) a radically polymerizable (meth)acrylic monomer, (a2) an organic halogen compound and (a3) a radical chain transfer agent; the powder material (B) contains (b1) non-crosslinked resin particles, (b2) a pyrimidinetrione compound and (b3) an organic metal compound; and (Z) a peroxide is blended in at least one of the liquid material (A) and the powder material (B). This curable material kit is capable of reducing the heat generation during the curing of a curable material which is a mixture of the liquid material (A) and the powder material (B) and is not susceptible to the excessive prolongation of the curing time even when the curable material is cured by a brush-on technique, thereby ensuring an appropriate curing time for both of a brush-on technique and a kneading technique.
