Abstract
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.
