PROBLEM TO BE SOLVED: To provide a dental two composition type polymerizable composition which can be used for multi-purposes, such as final prostheses for repairing denture bases or artificial teeth, for tooth crowns, tentative prostheses used until completed, excellent in color tones, a polishing property, discoloration during and after cured, mechanical characteristics, and the like, in good operability in states little containing air bubbles. SOLUTION: This dental polymerizable composition is characterized by comprising a composition I and a composition II, wherein the composition I comprises a polymerizable monomer (a) and a reducing agent (c) capable of decomposing a radical-producing agent (b), and the composition II comprises (meth)acrylate-based polymer particles (de) consisting mainly of a component (d) having a particle size distribution of 10 to 400μm, a median diameter in a range of 70 to 120μm, and a number-average mol.wt. (Mn) in a range of 50,000 to 250,000 and a component (e) having the same particle size distribution and the same median diameter as the those and a number-average mol.wt. (Mn) in a range of 300,000 to 700,000, and the radical-producing agent (b), and wherein the dental polymerizable composition can be cured, when the composition I is mixed with the composition II.
