Abstract: PURPOSE: A composition of dental self-curing resin cements is provided, which composition is ointment-ointment system of which usage is convenient, and has improved fluidity, low polymerization contraction rate, low water absorption, low water solubility and low viscosity, so that the amount of an added diluting agent can be reduced and a large amount of inorganic filler can be mixed. CONSTITUTION: The composition of dental self-curing resin cements comprises a paste composition A comprising 1 to 25 wt.% of prepolymer mixture, 1 to 20 wt.% of diluting agent, 0.1 to 15 wt.% of adhesive monomer, 0.1 to 3 wt.% of polymerization initiator, 0.1 to 3 wt.% of polymerization inhibitor, 0.1 to 2 wt.% of photo-stabilizing agent, 0.1 to 2 wt.% of oxidation inhibitor, 0.005 to 1 wt.% of inorganic dye, and inorganic filler; and a paste composition B comprising 1 to 25 wt.% of prepolymer, 1 to 20 wt.% of diluting agent, 0.1 to 15 wt.% of adhesive monomer, 0.1 to 3 wt.% of reducing agent, 0.1 to 3 wt.% of polymerization inhibitor, 0.1 to 2 wt.% of photo-stabilizing agent, 0.1 to 2 wt.% of oxidation inhibitor, 0.005 to 1 wt.% of inorganic dye and inorganic filler, wherein the prepolymer is selected from 2,2-bis£4-(2-hydroxy-3-methacryloxypropoxy)phenyl|propane (Bis-GMA) of formula (1), Tri-GMA of formula (2), a mixture of Bis-GMA and Tetra-GMA of formula (3), and a mixture of Bis-GMA, Tri-GMA and Tetra-GMA.
