PROBLEM TO BE SOLVED: To provide a dental cement and a dental cement kit that can provide proper buffering in response to external force.SOLUTION: A dental cement comprises two or more species of 2 functional acrylic monomers having compatibility each other, and under the condition that the two or more species of 2 functional acrylic monomers are polymerized, the percentage of stress relaxation is 10% or more for 0.5 seconds in a compression velocity of 100 mm/minute and a compression displacement of 0.5 mm. The two or more species of 2 functional acrylic monomers are a first 2 functional acrylic monomer and a second 2 functional acrylic monomer having the larger modulus of elasticity than the first 2 functional acrylic monomer. The difference of the modulus of elasticity of the first 2 functional acrylic monomer and the second 2 functional acrylic monomer is 500 MPa or more.SELECTED DRAWING: Figure 4 |
