Abstract

An aspect of the present invention relates to a dental cement that includes a first agent including an organic peroxide and a (meth)acrylate; and a second agent including a thiourea derivative, an ascorbate, a vanadium compound, and a (meth)acrylate, where the first agent and the second agent each have a water content that is less than or equal to 1 mass %.

First claim

The invention claimed is:

1. A dental cement comprising:
a first agent including an organic peroxide and a (meth)acrylate; and
a second agent including a thiourea derivative; an ascorbate selected from among sodium ascorbate, calcium ascorbate, potassium ascorbate, and stereoisomers of sodium ascorbate, calcium ascorbate, and potassium ascorbate; a vanadium compound; and a (meth)acrylate;
wherein the first agent and the second agent each have a water content that is less than or equal to 1 mass %,
the first agent includes 0.1 mass % to 2 mass % of the organic peroxide,
the second agent includes 0.1 mass % to 1 mass % of the thiourea derivative, 0.1 mass % to 1 mass % of the ascorbate, and 0.01 mass % to 0.1 mass % of the vanadium compound.
