摘要： A dental cement comprises a first paste including a (meth)acrylate monomer having an acid group, the (meth)acrylate monomer not having an acid group, having two or less of hydroxyl groups and/or amino groups and having a molecular weight of 160 or more, the filler having a specific average particle size and being inactive to the (meth)acrylate monomer having an acid group, and the amine compound as a accelerator for the undermentioned polymerizing catalyst; and the second paste including a (meth)acrylate monomer not having an acid group, having two or less of hydroxyl groups and/or amino groups and having a molecular weight of 160 or more, a filler having a specific particle size, and an organic aromatic compound having at least one —SO2— group and the peroxide as a polymerizing catalyst, thereby providing a dental cement large flexural strength, adhesiveness to dentin, small hygroscopic expansion, and low solubility.

摘要： In order to decrease hydroscopic expansion of a resin-modified dental glass ionomer cement without losing high mechanical strength and adhesiveness to tooth structure and to lower a solubility, a dental cement consists of a liquid agent which includes a (meth)acrylate monomer having an acid group; a (meth)acrylate monomer having two or less hydroxyl groups and/or amino groups, not having an acid group, and having 160 or more molecular weight; water if necessary; and an amine compound as a polymerization initiator for a polymerization catalyst in a powder agent, and a powder agent which includes metal oxide powder used for fluoroaluminosilicate glass powder, dental zinc phosphate cement powder or dental carboxylate cement powder; and an organic aromatic compound and a peroxide, where the organic aromatic compound contains at least one —SO2— group as a polymerization catalyst.
