<P>PROBLEM TO BE SOLVED: To provide glass ionomer cement for dentistry capable of improving bending strength without degrading operability in triturating powder and liquid nor impairing transparency of a cement hardened body. <P>SOLUTION: This glass ionomer cement for dentistry includes powder containing, as main constituents. fluoroaluminosilicate glass powder without containing zinc oxide and polycarboxylic acid powder having an average molecular weight ≥5,000 and <50,000, and a liquid containing, as a main constituent, an aqueous solution of polycarboxylic acid having an average molecular weight ≥5,000 and <50,000, wherein the average molecular weight of the polycarboxylic acid in the powder is not smaller than that of the polycarboxylic acid in the liquid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
