Abstract

The initial stages of the reaction between the glass ionomer cement powder and polyacrylic acid solutions (aluminosilicate polyacrylate cement) are described. Polyacrylic acid rapidly decomposes the ion-leachable powder, possibly aided by some metal comPlex-forming function. The amount of fluoride extracted, which is related to its molecular condition in the glass, is of considerable importance.
