Abstract: Four polyacids were prepared by reacting acrylic acid with itaconic and maleic acids at different ratios and these were treated with a fluoroalumino calcium silicate glass to form polyalkenoate cements. The effect of working time and setting time of the glass ionomer upon addition of a chelating agent (+) tartaric acid into the polyacid has been studied. Mechanical properties such as compressive strength and diametral tensile strength were found to improve-upon addition of 5% by weight of the chelating agent. The monomer ratio in the polyacid was also found to be critical in determining the final properties of the dental material.
