Glass-ionomers
• Most commonly referred to as glass ionomer cements
(GIC's).
• These are materials which consist of an aqueous
polyacrylate and a fluoroaluminosilicate glass.
• These set by an acid-base reaction in the presence of
water.
• These cements appear to adhere to tooth structure by
formation of ionic bonds as a result of chelation of the
carboxyl groups in the acid with the calcium and/or
phosphate ions in the apatite of enamel and dentin.
