Comparative Evaluation of Compressive Strength of Ketac Molar, Fuji IX and Equia Forte

Abstract

Glass Ionomers have been shown to be a very useful adjunct to restorative dentistry due to their properties such as; biocompatibility with body's hard tissue, long-term fluoride release, low thermal expansion coefficient, good adhesion to moist enamel and dentin without requiring an intermediate agent and low cytotoxicity. Compressive stress results when the body is subjected to two sets of forces in the same straight line but directed toward each other and it is an important property to be considered while choosing a restorative material. FUJI IX and Ketac Molar are two conventional packable high strength glass ionomer cements used to restore teeth in high stress bearing areas. Equia Forte which is a relatively new glass ionomer cement which can be used to restore teeth in high stress bearing areas. It containins ultrafine glass particles and a higher molecular weight Polyacrylic acid. the purpose of the study undertaken was to evaluate and compare the compressive strength of FUJI IX, Ketac Molar and EQUIA FORTE.
