Abstract

This study aimed to evaluate the mechanical strength and the chemical composition of hydroxyapatite glass ionomer cement (HA-GIC).HA-GIC was significantly higher than conventional GIC at the flexural strength and resin modified GIC at the compressive strength. XPS showed the elemental spectra of Ca and P in the HA-GIC and HA100-GIC. The ratio of Ca/P in HA-GIC hydrogel matrix was different from pure hydroxyapatite. It suggests that the chemical reaction was occurred between hydroxyapatite and GIC.
