Expanding Potential Dental Applications of Glass Ionomer Cement by Incorporating with Nano-Hydroxyapatite

Glass ionomer cement (GIC) is a common restorative material in dentistry, but it exhibits relatively weak mechanical properties. The present study focuses on incorporating nano-hydroxyapatite (nHAP) with different ratios (1, 3, 5, and 7wt%) GIC to improve its Mechanical properties, sorption, solubility, diffusion coefficients after storage distilled water for 60 days were studied. highest sorption was measured at 7%wt (46.66 µg/mm3), the lowest solubility case of sample containing 5% (29.166 µg/mm3). Moreover, value diffu-sion coefficient 8.5 mm/s nHAP. All all, an ideal nHAP/GIC composition prepared, can be applied as basis underneath dental filling.
