A nanohydroxyapatite–silica powder was synthesized using an ethanol based sol–gel technique. The synthesized powder was incorporated into commercial glass ionomer powder (Fuji II GC) and characterized using FTIR, 29Si CP/MAS NMR, EDX and XRD spectroscopy. 29Si CP/MAS NMR results showed the presence...
