(a) Back scatter scanning electron micrographs of the test materials showing microstructural features indicating the different chemistry and microstructure (× 1 K magnification). The images show the particle sizing and radiopacifier loading with Biodentine having a smaller particle size when compared to the TCS-ZrO and MTA Angelus and less radiopacifier compared to all materials. (b) EDS area plots of the materials showing the elemental composition. All the materials showed peaks for calcium, silicon and oxygen. (c) XRD plot of the test materials showing the main phases present (CH calcium hydroxide, CT calcium tungstate, TCS tricalcium silicate, ZO zirconium oxide.
