In hydrated grey and white Pro-Root, as well as in Angelus and CPM, a more homogeneous, irregular porous image was observed, with some loose granules identified as bismuth, and in CPM bismuth and barium were found Figure 1. Results obtained with energy dispersive spectrometry EDS show that in Portland cement, Group 1, there was presence of Fe, Mg, Na and K Figure 2 and Table III.
