A comparative analysis of Mineral Trioxide Aggregate and Portland cement.

The purpose of this study was to compare the composition of Portland cement and Mineral Trioxide Aggregate (MTA). Samples of MTA and Portland cement were analysed for fifteen different elements by inductively coupled plasma emission spectrometry (ICP-ES). Comparative analysis revealed there was significant similarity except there was no detectable quantity of Bismuth in Portland cement. Quantitative results are given in both parts per million (p.p.m.) and wt%. It was concluded that there is no significant difference between the 14 different elements in both Portland cement and MTA.
