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.
本研究的目的是比较波特兰水泥和三氧化矿物凝聚体（MTA）的成分。采用电感耦合等离子体发射光谱法（ICP-ES）对MTA和波特兰水泥样品中的15种不同元素进行了分析。对比分析表明，二者存在显著相似性，只是波特兰水泥中未检测到铋元素。定量结果以百万分之一（ppm）和重量百分比（wt%）给出。得出的结论是，波特兰水泥和MTA中的14种不同元素之间没有显著差异。
