Introduction to Mineral Trioxide Aggregate. Mineral trioxide aggregate (MTA) is a are powder primarily composed of tri- and dicalcium silicates with bismuth oxide radiopacifier. MTA has been an addition to the dental armamentarium since the 1. When mixed with water, MTA powder forms hard cement by hydration of the silicates. Because of this bioactivity, the dental community has been intensely interested in this material and its properties, and over 1,0. MTA. The essential calcium silicate compounds in MTA are the same as in Portland cement used in the construction industry, which has been confusing for clinicians. Although the properties of both materials are similar, the Portland cement produced for use in construction industry should not be used as a substitute for MTA clinically. MTA formulas, phases, reactions, and manufacturing are described, with similarities to Portland cement for both grey and white versions. Grey MTA products usually contain a calcium aluminoferrite phase. Otherwise, the white and grey MTA products are very similar chemically, and in vitro or in vivo comparative studies of white and grey commercial dental products have exhibited similar results. No definitive studies have been published showing the superiority of any one MTA- type product over another. Dental standards specifically for testing MTA- type products have not been designed, although several standards for other dental materials have been applied and the results are described.
