MTA is a powder mixture of Portland cement clinker, bis- muth oxide, and gypsum. It has gained a lot of importance in dentistry in recent years. This importance is because of its extensive use as apical restorative ma- terial as well as a medicament for Apexogenesis and Apexification treatment. As it sets by hydration process, the by products of insoluble calcium silicate hydrate and alkaline calcium hydroxide offer unique stability and potential to enhance hard tissue regeneration. This article reviewed the composition, types, properties of MTA and also its applications in the clinical dentistry.

Mineral Trioxide Aggregate: An overview of composition, properties and clinical applications. Int J Dent Mater 2020;2(1): 11-18. DOI: htp://dx.doi.org/10.37983/IJDM.2020.2103 1. Introduction Mineral Trioxide Aggregate (MTA) was first introduced in the year 1993 by Mohmoud Torabinejad at Loma Linda University in California, USA. MTA has been used on experimental basis by many endodontists for several years. Final- ly, it was approved for human usage by the U.S. Food and Drug Administration [FDA] in the year 1998[1,2]. MTA appears to be an improvement over other materials for some endodontic procedures that involve root repair and bone healing. This MTA is the only material that supports overgrowth of cementum and formation of bone. MTA has both dentinogenic and osteogenic potential [3,4]. Newly developed fast-set MTAs were produced by Pozzolan cement or Zeolite cement. Pozzolan cement is a mineral aggregate with watery calcium silicate hydration. This review aimed to conduct an updated search on the com- position, manipulation, types, properties, disadvantages, and clinical applica- tions of MTA. These materials exhibit excellent biocompatibility. MTA provides better protection against microleakage than traditional endodontic repair ma- terials which can be identified using dyes, fluid filtration and bacterial penetra- tion leakage models [4].
