Mineral trioxide aggregate (MTA) was invented in the mid-1990s at Loma Linda University, USA, with the aim of introducing a material for use as a root-end filler that would set and develop its properties in the presence of moisture. MTA is a mixture of Portland cement, used in the construction industry, and bismuth oxide, which is added to enhance the radiopacity of the material. These two components are mixed with water to produce a hydrated cement. Today, other materials based on the original MTA formula have also been manufactured and marketed.
