The chemical composition of mineral trioxide aggregate

INTRODUCTION. Mineral trioxide aggregate (MTA) was developed at Loma Linda University, in the 1990s, as a root-end filling material. It is used primarily to seal lateral root perforations[1,2] and as a root-end filling material.[3–6] The use of MTA as a root-end filling material was identified because the material is hydraulic and sets in the ...
