INTRODUCTION. Mineral xide 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 presence of water.
Mineral xide Aggregate (MTA) is a new material with numerous exciting clinical applications. MTA promises to be one of the most versatile materials of this century in the field of dentistry.
