moreINTRODUCTION. Mineral trioxide aggregate MTA was developed at Loma Linda University, in the 1990s, as a rootend filling material. It is used primarily to seal lateral root perforations1,2 and as a rootend filling material.36 The use of MTA as a rootend filling material was identified because the material is hydraulic and sets in the presence of water.
