Mineral Trioxide Aggregate

In pulp therapies there has been a change in the technique and medicaments used. Various materials like formocresol 1.2 , gluteraldehyde2 , Zinc oxide eugenol 3 , Calcium hydroxide was considered safe when compared to formocresol, unfortunately this material was found to be delicately balanced between one of repair and resorption. Mineral trioxide aggregate, or MTA, is a new biocompatible material with numerous exciting clinical applications in endodontics. It has been used on an experimental basis by endodontists for several years with anecdotally reported success, some of it quite impressive, MTA¿s approval in 1998 by the U.S. Food and Drug Administration should lead to more widespread use. The material appears to be an improvement over other materials for endodontic procedures that involve root repair and bone healing.
