Mineral trioxide aggregate: a review of a new cement.
The most common materials in endodontics are gutta-percha and sealer. For certain tasks, however, such as repairing perforations or filling apical preparations, a special-purpose material is needed. The "ideal" special-purpose material in endodontics is still elusive. Most of the materials available today have found their way into endodontics from the restorative field without much consideration of the special conditions and requirements of the periradicular tissues. To address some of the these shortcomings, a material called Mineral Trioxide Aggregate cement (MTA) has been developed at Loma Linda University to seal off the pathways of communication between the root canal system and the external surface of the tooth. At LLU, a series of experiments have been conducted to assess the suitability of this new cement. The experiments began with physical properties of the material and biocompatability studies, followed by clinical studies. The results have been promising, offering for the first time the possibility of regeneration rather than just repair.
