Mineral Trioxide Aggregate. A Better Pulp-Capping Material. Review And Case Report.

Pulp capping is defined as the placement of a dental material over an exposed pulp to initiate the formation of irritation dentin at the site of injury. Classically, different formulations of calcium hydroxide have been used. Today, a newer material is advocated for vital pulp therapy, mineral trioxide aggregate (MTA). It is proved that the exposed dental pulp has the capacity to heal when micro leakage and bacterial contamination are prevented. An effective pulp-capping material should be biocompatible, osteoinductive and it should provide a biological seal and prevent bacterial leakage.This article describes these properties of MTA and a case report of direct pulp capping with MTA in a molar.
