The use of mineral trioxide aggregate to achieve root end closure: three case reports

Abstract

The use of mineral trioxide aggregate (MTA) to achieve root end closure has many advantages over the traditional calcium hydroxide (Ca(OH)2) technique including the reduced number of visits and the reduced mechanical damage to dentine. Limited studies have reported the outcome of using MTA as an apexification material and a one-stage obturation technique in non-vital immature teeth. This article illustrates three successful clinical cases where MTA was used as an apexification material. In case study one: Type 1 Dens Invaginatus tooth with incomplete root formation, case study two: an immature tooth that suffered pulp necrosis following an enamel and dentine fracture trauma and case study three: a non-vital tooth following an apical root fracture.

Keywords: apexification; calcium hydroxide; mineral trioxide aggregate.
