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

 –  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.
