Developing teeth with necrosed pulp and periapical pathologies are complicated to treat by conventional endodontic treatment. Conventionally, calcium hydroxide has been the material of choice for the apexification of developing permanent teeth but apexification with calcium hydroxide is seems to be associated with certain difficulties that include treatment time and tooth fracture. Apexification is a method by which artificial barrier in the root apex is formed in such a way that obturating material can be filled in the canal space. MTA has shown good sealing abilities and biocompatibility to the periradicular tissue. Single visit apexification using an apical plug of novel biocompatible material like mineral trioxide aggregate (MTA) has been indicated as an alternative to long-term intracanal use of calcium hydroxide in immature permanent teeth. This paper highlights the successful management of re-implanted teeth by single visit apexification using collacote and MTA.
