The Successful Interdisciplinary Outcome of Blunderbuss Canal with an Open Apex Using MTA under Magnification: A Case Report.

ABSTRACT

Aim and objective: The present case report aims to describe the nonsurgical management of an anterior tooth with a blunderbuss canal and an open apex using mineral trioxide aggregate (MTA) under magnification. Background: When pulp is traumatized before root formation, it results in pulpal necrosis, due to which dentin and root formation are interrupted. As a result, the canal remains broad due to thin and fragile dentin walls leading to the open apex. Therefore, root canal treatment is a big challenge currently. In such cases, we prefer MTA apexification to form the hard tissue apical barrier, which is a foreseeable treatment and has been used as another advanced method than calcium hydroxide (CaOH2) apexification due to its superior properties. Case description A novel apexification technique was used by the Departments of Pediatric Dentistry and Conservative Dentistry and Endodontics for MTA placement in the central incisor with respect to 11 of a 9-year-old female patient. MTA was used to form an apical barrier using the micro-apical placement (MAP) system under a dental operating microscope (DOM). Following MTA hard set confirmation, obturation with bioceramic sealer and gutta percha with warm vertical condensation was done, followed by post-endodontic composite restoration. Conclusion: This case describes the nonsurgical management of an open apex using MTA, MAP system, magnification, and bioceramics, which aided in the management of this endodontic enigma.
