Comparative Micro-computed Tomographic Evaluation of the Sealing ability of ProRoot MTA, EndoCem Premix MTA, and NeoPutty MTA Apical Plugs in Open Apex Models

Description :

This research investigates the sealing ability, the interfacial adaptation and the presence of open and close voids of three 3 tricalcium silicate materials—NeoPutty MTA, ProRoot MTA, and EndoCem Premix MTA—in orthograde apical plug procedures for apexification. MTA is widely recognized in endodontics for its biocompatibility, sealing capability, and ability to promote tissue regeneration, making it an essential material for treating immature teeth with open apices. However, despite its clinical success, conventional MTA materials, such as ProRoot MTA, are known to present handling difficulties, which can result in voids and compromised seals. NeoPutty MTA, a newer pre-mixed bioceramic material, aims to address these challenges by improving consistency, adaptability, and ease of placement. In contrast, EndoCem Premix MTA offers faster setting times and improved washout resistance, as well as simple placement by injection, making it a viable alternative for single-visit apexification. This study employs micro-computed tomography (micro-CT) to evaluate the voids and sealing integrity of these materials, providing a detailed, non-destructive analysis of their performance within the apical canal. The findings aim to fill existing knowledge gaps regarding MTA performance in orthograde procedures and contribute to optimizing clinical protocols in endodontics.
