SEALING THE FUTURE: APEXIFICATION WITH BIODENTINE A CASE REPORT

The root growth is a gradual phenomenon and a root apex closure takes place for up to three years after the tooth eruption. If some damage to the tooth occurs during this period, it will impede the root apex closure process. The root canal with thin and delicate walls is therefore wide and the apex is always open. This impairs the instrumentation of the root canal and prevents an appropriate apical stop. It is essential that an artificial apical barrier is created, or the apical foramen is closed with calcified tissue to permit the condensation of the filling material and to facilitate apical sealing in such cases. The apexification of premature permanent teeth with open apices may be a feasible alternative.Apexification is an endodontic procedure designed to induce apical closure in nonvital immature permanent teeth with open apices by stimulating hard tissue formation and presents a unique challenge to dental professionals.2In the past,calcium hydroxide was commonly used in apexification, but it has disadvantages, including questionable tissue apposition, high solubility, low push-out bond strength, the potential for voids, and an inability to create a reliable apical barrier.3To address these limitations,mineral trioxide aggregate(MTA)emerged as a biocompatible alternative, forming a monoblockbarrierthat promotes cementum deposition, though its extended setting time remains a drawback.
