Retreatment Of Endodontically Failed Tooth With Open Apex Using A Matrix Concept - Case Reports

Abstract

An immature tooth with non-vital pulp and periapical pathology imposes a great difficulty to the endodontist. The primary reason for endodontic failure is the persistence of re growth of bacteria within the root canal system and such cases requires retreatment. Endodontic treatment options for such teeth consist of retreatment with conventional apexification procedure with and without apical barriers with the objective of eliminating bacteria from the root canal system with minimum irritation to the periapical tissues and induction of apical closure to produce favourable conditions and to confine the root canal fillings within the canal space. Traditionally, multiple dressings of calcium hydroxide medicament were placed to induce apical barrier formation. This case series describes two clinical cases with open apex and poorly treated root canals which were subjected to apexification procedure using different materials and techniques. The materials used here varied from Biodentine with platelet-rich fibrin (matrix) and mineral trioxide aggregate (MTA) with hydroxyapatite (matrix). Conclusion: Both the cases were successful regarding the resolution of symptoms and periapical healing. No matter what barrier is used or matrix is placed or not, healing takes place if the procedure is followed carefully using recommended protocols. [Kubavat R Natl J Integr Res Med, 2019; 10(6):88-93]
