Endodontic retreatment, fiberglass pin installation and composite resin prosthetic rehabilitation: Case report

Abstract

Introduction: Endodontic treatment aims to keep the tooth in proper shape and function, but it may fail, requiring retreatment. This involves the complete removal of the contents of the root canal for disinfection and refilling. The aesthetics and function of the endodontically treated tooth depend on the choice of restorative material, with fiberglass pins being an option that offers superior aesthetics and mechanical properties similar to dentin, providing greater retention and stability of the restoration. Case report: A female patient came to the clinic complaining of loss of restoration of the maxillary canine (13). Radiographic examination revealed an inadequate filling, exposed to the oral environment for a long period. Endodontic retreatment was performed in three sessions, with removal of the previous filling, disinfection of the root canal, and new filling with resin cement. Subsequently, a fiberglass pin was installed, followed by composite resin restoration. The steps included anamnesis, clinical and radiographic examinations, absolute isolation, use of files and solvents to remove the old filling, and application of intracanal medication. After the final filling, the canal was prepared to receive the fiberglass post, followed by the coronary restoration with composite resin. Conclusion: Endodontic retreatment is essential to eliminate bacteria from the root canal, especially in cases of previous failure. The choice of the fiberglass post, due to its biomechanical and aesthetic properties, in combination with the composite resin, proved to be effective in the rehabilitation of teeth with compromised coronary structure, resulting in a functional and aesthetically satisfactory restoration.
