Management of Endodontic Failure
Programme outline: Rational behind non-surgical endodontic retreatment. Disassembly of commonly used obturation materials. Removal of obturation materials. Disinfection during retreatment. The 3-dimensional anatomy of root canal systems and its relation to root canal treatment failure. Outcome studies on non-surgical root canal treatment. Management of broken endodontic instruments. Calcium silicate cements and their application during non-surgical retreatment. Microsurgical Endodontics. Local anesthesia for surgery, flap design, osteotomy preparation, root-end resection and retrograde preparation with microsurgical instruments, precision root-end filling with calcium silicate cements and putty, and suturing techniques.
Hands-on training: Re-treatment of common endodontic obturation materials. Removal of gutta-percha fillings. Removal of carrier-based materials. Removal of fiber posts. Broken instrument removal and bypassing. Pulp floor perforation repair. Internal resorption defect management. Apical plug placement. Hands-on training using 3D printed special tooth models, sheep cadaveric specimens and microscopes.
DAY 1
Title: Non-surgical Retreatment
Aims
To understand the rationale behind non-surgical retreatment approaches and the aitiology of initial root canal treatment failure. To present an evidence-based framework for the safe and effective disassembly of non-obturation and obturation materials.
Objectives
Students will be able to remove guttapercha obturations from root canals, remove Carrier based obturations from the root canals, remove paste obturations and remove fiber posts. Students will have the opportunity to use most of the current technology used during retreatment procedures.

DAY 2
Title: Non-surgical Retreatment
Aims
To understand the factors related to the long-term outcome of non-surgical endodontic retreatment and to develop a rational diagnostic and decision-making framework. To appreciate the importance of magnification and illumination for the management of complicated non-surgical retreatment cases.
Objectives
Students will be able to bypass and remove broken endodontic files and understand all the preventive measures to avoid complications during endodontic instrumentation. The students will be able to repair a pulp floor perforation, to obturate an internal resorption defect and perform apical plugs with biocompatible materials.
