With advances in endodontic techniques, increasingly complicated cases are undertaken—with variable results. As a consequence, the majority of procedures carried out by endodontic specialists today are retreatments. This book offers clinically relevant information for overcoming common problems in endodontic treatment. Due to the unpredictable nature of challenging endodontic cases, this is not a step-by-step manual, but rather a compendium of the latest knowledge in the field, including key findings and data from the scientific literature as well as case presentations and practical advice. A valuable reference for endodontists faced with treating compromised endodontic cases.
