The chapter on surgical vs nonsurgical endodontic retreatment provides a good discipline in treatment‐planning. Case selection (i.e., good judgement) is a critical issue because not every case previously treated (and failing) should be retreated; sometimes extraction is indeed the bet- ter choice. The exciting new surgical endodontic technique using a 3D template for guided osteotomy and retro sealing apexes is explained and illustrated here very well—this novel approach will become much more popular once endodontists have the equipment and training to perform these con- servative and effective surgical procedures. I applaud Dr. Chopra for editing this richly illustrated book that should be in the library of every endodontist… and a round of applause to the contributors! Stephen Cohen M.A., D.D.S., FICD, FACD Diplomate, American Board of Endodontics x Foreword Contemporary endodontology is reliant on the sharing of evidence-based knowledge and this atlas adroitly brings together the work of a number of international contributors who are congratulated for collaboratively addressing many of the clinical considerations and challenges faced during endodontic retreatment. The inclusion of QR codes and links to the numerous helpful clinical video clips on the compan- ion website is of significant additional benefit in demonstrating a range of operative procedures. As editor Dr Chopra is to be congratulated for adeptly harmonising this well illustrated resource that will no doubt serve as an excellent reference guide for general practitioners with an interest in Endodontology and in particular to postgraduate students and endodontists who wish to enhance and refine their approach to endodontic retreatment. Rahul Arora MSc, BDS, LDS, FFGDP, FCGDent Dean, Oman Dental College xi Preface When Dr. Viresh Chopra asked me to provide the Preface for his Clinical Atlas of Retreatment in Endodontics, I was very surprised. After all, the Preface is done traditionally by the author himself or herself. However, he had compelling reasons for inviting me, he said. A few years ago, he discussed with me the idea of producing a book on Endodontics. We debated the shape, the form, and the content of the intended book and identified the features that would be of most benefit to busy clinicians in practice. So the Clinical Atlas on Retreatment was born. Retreatment is one of the most challenging areas in Endodontics. By getting contributions from a group of eminent endodontists, this Atlas has enhanced its appeal and its value by providing a broader insight into the management of these failures successfully. Here is the collective clinical experience and the wisdom of fifteen endodontists. There are twenty‐five cases presented in this Atlas, ranging from a perforation of the pulpal floor to cases with multiple failures such as inadequate obturation, fractured instrument, ledge forma- tion in a severely curved root canal and multiple perforations. The cases are varied in their origins, nature, and complexity. The rich illustrations with their accompanying text make it easier to understand the management of these cases by the experts. Dr. Chopra once told me that if his students cannot understand what he is trying to teach, then he has failed. Therefore, he spends a lot of time planning what and how he teaches. The same philosophy has been applied to this book. Please read the Atlas and see for yourself. You will not be disappointed.
