University Japan Foreword It gives me immense pleasure to introduce you to the third edition of the Textbook of Endodontics Past several years have witnessed the publication of many new textbooks on the subject of endodontics by well-known scholars and scientists Several critically important paradigm shifts have occurred in dentistry, particularly in the field of endodontics in the past decades, a shift towards the comprehensive approach in the endodontic practice today It is of foremost importance to put this work into the context of the continuum of endodontic literature Endodontics has become so important in the last several decades that books which condense all the techniques and treatment options are certainly looked-for Written by the two leading authorities on this important aspect of dentistry, Drs Nisha Garg and Amit Garg have accumulated a tremendous amount of knowledge to summarize this important information into easy-to-read chapters This compact yet comprehensive work clearly portrays their efforts The authors have invested extensive time and effort to freshly describe the existing literature and have added interesting chapters like Endodontic Failures and Retreatment, Tooth Hypersensitivity, and Tooth Infractions I am sure the new edition of the book will be equally appreciated by the undergraduate and postgraduate students as well as the researchers I am delighted and honored to introduce and recommend the book, which will effectively bridge the gap between the scientific esoteric and practitioner’s daily need for relevant knowledge, and will become one of the most significant steps in understanding the subject of endodontics.
