The length of training for dental undergraduates has gradually been increased in order to strengthen the scientific basis of dentistry, which means that students are now more analytical and ready to question clinical procedures that are not based on sound principles. Over the years 'Endodontics in Clinical Practice' has become accepted as an authoritative guide to proven clinical practice. Regarded as a classic in its field, 'Endodontics in Clinical Practice' is primarily intended as an undergraduate text for dental students although dental practitioners will also find it invaluable when used in their day to day practice. This new edition has been retitled in honour of Fred Harty, the original author who was tragically killed just prior to publication. His foresight and knowledge have provided a book that has become an essential component of every dental student's armamentarium. His designated successor, Tom Pitt Ford, Reader in Endodontology at UMDS, has thoroughly revised the text and brought in a number of new authors to give the fourth edition international appeal. The aim of 'Harty's Endodontics' is not only to provide an essential undergraduate text but also a handbook that will enable busy practitioners to update themselves on a growing specialty. This fourth edition continues to fulfil that already proven role. It has been the editor's intention not only to provide a practical handbook but also to provide a text that will support courses in continuing professional education, the importance of which is now stressed by the profession as a whole.
