Textbook of Endodontology – The second edition of Textbook of Endodontology continues the aim of serving the educational needs of dental students and dental practitioners searching for updates on endodontic theories and techniques.
Significantly restructured and completely updated, the new edition maintains the ethos of the original, facilitating ease of learning through pedagogical features such as annotated references, core concepts and key literature. It features a number of new chapters on topics ranging from outcomes of endodontic treatment to managing endodontic complications to dental trauma. Additionally, all other chapters have been thoroughly revised and brought up to date to reflect contemporary knowledge and practice.
Textbook of Endodontology continues its important function of providing lucid scholarship and clear discussion of biological concepts and treatment principles in endodontics, and as such will be an important update to its current readers and a valuable discovery to its new audience.

Textbook of Endodontology – Preface
The Textbook of Endodontology is intended to serve the educational needs of dental students, as well as of dental practitioners seeking updates on endodontic theories and techniques. The primary aim has been to provide an understanding of the biological processes involved in pulpal and periapical pathologies and how that knowledge impinges on clinical management, and to present that information in an easily accessible form. Therefore, we have supplemented the core text with numerous figures and photographs, as well as with boxes highlighting key facts, important clinical procedures and key research. Case studies are given at the end of some chapters in order to further illustrate topics described in the text. In these various ways, the book provides information both at a foundation level, and at a more detailed level for the graduating student and practitioner. The key information boxes are color coded as an easyto-use navigational aid for readers. Core concepts are colored pink, while advanced concepts are purple. Clinical procedures are coded green and key literature boxes are blue. Although not designed to provide a comprehensive review of the literature, this book is also intended to stimulate the reader to delve into the research that forms our current knowledge base in endo dontology. To aid the reader, a selective reference list is provided and comments have been added to especially weighty or useful references. Important and interesting investigations are presented in the core and advanced concept boxes, and we hope that these features will encourage the student to carry on with his or her own exploration of the subject area. This is the second edition of the book, which features three new chapters reflecting the use of the surgical microscope, diagnosis and management of endodontic complications subsequent to dental trauma, and endodontic epidemiology. The dedicated support of our coauthors – 23 highly respected clinicians and scientists – who, in addition to the editors, have contributed to this book, is greatly appreciated. We thank them all sincerely for their time, effort and endurance during the editing process.
The word ”endodontology” is derived from the Greek language and can be translated as ”the knowledge of what is inside the tooth”. Thus, endodontology concerns structures and processes within the pulp chamber. But what about ”knowledge”? What does it actually mean to ”know” things? Most people would probably say that knowledge has something to do with truth and providing reasons for things. It is often believed that dental and medical knowledge is simply scientific knowledge – science is based on research and deals with how things are constructed and work. But as practicing dentists we also need other types of knowledge. Although it is important to know about tooth anatomy and how to produce good root canal preparations for example, we must also develop good judgment and ability to make the ”right” clinical decisions. There are at least three different forms of knowledge that the dental practitioner requires and, in a tradition that goes all the way back to Aristotle, we will refer to the Greek terms for these forms: episteme, techne and phronesis (1).
Episteme – Textbook of Endodontology
Episteme is the word for theoretical–scientific knowledge. The opposite is doxa, which refers to “belief” or “opinion”. There is a massive body of epistemic knowledge within endodontology, for example on the biology of the pulp, the microorganisms that inhabit root canals, the procedures and materials used in the clinical practice of endodontology (endodontics) and the outcome of endodontic therapies. Science produces “facts”. It must be understood that modern science is an industry and is affected by many factors, both internal and external. Although this is not the place to discuss the philosophy of science, the concept of “truth” and the growth of scientific knowledge is not unproblematic. There has been substantial contemporary philosophical discussion reflecting on epistemic knowledge, and the interested reader is referred to one of the many good introductory texts that are available (3). The results of science are presented in lectures, articles and textbooks. So from a student’s point of view the learning situation is rather straightforward, provided that the subject is structured well and ample time given for reading and reflection. This book, in large part, is composed of epistemic knowledge.
Techne – Textbook of Endodontology
The first person to challenge the deeply intrenched theoretical concept of knowledge was the British philosopher Gilbert Ryle. In his book The Concept of Mind (10) he introduces “knowing-how” and distinguishes it from “knowing-that”. “Knowing-how” is practical in nature and concerns skills and the performance of certain actions. This concept of knowledge implies the ability not only to do things, but also to understand what you are doing. To say that you have practical knowledge, it is not enough to produce things out of mere routine or habit. You have to “know” what you are doing and be able to argue about it. Practice must be combined with reflection. The idea that there is a tacit or silent dimension of knowledge has had a great impact on the contemporary discussion. Michael Polanyi, for example, said that “We know more than we can tell” (9).
When trying to explain how we master practical things such as riding a bicycle or recognizing a face, it is not possible to articulate verbally all the knowledge that we have. Certain important aspects are “tacit”. Likewise, it is not sufficient to teach students about root canal preparation simply by asking them to read a book or presenting the subject matter in a lecture. It has to be demonstrated. Knowledge is very often transmitted by the act of doing. A substantial body of endodontic knowledge must be characterized as techne. It is not possible to learn all about the procedures in endodontology by studying a textbook. Observing a good clinical instructor, watching other dentists at work, performing the procedures oneself and reflecting on what has been learned are all important.
