Preface

This book begins by describing the 30 most common conditions that a dentist or physician may encounter when patients present with orofacial pain and dysfunction (not due to a dental infection). Chapter 1 provides a short description of the clinical characteristics of these 30 conditions. The majority of these conditions are also described in greater detail along with recommendations about the best evidence-based treatment approach in Chapters 12 through 20. Chapter 2 introduces the 60 most common medications that are used by clinicians who treat orofacial pain. These medications and how they are used are then described in detail in Chapters 3 through 11.

In all instances we have attempted, where possible, to collect and present the scientific evidence that supports or refutes the use of a specific medication for a specific condition. Obviously this book has a clear focus on medications because so many of the pain disorders that occur in the orofacial region are treated with medications. However, this focus should not diminish the fact that there are several other options that should be used in combination with medications, including behavioral (psychosocial) and vari­ous physical medicine methods. These interventions can help a patient gain a sense of control over his or her pain and should be introduced early in the course of pain management.

The creation of a body of work such as this takes a good deal of time and effort. First we want to thank our spouses for the support and tolerance they have given us during this effort. Next we thank all of the chapter authors, all of whom are good friends and colleagues who trusted us to produce a book that they would be proud to have contributed to. Finally, at the end of Chapters 3–20 we provide a few key recommendations based on the content covered in these chapters. We have put all of the tables, figures, and end-of-chapter recommendations in a website maintained by Wiley (our publisher) for anyone who has enough curiosity to go to the website (www.wiley.com/go/clarkdionne). As an added benefit we have included a set of 187 questions and answers that should be valuable to the readers. We hope this website is considered a valuable addition to the book.
