This book, in three volumes, is a comprehensive, state of the art guide to the contemporary diagnosis and treatment of temporomandibular disorders (TMDs) that will help to compensate for the frequent lack of experience and inadequate training among health professionals who encounter patients with jaw joint problems. This first volume focuses on fundamentals and the pathways to diagnosis. The opening section describes the whole patient philosophy essential for treatment success, examines ethical and legal considerations, and discusses all aspects of anatomy. Pathophysiology, clinical assessment, and imaging evaluation, including by means of modern MR imaging and CBCT, are then considered in detail. Finally, the diagnostic criteria for the full range of TMDs are thoroughly explained. The complementary second and third volumes are devoted to non-surgical treatment of TMDs and to total temporomandibular joint replacement and other surgical procedures, respectively. Each volume will be of high value for the multidisciplinary team necessary for successful management of TMDs, including dentists, surgeons, primary care doctors, pain doctors, and allied health professionals.
