Textbook of Oral Diagnosis is a concise book that is primarily targeted to the undergraduate students of dentistry. With contributions from a team of international medical and dental teachers, this book provides a systematic and sequential approach to the study of diagnosis and the diagnostic process. Divided into two sections, the first section of the book deals with the various aspects of clinical methods, documentation, and fundamental concepts of treatment planning; the main focus is on traditional methods of diagnosis. The latter section of the book is primarily focused towards the different approaches that are available to a diagnostician. The topics discussed meet with the curricular requirements of most universities in the world. This textbook would also prove to be useful for clinicians, teachers of dentistry, dental nurses, and those preparing for postgraduate and National Board examinations.
