This is the thoroughly revised and updated edition of the book primarily meant for undergraduate dental students. The textbook strives to make the subject simple, concise and easily comprehensible to the readers. This edition features a number of freshly introduced photographs, X-rays and illustrations, meaningful additions such as introduction to cone beam computed tomography, appendix on differential diagnosis based on radiographic appearances, and other useful information. The text of the new chapter on “Advanced Imaging Modalities for Maxillofacial Region” should prove to be extremely useful to the readers in understanding the newer imaging techniques.
