**Dr. Ali Sultan Al - Refai BDS., MSc. (Oral Biology), PhD. (Anatomy) Department of Oral and Maxillofacial Surgery College of Dentistry Hawler Medical University Erbil, Kurdistan Region of IraqPreface to the first edition Oral Pathology is an important branch of dentistry and although there are few atlases available in the subject, “ A Color Atlas of Oral Pathology For Dental Students” has been written with a views to present the subject to the students in a more simplified but comprehensive manner.

We hope the book will fulfill the need of the students by giving them relevant guidance in their day – to – day learning process as well as during their preparation for examination and above all, with the book in hand, students will feel the subject easy to handle. As no one is perfect in absolute sense. We also humbly accept our limitations regarding shortcomings in the book and therefore we sincerely welcome the valuable suggestions from our senior colleagues and students regarding what further should be done to improve this book in other editions.
