I take the privilege to pen a book about OSCE in Periodontics. I believe this book to be one of the first detailed books to be published specifically for OSCE in Periodontics. This book will surely go a long way in guiding the students for their OSCE examinations in Periodontics. From a clinician's point of view, this book will help to come to better diagnostic decisions and will surely play a role in formulating a treatment plan. I had attempted to cover as many topics as possible in this edition. This book is sure to throw new light in the field of Periodontics and will be a handy tool to help students face the OSCE examinations.
