I am extremely happy to present the third edition of Essentials of Clinical Periodontology and Periodontics. In planning the third edition, a firm commitment has been made to provide a thorough and complete text. An attempt has been made to revise and update all the chapters. The highlight of the edition is introduction of KNOW MORE section which contains latest additional information pertaining to each chapter.

Conscious attempt has been made not to disturb the clarity and simplicity of the main text which had gained immense popularity amongst the students. The edition also provides an add on, Manual of Clinical Periodontics which will guide the students in recording case history and performing clinical examination so as to arrive at a proper diagnosis and treatment planning. Also, special emphasis was given to instrumentation which will instruct the students in their clinical work. While describing all these, we have not only mentioned what steps are to be followed but also how to carry out these steps with the help of various illustrations and photographs.

I am grateful to all my colleagues and students who have helped me with their valuable suggestions, which in turn enabled me to write the edition in a more understandable fashion. I hope this book will help the students and practitioners in understanding periodontics in a simplified manner.
