The Essentials of Clinical Periodontology and Periodontics is a learning textbook intended to serve the needs of several groups of dental care professionals and is written with credibility and readability maintained at every level. This book is divided into five parts that include normal periodontium, classification and epidemiology of periodontal diseases, etiopathogenesis, periodontal pathology, and treatment of periodontal diseases, which are further divided into 55 chapters. Clarity and simplicity in language has been my objective of this book. The organization of the chapters and the key points with review questions at the end of every chapter serve as a programmed-guide for the reader. Undergraduate students especially will find it useful in integrating the concepts they have been taught in a more elaborate way.
