Foreword In today’s fast paced world where Perceive…Conceive…Believe…and Achieve are the mantras of success, it is imperative to be using streamlined and consolidated knowledge at every possible step.

The authors of this book are academicians having an impressive track record and an absolute exposure to the course curriculum as well as examination pattern. This publication is impressive in terms that, it is systematically handled wherein there are a set of questions followed by the answers for different chapters in the subject. I am sure that this book will certainly help the student community to excel in their internal assessments and examination for the subject of Preventive and Community Dentistry. I congratulate the authors and wish them all the very best in all their professional endeavors.
