Preface

Caries remains one of the most common diseases throughout the world. It has been classified by the WHO as the third world's health calamity. This book describes the cause, diagnosis, control and prevention of caries, and the progression in daily caries clinical practice, and an increased emphasis on the dental caries in children and secondary caries. The book will appeal to dental students as well as graduate students, dental health educators, hygienists, and therapists. It will also be useful to scientists working in the field of cariology and to qualified dentists who wish to update their knowledge. I wish to thank Ms. Maja Bozicevic and InTech. And an enormous thank to all the contributors who worked overtime to produce their sections.
