Dental professionals are exposed to a wide variety of microorganisms in blood and saliva of the patients. These microorganisms can cause infectious diseases. "Prevention is better than cure" - This saying holds true all the more in the field of infection control. The goal of infection control is to provide optimal protection for clinicians and patients from cross contamination in the dental environment.

The science of epidemiology originally referred to the study of epidemics. And epidemic is a frequency of case occurrence beyond that which is usual for the particular season, place, and population group (santwell, 1973). This book is a compilation of all information and studies conducted on epidemiology of gingival and periodontal diseases along with the basics of epidemiology, Which will really help to the students of Periodontology as well as students of Public Health Dentistry in easy understanding of this subject."

It is an all inclusive text book written in chapter wise notes format, written primarily with a vision to help Under graduate as well as post graduate students of dentistry in easy understanding the subject. Salient Features: * Topics covered in a notes format which will help students in easy understanding and revising the subject thoroughly before their University exams. * Some extra chapters are included like, . Evolution and development of Periodontium, Periodontal Indices, Lasers in Periodontics, Nutrition in periodontal disease, Implants - Periodontal consideration, which makes this book unique from other text books available for the same subject.

The research in the field of esthetic and restorative dentistry led to the achievement of the long sought dream of virtually bonding any type of material to the tooth surface. The advances in the restorative materials and bonding techniques have changed the concept of "Extension for prevention" as "Restriction with conviction." The purpose of writing this book is to summarize all information available on this topic under a single text book, to making it convenient for under graduate as well as post graduate students of dentistry.

Despite decades of debate and multiple publications that discuss the theory of occlusion, occlusal design, and equilibration techniques, there have been few well-designed human studies that can help answer the question "does occlusal trauma modify the progression of attachment loss due to inflammatory periodontal disease." The articles reviewed clearly demonstrate that occlusal forces are transmitted to the periodontal attachment apparatus and those forces can cause changes in the bone and connective tissue. Occlusion and its relationship to periodontal disease has been and remains an area of considerable controversy. Over the years, there have been a number of human and animal studies investigating this relationship. The purpose of writing this book is to summarize previous research, describe the signs and symptoms of trauma from occlusion, and discuss treatment considerations.
