INTRODUCTION

The history of mans fight for health begins with his earliest existence when he was completely at the mercy of nature with no effective means of combating its hazards.

Ancient Egyptians used a variety of ways to treats the diseases of the mouth whereas efforts related to prevention of oral diseases dates back to Hippocrates

Then came the process of learning and research in medical and dental field has resulted in a dramatic acceleration in health knowledge but dental diseases continue to be most common diseases and are still progressing

This is because conventional dentistry has traditionally been curative rather than preventive. The need of the hour is the application of evidence based dentistry at the community level

In public health dentistry, the individual patient is not the sole object of study. The entire community is in focus

DEFINITION

1.DENTISTRY

Dentistry is defined as the evaluation, diagnosis, prevention and/or treatment [non surgical, surgical or related procedures] of diseases, disorders and/or conditions of the oral cavity, maxillofacial area and/or the adjacent associated structures and their impact on the human body; provided by a dentist within his/her scope of education, training and experience, in accordance with the ethics of the profession and applicable law.

2. DENTAL PUBLIC HEALTH

“The science and art of preventing and controlling dental diseases and promoting dental health through organized community efforts. Its that form of dental practice which serves the community as a patient rather than the individual. Its concerned with dental health education of the public, with applied dental research and with the administration of group dental care programs as well as the prevention and control of dental diseases on a community basis.”

3. ORAL HEALTH

The World Health Organization (1982) defined oral health as “ The retention throughout life of a functional, aesthetic and natural dentition of not less than 20 teeth and not requiring a prosthesis.”

An alternative definition of oral health given by U.K Department of Health (1994) is “Oral health is a standard of health of the oral and related tissues which enables an individual to eat, speak and socialize without active disease, discomfort or embarrassment and which contributes to general well being.”
