Preventive Dentistry

Introduction

Oral health means not only being free of oral diseases but also being able to perform proper oral functions. Basic oral functions such as eating, speaking and laughing are essential for fully expressing oneself and achieving self-realization. Preventive dentistry aims to help people lead a full-fledged life by keeping their oral conditions healthy and optimal so that they can maintain a wholesome life style throughout life.

The typical image of preventive dentistry has been that of preventing dental caries and periodontal diseases. From the overall perspective of systemic health, however, this only represents a fraction of the means of health promotion. Preventive dentistry integrates with the primary prevention (to be healthy and to prevent initial sickness), the secondary prevention (to prevent illness from getting worse) and the tertiary prevention (to recover and restore the original functions). Thus the philosophy of preventive dentistry is required for everyone who engages in oral health care and treatment.

The division of preventive dentistry investigates oral health and healthcare issues from the standpoint of individuals and communities as a whole.
