Oral cavity is unique from other body cavities as it has a direct communication with the external environment. The oral mucous membrane is exposed to all chemical, mechanical, thermal and biological changes. Initially the physiological adaptation can bear these changes. However, repeated exposure to chemical or biologic carcinogens mechanical trauma coupled with a debilitating state for a longer duration may lead to various changes in oral epithelium. These changes, if left untreated, will lead to increased malignant potential of the tissue.
