An oral exam is routinely performed by the dentist during the course of an initial comprehensive exam and regular check-ups. An oral cancer exam refers to the identification and management of diseases pertaining to the maxillofacial and oral regions.
The soft tissue of the mouth is normally lined with mucosa, which is special type of skin that should appear smooth in texture and pink in color. Any alteration of the color or texture of the mucosa may signal the beginning of a pathologic process. These changes may occur on the face, neck, and areas of the mouth (e.g., gums, tongue, lips, etc.). The most serious of these pathologic changes (which may or may not be painful) is oral cancer, but there are also many other common pathologic problems.
Geographic Tongue – Also known as Benign Migratory Glossitis or Erythema Migrans, is a condition where the tongue is missing papillae (small bumps) in different areas, and a map-like appearance can develop. This condition is usually seen as red well defined areas on or around the sides of the tongue. The red patches (which can look like an unsightly rash) may come and go from hours to months at a time and cause increased sensitivity to certain substances.
Median Palatal Cyst – This cyst is of developmental origin and is essentially a fluid filled skin sac. It usually appears in the middle of the palate and may cause substantial discomfort.
Hairy Tongue – An overgrowth of bacteria or a yeast infection in the mouth which can cause the tongue to appear hairy and black. This condition is usually a result of poor oral hygiene, chronic or extensive use of antibiotics, or radiation treatments to the head or neck. It is often also seen in HIV positive patients and those who are intravenous drug users. Hairy Tongue may or may not require treatment.
