Pathologies of form and function that affect the oral cavity and its related structures. The mouth, or oral (buccal) cavity, which comprises the lips, tongue, teeth, gums, and related structures, is subject to a large number of disease processes. Periodontitis (an inflammatory disease of the tissues supporting and surrounding the teeth; see illustration) and dental decay (dental caries) are the most common diseases; together, they account for almost all tooth loss. Other diseases of the mouth can be classified as cysts; neoplasms; diseases of the salivary glands; keratotic, inflammatory, ulcerative, and proliferative lesions; oral infections; and an unusual form of rapidly destructive periodontitis observed in some patients with acquired immune deficiency syndrome (AIDS).
