what is the lining of the mouth called
Oral mucosa The oral mucosa is the mucous membrane lining the inside of the mouth and consists of stratified squamous epithelium termed oral epithelium and an underlying connective tissue termed lamina propria.[1] The oral cavity has sometimes been described as a mirror that reflects the health of the individual.[2] Changes indicative of disease are seen as alterations in the oral mucosa lining the mouth, which can reveal systemic conditions, such as diabetes or vitamin deficiency, or the local effects of chronic tobacco or alcohol use.[3]
Dental anatomy The term "crown" of a tooth can be used in two ways. The term "anatomic crown" of a tooth refers to the area above the cementoenamel junction (CEJ) or "neck" of the tooth.[9] It is completely covered in enamel. The term "clinical crown" often is convenient in referring to any part of the tooth visible in the mouth, but as a rule the unqualified term "crown" refers to the anatomic crown. The bulk of the crown is composed of dentin, with the pulp chamber within. The crown is enclosed within bone before the tooth erupts, but after eruption the crown is almost always visible in an anatomically normal and clinically healthy mouth.
