Plasma cell cheilitis usually involves the lower lip. [3] The lips appear dry, atrophic and fissured. [7] Angular cheilitis is sometimes present. [7] Where the condition involves the tongue, there is an erythematous enlargement with furrows, crenation and loss of the normal dorsal tongue coating. [7]
Normal lips. The lips are normally symmetrical, pink, smooth, and moist. There should be no growths, lumps, or discoloration of the tissue. Abnormal findings are asymmetricality, cyanosis, a cherry-red or pale color or dryness. Diseases include mucocele, aphthous ulcer, angular stomatitis, carcinoma, cleft lip, leukoplakia, herpes simplex and ...
The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth. When found on the floor of the mouth, the mucocele is referred to as a ranula. They are rarely found on the upper lip.
A swelling may arise intra-orally or externally around the face, jaws and neck and can be caused by trauma (hematoma, swelling due to fracture, TMJ dislocation), infection or inflammation. Swelling can occur in the gums, palate, lips, buccal space, etc.
Putting pressure or warmth on the tooth may induce extreme pain. The area may be sensitive to touch and possibly swollen as well. This swelling may be present at either the base of the tooth, the gum, and/or the cheek, and sometimes can be reduced by applying ice packs. An acute abscess may be painless but still have a swelling present on the gum.
The oral mucosa is the mucous membrane lining the inside of the mouth. It comprises 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]
The pulp contains the blood vessels, the nerves, and connective tissue inside a tooth and provides the tooth's blood and nutrients. Pulpitis is mainly caused by bacterial infection which itself is a secondary development of caries (tooth decay). It manifests itself in the form of a toothache. [1]
