| oral surgical procedures, preprosthetic | Surgery necessary for a denture to rest on a firm base, free from marked osseous protuberances or undercuts, and devoid of interfering muscle attachments, excess mucoperiosteum, hyperplasias, and fibrous or papillary growths. (12 Dec 1998) |

| oral teeth | <dentistry> Your centrals, laterals, and cuspids. These are the teeth in the front of your mouth. (08 Jan 1998) |
| oral ulcer | A loss of mucous substance of the mouth showing local excavation of the surface, resulting from the sloughing of inflammatory necrotic tissue. It is the result of a variety of causes, e.g., denture irritation, aphthous stomatitis (stomatitis, aphthous), noma, necrotizing gingivitis (gingivitis, necrotizing, ulcerative), toothbrushing, and various irritants. (12 Dec 1998) |
| oral vestibule | That part of the mouth bounded anteriorly and laterally by the lips and the cheeks, posteriorly and medially by the teeth and/or gums, and above and below by the reflections of the mucosa from the lips and cheeks to the gums. Synonym: vestibulum oris, buccal cavity, vestibule of mouth. (05 Mar 2000) |
| tuberculosis, oral | Tuberculosis of the mouth, tongue, and salivary glands. (12 Dec 1998) |
| florid oral papillomatosis | Diffuse involvement of the lips and oral mucosa with benign squamous papillomas; microscopically, it resembles verrucous carcinoma, but is not invasive or localised to a specific area of the oral mucosa. (05 Mar 2000) |
| leukoedema, oral | A disorder of the buccal mucosa resembling early leukoplakia, characterised by the presence of filmy opalescence of the mucosa in the early stages to a whitish gray cast with a coarsely wrinkled surface in the later stages, associated with intracellular oedema of the spinous or malpighian layer. (12 Dec 1998) |
| leukoplakia, oral | A white patch seen on the oral mucosa. It is considered a premalignant condition and is often tobacco-induced. When evidence of epstein-barr virus is present, the condition is called hairy leukoplakia (leukoplakia, hairy). (12 Dec 1998) |
| lichen planus, oral | Oral lesions accompanying cutaneous lichen planus or often occurring alone. The buccal mucosa, lips, gingivae, floor of the mouth, and palate are usually affected (in a descending order of frequency).

| azovan blue | <chemical> 6,6'-((3,3'-dimethyl(1,1'-biphenyl)-4,4'-diyl)bis(azo))bis (4-amino-5-hydroxy-1,3-naphthalenedisulfonic acid) tetrasodium salt. An azo dye used in blood volume and cardiac output measurement by the dye dilution method. It is very soluble, strongly bound to plasma albumin, and disappears very slowly. Pharmacological action: dyes. Chemical name: 1,3-Naphthalenedisulfonic acid, 6,6'-((3,3'-dimethyl(1,1'-biphenyl)-4,4'-diyl)bis(azo))bis(4-amino-5-hydroxy-, tetrasodium salt (12 Dec 1998) |
| basic fuchsin-methylene blue stain | <technique> A stain for intact epoxy sections; semi-thick sections of plastic-embedded tissues have nuclei stained purple; collagen, elastic lamina, and connective tissue are stained blue; mitochondria, myelin, and lipid droplets are stained red; cytoplasm, smooth muscle cells, axoplasm, and chrondroblasts are stained pink.
