| abrasion | 1. <pathology> The wearing away of a substance or structure (such as the skin or the teeth) through some unusual or abnormal mechanical process. 2. <clinical sign> A superficial injury to the skin or other body tissue caused by rubbing or scraping resulting in an area of body surface denuded of skin or mucous membrane. (11 Nov 1997) |
|---|---|
| gingival abrasion | A lesion of the gingiva resulting from mechanical removal of a portion of the surface epithelium. (05 Mar 2000) |
| mechanical abrasion | <procedure, surgery> A surgical procedure which involves the controlled abrasion of the upper layers of the skin to smoothen the skin and remove wrinkles, small scars or foreign bodies (tattoos). (27 Sep 1997) |
| tooth abrasion | The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from tooth attrition in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from tooth erosion, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action. (12 Dec 1998) |
| vascular dentin | Dentin in which the primitive capillaries have remained uncalcified and so are wide enough to give passage to the formed elements of the blood. Synonym: vascular dentin. (05 Mar 2000) |
| reparative dentin | Morphologically irregular dentin formed in response to an irritant. Synonym: irregular dentin, irritation dentin, reparative dentin. (05 Mar 2000) |
| peritubular dentin | An electron-dense layer of dentin observed adjacent to the odontoblastic process. (05 Mar 2000) |
| primary dentin | Dentin which forms until the root is completed. (05 Mar 2000) |
| hereditary opalescent dentin | Synonym: dentinogenesis imperfecta. Synonym: opalescent dentin. (05 Mar 2000) |
| sclerotic dentin | Dentin characterised by calcification of the dentinal tubules as a result of injury or normal aging. Synonym: transparent dentin. (05 Mar 2000) |
| secondary dentin | Dentin formed by normal pulp function after root end formation is complete. (05 Mar 2000) |
| hypersensitive dentin | Exposed dentin at the cervical portion of a tooth, painful to touch, sweetness, or temperature changes. (05 Mar 2000) |
| dentin | <dentistry> The calcified tissue below the enamel, enclosing the cavity of the tooth containing the pulp chamber and root canals. (08 Jan 1998) |
| dentin-bonding agents | Cements that act through infiltration and polymerization within the dentinal matrix and are used for dental restoration. They can be adhesive resins themselves, adhesion-promoting monomers, or polymerization initiators that act in concert with other agents to form a dentin-bonding system. (12 Dec 1998) |
| dentin bridge | A deposit of reparative dentin or other calcific substances which forms across and reseals exposed tooth pulp tissue. (05 Mar 2000) |
