- Abraded wound; excoriation or circumscribed removal of the superficial layers of the skin or mucous membrane.
- 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. (from jablonski, dictionary of dentistry, 1992, p2)
