Clinical Information
  • 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 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)
