Abrasion

Abrasion, a superficial injury to the skin or mucous membranes. A skinned knee or elbow are examples. Most abrasions come under the category of minor injuries, occurring in commonplace everyday situations. Nevertheless, abrasions should not be taken lightly, as they are higly susceptible to infection. Cleansing with soap and water is usually sufficient protection. If much bleeding or oozing of fluid takes place, the abraded area should be covered with sterile gauze after it is cleaned. In dentistry, abrasion refers to the wearing away of tooth surface caused by chewing.
