| tooth attrition | The wearing away of a tooth as a result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It is chiefly associated with aging. It is differentiated from tooth abrasion (the pathologic wearing away of the tooth substance by friction, as brushing, bruxism, clenching, and other mechanical causes) and from tooth erosion (the loss of substance caused by chemical action without bacterial action).

| attrition |
The loss of subjects during the course of a study. This may be a threat to the validity of conclusions if participants of study and comparison/control groups drop out at different rates or for different reasons. FOR EXAMPLE, if treatment participants fail to appear for treatment and are subsequently excluded from the follow-up, the treatment and control subjects remaining may not be "comparable" due to attrition.
