Dent

A localized impression, hollow, or depression formed on the surface of an object as a result of applied pressure or impact. Dents typically deform the material without breaking it, creating a displacement of fibers or substrate layers rather than a full rupture. In art conservation, dents may appear in paper, canvas, wooden panels, metal objects, or frames, and can be caused by handling, storage pressure, accidental impacts, or contact with protruding objects. Depending on the material and severity, dents may be reversible through controlled humidification, reshaping, or other conservation treatments.
