Definition

• Dental resorption is the progressive loss of dental hard tissues as a result of clastic activities• It may occur as a physiologic (primary dentition) or pathologic

phenomenon.

In the primary/mixed dentition this is a normal physiologic process resulting in exfoliation of deciduous teeth but in the adult dentition is largely pathological
