A case of Invasive Cervical Root Resorption in a 12 y.o. female patient.

Invasive Cervical Root Resorption (ICRR) has a poor known aetiology, compared with typical external root resorption it appears very aggressive, posing a high risk of tooth loss. ICCR is often misdiagnosed, the resorption is caused by cells of the peridontium penetrating the outer surface of the root in the cervical region, spreading out throughout the root dentin. ICCR is usually detected in the adulthood on permanent teeth, anyway in a small amount of cases is possible to observe ICCR on impacted permanent canines during the adolescence and first adulthood.The aim of this paper is to present our experience with a ICCR case occurred in a young woman previously treated for an impacted canine with orthodontic therapy.
