Abstract
External cervical resorption (ECR) is a relatively uncommon yet aggressive form of
dental hard tissue destruction. It is initiated at the cervical aspect of the root
surface and extends apicocoronally and circumferentially inside the dentin. Despite
the large number of case reports and clinical studies that have investigated ECR,
its etiology remains unclear. Recent advancements in clinical assessment measures,
such as the use of cone-beam computed tomographic imaging, have provided additional
insights into the nature of this lesion. This has facilitated the continued development
and improvement of treatment methods for this condition. In this article, we provide
an overview of the latest research pertaining to the etiology, histopathology, predisposing
factors, diagnosis, classification, and treatment of ECR. Furthermore, we provide
a summary of the different classification schemes for ECR and highlight the relevant
therapeutic principles.
