Idiopathic external coronal resorption. Case report

External resorption occasionally affects the coronal tissues of unerupted teeth. In young patients these teeth may be interpreted radiographically as being carious. The resorption frequently does not extend to the pulp chamber. Loss of integrity of the reduced enamel epithelium may predispose to these changes. This paper reports the features of an example of idiopathic external coronal resorption.
