Invasive cervical resorption: a case report.

Invasive cervical resorption (ICR) is a relatively uncommon form of external resorption, which may occur in any tooth in the permanent dentition. Characterized by its cervical location and invasive nature, this resorptive process leads to progressive and usually destructive loss of the tooth structure, the clinical features of which often resemble internal resorption ("pink tooth"). This article describes a case report of ICR and its management. The salient features were a large resorptive defect and localized fibrous in-growth located almost wholly on the cervicolabial aspect of the maxillary incisor crown involving the enamel and dentin.
