Maxillary permanent central incisor with abnormal crown size and dens invaginatus: case report.

An otherwise healthy young caucasian Australian was referred because of the unusual radiographic appearance of a maxillary permanent incisor. The tooth was found to have an enlarged crown with palatal cusp and dens invaginatus. Over five years' follow-up the tooth showed no signs of pulp necrosis. The major problem was the correction of the patient's esthetics as he approached adulthood.
