Root resorption of a partially erupted tooth: a case report

This article reports a case of a maxillary second premolar which on presentation was partially erupted, and which resisted attempts at orthodontic extrusion. The crown of the tooth was eventually restored using an adhesive composite onlay technique. The patient subsequently complained of pain and the root of the tooth showed radiographic evidence of resorption. The root of the extracted tooth had a vital pulp but massive external resorption was evident, with repair with bone-like material.
