A disappearing act? Report of an unusual radiographic feature

The clinical presentation of root resorption varies between patients, and occasionally may be a coincidental finding on routine radiographs. Clinical symptoms may be absent but, if present, usually indicate the presence of pulpal disease. The treatment options are determined by the type, site and extent of the resorptive lesion: in some cases, especially where there is external resorption, extraction may be the only option. This article presents a case in which a misdiagnosis of root resorption was made on the basis of persistent clinical symptoms and a diagnostic radiographic finding.
