title: Maxillary lateral incisor with two root canals: fusion, gemination or dens invaginatus?
abstract: Endodontic retreatment of a maxillary right lateral incisor with two root canals is described. The diagnosis of fusion, gemination or dens invaginatus could not be made, due to conflicting findings, and to previous root canal treatment that erased the original configuration of the pulp chamber.
