Concomitant intrusive luxation and root fracture of a central incisor--report of a case.
A case of a 9-year-old boy who presented with intruded maxillary central incisors, one of which had also sustained a middle third root fracture, is reported. The root fracture was diagnosed after orthodontic extrusion was started, which resulted in separation of the apical and coronal fragments. The hypermobile coronal fragment was stabilised by passing a K file through a palatal access cavity into the root canal of the apical fragment. Orthodontic alignment was completed and the fractured incisors were restored with the file left in situ. At a 10-year follow-up, the incisors were clinically healthy and continued to satisfy aesthetic and functional demands.
