Abstract:
:A long-standing lesion associated with an undetected perforation of the furca in a mandibular molar was successfully managed using a multidisciplinary treatment approach. The sequence of therapeutic procedures involved conventional endodontic retreatment, an initial orthograde sealing of the perforation, guided tissue regeneration, and a subsequent orthograde resealing of the perforation with Ketac-Endo and Intermediate Restorative Material.
