Selective Endodontic Retreatment - An Efficient Therapeutic Approach of Teeth with Missed Canals

It is already known and studied in the endodontic literature that missed canals induce apical periodontitis.Current excellent technical resources for accurate diagnosis, such as Cone-Beam Computed Tomography (CBCT), but also the dental operating microscope make it possible to locate and target missed root canals that are cause of apical pathology, without the need to approach the other canals as well, thus achieving minimally invasive, cost effective and, more importantly, predictable, clinically favorable treatments.The aim of this paper is to provide evidence regarding the clinical efficiency of selective endodontic retreatment, as a conservative treatment alternative of roots with periapical pathosis of multirooted teeth.
