Endodontic Management of Mandibular Premolars with Root Canal Vertucci Type II and III Configuration: Two Case Reports

The location of all root canals (RCs) and their adequate preparation, disinfection, and obturation play an important role in successful endodontic treatment (ET). Furthermore, in addition to normal RC system morphology, the operator should also recognize their anatomical variations. This study presented two cases of mandibular premolars with RC configuration Vertucci type II and III after a clinical diagnosis of irreversible pulpitis. RC preparation in two cases was performed using the crown-down technique. After following the standard irrigation protocol, the RCs were obturated using the warm vertical condensation technique. Knowledge of RC system variations, with their preparation and 3D obturation, is the appropriate qualification for ET.
