A randomized, interventional, prospective, unicentric clinical study, 86 patients will be submitted to endodontic treatment of necrotic teeth. 43 patients will complete treatment with obturation with AHPlus cement and Gutta-Percha cones (group A) and 43 patients will complete treatment with PBS® CIMMO cement (single material) (group B). The primary outcome will be the repair of the periradicular lesion demonstrated by integrity of the hard blade throughout the perimeter of the root identified by Tomography Cone Beam, performed after 6 months of treatment. The secondary endpoint will be the absence of fistula after 6 months of treatment identified by clinical examination.
