The use of a biocompatible cement in endodontic surgery. A randomized clinical trial 1.

Purpose: To evaluate the clinical applicability of Pozzolana Biologic Silva cement (PBS(r)) in endodontic surgery.

Methods: Persistent apical periodontitis was diagnosed in 30 teeth of 12 patients by cone-beam computed tomography (CT). All patients had 2 or 4 affected teeth and underwent endodontic surgery with root-end filling.

Portland cement versus MTA as a root-end filling material. A pilot study.

Purpose: To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material.

Methods: Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling material, patient B was treated with Portland cement and patient C had two teeth treated, one with MTA and the other with Portland cement.
