Periapical Lesions

The present study aims to compare the radiographic success of endodontic treatment using Orstavik's criteria between two sealers: AH Plus (Dentsply DeTrey, Konstanz, Germany) and Neosealer Flo (Avalon Biomed, Bradenton, Florida, USA), as well as between two obturation techniques: continuous wave and single cone. The study includes 270 patients, with a minimum follow-up period of 6 months. Clinical and radiographic variables will be assessed, including quality of obturation, lesion healing, and restoration. The study seeks to determine if the use of bioceramic sealer is effective regardless of the obturation technique used, highlighting the importance of clinical follow-up to evaluate endodontic treatment success.

The Bone window technique provides excellent access to the surgical site while preserving cortical bone in cases of tooth with large periapical lesion and an intact cortical plate. Traditionally, rotary burs and a bone chisel were used to create a bone window. Piezoelectric bone surgery, on the other hand, is an innovative technique that uses thin osteotomy instrument to selectively cut hard tissue while preserving soft tissues. To the best of our knowledge, no study comparing the results of a bone lid using a piezoelectric device and a conventional bur is currently available.
