Success of Endodontic Treatment With Different Obturation Techniques and Sealer Cements

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.

Evaluation of Bone Regeneration After Apical Surgery Using Advanced Platelet-rich Fibrin: Utilization of Ultrasound for the Assessment of Periapical Lesions

The study examines the impact of advanced platelet-rich fibrin (A-PRF) on bone regeneration in apical surgery compared to standard methods. It highlights the effectiveness of ultrasound as a diagnostic tool for assessing periapical lesions. Eligible participants were adults with specific periapical lesions following root canal treatment failures. Exclusions included patients outside specific criteria, like those with advanced periodontal disease or undergoing orthodontic treatment. Participants were randomized into two groups: one receiving A-PRF to enhance bone regeneration and a control group without it. Both groups underwent apical surgery under magnification, with different postoperative protocols. The study involved radiological and ultrasonographic evaluations of lesion size and bone healing at baseline, 6 months, and 12 months, alongside blood analyses for Vitamin D and cholesterol level to assess their potential impact on healing.

Outcome of Bone Window Approach in Endodontic Microsurgery Using Novel Piezoelectric Device

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.
