SP-12 - Clinical Outcome of Non-surgical Root Canal Treatment and Retreatment of Teeth with Apical Periodontitis Using Cold Hydraulic Condensation with Bioceramic Sealer: A Retrospective Analysis

Presentation Description/Abstract: The obturation of the root canal system is a critical step of the non surgical root canal treatment in order to achieve a positive outcome of the therapy: as a matter of fact an high percentage of endodontic failures are associated with incomplete root canal obturation and apical periodontitis presence.
The possibility to get a fluid-tight seal is crucial to prevent percolation of bacteria and it depends on the properties of the sealer and on the obturation technique.
Hydraulic Calcium silicate-based sealers properties are driving a paradigm change in obturation towards a more sealer-centric philosophy.
The purpose of this presentation is to evaluate the outcome at 2 years of non surgical canal treatments done in a private practice between 2017 and 2021 in teeth with apical periodontitis. All cases, including initial and retreatment, were obturated with bioceramic sealer and CHCT independently of the endodontic anatomy. Outcome was evaluated based on clinical and radiographic findings at recall, with a minimum 2-years follow-up for 525 teeth. Teeth were classified as healed or healing (success), or not healed (failure). Patient and treatment factors were analyzed to determine their significance as prognostic factors. Among the factors even apical size bigger than 50, sealer extrusion and presence of small perforations. The results obtained support the conclusion that the use of bioceramic sealers with the CHCT is a valide option for obturation in text with apical periodontitis.
