NS-16 - Retreating Bioceramic Sealer-Obturated Canals

As bioceramic sealers are growing in popularity, there is also a rise in the number of cases obturated with bioceramic sealers that need to be retreated. One important goal during retreatment is to eliminate the etiology of persistent disease through the complete removal of the root canal content including the existing root-filling material. Compared to traditional sealers, set bioceramic sealers may be more difficult to remove or bypass with instruments due to their unique physical properties. There is also a lack of effective solvent for set sealers, therefore creating potential difficulties in retreatment. Controversies exist in the literature regarding the effectiveness of bioceramic sealer removal. This presentation will provide a comprehensive review of the available evidence on the retreatment of bioceramic sealer-obturated canals and discuss the clinical tools and techniques to facilitate bioceramic sealer removal.
