Retreatment of Root Canals Obturated with Bioceramic Sealer: Concept and Techniques
Keywords:
endodontic retreatment, bioceramic sealer, solvents, nickel–titanium rotary files, ultrasonics, supplementary irrigationAbstract
The success rate of conventional root canal treatment is high; however, some cases fail and require root canal retreatment.
Currently, the clinical use of bioceramic sealers has increased due to their favorable physicochemical properties, particularly their
sealing ability. However, they present greater challenges when retreatment is required.
This review article summarizes current strategies and techniques for retreatment of canals previously obturated with
bioceramic sealers, including the use of solvents and supplementary equipment. The combined use of different methods
enhances debridement, minimizes residual obturation material, and may improve the likelihood of successful retreatment.
Keywords: endodontic retreatment, bioceramic sealer, solvents, nickel–titanium rotary files, ultrasonics, supplementary irrigation
