Aim:
Endodontic retreatment procedures using bioceramic sealers are gaining increasing credibility in tackling clinically challenging cases. The objective was to compare the retrievability of bioceramic sealers and epoxy resin-based sealers.
Methods:
The study protocol, registered in the International Prospective Register of Systematic Reviews and adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 checklist, involved an electronic search for English-language studies from 2010 to 2023. Database used for searches were PubMed, Web of Science, Research Gate, Google Scholar, Scopus. The inclusion criteria were established based on the PICOS framework.
Studies involving artificial teeth, animal models, expert opinions, conference abstracts, book chapters, case reports, in vivo research, and narrative reviews were not considered for inclusion. The risk of bias was assessed using Quality Assessment Tool For In Vitro Studies (QUIN) Tool.
Results:
Eleven studies were categorized as low risk and eight studies as medium risk of bias. The study results were mixed with some showed that bioceramic sealers were easier or harder to remove, while others found no difference. The studies varied in the type of bioceramic sealer used, root canal anatomy, and retreatment techniques.
Conclusion:
Retreatment of canals with bioceramic sealers is usually possible with standard instruments and techniques. Additional removal methods like lasers, XP-Finisher, and ultrasonics enhance the process
