Abstract
Calcium silicate–based root canal sealers have gained increasing attention in endodontics due to their bioactive properties, biocompatibility,
and ability to form a chemical bond with dentin. While their clinical performance in primary root canal therapy has been
widely reported, limited literature addresses the challenges associated with their removal during retreatment procedures. These
sealers, owing to their chemical stability, high bond strength, and penetration into dentinal tubules, may complicate re-access and
complete canal debridement. This literature review examines the current evidence on the retreatability of calcium silicate–based
sealers, with emphasis on the efficacy of various removal techniques including rotary and hand instrumentation, adjunctive use of
ultrasonic and laser systems, and solvent-assisted methods.
