Abstract
This review explores the field of retreatment strategies for the cases filled with calcium
silicate-based root canal sealers. Since the introduction of calcium silicate-based materials in dentistry,
calcium silicate-based root canal sealers have become popular among dentists because of their biocom-
patibility, bioactivity, and sealing ability. Therefore, effective retreatment strategies are indispensable.
This article aims to identify the challenges associated with the removal of calcium silicate-based
sealers itself and gutta-percha with the sealers during retreatment, evaluate current techniques and
materials, and provide future directions for research in this field. Regarding the strategies of removal
of root canal sealers, calcium silicate-based sealers are still relatively new materials for clinicians
compared with the traditional sealers such as epoxy- or eugenol-based sealers. First, no clinically
established solvents have been reported. Second, calcium silicate-based sealers are currently utilized
by clinicians in either cold sealer-based technique or warm vertical condensation technique. Third, the
setting process of calcium silicate-based sealers generates byproducts primarily calcium hydroxide
and secondarily hydroxyapatite, which could interact with dentine. Lastly, there is a lack of clinical
studies evaluating the efficacy of retreatment protocols for teeth filled with calcium silicate-based
sealers. Therefore, it is important to investigate chemo-mechanical properties of calcium silicate-
based sealers itself and their reactions to solvents and/or mechanical instruments, and identify the
interfacial properties of calcium silicate-based sealers in respect to dentine and gutta-percha. In
addition, researchers in clinical field need to actively gather and report data on retreatments of teeth
filled with calcium silicate-based sealers.
