Calcium silicate sealers in endodontics

Introduction: Endodontic root canal sealers serve the purpose of providing a fluid-tight seal, sealing off accessory canals and multiple foramina, while comprehensively confining the bacteria. Of late, rather than seeking a hermetic seal of the root canal, a more biological perspective is being tackled in which, sealers resolve to interact with root dentin, resulting in bioactivity. Tricalcium silicate sealers set the bioactivity in motion on the material surface after contacting the tissue fluids. The Aim: The purpose of this paper is to review the properties of calcium silicate sealers in addition to the recent advances of the same and their clinical applications. Results: Although calcium silicate sealers possess subpar physical properties in comparison to resin-based sealers, they manifest promising properties like biocompatibility, antimicrobial potential along with their propensity for bioactivity. Conclusion: Beneficial properties of calcium silicate sealers render these sealers beneficial in the long-term success of root canal treatment. With newer competent sealers being put forth in the market on a regular basis, it is imperative to study their properties to simplify the clinician's selection of sealer, where indicated.
