Hydraulic calcium silicate–based sealers have become widely used in modern Endodontics due to their excellent biocompatibility and bioactive properties. These materials set in the presence of moisture and release calcium ions, which promote mineralization and support periapical healing. Their alkaline pH provides antibacterial effects while maintaining compatibility with surrounding tissues. In addition, hydraulic calcium silicate–based sealers exhibit superior dimensional stability and minimal shrinkage, contributing to improved sealing ability of the root canal system. Their ability to penetrate dentinal tubules and form a chemical bond with dentin enhances long-term sealing performance. Consequently, these sealers represent a significant advancement in achieving predictable and biologically favorable endodontic outcomes.
