Calcium silicate-based sealers have emerged as a transformative innovation in endodontics, offering solutions to longstanding challenges such as microleakage, biocompatibility, and durability. These sealers demonstrate exceptional adaptability due to their hydraulic setting properties, ensuring tight seals in moist environments and reducing micro-gaps commonly associated with traditional materials. Their bioactivity, characterized by the release of calcium ions and hydroxyapatite formation, promotes periapical tissue healing and enhances the interface between dentin and the sealer, contributing to long-term treatment success. High alkalinity during setting provides sustained antimicrobial activity, effectively inhibiting bacterial proliferation within the root canal system. This property, coupled with low solubility and resistance to degradation, ensures stability and reliability even under challenging clinical conditions. Comparative studies reveal that calcium silicate-based sealers outperform traditional alternatives, such as epoxy resin and zinc oxide-eugenol sealers, in key performance metrics, including sealing ability, biocompatibility, and post-treatment outcomes. Clinically, these sealers are compatible with various obturation techniques, simplifying application while maintaining efficacy in sealing complex canal anatomies. Patients treated with calcium silicate-based sealers report lower incidences of postoperative pain, attributed to their anti-inflammatory properties and enhanced healing potential. Emerging research continues to refine their formulations, addressing limitations like prolonged setting times and optimizing handling properties. The integration of calcium silicate-based sealers into routine endodontic practice signifies a paradigm shift, driven by their ability to improve clinical outcomes and reduce failure rates. As material advancements progress, these sealers hold promises for broader applications in complex cases, further enhancing the predictability and success of root canal treatments. Their superior performance establishes them as a cornerstone in modern endodontic care, addressing both current and future challenges in the field.
