Abstract

Root canal sealers are crucial components in endodontic therapy, ensuring the hermetic sealing of the root canal system. Their primary function is to fill the voids and irregularities between the dentinal walls and the core filling material, thereby preventing microleakage and subsequent reinfection. Various types of sealers, including zinc oxideeugenol- based, calcium hydroxide-based, glass ionomer-based, resinbased, and bioceramic-based, have been developed, each with unique properties and clinical applications. The ideal sealer should exhibit excellent sealing ability, biocompatibility, antimicrobial properties, ease of handling, and radiopacity. Recent advancements have focused on enhancing the biological and physical properties of sealers, particularly through the incorporation of bioactive materials that promote healing and regeneration. Studies have shown that bioceramic sealers offer superior biocompatibility and the ability to form hydroxyapatite upon contact with tissue fluids, facilitating the repair and regeneration of periapical tissues. Additionally, the antimicrobial efficacy of sealers remains a critical factor in preventing endodontic treatment failures. Ongoing research is directed toward optimizing the formulations of sealers to improve their performance and clinical outcomes. This abstract underscores the significance of root canal sealers in endodontics, highlighting the evolution of materials and the continuous quest for the ideal sealer to enhance the success rates of root canal treatments.
