Evaluation of Post Obturation Pain Associated With Calcium Hydroxide-based Root Canal Sealers and Resin-based Root Canal Sealer: a Single Visit Root Canal Treatment

endodontic sealer is a material used in root canal therapy to fill the microscopic spaces between the root canal filling material (typically gutta-percha) and the walls of the root canal. Its primary function is to create a tight seal that prevents the ingress of bacteria and fluids into the root canal system, helping to prevent reinfection and promoting the healing of periapical tissues. Endodontic sealers also help to ensure that the root canal filling reaches all parts of the canal, especially in complex or irregularly shaped anatomies.
