COMPARISON OF THREE BIOCERAMIC SEALERS IN TERMS OF DENTINAL SEALING ABILITY IN THE ROOT CANAL

Objective: The main objective of endodontic treatment is to prevent further infection or reinfection by eliminating microorganisms within theroot canal system. Proper endodontic treatment could prevent apical and coronal penetration of fluids and microorganisms. Endodontic sealer isvital components of root canal obturation to establish a fluid-tight seal. Bioceramic-based root canal sealers are considered to be an advantageoustechnology in endodontics and have been found to be both biocompatible and comparable to other commercial sealers. The aim of this study was tocompare the adhesion of three bioceramic sealers within the root canal system.Methods: Endodontically treated teeth were obturated using three types of bioceramic sealers and then divided into three groups. Specimens werethen observed using a scanning electron microscope, and the attachment distance was measured using ImageJ.Results: The three groups exhibited were statistically significant differences (p<0.05) in dentinal sealing ability. Calcium phosphate silicate-basedsealer showed the highest sealing ability, followed by pure tricalcium silicate-based bioceramic sealers and then tricalcium silicate and resin-basedbioceramic sealers.Conclusion: The sealing ability of calcium phosphate silicate-based sealer is superior to that of both pure tricalcium silicate-based and tricalciumsilicate- and resin-based sealer
