Evaluation Of Radiopacity of Nanoparticle Incorporated Root Canal Sealer with Epoxy Resin Incorporated Root Canal Sealers – An Invitro Study

Aim: of this study was to assess and compare, the radiopacity nanoparticle-based (NPB) root canal sealers with Epoxy Resin Based(ERB) sealer using an aluminium step wedge in accordance ISO 6876/2012 standards. Materials methods: The specimens, which were made each material, had a 10mm diameter 1mm thickness. creation metallic matrices, used fabrication impressions, done light-bodied silicone-based impression medium. Using step-wedge, NPB ERB assessed international optical density measured sample enamel, dentin, appropriate thickness, all measuring 1 mm thick. Results: 2.37, minimum value 179 maximum 215. for 3.47, 185 255. Conclusion: Within limits study, has better than sealers. It values are within ADA/ISO recommendations. Clinical Significance: can be compared other commercially available vivo applications. Bangladesh Journal Medical Science Vol.22 (Special Issue) 2023 p.63-66
