Objective: To compare and evaluate the rheological and radiographic properties of AH Plus, Endoflas FS, and Pulpdent root canal sealers using a two-plate system and digital imaging technique. Methods: The rheological and radiological properties of endodontic sealing materials were evaluated according to ANSI/ADA Specification No. 57. The two-plate method was used to evaluate the flow properties and film thickness, and the digital imaging technique was used to evaluate the radiopacity. Results: The results show that all three root canal sealers comply with ANSI/ADA Specification No. 57 requirements for all tests conducted for rheological and radiographic properties. There were statistically significant differences among the three test materials. In all of the tests, the AH Plus root canal sealer showed better rheological and radiographic properties than Endoflas FS and Pulpdent. Conclusion: AH Plus root canal sealer had better rheological and radiographic properties than Endoflas FS and Pulpdent root canal sealers.
