Abstract
A new dual-cured resin sealer has recently been proposed as an innovative endodontic filling material. Being a new endodontic material, no in vitro research has been published yet on Real Seal's (RS) physical properties. Therefore, the aim of the present study was to evaluate and compare radiopacity and rheological properties of the RS sealer with those of currently available endodontic sealers (Roeko Seal Automix and Bioseal). All tests strictly followed American National Standards Institute/American Dental Association (ANSI/ADA) specification No. 57, which indicates test methods and establishes minimal requirements of flow, film thickness and radiopacity of endodontic sealers. Results showed that significant differences were found among sealers in the different test methods. However, RS showed values complying with ANSI/ADA specification No. 57 requirements in all tests. Hence, the new RS sealer exhibited radiographic and rheological properties suitable for clinical use.
