Setting time was evaluated following ISO 6876 Standard, radiopacity was assessed by radiographic analysis in millimeters of aluminum, and flow was also evaluated following ISO 6876. Solubility was assessed through mass loss (%) after 7 days of immersion in distilled water, hydroxyl and calcium ions release was measured by pH-meter and atomic absorption spectrophotometer, respectively. Push-out was tested at the universal test machine. The data were statistically compared using a 5% significance level. CEO 1 and CEO 2 showed higher setting times (p&lt;0.05) and all sealers demonstrated radiopacity higher than 3mm\/Al; however, lower radiopacity and flow values were detected in the presence of both experimental sealers when compared with BC and AHPB (p&lt;0.05). No difference was found among all sealers for solubility (p&gt;0.05). BC and CEO 2 had higher pH values at the initial time (p&lt;0.05) while AHPB at the final time (p&lt;0.05). In general, no significant difference between all sealers at all times was observed, except at 168h for CEO 1, which released more calcium ions than CEO 2 (p&lt;0.05). BC and AHPB provided a superior push-out (p&lt;0.05), and cohesive failures were predominant for all sealers. Both experimental sealers exhibited physicochemical properties similar to commercial endodontics sealers.<\/jats:p>","DOI":"10.1590\/0103-644020255937","type":"journal-article","created":{"date-parts":[[2025,7,13]],"date-time":"2025-07-13T17:23:03Z","timestamp":1752427383000},"source":"Crossref","is-referenced-by-count":0,"title":["Evaluation
