Purpose: To evaluate the physicochemical properties of the epoxy-resin based root canal cement Sealer 26®, enhanced with different amounts of iodoform. Methods: The properties of setting time, radiopacity, flow, solubility and dimensional stability were measured according to ANSI/ADA Specification 57 for sealing materials. The samples were divided into five groups: (I) Sealer®; (II) Sealer®+5% iodoform; (III) Sealer®+7% iodoform; (IV) Sealer®+10% iodoform; (V) Sealer®+30% iodoform. Five samples were prepared from each group, for each test. Results: Statistical analysis was performed using the one-way ANOVA test at 5% significance level. The radiopacity and flow test results comply with ANSI/ADA norms. The values for setting time, solubility and dimensional stability did not meet the standards demanded by ADA Specification 57. Conclusion: The addition of iodoform to the Sealer 26® endodontic filler cement did not alter the property for radiopacity. However, it decreases the solubility and increases the values for setting time, flow, and dimensional stability.
