Many characteristics such as adhesion to the tooth structure, long working time, ease of manipulation and good sealing ability of epoxy resin-based sealers made them the most commonly used sealers.10 A mixture of epoxy resins, amines, calcium phosphate, zirconium oxide, ethylene glycol salicylate, bismuth sub-carbonate and calcium oxide is incorporated into the recently introduced epoxy resin-based root canal sealer, Adseal.11 There are very few reports in the literature about its physical properties except for the reported radiopacity value.10
