Abstract: The current concept of endodontic treatment is that after complete mechano-chemical debridement, a three-dimensional obturation must (should) be done. This becomes a key factor of successful endodontic therapy. It has been reported that a complete seal of the root canal system is possible only with the currently accepted materials and obturation techniques using a combination of gutta-percha and root canal sealer. Ideally, the root canal sealer should be capable of producing a bond between the core material and the dentine of the root canal. It should also be non-toxic and, preferably, have a positive effect on the healing processes of periapical destruction zone. Endodontic sealers based on zinc oxide and eugenols have been used clinically for several decades because of their satisfactory physicochemical properties. Ideally, contemporary root canal sealer should be penetrate into the dentinal tubules, bind to both organic and inorganic phases of dentin, neutralize microorganisms and their products, predictably induce a mineralized tissues - cementum and bone in regenerativehealing processes.
