The role of endodontic treatment is to provide proper cleaning, shaping and obturation of the root canal system, all three processes are interlinked and dependent on one another. Endodontic sealers are materials which provide a three dimensional fluid- proof seal in the root canal system of a tooth, which provides a favourable environment for periapical healing as well as to prevent chances of re-infection. An ideal endodontic sealer has to possess certain characteristic properties essential for attaining the desired sealing of the root canal system such as high radiopacity, flowability, sealing, biocompatibility, low solubility, reliable working time and adhesion to canal walls. Currently sealers available in the market are zinc-oxide eugenol, calcium hydroxide containing, resin-based, glass-ionomer based, silicone-based, and bioceramic-based sealers.
