Clinician should choose a path of treatment that will result in best possible cleaning & shaping of the root canal system, coupled with an obturation technique that will provide a 3-D seal, apically, laterally, and coronally within the confines of the root canal system. We have progressed in endodontic obturation to realize that the sealer is the key to obtaining a true fluid tight seal.The challenge, more specifically, has been to find a sealer that would simultaneously bond to the canal wall as well as to the gutta-percha cone or a similar core material. Endodontic science has realized that if it could satisfy such a challenge, we would then have the possibility of creating a true monobloc. Root canal filling materials and techniques have advanced dramatically in the last two decades. Traditionally, gutta percha point combined with sealer has been the obturation of choice. Gutta percha is versatile, with a long history of use, but the drawback of gutta percha is it does not bond to root canal.
