The selection of appropriate obturating material is crucial in successful endodontic therapy. Proper root canal filling technique along with obturating material and sealer will ensure a complete seal of the root canal. Currently, Gutta-percha with a unique property of inertness, better sealing ability and the ability to do retreatment in case of failure, makes it an indispensable obturating material. Recent advances in alternative root filling materials also promises better adhesion to root canal and avert the short comings of gutta-percha.
