Obturation guarantees the three-dimensional sealing of canals and conditions the success of the endodontic treatment in the long term. The HEROfill system is a 3rd generation endodontic obturator which was developed to allow the practitioner a fast and reliable means of obturating a root canal. The HEROfill kit is composed of verifiers to control the shaping and define the working length, obturators based on the principle of a solid biocompatible plastic core coated with thermoplastic Gutta Percha and an oven.
