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. Expanding on the principle of a solid plastic core coated with thermoplastic gutta percha, the enhancements found in the HEROfill® system add accuracy and dependability to the well documented apical seal that may be obtained with endodontic obturators.
