DENTSPLY Tulsa Dental Specialties has developed the first obturator with a crosslinked gutta-percha core. The unique cross linking technology used to develop GuttaCore transforms gutta-percha making it the ideal core material for centrally condensing the warm flowable gutta-percha with a hydraulic force that sends it flowing throughout the entire canal system with one insertion. Before the development of GuttaCore, warm gutta-percha was deemed unsuitable for use as an obturator core because it melted when heated. Cross linking the gutta-percha connects the polymer chains and transforms the obturation material, keeping it from melting. This established scientific process subtly strengthens the gutta-percha while retaining its shape and its familiar benefits. GuttaCore simplifies post space creation and retreatment as it removes with unprecedented ease. The obturator handle removes by bending to either side of the canal wall without affecting its seal. Supported by extensive research, GuttaCore allows practitioners to achieve dense, 3-D fills in the most challenging root canal systems.
