Does it matter if I use an obturator or master cone for obturation?
There is abundant evidence in the endodontic literature, using Thermafil (Dentsply Tulsa Dental, Tulsa, OK) as an example, to prove that carrier-based obturation provides a clinically acceptable obturation relative to other noncarrier-based delivery systems. Both materials have their clinical application. I use both RealSeal One Bonded Obturators* (warm carrier-based bonded obturation product) and RealSeal* master cones based on personal preference in any given clinical case. Both of these materials create a bonded obturation that provides resistance to coronal leakage relative to gutta percha. RealSeal One Bonded Obturators* possess several features not shared by other warm carrier-based devices: they are dissolvable in chloroform, they can be shredded with the .08/25 Twisted File* at 900 RPM, and they create a bonded obturation with the aforementioned benefits. In essence, with chloroform and the Twisted File, RealSeal One Bonded Obturators can be easily removed from the canal. What
