ENDO TRIBUNE | February 2010 Technology 3B Obturation system positions pack and flow side-by-side By Fred Michmershuizen, Online Editor The best equipment makes things easy for dentists. This is true for just about any type of system — including one for the obturation portion of endodontic treatment. The Calamus Dual 3D Obturation System, available from DENTSPLY Tulsa Dental Specialties, is designed to offer the best of both worlds in downpack and backfill obturation techniques. The Calamus Dual 3D positions the handpieces on one convenient, space-saving console. “With the Pack and Flow positioned side-by-side, dentists can move smoothly from one step to the next,” says DENTSPLY Tulsa. “Use the Pack to create an effective and cha or successfully placing an apical plug,” according to the company.

More appropriately, it is essential the clinician spend time with small hand K files to negotiable the canal from orifice to apex and take the initial canal size from a #6 to #15 before using RNT files. In this clinical case, two canals were located and a #6 precurved hand K file inserted until a tangible pop was felt at the minor constriction of the apical foramen (MC). The electronic apex locator was then used to take a true working length (TWL), a length that was confirmed when the first RNT file was taken to the apex and after the final RNT file was taken to the apex. The RNT system used in this clinical case was the Twisted File* (SybronEndo, Orange, CA, USA). The cutting flutes of TF are manufactured by twisting a piece of nickel titanium in the Rhomohedral crystalline phase configuration. As a result of its manufacture and triangular cross section, TF can easily create .08 tapers in a root such as #13. This taper is larger than the taper commonly prepared using RNT files that are manufactured by a grinding process. Twisting nickel titanium in R Phase and a triangular cross sectional design provides a flexible and highly efficient cutting instrument. In this clinical case, the .08 was able to reach the apex in approximately 4 insertions. After the .08/25 TF reached the apex, the .06/30/35 and .04/40 TF were taken to the apex of the two canals in one insertion of each TF size. The .06 and .04 tapers of the TF files easily reached the apex of the root as they cut dentin only on their tips. The tooth was obturated with RealSeal* bonded obturation with the SystemB technique utilizing the Elements Obturation Unit.* A .06/20 master cone was utilized. 3 mm back from the tip of a .06/20 master cone, the master cone is approximately .38 mm. 3 mm were trimmed from a .06/20 master cone and tug back was achieved.
