Dentsply ProTaper Next Assorted (X1-X3) NiTi Rotary Files - 21mm

This Pro Taper Next file system provides various shaping advantages through a variable tapered design on a given file, M-Wire technology and a unique offset mass of rotation. It is a versatile and flexible system capable of handling a majority of root canal treatments, including the complex cases. ProTaper Next Files has been the gold standard in endodontics for many years and has been an effective solution for practitioners. The ProTaper Next file system utilizes increasing and decreasing percentage tapered design on a single file. This aids in minimizing the contact between the file and dentin, which increases the efficiency while decreasing the dangerous taper lock and the screw effect. ProTaper NEXT Dentsply files have swaggering movement of the file and utilize the innovative M-Wire technology for strengthening NiTi.Unlike the concentric core in ProTaper Universal File system, ProTaper NEXT features an off-center rectangular core. This adds greater strength to the file as it tracks down the canal. Only two points of the rectangular cross section touch the canal wall at one time, as the axis of rotation differs from the center of mass. The M-Wire technology improves the resistance of the file to cyclic fatigue by almost 400%, when compared with other files having same tip diameter, taper and cross section. While increasing the flexibility of the file, the M-Wire technology decreases the potential for broken instruments. ProTaper NEXT files produce a unique asymmetrical rotary motion.

The advantages of the rotary motion and the fact that the file contacts the canal wall at only two points are:

•Reduced engagement due to the swaggering effect, limiting undesirable taper lock

•More cross-sectional space for enhanced cutting•Allows to cut a bigger envelope of motion Canal Shaping with ProTaper Next:

•While using NaOCl, follow the established guidepath with ProTaper Next X1 file till working length. •Use ProTaper Next X2 in the same manner •Gauge the size of the foramen using a #25 size hand file

•If the file binds at length, it indicates that the canal is shaped and ready for disinfection •If the file is loose at complete working length, continue shaping with X3 file and if necessary X4 and X5 files, gauging after each instrument change with #30, #40 or #50 hand files respectively.

Recommendations for use:

•Use the files in a constant rotation at 300 rpm speed with light apical pressure •Recommended torque control – 2.- Ncm, however it is adjustable upto 5.2Ncm based on the practitioner’s experience

•Clean the instrument flutes frequently and check for signs of wear or distortion

•In very severe curvatures use the files manually in a clockwise continuous motion

•It is recommended to use ProTaper Next files with a brushing motion away external root concavities, so as to facilitate flute uploading apical file progression.

•Use files passively the canal until the working length is reached. Package Contents: 1 x 6Files
