Dentsply ProTaper Universal NiTi Hand Files - Variable Taper 19mm Shaping X (SX)

Dentsply ProTaper Universal NiTi Hand Files are meticulously engineered endodontic instruments designed for efficient root canal preparation. These hand files leverage advanced Nickel Titanium (NiTi) technology, providing dental professionals with exceptional flexibility and resistance for navigating and shaping canals effectively.

The files feature a variable taper design and a convex, triangular cross-section, which enhances cutting action while reducing rotational friction between the file blade and dentin. The "Shaping X (SX)" file, with its 19mm length, is specifically utilized for creating additional coronal shaping and flare, particularly in coronally compromised or anatomically shorter teeth. A non-cutting, modified guiding tip allows the instrument to safely follow the secured portion of the canal, minimizing the risk of gouging.

Key Features : 

Constructed from Nickel-Titanium (NiTi) alloy for flexibility and durability in root canal shaping.
Designed for hand motion, offering tactile control for shaping fine and curved root canals.
Optimized for clinical use in shaping and cleaning the root canal system, with the "Shaping X (SX)" file specifically for coronal shaping.

Fill the pulp chamber with either Glyde or Sodium Hypochlorite (NaOCl) for all initial negotiation procedures.
Explore the coronal two-thirds of the canal with stainless steel Nos. 10 and 15 hand files using a reciprocating back-and-forth motion. Work these instruments passively and progressively until they are loose.
Start the ProTaper sequence with S1. The apical extent of S1 will passively follow the portion of the canal prepared with hand files.
S1 is designed to cut dentin in a crown-down manner with larger, stronger, and more active blades.
Irrigate, recapitulate with a size 10 hand file to break up debris, and re-irrigate.
Use a manual ProTaper handle motion by gently rotating clockwise until the file is snug and the flutes lightly engage dentin.
Cut dentin by rotating clockwise while simultaneously withdrawing the file.
If the file becomes over-engaged, disengage by rotating counterclockwise 45–90 degrees while withdrawing the instrument.
Repeat these motions until the desired length is achieved; one or more passes may be required depending on canal length, curvature, and diameter.
In difficult canals, repeat S1 as needed to pre-enlarge the coronal two-thirds of the canal.
Clean the blades frequently and continue using the file until it reaches the depth of the size 15 hand file.
Irrigate, recapitulate, and re-irrigate.
Use a pre-curved size 10 hand file in the presence of NaOCl or Glyde to negotiate the remaining canal and establish patency.
Determine the working length using a size 15 hand file.
Once a smooth glide path is verified, sequentially carry S1 followed by S2 to full working length.
Irrigate, recapitulate, and re-irrigate after each ProTaper instrument.
With the canal flooded with irrigant, work the F1 file to working length in one or more passes.
If the file stops advancing, remove it, clean the blades, and continue until working length is reached.
Irrigate, recapitulate, and re-irrigate.
Gauge the foramen with the corresponding hand file after using F1 to length.
If the file is snug at working length, the canal is shaped and ready for obturation.
If the file is loose, proceed to the next finishing file and gauge again until an appropriate apical fit is achieved.
