Product Details

Description:

The 47-510 PROTAPER U ROTARY S1 21MM (B) is a specialized rotary file made from nickel-titanium, designed as a key element of the ProTaper Universal endodontic system. Carefully crafted for shaping the coronal and mid-root thirds of the root canal, the S1 file lays an essential foundation for safe and effective canal preparation. With a working length of 21mm, this file is particularly designed for anterior teeth, premolars, or situations where anatomical challenges exist, such as shortened root canal lengths or limited access. This file boasts a progressive taper design and a convex triangular cross-section, allowing for enhanced cutting efficiency while reducing contact with canal walls. Such geometry enables the file to remove dentin in a controlled way, decreasing torsional stress and considerably minimizing the chance of instrument breakage. The gradual taper also aids in the seamless progression of subsequent shaping files, making canal enlargement safer and more predictable. Constructed from a highly flexible nickel-titanium alloy, the ProTaper S1 21mm can navigate curved or narrow canals while keeping central alignment. Its flexibility helps to retain the original canal structure, thus reducing the likelihood of procedural mistakes such as ledging or zipping. The 21mm length offers clinicians better control, visibility, and access—critical when treating pediatric patients or those with complex oral anatomy. The S1 file is crucial for eliminating coronal interferences and establishing a smooth glide path, which allows subsequent files to function with less resistance and increased efficiency. Its optimized flute design further enhances debris removal during rotation, keeping the canal system cleaner and promoting effective irrigation throughout the procedure. It operates optimally with standard endodontic motors set to manufacturer-specified torque and speed settings. The 47-510 PROTAPER U ROTARY S1 21MM (B) is essential for practitioners looking for dependable performance, enhanced control, and precision during the initial stage of root canal shaping. As a component of the respected ProTaper Universal sequence, it facilitates high-quality results in both standard and complicated endodontic procedures.
