Super Endo blue rotary Files are thermally treated instruments leading to an improved version.
These files have increased resistance to cyclic fatigue and greater flexibility enabling a smoother and safer canal preparation.

These files are extremely flexible but without the shape memory of conventional NiTi files. This gives the file the ability to follow the anatomy of the canal very closely, reducing the risk of lodging, transportation, or perforation.
Furthermore, the files can be pre-bent, similar to the way of stainless steel. This form of adaptation can be reversed quickly by heat treatment ( during autoclaving or with a glass bead sterilizer) returning the instrument back to their original shape
These files provide a clear visual opportunity to verify the safe continuation of file use.

A nickel-titanium rotary file is an engine-driven tapered and pointed endodontic instrument made of nickel-titanium alloy with cutting edges
used to mechanically shape and prepare the root canals during endodontic therapy or to remove the root canal obturating material while performing retreatment.
Superelasticity and shape memory are the properties that make nickel-titanium rotary files very flexible.
The high flexibility makes them superior to stainless steel files for the purpose of rotary root canal preparation.
The use of nickel-titanium rotary files in dentistry is a common practice.
Super Endo blue rotary Files are indicated in the biomechanical preparation of the root canal during endodontic therapy.
