NT Rainbow S file are advanced heat treated rotary files used for effective and efficient root canal preparation. Its Manufactured from premium quality nickel-titanium alloy. Specific heat treatment and surface treatment results in high flexibility and durability at the same time.

CHARACTERISTIC FEATURES
* NT Rainbow S file are manufactured by Innovative heat-treatment Technology and subsequent surface therapy. This results in reduced crack propagation tendency thus improving resistance to cyclic fatigue.

* It has Upgraded slim S-shaped cross section. This results in very high flexibility . The files can easily negotiate and prepare curved root canals.The innovative design results in transportation of debris up the canal and decreases preparation time.

* It has inactive tip design that allows safe preparation, minimizing the risk of perforations and zipping.

* Variable pitch design over the length results in better mechanical resistance, and reduce the risk of tip fracture.

* NT Rainbow S Files if bent ,do not get back to initial straight shape at room temperature. Due to this property these files can be pre-curved, before inserting into the root canal.

* Each file is taper value marked on the handle for easy identification
