Product Description T 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
