They are extremely flexible, universal, and safe. Their resistance to bending is around 10 times greater than the resistance of stainless steel instruments. NiTi S-files are recommended for the treatment of curved root canals, which can't be treated with stainless steel instruments. There is no need to pre-bend Endostar NiTi S-files. They are very efficient in root canal instrumentation and have a great cutting ability.
Precisely cutted shape
Made of nickel-titanium alloy with memory shape
Great cutting ability
2 cutting edges angled 90° (edges distributed symmetrically at 180° on the long axis),
Great dentin debris transportation
Excellent flexibility ensured by nickel-titanium alloy
Non-cutting tip
Millimeter scale etched on the blade (18 to 25mm from the tip), which facilitates the determination of the working length,
