Dental Endo Niti Files

CICADA Medical’s endodontic hand files with large handles are supreme in China. The material used for NiTi files differs from that used for K-files, whereas the file form is the same on both.

NiTi files and K-files utilize different materials but share the same basic file format. Nickel-titanium, or NiTi, is a flexible material that can be bent or deformed without permanently altering its shape. Given that the tip of the instrument is not used for cutting, CICADA Medical NiTi tools are particularly well-suited for the preparation of curved canals. These tools can be used with a file action or a rotating preparation motion.

Since root canals vary in morphology and path, every root canal preparation must be tailored to the specific tooth being worked on. Root canals prepared with a handpiece using the crown-down method require a specific system, and the NT-Endo system was designed to meet those needs. The nickel-titanium instruments have specially designed blade geometry that ensures a smooth, conical root canal preparation.

Even on challenging canal paths, canal perforations are not permissible. Instruments with a conicity of 6% are used to shape the conical-radicular area, while instruments with a conicity of 4% are used to shape the apex. Additionally, this type of consistent, conical root canal preparation simplifies the fitting and modification of gutta percha points.

Dental Endo Niti Files, also known as Endodontic Nickel-Titanium Rotary Files, are a crucial part of modern endodontic treatment. These files are used to clean and shape root canals, removing the infected pulp tissue and preparing the canal for filling. The unique property of these files is their ability to bend and adapt to the shape of the canal and then return to their original shape. This is due to the superelastic property of the Nickel-Titanium (NiTi) alloy from which they are made. This flexibility and resilience make them a preferred choice for endodontic procedures, especially in curved or complex root canal systems.

Advantages of Dental Endo Niti Files

NiTi files have several advantages over traditional stainless steel files. Firstly, their superior flexibility allows them to negotiate curved canals with less risk of ledging, zipping, or perforating the canal walls. This results in a smoother and more predictable canal shape. Secondly, NiTi files have a high resistance to cyclic fatigue, which is the stress and strain a file undergoes during a procedure. This reduces the risk of file separation within the canal, a complication that can be challenging to manage. Lastly, NiTi files have a cutting efficiency that allows for faster and more efficient removal of infected pulp tissue.

Types of Dental Endo Niti Files

There are various types of Dental Endo Niti Files available in the market, each designed to cater to specific needs during endodontic procedures. Some of the popular ones include:

Helix Files – NiTi Rotary Files

Helix Files are known for their excellent flexibility, which allows them to adapt to the complex anatomy of root canals. They are available in standard ISO sizes, with 0.04 and 0.06 taper, allowing for a range of canal shapes and sizes.

K3XF Greater Taper Technique

The K3XF Greater Taper System offers a complete shaping and filling technique. These files are available in new sizes color-coded with matching gutta-percha points and paper points for convenience. The system is designed to provide efficient and predictable results.

ProFile Orifice Opener Rotary Files

ProFile Orifice Opener Rotary Files are designed to efficiently prepare the coronal portion of the canal. They can be used in place of a Gates Glidden drill, reducing the number of instruments needed. They are made from a NiTi alloy, providing the flexibility and cutting efficiency that is characteristic of NiTi files.

Dental Endo Niti Files vs Stainless Steel

NiTi files have been found to cause significantly less canal transportation, which is the deviation of the canal shape from its original path. They also remove less volume of dentin, preserving more tooth structure. In addition, NiTi files require less instrumentation time, making the procedure more efficient. They also produce more centered and rounder canal preparations than K-flex stainless steel files used in a quarter turn/pull technique. This results in a more predictable and efficient filling of the canal.

Dental Endo Niti Files in China

In China, all endo files are mandated by law to be single-patient use. This means that each file is used for one patient and then discarded. This practice significantly reduces the risk of file separation (fracture) as the files do not undergo the stress of multiple uses. Outside of China, files may be used multiple times, so separation due to work-hardening is a more significant problem.

Glide Path Size for Dental Endo Niti Files

The glide path is the initial path created in the canal before the use of rotary files. It is recommended that the Glide Path should be size 20, to prevent separation of the files. If using Hand Files only, and single-use files, the Glide Path should be prepared to a loose size 15. This ensures that the rotary files can follow the path without undue stress, reducing the risk of file separation.

CICADA Medical’s Recommendation on Dental Endo Niti Files

CICADA Medical, a leading provider of dental products, recommends that if using PathFiles, practitioners should go up to size 19 (P3). These files are flexible enough to go round the curves nicely, without causing transportation or ledging. This recommendation is based on extensive research and experience in the field of endodontics.


Dental Endo Niti Files have revolutionized endodontic treatment, offering superior flexibility and cutting efficiency. They are a crucial tool in the arsenal of every endodontist and dentist performing root canal treatments. With the right selection and use, these files can significantly improve the outcomes of endodontic treatment, leading to better patient satisfaction and oral health.

For endodontic instruments, the practical advantages of this principle are evident: a NiTi file with “controlled memory” adapts to the anatomical shape of the root canal during the entire treatment procedure. In case of resistance or a block in the canal, the file bypasses this stress situation by changing their cross-sectional shape.

Nowhere in dentistry is technical progress as rapid as in modern endodontics. The development of flexible nickel-titanium files in the late 1980s created entirely new and hitherto unknown opportunities in the mechanical preparation of root canals.

Classical NiTi files are milled on CNC machines. Electrical Discharge Machining (EDM) uses spark erosion, which hardens the surface of the NiTi file, resulting in superior fracture resistance and improved cutting efficiency. Repeated bombardment of the alloy with sparks melts the material and even leads to evaporation in some places.
