Neoendo S rotary file is designed to have a special S-shaped cross-section. This allows minimum radial wall contact which translates to reduced stress on the file. In addition, the excellent upward debris auguring ensures that the debris isn’t pushed apically or packed into the apical third. Further, proprietary heat treatment ensures that the file remains highly flexible and resistant to fracture.

Cross-section- The cross-section of files is like the alphabet “S”

Sharp Cutting Edge- The two-blade cutting surface increases the cutting efficiency

Flexible NiTi Wire- Proprietary heat-treated NiTi wire with high fracture resistance

Progressive Pitch- Progressively increasing pitch avoids the screw-in effect

Safety Tip- Non-cutting safety tip helps to reduce ledge formation, minimize canal transportation & reduce apical extrusion

Length Marking- Helps to control the working length during preparation

Tip Size Indicator- The colored ring indicates the tip of the instrument

Taper Indicator- One ring-0.04 Taper | Two Rings- 0.06 Taper


  • Lengths: 21mm, 25mm

Usage Protocol

  • Prepare the access cavity and explore the canal using #8, #10 K-file or #12 Neoprobe File
  • Establish the working length with the help of Electronic Apex Locator(EAL)/ Radiograph
  • For obliterated, calcified, or severely curved canals: start with #8, #10 K-File or use Neoendo Flex Glide Files till apex to achieve proper glide path
  • Use the file in brushing motion: take the file passively to the point of least resistance and brush out of the canal and repeat the procedure until the working length is achieved
  • Always clean the cutting flutes after every few strokes, irrigate the canal and recapitulate with the K-File
  • Use Neoendo S files with a gentle touch, never force the file and always use the recommended speed and torque settings
  • Recommended Speed- 400 RPM, Torque- 2 NCm
