G-File advantages:
- Flexibility due to their small diameters (n°12 and n°17)
- Slight taper (0.03)
- Safety and non-working tip
- Electro-polished surface
- Enhanced circulation of the irrigation solution
- Enlarge the canal passageway quickly and safely to the apex
- Useable in combination with the Revo-S™ system or any other NiTi system

G-File protocol:
- Determine the working length (WL) with a hand file (K-File #10 or 08)
- The rotating G1 instrument is introduced into the canal, progressing with a slow movement without any apical pressure until the working length has been reached
- After irrigation, the G2 instrument is used in the same way; then the last hand file is used again to check canal patency and confirm the working length.
