Glide path development is an essential but time-consuming step in endodontic treatment. To increase endodontic efficiency in the initial glide path formation by simplifying the procedure while increasing safety, MICRO-MEGA^® is introducing two new rotary NiTi instruments, the G-Files™. The G-File™ instruments are based on an innovative design to help the clinician safely save time in endodontic procedures. The superior cross-section of the G-Files™ combines efficiency and innovation. The G-File™ NiTi instruments are machined with a narrow diameter (12 and 17) with a slight .03 taper. The superior cross-section of the G-File™ combines efficiency and safety. Along the length of the instrument, the G-File™ has cutting edges on three different radiuses, creating a large and efficient area for upward debris removal.

The angular offset of the cutting edges also creates a different pitch along the length of the blade, avoiding any screwing or engaging effect into the walls of the canal. The non-working (safety) tip is asymmetrical which helps the instrument safely move forward; this is also facilitated by the high degree of flexibility resulting from the small diameter.
The G-Files™ are electro-polished, which improves their mechanical properties, particularly by releasing internal stresses which develop during machining, thereby increasing the flexibility of the G-File™. The electro-polished surface increases the efficiency in apical progression of the G-File™ while aiding in debris removal. The G-Files™ are available in 21, 25 and 29 mm.

Used after hand files have measured working length, G-Files™ safely enlarge the glide path in preparation for RCT with rotary instrumentation system.
