• Extended Reach: 31 mm length allows for deep apical preparation in long-rooted clinical cases.

• Exceptional Fracture Resistance: Specialized "hard-fiber" stainless steel treatment ensures the file can withstand high stress during shaping.

• Efficient Debris Removal: The twisted square cross-section effectively lifts dentin shavings out of the canal, preventing blockages.

• ISO Color-Coded Handles: Large, ergonomic handles are color-coded for quick identification (#45-White, #50-Yellow, #60-Red, #70-Blue, #80-Black).

The MANI® K-File is a high-precision endodontic hand instrument manufactured in Japan. These large-sized files (#45–80) are designed for the final enlargement and smoothing of the root canal system. This 31 mm extra-long version provides maximum reach, making it indispensable for treating teeth with exceptionally long roots while maintaining the structural rigidity required for larger canal diameters.

• Quantity: 6 pieces per box (Assorted sizes #45–80).

• Casing: Transparent polycarbonate sliding cassette.

• Compliance: Certified for clinical use with CE 0197 marking.

1. Technique: Utilize a "watch-winding" motion (alternating 90-degree clockwise and counter-clockwise turns) to advance and scout.

2. Shaping: Use a vertical filing motion against the canal walls to widen the space once the apex is reached.

3. Preparation: Must be thoroughly cleaned and autoclaved before the first clinical use and between patient appointments.

Before every insertion, check for signs of "unwinding," metal fatigue, or rust. Discard the file immediately if any deformity is observed.
