MANI K-Files 21mm are precision endodontic hand instruments used by dentists and endodontists for root canal treatments. The "21mm" refers to the working length of the file, making them ideal for treating teeth with limited mouth opening (like second molars) or where standard 25mm files are too long and unwieldy.

Key Features

• Functionality: Used for canal scouting, establishing a glide path, shaping the root canal, and removing debris.
• Material: Manufactured from MANI’s proprietary 18-8 hard-fiber stainless steel, ensuring durability, sharpness, and resistance to corrosion even after repeated autoclaving.
• Design: They feature a twisted, rigid design with safe-ended tips that help prevent the perforation of the canal.
• Handling: Color-coded ISO silicone handles allow for rapid visual size identification, while the polybutylene terephthalate (PBT) shank remains dimensionally stable during sterilization.

Specification

Each K-File measures 21mm in length and is crafted from stainless steel for enhanced strength and flexibility. These files comply with international dental standards, ensuring safety and efficacy in clinical applications. They are available in various sizes to accommodate different clinical needs.

They come in a standardized range of ISO sizes (typically from very fine #06 up to #140), and are usually sold in blister packs of 6 files

Usage

K-Files are used during root canal treatments to clean and shape the canal space. It is recommended to handle them with care to maintain their integrity and effectiveness. Store in a dry place away from direct sunlight to prolong their lifespan.

Unlike rotary files, K-Files are manual hand instruments. They are typically operated using a "watch-winding" motion (a gentle quarter-turn back and forth) combined with a vertical filing or reaming pull stroke.
