API Protaper Hand Files 25mm

API Protaper Hand Files 25mm

API Protaper Hand Files are designed with advanced file geometry and flexible NiTi construction to support efficient and controlled root canal preparation. Their sharp cutting edges, progressive pitch, and safety tip design contribute to effective shaping while maintaining canal integrity.

The S-shaped cross-section minimizes radial wall contact, reducing stress on the file. Excellent upward debris auguring helps prevent apical packing, while proprietary heat-treated NiTi ensures high flexibility and resistance to fracture.

Features

• S-shaped cross-section
• Sharp cutting edges
• Flexible NiTi wire
• Progressive pitch design
• Non-cutting safety tip
• Length markings
• Tip size indicator

Description

• S-shaped cross-section reduces radial wall contact and file stress
• Two-blade cutting surface increases cutting efficiency
• Heat-treated NiTi wire provides high flexibility and fracture resistance
• Progressively increasing pitch helps avoid the screw-in effect
• Non-cutting safety tip reduces ledge formation, canal transportation, and apical extrusion
• Length markings assist in controlling working length during preparation
• Colored ring indicates the instrument tip size
• Taper indicator: One ring – 0.04 taper | Two rings – 0.06 taper

Directions to Use

• Prepare the access cavity and explore the canal using #8, #10 K-file, or #12 probe file
• Establish the working length using an electronic apex locator (EAL) or radiograph
• For obliterated, calcified, or severely curved canals, create a glide path using small K-files or glide path files
• Use the file in a brushing motion, advancing passively to the point of least resistance
• Clean the cutting flutes frequently, irrigate the canal, and recapitulate with a K-file
• Use files with a gentle touch, never force them, and always follow recommended speed and torque settings
