Access Preparation
- Prepare a proper access cavity to gain straight-line entry to the canal.
File Selection
- Choose an appropriate ISO size (e.g., #06, #08, #10, or #15) based on canal size and difficulty.
Irrigation
- Irrigate the canal with sodium hypochlorite to soften debris and facilitate entry.
Initial Insertion
- Insert the file gently into the canal using a watch-winding or balanced force technique.
Negotiation
- Advance the file with controlled motion to negotiate the canal curvature or calcification.
Length Determination
- Use the calibration rings for visual reference; confirm working length with an apex locator or radiograph.
Debris Removal
- Withdraw the file periodically, clean it, and irrigate the canal to remove accumulated debris.
Repeat as Needed
- Repeat with increasing file sizes as the canal allows, ensuring minimal resistance and maintaining control.
Final Rinse & Inspection
- Perform a final irrigation and inspect the file for signs of distortion or wear before disposal.
