Clinical Usage Instructions (IFU)

Step 1: Negotiate to working length (WL) using an ISO 10 K-file.
Step 2: Use 01/09 (19mm) to create the coronal 1/3 orifice opening only.
Step 3: Select the initial file according to canal width: narrow canals → #20/04, moderate canals → #25/04, wide canals → #30/04.
Step 4: Prepare to WL sequentially from the selected starting size upward (e.g., #20/04 → #25/04 → #30/04 → #35/04).
Step 5: Use #25/06 as the finishing file (if a larger taper is desired).

Gold (Pro-Flexi Gold) vs. Blue (Pro-Flexi Blue)

Gold: Heat-activated treatment, superior flexibility → ideal for curved canals
Blue: Heat-activated treatment, stronger cutting force → ideal for straight canals and infected canals

Both share identical size specifications. The choice depends on clinical preference.
