Endodontic files are labeled with a number and letter code that indicates their size, taper, and usage. Here's a breakdown of the coding system:
- Number: Represents the file's diameter at the tip, measured in hundredths of a millimeter (e.g., 06, 08, 10, etc.).
- Letter: Indicates the file's taper (e.g., K, H, R, etc.).
- ISO Color Code: A color-coded system that corresponds to the file's size and taper.
Common Endodontic File Sizes and Codes:
- 06 (0.06 mm diameter, K-file)
- 08 (0.08 mm diameter, K-file)
- 10 (0.10 mm diameter, K-file)
- 15 (0.15 mm diameter, H-file)
- 20 (0.20 mm diameter, H-file)
- 25 (0.25 mm diameter, R-file)
- 30 (0.30 mm diameter, R-file)
ISO Color Code:
- White (06, 08)
- Yellow (10, 15)
- Red (20, 25)
- Blue (30, 35)
Keep in mind that different manufacturers may have slightly varying codes, so it's essential to familiarize yourself with the specific coding system used by your preferred brand.
