How to Use This Calculator
- Enter the Initial Apical File size (ISO) that binds at the apex.
- Set Target Apical Size (ISO) for the final apical preparation.
- Input Canal Curvature (degrees) and Working Length (mm).
- Review Number of Files in the sequence, Recommended Taper, and Coronal Flare Size.
- Use the sequence to select the correct rotary or reciprocating file series for the case.
How the result changes with Initial apical file (ISO)
| Initial apical file (ISO) | Files in sequence |
|---|---|
| 9.4 | 5 |
| 18 | 3 |
| 28 | 1 |
| 37 | 1 |
What each input means
- Initial apical file (ISO)
- First file that binds at working length (ISO size).
- Target apical size (ISO)
- Desired final apical preparation size.
- Canal curvature (degrees)
- Maximum curvature angle of the canal.
- Working length (mm)
- Established working length in millimeters.
What each result means
- Files in sequence
- Total number of rotary files needed in the shaping sequence.
- Recommended taper
- Suggested file taper based on canal curvature.
- Coronal flare size (ISO)
- Recommended coronal flare file size.
- Est. instrumentation time (min)
- Estimated total instrumentation time per canal.
- File fracture risk (0-100)
- Relative fracture risk considering curvature, length, and size.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersInitial apical file (ISO) = 10, Target apical size (ISO) = 30, Canal curvature (degrees) = 20, Working length (mm) = 21 = 4 input(s) provided

- Calculate Recommended taper0.06 = 0.06
- Calculate Coronal flare sizeCoronal flare size45 = 45
