K-File Size Progression Lookup
Bounded offline reference: ISO-style nominal hand-file tip sizes are hundredths of a millimeter; size is not an automatically recommended progression. Source: Endodontic instrument nominal ISO size convention. Actual instrument manufacturer, standard edition, taper and clinical selection must be verified. Explicit topic keys: 06, 08, 10, 15, 20, 25, 30, 35, 40. Not a full/current corpus, diagnosis, treatment recommendation or safety certification.
Description
Nominal endodontic file size identifies a tip diameter in hundredths of a millimeter.
Nominal endodontic file size identifies a tip diameter in hundredths of a millimeter.1
Actual instrument specifications still govern taper, length and manufacturing tolerances. Use this tool to select a short stored reference note.
When to use K-File Size Progression Lookup
Use this tool to select a short stored reference note. Establish the qualified examination or measurement context, matching instrument/protocol edition, site order and units.
How to use K-File Size Progression Lookup and understand its results
- Establish the qualified examination or measurement context, matching instrument/protocol edition, site order and units.
- Enter topic, using the field meanings and rules below, then run the tool.
- Read result.text. Interpret each field using the units, signs and evidence rules below.
- If input validation fails, correct the reported field and run again. Before applying a successful result, check the stated reference scope, units, assumptions and any retained unknown evidence.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| topic | Topic | string | Required |
Choose one of the exact, case-sensitive topic tokens listed below and run the tool. The implementation selects the corresponding stored text from a fixed object and returns it as result.text. Unknown tokens fail rather than fall back. The strings are shipped with the committed implementation: no search, generated forecast, external-corpus retrieval or live update occurs. The table preserves the actual stored wording.
| Exact topic token | Actual stored response |
|---|---|
| 10 | Nominal0.10mm tip. |
| 15 | Nominal0.15mm tip. |
| 20 | Nominal0.20mm tip. |
| 25 | Nominal0.25mm tip. |
| 30 | Nominal0.30mm tip. |
| 35 | Nominal0.35mm tip. |
| 40 | Nominal0.40mm tip. |
| 06 | Nominal0.06mm tip; verify actual instrument specification. |
| 08 | Nominal0.08mm tip. |
result.text=storedTopics[exact topic token] Apply the field units and exact ordering, boundary and evidence rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result containing the calculation or selected reference fields below | object |
| result.text | Stored reference text selected by the exact topic token | string |
{
"input": {
"topic": "06"
},
"output": {
"result": {
"text": "Nominal0.06mm tip; verify actual instrument specification."
}
}
}Limitations and assumptions
Coverage is limited to the topic table above. Stored wording may be abbreviated and does not provide a complete external corpus, report, benchmark inventory or updated forecast.
Every listed input requires an explicit value. Unexpected fields, incorrect value types, nonfinite numbers and sparse numeric arrays fail validation; tool-specific bounds and alignment rules apply as described above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful calculation that reports a false comparison or retains unknown evidence.
Alternative or Complementary methods
Use Taper Selection Lookup to examine a related aspect: Endodontic taper selection depends on anatomy, preparation objectives and instrument specifications.
Use Gutta-Percha Taper Fit Checker where its separate inputs and scope apply: Cone and prepared-canal diameter comparisons require matched positions.
