Debris Index Calculator
Actual Greene–Vermilliondebris index, actual protocol-defined scored sites mean of known ordinalcodes0–3. Actual instrument version, surface selection and clinician scoring independently verified; partial mean explicitly not complete-mouth index or diagnosis.
Description
A debris index summarizes independently coded deposits at examination sites.
A debris index summarizes independently coded deposits at examination sites.1
A known-site mean describes the included observations rather than all possible sites. Use this tool to calculate the stated observation or conditional model from supplied measurements.
When to use Debris Index Calculator
Use this tool to calculate the stated observation or conditional model from supplied measurements. Establish the qualified examination or measurement context, matching instrument/protocol edition, site order and units.
How to use Debris Index Calculator and understand its results
- Establish the qualified examination or measurement context, matching instrument/protocol edition, site order and units.
- Enter independentlyCodedSiteScores, siteEvidenceKnownFlags, using the field meanings and rules below, then run the tool.
- Read result.observedKnownSiteMeanScore, result.knownSiteCount, result.unknownSiteIndices. 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 |
|---|---|---|---|
| independentlyCodedSiteScores | Independently coded site scores | list of number | Required |
| siteEvidenceKnownFlags | Site evidence known flags; 1 means known and 0 means unknown; keep the same item order | list of number | Required |
Supply nonempty aligned site-score and binary known-flag lists. Every score, including unknown placeholders, must be an integer from 0 through 3. Select scores with known=1; require at least one known site, compute its arithmetic mean, report the known count and retain zero-based unknown indices. This calculates the submitted known-site summary without choosing sites or diagnosing severity.
meanKnownScore=Σ_known(score_i)/knownCount; unknownIndices={i:known_i=0} 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.observedKnownSiteMeanScore | Arithmetic mean of the known submitted site codes | number |
| result.knownSiteCount | Number of site observations with known flag 1 | number |
| result.unknownSiteIndices | Zero-based positions of unknown site observations | list of values |

}Limitations and assumptions
A known-site mean describes the included observations rather than all possible sites. Results depend on the independently established measurement basis and the exact model assumptions above.
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.
