Description
Return observable photo area and unobserved eligible-area share.
Oral-health records may contain surface identifiers, annotation support, inventory or image calibration. Local count and balance rules do not verify observations, define an appropriate hygiene practice or establish a dental diagnosis.
Return observable photo area and unobserved eligible-area share.
When to use this tool
Use Oral Photo Unobserved Area Share when checking the stated oral-health record or measurement convention.
How to use the tool and how it works
- Enter totalAnnotatedArea, unobservedArea, excludedArea, overlap. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read observableArea, unobservedShare. Use the output convention below.
Return observable photo area and unobserved eligible-area share. Require consistent nonnegative area/overlap budgets and positive totalAnnotatedArea-excludedArea; observableArea = total-unobserved-excluded+overlap and unobservedShare = (unobserved-overlap)/(total-excluded).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| totalAnnotatedArea | Total Annotated Area | Required. Finite number. |
| unobservedArea | Unobserved Area | Required. Finite number; minimum 0. |
| excludedArea | Excluded Area | Required. Finite number; minimum 0. |
| overlap | Overlap | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| observableArea | Observable Area | Required. Finite number. |
| unobservedShare | Unobserved Share Unit: 1. | Required. Finite number. |

}Limitations and assumptions
- This is area accounting from supplied annotations, not an assessment of clinical image sufficiency.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use the relevant charting protocol and professional dental guidance for clinical interpretation, care and individual recommendations.
