Description
nominalDepth = originDepth+index*thickness; correctedDepth adds missingBefore*thickness; lostDepth = missingBefore*thickness.
Dental specimen and bench-model measurements need an explicit image scale, coordinate origin and geometric convention. A linear taper, chord ratio or calibrated length describes a supplied model and does not establish anatomy or guide clinical treatment.
nominalDepth = originDepth+index*thickness; correctedDepth adds missingBefore*thickness; lostDepth = missingBefore*thickness.
When to use this tool
Use Root Model Section Thickness Offset when checking a supplied research or bench-model dimension.
How to use the tool and how it works
- Enter index, nominalThickness, missingBefore, originDepth. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read nominalDepth, correctedDepth, lostDepth. Use the output convention below.
Require nonnegative whole index and missingBefore and positive nominalThickness. nominalDepth = originDepth+index*thickness; correctedDepth adds missingBefore*thickness; lostDepth = missingBefore*thickness.1

| nominalThickness | Nominal Thickness | Required. Finite number; strictly above 0. |
| missingBefore | Missing Before | Required. Safe integer; minimum 0. |
| originDepth | Origin Depth | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| nominalDepth | Nominal Depth | Required. Finite number. |
| correctedDepth | Corrected Depth | Required. Finite number. |
| lostDepth | Lost Depth | Required. Finite number. |

}Limitations and assumptions
- Depths share one length unit. This assumes uniform sections and a supplied missing-section count, without reconstructing tissue loss or clinical working length.
- 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 verified specimen and instrument methods, full geometry and professional clinical assessment when the question extends beyond bench arithmetic.
