Description
Compare a recorded instrument-pack expiry with a planned-use date.
Dental records depend on surface notation, assessed and excluded denominators, missing versus observed zero, reporting quanta and recorded equipment dates. Calendar-day counts can be elapsed or inclusive, and nominal expiry comparisons do not establish sterility. Local surface fractions and source labels are not automatically validated clinical indices.
Compare a recorded instrument-pack expiry with a planned-use date.
When to use this tool
Use Dental Instrument Pack Expiry when you already have expiryDate, plannedUseDate and need to compare a recorded instrument-pack expiry with a planned-use date.
How to use the tool and how it works
- Enter expiryDate, plannedUseDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read expiredByDate, remainingDays. Inspect expiredByDate before interpreting the associated values.
Parse real UTC dates; remaining=expiry-plannedUse, expiredByDate=remaining<0.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| expiryDate | Expiry Date | Required. Text; maximum UTF-16 length 8192. Real proleptic Gregorian YYYY-MM-DD; four-digit years 0000-9999 accepted. |
| plannedUseDate | Planned Use Date | Required. Text; maximum UTF-16 length 8192. Real proleptic Gregorian YYYY-MM-DD; four-digit years 0000-9999 accepted. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| expiredByDate | True strictly after the printed expiry date; equality is not flagged expired. | Required. Boolean. |
| remainingDays | Remaining Days | Required. Safe integer. |

}Limitations and assumptions
- Expiry-date equality is not flagged expired. No sterility, package integrity, actual expiry policy, reprocessing quality or safe use is established.
- 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.
Alternative or Complementary methods
Use original chart, observation and reprocessing records with the complete scoring or controlled workflow. Keep denominator, missingness and date conventions explicit; local arithmetic does not determine oral-health status, appropriate recall intervals or readiness for care.
