This worked review is a composite assembled from findings that repeat across dental practices, not a report on a named clinic. The figures illustrate the pattern rather than describing one practice, and the value is in the sequence of fixes rather than the numbers.
The finding was familiar: monitoring was being run, but the log could not demonstrate it. The sterilizer worked, indicators were purchased, and nothing in the record explained who had run the test or what the result had been.
What the auditor found
Three gaps. First, the monitoring log showed a result for some days and nothing for others, with no explanation for the blank days. Second, the log recorded "passed" without the indicator lot number or the incubator used, so a result could not be traced to a batch. Third, on days when the sterilizer was not used, the sheet was left blank rather than marked as a no-use day, which made genuine gaps indistinguishable from missed tests.
The practice's position was that testing was being done. The record could not support that position, and in an audit the record is the position.
What the practice did first
It stopped, and wrote down the current routine before changing anything. Three questions had to be answered in writing: on which days is the sterilizer used, who runs the biological indicator, and where is the result recorded. Writing those answers exposed the actual problem, which was that the task had no named owner and depended on whoever had time.
How the log was rebuilt
Four fields were added to the existing sheet, and the sheet was pre-printed with one row per working day so a blank row was visible as an anomaly:
| Field | Why it was added |
|---|---|
| Named operator | Establishes who ran the test and who to ask when a result is unclear |
| Indicator lot number | Lets a result be traced to a batch if a lot issue emerges |
| Incubator and control result | Shows the test had a valid control and correct incubation |
| No-use day marking | Distinguishes a day with no sterilizer use from a missed test |
The final structure was simple: one line per day, signed by the operator, reviewed weekly by the practice lead. Total time to complete, two minutes a day.
What changed in the routine
Three things. The monitoring task was assigned to a named lead with a named backup, so leave no longer broke the sequence. The indicators and controls were stored together with the incubator, so the batch could not be started without the control. And the weekly review was diarised rather than left to memory, which is what turned a daily habit into a documented one.
Our guide to the RCDSO answer on spore testing frequency covers the daily expectation that the log has to reflect, and the parallel worked review on rebuilding records after an air-removal failure shows the same reconstruction method applied to a different finding.
What the practice learned about the indicators themselves
Two operational points came out of the rebuild. Storing indicators next to the incubator removed a daily walk and cut the number of late batch starts. Keeping the control tube with the test tube meant the control could not be forgotten. Our note on what a sterilizer repair exposed in a spore test log covers the related case where a maintenance event revealed a monitoring gap.
The consumables that made the rebuilt routine work were a single standard indicator format and a dedicated incubator: 24-hour readout biological indicators for the daily record and a 24-well dry block incubator to hold the batch.
A practice rebuilding a log from scratch can start with a trial quantity and a blank log template rather than a full case: the BI 5-pack trial (CA $12.99) covers a first batch with controls, and the dental compliance hub collects the related records guidance.

Frequently Asked Questions
Do blank days in a monitoring log look worse than a recorded failure?
Yes. A recorded failure with a corrective action shows the process working; a blank day shows nothing at all, and an auditor cannot tell a missed test from a forgotten record.
Does the log need the indicator lot number if the results are all negative?
It does. Lot tracing matters most when a manufacturing issue is reported later, and at that point the log is the only way to know which batches are affected.
Who should review the log?
The practice lead or clinical owner, weekly. A review signature is what distinguishes a monitored process from a record filled in afterwards.
How should a practice handle a genuine gap in testing?
Record the gap, the reason, and how any affected packs were reprocessed. A documented gap is manageable; a concealed one is a credibility problem.
