Key takeaways
- Retain unresolved amounts in the full denominator.
- Distinguish a bound from a probability estimate.
- Show how new evidence narrows the range.
- Do not call a classification change business growth.
What does hygiene percentage divide?
Dentrix Enterprise's Production Summary Report supports category filters and reports a percent of charges. Production Summary measures. The selected category boundary therefore belongs beside the percentage.
Open Dental documents customizable procedure categories. Procedure categories. A familiar category name is not enough to establish that the practice's entire file has been mapped consistently.
This entry addresses incomplete classification. It does not establish a desired hygiene share or a clinical target. The hygiene valuation guide separately explains why even a well-supported share cannot determine earnings or value by itself.
Keep unresolved production in the denominator
Assume an invented completed-production file totals $200,000 for one period and one location. The full total has been checked. Every amount is nonnegative and belongs somewhere in that total; there are no duplicates, missing charges, adjustments or later corrections in this example.
The agreed classification currently identifies $40,000 as hygiene and $130,000 as other work. Another $30,000 is not yet classified. That unresolved amount could be hygiene, other work or a mix of both. Its classification changes neither the full total nor the amount already verified as hygiene.
| Classification at the review date | Amount | Share of the full $200,000 |
|---|---|---|
| Verified hygiene | $40,000 | 20% |
| Verified other work | $130,000 | 65% |
| Unresolved classification | $30,000 | 15% |
| All production in scope | $200,000 | 100% |
The verified hygiene amount supplies a lower boundary of 20%. If every unresolved dollar were hygiene, the amount would be $70,000 and its share would be 35%. Thus the file supports a range from 20% to 35%, subject to the stated assumptions. It does not support choosing a point within that range without more evidence.
This is an arithmetic bound, not a confidence interval or a forecast. It assigns no probability to either end. It also says nothing about appropriate care, collection prospects or the margin on those services.
Dropping the unresolved group would create a $170,000 denominator. Dividing $40,000 by that smaller amount gives about 23.53%. That is the share among currently classified production, not the share of the whole practice. If that narrower measure is useful, label it explicitly and keep the missing $30,000 visible.
Show how new classification evidence changes the range
First, assume records establish that $12,000 of the unresolved amount belongs in hygiene. Verified hygiene becomes $52,000 and unresolved production falls to $18,000. The lower boundary rises to 26%; the upper boundary remains 35%, because $52,000 + $18,000 still equals $70,000.
The range narrows from 15 percentage points to nine. No new service was performed and no receipt arrived. The change comes from better classification evidence. Do not describe it as hygiene growth in the sale narrative.
For a separate test, restore the original file. Now establish that $15,000 of the original unresolved amount is other work. Verified hygiene remains $40,000, while unresolved production falls to $15,000. The lower boundary stays 20%; the upper boundary falls to 27.5%. The range is now 7.5 percentage points wide.
These tests answer different evidence questions and should not be combined unless both findings apply. A genuine change to the full production total would require a new calculation. These bounds rely on the stated fixed total and nonnegative components; they are not a shortcut for unresolved credit balances or missing transactions.
Decide what must be resolved before using a point estimate
Ask which unresolved rows could materially affect the decision. Name the document needed, the person who can interpret it and the current status. Work from the original records, preserving the earlier classification rather than replacing it without explanation.
The production and collections guide addresses the underlying financial totals. The hygiene and recall guide addresses capacity and payment evidence. Resolving a category alone does not complete those reviews, and a fully classified percentage still does not measure profit.
For a sale, keep initial outreach seller-blind and omit owner and practice identity, exact location and identifying financial or staff details. Obtain an NDA before authorized identifying disclosure. Agree when staff should help resolve the mapping and who will brief the team. Review patient-data access separately from commercial confidentiality.
Carry the remaining uncertainty into a financing review or DSO discussion, rather than presenting the most favorable endpoint as established fact.
Summary
Hygiene percentage needs a complete classification or a clear statement of what is unresolved. The invented file supports a 20%–35% bound, not one proven share. New evidence narrows the range without creating activity or cash. Schedule a confidential discussion about the records needed for the next decision.
Frequently asked questions
Why does the base range run from 20% to 35%?
Verified hygiene is $40,000 of $200,000. Adding all $30,000 of unresolved production to hygiene would give $70,000 of $200,000.
Is the range a confidence interval?
No. It is an arithmetic bound under the fixed-total and nonnegative-amount assumptions. It assigns no likelihood to any result inside the range.
Why is 23.53% not the whole-practice share?
It divides $40,000 by only the $170,000 already classified, omitting $30,000 from the denominator. It is a different, narrower measure.
What do the two independent evidence tests change?
Assigning $12,000 to hygiene narrows the bound to 26%–35%. Separately assigning $15,000 to other work narrows it to 20%–27.5%. Neither creates activity or cash.
