Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 7 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 4 manufacturers reported payments, led by Patterson Companies, Inc. at 46.9% of the total.
Across 7 payments — averaging $70.20 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

- Tulsa Dental Products LLC$153
- Dentsply Sirona Inc$58
- Envista Holdings Corporation$50
Across 6 payments — averaging $152,637 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.

Most of this is food and beverage — typically meals provided during product presentations at a clinic or hospital. Nationally that is the single largest category of reported payments by count.
General payments by program year
Who reported the general payments
Companies are grouped under their corporate parent — a single manufacturer often files under several CMS reporting entities. Research and ownership payments are counted separately and are not in this table.
| Company | Payments | Total |
|---|---|---|
| Patterson Companies, Inc. | 2 | $230 |
| Tulsa Dental Products LLC | 2 | $153 |
| Dentsply Sirona Inc | 2 | $58 |
| Envista Holdings Corporation | 1 | $50 |
What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
How this compares
$491 in reported general payments places this provider in the 65th percentile of 3,138 dentist providers in Illinois.
Most prescribed under Part D
