Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (47.3%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. Dentsply Sirona Inc accounts for 68.4% of it on its own, with 12 other manufacturers making up the rest. Among periodontics clinicians in IL with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 268 payments — averaging $1999.58 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
