Payments from drug & device makers
What this record shows
The money is spread across several categories — food and beverage (56.9%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. 13 manufacturers reported payments, led by Dentsply Sirona Inc at 32.1% of the total. Reporting peaked in 2022 at $3,253 and has fallen 92.7% since, to $237 in 2025. Among oral and maxillofacial surgery clinicians in TN with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 169 payments — averaging $47.28 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
