Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $172,601 of the $231,472 with a category attached, or 74.6%. Planmeca USA, Inc. accounts for 82.1% of it on its own, with 4 other manufacturers making up the rest. Reporting peaked in 2022 at $61,963 and has fallen 99.4% since, to $382 in 2025. Among periodontics clinicians in SC 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 179 payments — averaging $1293.14 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
