Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (57.9%), speaking fees and education — rather than concentrated in one kind of arrangement. Sonendo Inc accounts for 94.2% of it on its own, with 7 other manufacturers making up the rest. Reporting peaked in 2019 at $200,020 and has fallen 99.9% since, to $226 in 2025. Among endodontics clinicians in AZ 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 194 payments — averaging $2936.55 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.
