Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $1,230,465 of the $1,231,189 with a category attached, or 99.9%. Kerr Corporation accounts for 64.8% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2023 at $475,337 and has fallen 98.5% since, to $7,008 in 2025. Among endodontics clinicians in CA 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.
