What this record shows
This record is dominated by royalties or licence payments: $5,872,568 of the $6,070,564 with a category attached, or 96.7%.

Among endodontics clinicians in MA 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.
