510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.
Zinc Oxide Eugenol
Dental
Zinc Oxide Eugenol (ZOE) is a dental material composed of zinc oxide powder and eugenol liquid that, when mixed, forms a paste used as a temporary cement, sedative base, pulp capping agent, or impression material due to its obtundent and antimicrobial properties. It is classified as FDA Class 1 (lowest risk), subject only to general controls. The product code is EMB, regulated under 21 CFR 872.3275 in the Dental (DE) specialty.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
