IMPREGUM® PENTA® DUOSOFT is classified as an impression material (21 C.F.R. § 872.3660) because it is a device intended to reproduce the structure of a patient's teeth.

This document is a 510(k) Pre-market Notification for a dental impression material called IMPREGUM® PENTA® DUOSOFT. It states that the device is substantially equivalent to a predicate device, PERMADYNE® PENTA®, and therefore, no new studies demonstrating performance against acceptance criteria were conducted or presented.

The basis for substantial equivalence is primarily that the new device uses the same materials and processes for manufacturing and packaging as the predicate device. Furthermore, all chemical components of the new device are either present in the predicate device or in other 510(k) cleared impression materials manufactured by ESPE.

Therefore, the following information cannot be extracted from the provided text as the application relies on substantial equivalence to a predicate device rather than new performance studies with specific acceptance criteria:

1. A table of acceptance criteria and the reported device performance: Not applicable, as performance against new acceptance criteria was not presented.
2. Sample size used for the test set and the data provenance: Not applicable.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
4. Adjudication method for the test set: Not applicable.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This is a dental impression material, not an AI diagnostic device.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable.
7. The type of ground truth used: Not applicable.
8. The sample size for the training set: Not applicable.
9. How the ground truth for the training set was established: Not applicable.
