The provided document is a 510(k) premarket notification for a dental cement product called "Nexus 3". It describes the device, its intended use, and claims substantial equivalence to a predicate device ("Nexus 2").

However, the document does not contain any information regarding acceptance criteria, performance studies, sample sizes, expert qualifications, ground truth establishment, or any of the other specific details requested in your prompt regarding artificial intelligence (AI) device performance evaluation.

The document states: "We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices..." This indicates that the approval was based on substantial equivalence to an existing device, not on a new performance study that would typically involve acceptance criteria and detailed study results as described in your prompt.

Therefore, I cannot provide the requested information from this document. The information you are asking for is typically found in performance study reports for AI/ML-enabled devices, which this document is not.
