I am sorry, but based on the provided text, there is no information regarding acceptance criteria or a study that proves the device meets specific acceptance criteria.

The document is a 510(k) summary for a dental material called ZirBlock®. It focuses on demonstrating substantial equivalence to predicate devices (other legally marketed dental materials) rather than presenting performance data against defined acceptance criteria.

Here's why I cannot provide the requested information:

No Acceptance Criteria Defined: The summary states: "None required. The claim of substantial equivalence is based on comparisons of formulations, mechanical characteristics, and intended uses of the devices to legally marketed predicates and to the IDENTIFICATION of porcelain powders in 21 CFR 872.6660." This explicitly states that performance data against acceptance criteria was not required for this submission.
No Performance Study Described: The document mentions "comparisons of formulations, mechanical characteristics, and intended uses," but it does not detail any specific study design, methodology, results, or statistical analysis that would constitute a "study that proves the device meets the acceptance criteria."
Focus on Substantial Equivalence: The entire submission is built around the concept of substantial equivalence to existing predicate devices, meaning the device is considered as safe and effective as devices already on the market, without necessarily requiring a new, independent performance study against novel acceptance criteria.

Therefore, since the input document does not contain the information you've requested, I cannot complete the table or answer the specific questions about sample size, expert ground truth, adjudication, or MRMC studies.

Dear Mr. Kamm:

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 marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
