AI/ML Overview

The APOZA ULTRASONIC SCALER AND ENDODONTIC'S UNIT Models: SELECTOR U2 did not provide specific acceptance criteria or an analytical study. The information focuses on its substantial equivalence to a predicate device and its intended use.

Here's a breakdown of the available information based on your request:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria	Reported Device Performance
Not explicitly stated in the provided document. The submission relies on "substantial equivalence" to a predicate device.	The device's performance is validated through "performance testing" to show substantial equivalence to the predicate device, SATELEC SUPRASSON P5 BOOSTER (K961158). The document states that the comparison and validation results "show that the subject device is substantially equivalent to predicated device and is safe and effective in its intended use."

2. Sample Size Used for the Test Set and the Data Provenance

This information is not provided in the document.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

This information is not provided in the document.

4. Adjudication Method (e.g., 2+1, 3+1, none) for the Test Set

This information is not provided in the document.

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

There is no mention of an MRMC comparative effectiveness study, nor is there any indication that AI is involved in this device. This is a conventional medical device, an ultrasonic scaler.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

This information is not applicable as the device is an ultrasonic scaler, not an algorithm.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

The document broadly mentions "performance testing" and comparison with a predicate device to establish safety and effectiveness. It does not explicitly state the type of ground truth used, but it would likely involve standard dental performance metrics for ultrasonic scalers (e.g., calculus removal efficiency, tip vibration patterns, power output stability, safety parameters) rather than complex clinical outcomes data or expert consensus on diagnostic tasks.

8. The Sample Size for the Training Set

This information is not provided in the document.

9. How the Ground Truth for the Training Set Was Established

This information is not provided in the document. As this is a traditional medical device, a "training set" in the context of machine learning is not applicable here. The "training" would refer to internal validation and testing during the device's design and manufacturing process, which is not detailed in a 510(k) summary in this manner.

Comparison to Predicate Devices: The APOZA Ultrasonic Scaler, Sciector U2, has

been carefully compared to legally marketed devices with respect to intended use and technological characteristics. In addinon, performance testing has been done to validate the performance of the device. The comparison and validation results presented in this 510k notification to the FDA show that the subject device is substantially equivalent to predicated device and is safe and effective in its intended use. We believe that the APOZA Ultrasonic Scaler, Selector U2 is substantially equivalent to the predicate device, i.e., SATELEC SUPRASSON P5 BOOSTER(K961158), and the data provided support the safety and effectiveness of Selector 'J2 for the intended uses.

Dear Mr. Min-Tch:

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 (301) 594-4613.
