Therefore, I cannot fulfill your request for information regarding AI acceptance criteria and a study proving the device meets these criteria based on the provided text. The text does not describe such a study or an AI component.

To directly address your request given the provided text's limitations, here's what I can extract and what I cannot:

1. A table of acceptance criteria and the reported device performance:

The document mentions validation and verification testing against various standards and guidance documents. These are the "acceptance criteria" for the general device performance and safety. The "reported device performance" is simply that the "results of the exit [sic] the requirements of the following standards and guidance."

2. Sample size used for the test set and the data provenance:

• Not specified. The document does not provide details on the sample sizes for the performance tests, only lists the standards against which they were tested. Data provenance (e.g., country of origin, retrospective/prospective) is also not mentioned for these non-clinical tests.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not applicable/Not specified. For the non-clinical tests mentioned (e.g., electrical safety, sterilization), "ground truth" as it applies to clinical data review by experts is not relevant. The conformity to standards would be assessed through engineering and quality testing, not expert clinical review.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

• Not applicable/Not specified. This is relevant for clinical studies with expert reviewers, not for the type of non-clinical device performance and safety testing described.

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:

• No evidence of an MRMC study. The document describes a traditional 510(k) pathway for a dental handpiece system, focusing on substantial equivalence based on technical characteristics and non-clinical performance (safety, reprocessing, software lifecycle, etc.), not a comparative effectiveness study involving human readers or AI assistance.

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

• Not applicable. The device described (Surgic Pro2) is a dental surgical system with a micromotor, handpieces, and control unit. While it has software and Bluetooth connectivity (e.g., to display ISQ values from another device), it is not an AI/algorithm-only device for diagnosis or image analysis. Its software controls mechanical functions, not an independent interpretive algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• Not applicable/Compliance with standards. For the non-clinical tests performed, the "ground truth" is typically defined by the specified parameters and limits within the engineering standards (e.g., specific electrical leakage limits, torque values, sterilization parameters).

8. The sample size for the training set:

• Not applicable. This device is not described as having an AI/ML component that would require a training set.

9. How the ground truth for the training set was established:

• Not applicable. As above, no AI/ML training set is indicated.

Air Motor is intended for the following application(s): Driving the handpiece for the tooth restoration, prophylaxis, and root canal preparation.

The air motor converts the compressed air supplied from the dental unit into rotary motion. The rotation is transmitted to instruments for tooth restoration, prophylaxis, and root canal preparation connected to straight and geared angle handpieces.

The provided document is a 510(k) premarket notification for a dental air motor. The core of this document is a comparison of the subject devices (Air Motor FX204 M4 and Air Motor M205) against predicate devices to demonstrate substantial equivalence, rather than a clinical study evaluating the device against acceptance criteria in the typical sense of AI/ML performance.

Therefore, many of the requested elements for describing "acceptance criteria and the study that proves the device meets the acceptance criteria" for AI/ML devices are not applicable in this context. The document focuses on performance testing to demonstrate safety and effectiveness for a mechanical device.

However, I can extract the information relevant to how the device's technical specifications and performance were evaluated against established standards and predicate devices.

Here's a breakdown of the relevant information from the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are not explicitly stated as numerical thresholds in a table format for each specific performance metric in the way you might see for an AI algorithm (e.g., AUC > 0.90). Instead, the acceptance criterion for this 510(k) submission is to demonstrate "substantial equivalence" to legally marketed predicate devices by showing that the subject devices perform similarly and meet relevant safety and performance standards.

The closest we have to "reported device performance" and "acceptance criteria" are the comparison tables (Table 1 for FX204 M4 and Table 2 for M205) and the "Judgement" column, which indicates if the subject device is "Same," "Similar," or "Different" to the predicate. For "Different" or "Similar" aspects, further testing or justification is provided to demonstrate that the difference does not raise new questions of safety or effectiveness.

Below are tables summarizing the key performance and safety aspects evaluated and how the subject device's performance compared to the predicates, along with the implicit "acceptance criteria" through this comparison.

For Air Motor, FX204 M4 (model without spray) - (Based on "DEVICE AND PREDICATE COMPARISON TABLE-1")

For Air Motor, M205 (Internal Spray equipped) - (Based on "DEVICE AND PREDICATE COMPARISON TABLE-2")

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

• Sample Size for Test Set: The document mentions "Statistical calculation of sample size" under performance testing, but does not provide specific numbers for units tested for each type of test. The nature of these tests (e.g., drop test, reprocessing resistance, water leakage, vibration, sterilization validation) typically involves testing a representative sample of devices, but the exact number isn't quantified in the provided text.
• Data Provenance: Not explicitly stated, however, the applicant is "NAKANISHI INC." based in "700 Shimohinata Kanuma Tochigi, 322-8666, Japan". It's highly probable the testing was conducted in Japan or through certified testing facilities used by the manufacturer. The data would be prospective in the sense that these tests are performed on the manufactured devices to ensure they meet specifications.

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

• This concept typically applies to clinical studies or studies involving human interpretation (e.g., radiology expert review for AI algorithms). This submission is for a mechanical dental device.
• The "ground truth" here is compliance with engineering standards (e.g., ISO 14457 for dental handpieces), safety standards (e.g., ISO 10993 for biocompatibility), and the performance characteristics of the predicate devices.
• No "experts" in the sense of clinical reviewers establishing ground truth for individual cases are mentioned. Instead, the evaluations are based on technical testing by qualified personnel in accredited laboratories.

4. Adjudication Method for the Test Set

• Adjudication methods (like 2+1, 3+1) are used in studies involving human interpretation or subjective assessments, often in AI/ML performance evaluation where ground truth is based on expert consensus.
• This is not applicable here as the evaluation is based on objective measurements against engineering standards and comparison with predicate device specifications.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• Not applicable. This is a submission for a mechanical dental motor, not an AI/ML diagnostic or assistive device that would involve human readers interpreting cases.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

• Not applicable. This device does not involve a software algorithm in the context of an AI/ML device requiring this type of performance evaluation.

7. Type of Ground Truth Used

• The "ground truth" for this submission is primarily technical specifications/performance derived from engineering standards (e.g., ISO 14457, ISO 10993) and comparison to the known and established safety and effectiveness of legally marketed predicate devices.
• For example, passing ISO 14457 test methods indicates the device performs as expected for a dental handpiece. Biocompatibility is "ground-truthed" by adherence to ISO 10993.

8. Sample Size for the Training Set

• Not applicable. This is a mechanical device, not an AI/ML algorithm that requires a "training set."

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

• Not applicable, as there is no "training set" for this type of device.

The document focuses on regulatory compliance, non-clinical performance testing (bench testing, sterilization, cleaning, biocompatibility), and a comparison to a predicate device to establish substantial equivalence.

Therefore, many of the requested fields cannot be filled from the provided text.

Here's a breakdown of what can be extracted and what is explicitly not present:

1. A table of acceptance criteria and the reported device performance

• Not present in the document. The document states that "The product's conformance with applicable international and internal standards was verified in the course of bench testing" and "Tests were performed on the subject device including verification/validation testing to internal functional specifications which demonstrated that the device is substantially equivalent." However, specific numerical acceptance criteria (e.g., minimum torque, maximum vibration) and the corresponding measured performance values are not provided.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

• Not present in the document. The document mentions "bench testing" and "verification/validation testing to internal functional specifications," but it does not specify sample sizes for these tests or the data provenance.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

• Not applicable / Not present. This type of information is typically relevant for studies involving human interpretation or clinical endpoints. Since this document describes non-clinical performance testing for a dental handpiece, there's no mention of experts establishing a "ground truth" for a test set in the conventional sense of diagnostic or AI-driven medical devices.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable / Not present. Similar to point 3, this is relevant for studies involving human readers and interpretations, which are not described here.

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

• No, this was not done. The document explicitly states: "Clinical Testing: Clinical testing was not required as non-clinical testing is believed to be sufficient for a determination of substantial equivalence of the FX Contra handpieces." Therefore, no MRMC study or AI assistance evaluation was performed as per this document.

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

• Not applicable. This device is a dental handpiece, not an algorithm or AI-driven system.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

• Not applicable / Not present in a clinical sense. For the non-clinical tests mentioned (sterilization, performance to ISO standards, cleaning, biocompatibility), the "ground truth" would be the specifications and requirements defined by the respective standards. However, actual data points or methods for confirming these are not detailed.

8. The sample size for the training set

• Not applicable. This is not an AI/ML device that requires a training set.

9. How the ground truth for the training set was established

• Not applicable. This is not an AI/ML device that requires a training set.

Summary of available information related to performance testing:

The device is the FX Contra dental handpiece.

The document indicates that the device's substantial equivalence largely relies on non-clinical performance testing and a comparison to a predicate device (SciCan GmbH SANAO Dental Handpieces, K132356).

Performance Testing Mentioned:

Here's an analysis of the acceptance criteria and the study information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are not explicitly stated as separate targets but are implied through the comparison with predicate devices and claims of conformance to ISO standards. The performance characteristics of the proposed Stainless Turbine and the predicate/reference devices are presented in Tables 1 and 2 of the document.

2. Sample size used for the test set and the data provenance
The document states: "Tests were performed on the handpieces including verification/validation testing to internal functional specifications which demonstrated that the device is substantially equivalent to FDA cleared devices." However, it does not provide any specific sample sizes for the test set or details about the data provenance (e.g., country of origin, retrospective or prospective). It simply refers to "bench testing."

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. The testing appears to be functional and engineering-based (bench testing) rather than involving human experts for ground truth establishment.

4. Adjudication method for the test set
This information is not provided in the document, as the testing described is primarily technical and quantitative, not involving clinical adjudication.

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
This information is not applicable to this device. The Stainless Turbine is a mechanical dental handpiece, not an AI-powered diagnostic or assistive tool for human readers/clinicians. Therefore, an MRMC comparative effectiveness study involving human readers and AI assistance would not be relevant.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable to this device, as it is a mechanical dental tool and not an algorithm or AI system.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the technical performance characteristics (rotation speed, torque, noise level, pressure), the "ground truth" or reference for comparison appears to be the specifications and performance of legally marketed predicate and reference devices, as well as conformance to international standards (e.g., ISO 1797-1, ISO 9168, ISO 14457:2012). For sterilization, the ground truth is conformance to ISO 17665-1:2006. For biocompatibility, it's ISO 10993-1:2018 and FDA guidance. There is no mention of expert consensus, pathology, or outcomes data being used as ground truth for verification of this type of device.

8. The sample size for the training set
This information is not applicable to this device, as it is a mechanical device and not an algorithm or AI system that requires a "training set."

9. How the ground truth for the training set was established
This information is not applicable for the same reason as point 8.
