The Midwest Motor Control Module includes a control unit, ports for three motors, an apex location port, and a peristaltic pump port. The motor ports are compatible with the Midwest Power Lux and Midwest Power Lux Implant.

The Midwest Power Lux electric micromotor is intended for use as a drive for rotating and oscillating straight and contra-angle hand pieces for endodontic and general dental purposes.

The Midwest Power Lux Implant motor is intended for use in implant placement and includes a closed system for delivery of sterile solution via peristaltic pump operation.

The apex locator supports the dentist in the determination of the working length during the endodontic treatment.

These motors are to be driven by the control unit. The control unit is an internal component of a dental delivery system.

The use of this product is intended exclusively for duly qualified dental practitioners.

This device is a system that includes a control module (internal component of a dental delivery system) that can operate up to three dental motors, an apex locator, and a peristaltic pump. The motors do not operate concurrently. The motors that can be attached include dental motors and dental implant motors. The motors included with this module in this subject system are the Midwest Power Lux and Midwest Power Lux Implant. Also included is the cable, file, and tip required for the operation of the apex location technology. The programming supports manual use of the apex locator as well as combined use of the locator with a motor. The included peristaltic pump and control allows for sterile solution irrigation when required.

The provided FDA 510(k) Clearance Letter for the "Motor and Apex Module (MaAM)" (K251811) does not contain information about acceptance criteria or a study that proves the device meets specific performance criteria related to the apex locator's accuracy or the motors' performance in a clinical setting.

The document primarily focuses on regulatory approval, substantial equivalence to predicate devices, and general safety and performance testing. While it mentions the device supports "determination of the working length during the endodontic treatment" (for the apex locator) and drives "rotating and oscillating straight and contra-angle hand pieces for endodontic and general dental purposes" (for the motors), it does not provide the specific performance metrics (e.g., accuracy, precision, torque output, speed stability) for these functions, nor the studies that verified them.

The "Non-Clinical and/or Clinical Tests Summary & Conclusions" section explicitly states: "Not applicable (no clinical data necessary)." This indicates that the FDA clearance was based on non-clinical testing, primarily focused on safety, electrical compatibility, and adherence to established industry standards (ISO 14457 for dental motors, IEC 62471 for photobiological safety, and ISO 3964 for dental coupling dimensions).

Therefore, based solely on the provided document, I cannot generate the requested table and study details. The information about performance acceptance criteria, sample sizes, expert involvement, adjudication, MRMC studies, standalone performance, and ground truth establishment for clinical effectiveness is absent.

However, I can extract and present the information that is available in the document regarding testing:

Summary of Device Performance and Testing (Based on Available Information in K251811)

The provided 510(k) clearance letter for the Motor and Apex Module (MaAM) establishes substantial equivalence to predicate devices based on non-clinical testing. The document explicitly states "Not applicable (no clinical data necessary)", indicating that the clearance did not involve clinical studies assessing the device's functional performance in a patient setting, such as the accuracy of the apex locator or the clinical efficacy of the motors.

The testing highlighted in the document focuses on compliance with international standards and mechanical/electrical safety.

1. Table of Acceptance Criteria and Reported Device Performance

Given that clinical performance acceptance criteria and respective reported device performance data are not detailed in the provided document, the table below reflects the types of non-clinical testing mentioned and the general conclusion of meeting specifications.

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

• Sample Size: Not specified in the document. Testing was non-clinical (bench/laboratory).
• Data Provenance: Non-clinical (bench testing in a laboratory). Country of origin is not specified for the test data itself, but the applicant (Dentsply Sirona Inc.) is located in the United States. The testing was retrospective in the sense that it was conducted prior to the submission for clearance.

3. Number of Experts Used to Establish Ground Truth and Qualifications

• Not applicable. The clearance was based on non-clinical, standard-driven testing. There was no clinical ground truth established by experts for performance assessment in a patient setting.

4. Adjudication Method for the Test Set

• Not applicable. No clinical test set or subjective assessment requiring adjudication (like image interpretation) was mentioned.

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

• No MRMC study was done. The document explicitly states "Not applicable (no clinical data necessary)". Therefore, no effect size of human readers improving with AI vs. without AI assistance can be reported. The device is not an AI-assisted diagnostic tool in the sense of image interpretation.

6. Standalone Performance (Algorithm Only)

• Not applicable. The device is a physical medical device (motors, control module, apex locator) and not an algorithm or AI software for standalone performance evaluation in a diagnostic context. Its "performance" refers to its physical and electrical operation within specified limits, not its diagnostic accuracy.

7. Type of Ground Truth Used

• Not applicable, for clinical performance. For the non-clinical tests, the "ground truth" was established by the specifications defined in the referenced ISO and IEC standards (e.g., a motor must achieve a certain speed, a coupling must fit, light emission must be within safety limits). There was no "expert consensus, pathology, or outcomes data" ground truth as would be used for diagnostic accuracy studies.

8. Sample Size for the Training Set

• Not applicable. This device is hardware with embedded control software; it is not a machine learning or AI model that requires a training set in the typical sense of algorithm training on data.

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

• Not applicable. As above, this device does not utilize a "training set" in a machine learning context.

In conclusion, the FDA 510(k) clearance for the MaAM (K251811) was granted based on non-clinical testing demonstrating conformance to relevant safety and performance standards for dental motors, photobiological safety, and dental coupling dimensions. The document explicitly states that no clinical data was necessary for this clearance, meaning functional performance (e.g., apex locator accuracy, motor clinical efficacy) in a patient setting was not assessed as part of this submission.
