Disposable Prophy Angle is intended to be attached to a low speed dental handpiece and used by professional dentists and dental hygienists for polishing and cleaning the surface of teeth. It is intended for single use, and should be discarded after each patient.

Disposable Prophy Angle is a dental rotational device that consists of a prophy cup, a plastic body, a gear and a shaft with gear, which connects to a low-speed dental handpiece. The gear has the prophy cup attached to the end which holds dental tooth polishing paste. Prophy Angle is held in a dental handpiece by a shaft, which rotates the device's gear at speed as the polishing/ cleaning paste is applied to the surface of the teeth.

The provided text is a 510(k) premarket notification letter from the FDA regarding "Disposable Barrier Sleeves." This document is a regulatory clearance for a physical medical device (barrier sleeves), not an AI/software as a medical device (SaMD).

Therefore, the document does not contain any of the information requested in your prompt regarding acceptance criteria and study details for an AI/SaMD. Specifically:

• No AI/SaMD Performance: The device is a physical barrier sleeve, completely unrelated to AI performance metrics.
• No Test Set/Ground Truth: There is no mention of a test set, data provenance, expert ground truth, adjudication, or MRMC studies because these concepts are not applicable to the clearance of a disposable physical barrier.
• No Training Set: Similarly, there is no training set for a physical product.

The document indicates that the device is "substantially equivalent" to legally marketed predicate devices, which is the basis for its 510(k) clearance. The focus of the regulatory review for this product would have been on material safety, physical dimensions, intended use, and substantial equivalence to existing devices, not on algorithmic performance.
