AI/ML Overview

This looks like a 510(k) premarket notification for a dental device, specifically "High Speed Handpieces and Accessories." The document demonstrates substantial equivalence to existing predicate devices, rather than establishing de novo acceptance criteria and proving performance through a standalone study with ground truth.

Therefore, many of the requested categories in your prompt are not applicable to the information provided in this 510(k) summary. I cannot extract information related to:

  • Sample size used for the test set and data provenance: This is not a study proving a diagnostic or AI device's performance against a ground truth. The tests are for engineering specifications.
  • Number of experts used to establish the ground truth for the test set and their qualifications: Not applicable, as there's no diagnostic ground truth being established.
  • Adjudication method: Not applicable.
  • Multi reader multi case (MRMC) comparative effectiveness study: Not applicable, as this is a physical dental device, not an AI or diagnostic tool.
  • Standalone (i.e. algorithm only without human-in-the-loop performance) study: Not applicable.
  • Type of ground truth used: Not applicable.
  • Sample size for the training set: Not applicable.
  • How the ground truth for the training set was established: Not applicable.

However, I can extract the acceptance criteria and reported device performance from the "Non-clinical Testing" section and the "Comparison of Technical Features" table, as these relate to the device's engineering specifications.

Here's a summary of the available information:

1. Table of Acceptance Criteria and the Reported Device Performance

The document states: "All the test results demonstrate the performance of High Speed Handpieces and Accessories meets the requirements of its pre-defined acceptance criteria and intended uses." While specific numerical "acceptance criteria" and "reported performance" are not presented side-by-side in a table in the exact format you requested for each test, the document implies that the device passed the tests outlined by the referenced standards.

From the "Comparison of Technical Features" section, we can infer performance characteristics based on comparison to predicate devices, which serve as a benchmark for "acceptance" in a 510(k) context.

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

This information is not provided in the summary. The document focuses on demonstrating substantial equivalence through comparison to predicate devices and adherence to recognized standards, rather than detailing a specific experimental test set. The manufacturer is based in Taiwan.

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)

High Speed Handpieces and Accessories are intended for removing carious material, excess filling material, cavity and crown preparation, finishing tooth preparations and restorations, root canal preparations and polishing teeth.

6-7 Device Description:

High Speed Handpieces and Accessories include 45° High Speed Handpieces, 90° High Speed Handpieces and Couplings. The device description of High Speed Dental Handpieces and Accessories are as follows.

The models of 45° High Speed Handpieces are A45series (A45L, A45, A45M4) and 90° High Speed Handpieces are A6series (A6KL, A6L, A6, A6M4, A6B2), A5series (A5KL, A5K, A5L, A5, A5M4, A5B2), A4series (A4, A4M4, A4B2), A3series (A3, A3M4, A3B2), E-6510series (E-6510K, E-6510N), E-6500series (E-6500K, E-6500N), E-6110series (E-6110K, E-6110N), E-6100series (E-6100K, E-6100N), HPXseries (HPX4CML-Ti, HPX4CQ, HPX4CQ-Ti), HPMseries (HPM1CML, HPM1CQ, HPM1C4, HPM1C2, HPM1S4, HPM1S2) and HPKseries (HPK1C2, HPK1S4, HPK1S2). And the accessories of High Speed Handpiece are Couplings, the models of Accessories are

{5}------------------------------------------------

Concerning the head of handpiece and angle of shaft, the handpiece could be 45° or 90° . In general, dentist usually uses 90° handpiece having teeth treatment. Except for wisdom teeth, 45° handpiece is considered more desirable for wisdom teeth operation. It is because the 45° angle is more appropriate for the angle of eruption of wisdom teeth. Coupling is the accessory for handpiece to connect with tubes of dental unit. It could be divided into four types. There are 2-hole coupling (drive air and spray water holes), 4hole coupling (drive air, exhaust air, spray air and spray water holes), 5-hole coupling (drive air, exhaust air, spray air and spray water and fibre optic holes) and 6-hole coupling (drive air, exhaust air, spray air, spray water and two of electrical contacts holes). The use of the coupling of handpiece is due to the number of tubes of dental unit.
