It is indicated for both anterior and posterior restorations and provides accurate color matching, high polishability and excellent physical properties.

AI/ML Overview

The medical device in question is CLEARFIL MAJESTY IC, a dental light-cured restorative composite. The provided document is a 510(k) premarket notification summary, which focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting a detailed clinical study for novel performance claims. As such, the information you've requested about acceptance criteria and study particulars for device performance in a clinical setting is not fully available in this type of submission.

This submission primarily relies on non-clinical testing to demonstrate that the physical and mechanical properties of the subject device are substantially equivalent to those of the predicate device(s).

Here's a breakdown of the requested information based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state numerical "acceptance criteria" for each test item but rather states that the "Result demonstrated substantial equivalence" to the predicate device. The underlying acceptance criterion for each test would be that the subject device's performance falls within a range considered comparable to the predicate device, as defined by relevant ISO standards (specifically ISO 4049:2009 for polymer-based restorative materials) and FDA guidance for dental composite resin devices.

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

The document describes non-clinical testing (e.g., material property tests) rather than a clinical test set involving human subjects. Therefore, information regarding "sample size for the test set" in a clinical context and "data provenance (e.g. country of origin of the data, retrospective or prospective)" is not applicable or provided. The tests described are laboratory-based evaluations of material properties.

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

This information is not applicable. The evaluations were non-clinical material property tests, not assessments requiring expert consensus on a test set (e.g., image interpretation). The "ground truth" for these tests would be the established scientific methods and resulting measurements according to ISO standards.

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

This information is not applicable as the study involved non-clinical material property testing, not an adjudication process for expert opinions.

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. The device is a dental restorative material, not an AI-assisted diagnostic or therapeutic device. No MRMC study or AI assistance is mentioned or relevant to this 510(k) submission.

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 a dental restorative material, not an algorithm or AI system.

7. The Type of Ground Truth Used

For the non-clinical tests, the "ground truth" is based on established scientific and engineering standards and methodologies, specifically:

  • ISO 4049: 2009 (Dentistry - Polymer-based restorative and materials) for physical and mechanical properties.
  • "Dental Composite Resin Devices – Premarket Notification [510(k)] Submissions – Guidance for Industry and FDA Staff" for additional physical properties.
  • ISO 10993-1:2009 for biological evaluation (biocompatibility).

Performance is compared against the predicate device's performance under these established methods.

8. The Sample Size for the Training Set

This information is not applicable. This is not a machine learning device, so there is no concept of a "training set."

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

This information is not applicable. There is no training set for this device.
