[1] Direct restorations for all cavity classes in anterior and posterior teeth
[2] Direct veneers
[3] Correction of tooth position and tooth shape (e.g. diastema closure, dwarfed tooth, etc.)
[4] Intraoral repairs of fractured restorations
CLEARFIL MAJESTY IC is an intra-oral, light-cured restorative composite that is available direct injection method into preparations with its syringe and replaceable tips. It is the radiopaque equivalent of 1mm aluminium and classified as a Type 1 and Class 2 (Group 1) material by ISO 4049. It is indicated for both anterior and posterior restorations and provides accurate color matching, high polishability and excellent physical properties.
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.
Test Item | Acceptance Criterion (Implicit) | Reported Device Performance |
---|---|---|
Sensitivity to ambient light | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Depth of cure | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Flexural strength | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Water sorption and solubility | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Shade, filling and restorative materials | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Color stability after irradiation and water sorption | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Radio-opacity | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Compressive strength | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Elastic modulus | Substantially equivalent to Primary Predicate device/Reference device. | The result demonstrated substantial equivalence. |
Intensity for curing | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Wavelength for curing | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Filler particle size distribution | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Surface hardness | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Curing time | Substantially equivalent to Primary Predicate device. | The result demonstrated substantial equivalence. |
Biocompatibility (ISO 10993-1:2009) | Substantially equivalent to Primary Predicate device/Reference device based on ingredients, indications, manufacturing process, contact part, and duration. | Substantially equivalent in biocompatibility. |
Shelf Life (based on ISO 4049:2009) | Properties maintained after accelerated aging equivalent to 48 months at 2-25 °C/36-77 °F. | Determined to be 48 months at 2-25 °C/36-77 °F. |
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.
