    The subject device is a single-component, light-cured bonding agent that allows simultaneous treatment of both dentin and enamel.

    AI/ML Overview

    The provided text describes the regulatory submission for a dental bonding agent, CLEARFIL TRI-S BOND PLUS, and references studies conducted to demonstrate its substantial equivalence to predicate devices. However, the document does not contain explicit "acceptance criteria" in a quantitative tabular format or detailed "studies that prove the device meets acceptance criteria" with the specific information requested in your prompt (e.g., sample sizes for test/training sets, data provenance, expert ground truth details, MRMC studies, standalone performance details).

    Instead, the submission focuses on demonstrating substantial equivalence based on

    1. Intended uses
    2. Chemical ingredients/safety (biocompatibility)
    3. Technological characteristics/effectiveness and performance.

    The document indicates that for effectiveness and performance, "certain tests were performed on this device, in comparison with the predicate device and it was confirmed that this device was substantially equivalent to the predicate device in terms of the effectiveness and performance." Specifically, the following tests are mentioned:

    • Tensile bond strength test
    • Fluoride releasing property

    The results of these tests "exhibited almost the same results for the subject device indicating that the subject device was as effective as and performs as good as or better than the predicate device."

    Without the full study reports, which are not included in this summary, the detailed information requested cannot be fully extracted. However, based on the provided text, here's what can be inferred:


    1. A table of acceptance criteria and the reported device performance

    Acceptance Criteria (Inferred from "Substantially Equivalent")Reported Device Performance
    Tensile Bond Strength: Comparable to or better than predicate devices (CLEARFIL TRI-S BOND, CLEARFIL DC BOND).Exhibited "almost the same results" as the predicate device for tensile bond strength, indicating it was "as effective as and performs as good as or better than" the predicate device.
    Fluoride Releasing Property: Comparable to or better than predicate devices (CLEARFIL TRI-S BOND, CLEARFIL DC BOND).Exhibited "almost the same results" as the predicate device for fluoride releasing property, indicating it was "as effective as and performs as good as or better than" the predicate device.
    Biocompatibility: Meet ISO 10993 series and ISO 7405 standards.2 new ingredients evaluated with ISO 10993 series and ISO 7405 and "it was confirmed that these substances were biocompatible." All other ingredients previously used in predicate devices with no reported problems.

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

    • Sample Size for Test Set: Not specified in the provided summary.
    • Data Provenance: Not specified in the provided summary.
      • The submitter is Kuraray Medical Inc., located in Japan, suggesting the studies likely originated from there, but this is an inference, not stated directly about the data itself.
      • The studies were part of a 510(k) submission, typically involving prospective testing for performance evaluations.

    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)

    • Not applicable as the tests described (tensile bond strength, fluoride release) are objective laboratory measurements, not subjective evaluations requiring expert ground truth in the way medical imaging interpretation might.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    • Not applicable for objective laboratory measurements like tensile bond strength or fluoride release.

    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

    • No, this type of study is not mentioned. The device is a dental bonding agent, not an AI-powered diagnostic tool for human readers.

    6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

    • Not applicable. The device is a physical product (dental bonding agent), not an algorithm. Its performance is inherent to the material properties.

    7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

    • For Tensile Bond Strength and Fluoride Releasing Property: The "ground truth" would be the direct measurement of these physical/chemical properties using established laboratory testing protocols, likely aligned with ISO or ASTM standards, and validated against the performance of predicate devices.
    • For Biocompatibility: The ground truth was established by evaluation against ISO 10993 series and ISO 7405 standards.

    8. The sample size for the training set

    • Not applicable. The description refers to a medical device (dental bonding agent), not an AI algorithm that requires a training set. Development of such a product involves formulation and testing, but not in the "training set" sense for AI.

    9. How the ground truth for the training set was established

    • Not applicable as there is no "training set" in the context of this device.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for a dental bonding agent, CLEARFIL TRI-S BOND PLUS Single Dose. The submission aims to demonstrate substantial equivalence to predicate devices, focusing on chemical ingredients, safety, and technological characteristics/performance.

    Here's an analysis of the acceptance criteria and study information based on the provided text:

    Acceptance Criteria and Study Details for CLEARFIL TRI-S BOND PLUS Single Dose

    The provided information focuses on demonstrating substantial equivalence to existing predicate devices rather than establishing novel safety or efficacy criteria that would necessitate a rigorous clinical trial with pre-defined acceptance criteria for a new device. For devices seeking 510(k) clearance, the "acceptance criteria" are generally that the new device performs "as good as or better than" the predicate device in key performance characteristics relevant to its intended use.

    1. Table of Acceptance Criteria and Reported Device Performance

    Given that this is a 510(k) submission for substantial equivalence, formal, quantitative acceptance criteria with specific threshold values (e.g., "tensile strength > X MPa") are not explicitly stated as they would be for a novel device. Instead, the "acceptance criteria" can be inferred as demonstrating similar or superior performance to the predicate devices.

    Acceptance Criterion (Inferred from substantial equivalence claim)Reported Device Performance (CLEARFIL TRI-S BOND PLUS Single Dose)
    BiocompatibilityConfirmed to be biocompatible (based on ISO 10993 series and ISO 7405 evaluation for new ingredients).
    Tensile Bond Strength"Almost the same results" as the predicate device (CLEARFIL TRI-S BOND).
    Fluoride Releasing Property"Almost the same results" as the predicate device (CLEARFIL TRI-S BOND).
    Overall Effectiveness and Performance"As effective as and performs as good as or better than the predicate device."

    Study Description:
    The study was conducted to demonstrate substantial equivalence to predicate devices, specifically "CLEARFIL TRI-S BOND" for performance aspects. It involved:

    • Biocompatibility testing: For two new chemical ingredients, evaluation was done referring to ISO 10993 series and ISO 7405.
    • Performance testing: Tensile bond strength test and Fluoride releasing property were performed.

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

    The document does not explicitly state the sample sizes used for the tensile bond strength test, fluoride releasing property test, or the biocompatibility evaluations.

    The data provenance is not specified regarding country of origin or whether it was retrospective or prospective. It is implied to be laboratory testing for performance characteristics and ingredient evaluations rather than patient data.

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

    This information is not applicable in the context of this 510(k) summary. The "ground truth" for chemical composition, biocompatibility, and physical properties (like bond strength) is established through standardized laboratory tests and material science principles, not through expert consensus on patient data.

    4. Adjudication Method for the Test Set

    This information is not applicable. Adjudication methods (like 2+1 or 3+1) are typically used for clinical image interpretation or diagnostic studies involving human readers, which is not the nature of the tests described for this dental bonding agent.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study involves human readers interpreting cases with and without AI assistance and is relevant for diagnostic imaging devices. The CLEARFIL TRI-S BOND PLUS Single Dose is a material (dental bonding agent), not a diagnostic or AI-powered device.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

    No, a standalone performance study in the context of an algorithm or AI was not done. This device is a material, not a software algorithm. The "standalone" performance refers to the device's inherent material properties as tested in the laboratory.

    7. The Type of Ground Truth Used

    The "ground truth" for the tests performed was based on objective laboratory measurements and material science standards.

    • Biocompatibility: Determined by adherence to ISO 10993 series and ISO 7405 standards for material safety.
    • Tensile Bond Strength: Measured quantitatively in a laboratory setting to evaluate the material's adhesive properties.
    • Fluoride Releasing Property: Measured quantitatively to assess this specific characteristic of the material.

    8. The Sample Size for the Training Set

    This information is not applicable. The concept of a "training set" is relevant for machine learning algorithms or AI models. This submission is for a medical device (dental bonding agent) that does not involve AI or machine learning. The studies described are for material characterization and performance comparison.

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

    This information is not applicable as there is no "training set" for this device.
