    Intended Use

    Rennou™ Varnish is indicated for the relief of tooth hypersensitivity through the mechanical occlusion of dentinal tubules.

    Device Description

    Rennou™ Varnish is a cavity varnish intended for professional use as a topical application on prepared tooth surfaces. This fluoride-free varnish creates a rosin-based film that prevents penetration of restorative material into the dentinal tissue and provides relief of tooth hypersensitivity by occluding open dentinal tubules. Unit-dose varnish and applicator are packaged together in individual thin, sealed trays. Rennou™ Varnish is only applied by a professional clinician.

    Rennou™ Varnish is a topically applied flavored (Spearmint, etc.) compound comprised of natural rosin, ethanol, xylitol, and Rennou™ (a combination of theobromine, calcium acetate, and sodium hydrogen phosphate). The major components are rosin and ethanol, which, when delivered together, efficiently promote a fast-drying film on the tooth surface. The varnish is sweetened with xylitol.

    AI/ML Overview

    The provided document is an FDA 510(k) clearance letter for Rennou™ Varnish. This document focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study proving the device meets specific performance acceptance criteria in a quantitative manner typical of an AI/software device.

    A 510(k) submission primarily shows that a new device is as safe and effective as a legally marketed predicate device. While "testing summary" is mentioned, it refers to laboratory studies, not a clinical trial with human subjects and specific performance metrics like sensitivity, specificity, or accuracy compared to ground truth.

    Therefore, many of the requested elements for an AI/software device performance study are not applicable or cannot be extracted from this document, as Rennou™ Varnish is a physical medical device (cavity varnish), not an AI/software device.

    Here's an analysis based on the information provided, highlighting the differences:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not specify quantitative "acceptance criteria" in the way an AI/software device would (e.g., minimum sensitivity of 90%). Instead, the "acceptance criteria" are implicitly met by demonstrating substantial equivalence to the predicate device in terms of:

    Acceptance Criterion (Implicit)Reported Device Performance
    Premarket Notification (510(k)) Criteria
    Identity: Be substantially equivalent in indications for use, technological characteristics, and safety and effectiveness.Concluded to be substantially equivalent to predicate device: Colgate® Prevident Varnish (K132109).
    Similar Indications for UseRennou™ Varnish indicated for "relief of tooth hypersensitivity through the mechanical occlusion of dentinal tubules." This is consistent with the primary predicate and reference devices.
    Similar Product DesignCavity varnish product design is the same as the primary predicate device.
    Similar Technological CharacteristicsProvides prolonged contact of ingredients with tooth surface; forms protective barrier; releases minerals to enhance tooth structure. Biocompatible. Consistent with primary predicate and other reference devices.
    Safety - BiocompatibilityCytotoxicity testing per ISO 10993-5 and USP showed acceptable biocompatibility. Exhibited a slightly more favorable safety profile than the primary predicate.
    Effectiveness - Tubule Occlusion & Enamel ProtectionEnamel protection and dentinal hypersensitivity tests on molars and dentin specimens showed effective tubule occlusion, deep penetration, and a smooth surface finish, confirmed by SEM analysis.
    Risk AnalysisComprehensive risk analysis revealed no new questions of safety or effectiveness.

    2. Sample Size for Test Set and Data Provenance

    This information is not provided in the document. The "tests" mentioned are general laboratory studies ("Comprehensive laboratory studies evaluated Rennou™ Varnish for performance and biocompatibility. Enamel protection and dentinal hypersensitivity tests on molars and dentin specimens..."). There is no mention of a "test set" in the context of an AI/software device's performance evaluation against a defined ground truth.

    3. Number of Experts and Qualifications for Ground Truth

    Not applicable. This device is a physical product, not an AI/software diagnostic or assistive tool where expert-established ground truth is typically used for performance evaluation.

    4. Adjudication Method

    Not applicable for a physical device.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    Not applicable. This is not an AI/software device designed to assist human readers.

    6. Standalone (Algorithm Only) Performance Study

    Not applicable. This is a physical product, not an algorithm. The laboratory studies focused on the physical properties and biological interactions of the varnish itself.

    7. Type of Ground Truth Used

    For the laboratory studies:

    • Physical/Biological Measurements: SEM analysis for tubule occlusion, deep penetration, smooth surface finish.
    • Biocompatibility Standards: ISO 10993-5 and USP for cytotoxicity.
      These are objective measurements and established standards, rather than "ground truth" derived from expert consensus or pathology in the context of diagnostic AI.

    8. Sample Size for Training Set

    Not applicable for a physical medical device. There is no "training set" in the context of machine learning.

    9. How Ground Truth for Training Set Was Established

    Not applicable.

    Intended Use

    To relieve dental hypersensitivity caused by bleaching procedures, cold, heat, acids, or sweets.

    Device Description

    ReminGel is a convenient, premixed, ready-to-use, opaque aqueous-based gel. ReminGel consists of suspended hydroxyapatite and calcium and phosphate salts that help restore a tooth's hydroxyapatite structure through remineralization. This remineralization results in tubule occlusion and blocks fluid flow in dentinal tubules, thereby relieving dentinal sensitivity. ReminGel blocks nerve excitability through potassium release. ReminGel is packaged in a 3oz (90mL) tube. ReminGel is for prescription use (Rx) and over-the-counter (OTC) use. ReminGel can be applied to teeth using dental appliances (e.g. fluoride tray, whitening tray, periotray, etc.) or via a toothbrush.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and study information for ReminGel, based on the provided FDA 510(k) summary:

    Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (Anticipated Performance)Reported Device Performance (ReminGel)
    Tubule Occlusion: Visibly occlude dentinal tubules to inhibit dentin sensitivity.Visibly occluded dentinal tubules, demonstrating inhibition of dentin sensitivity. (Identical to predicate device Super Seal)
    Shelf-Life: Minimum of 2 years.2 years (determined through accelerated shelf-life testing; real-time aging ongoing).
    Transit Performance: Withstand simulated transit conditions.Performed satisfactorily post-transit, confirming no negative effect on the product.
    Cytotoxicity: Demonstrate acceptable levels of biocompatibility.Yielded better cytotoxicity results compared to the predicate device, SuperSeal.
    Irritation: Be a non-irritant.Found to be a non-irritant.
    Sensitization: Be a non-sensitizing agent.Found to be a non-sensitizing agent.

    Study Details

    1. Sample Size used for the test set and data provenance:

      • Tubule Occlusion Testing: Resected human teeth were used. The exact sample size ("N") is not specified.
      • Biocompatibility Testing (Cytotoxicity, Irritation, Sensitization): Not specified in terms of human subjects or teeth. These are in vitro and in vivo tests, typically performed on cell cultures or animal models for initial screening (as per ISO 10993 standards listed). The document does not provide details on the specific samples used for these tests.
      • Shelf-Life Testing: Not specified.
      • Transit Testing: Not specified.
      • Data Provenance: Not explicitly stated, but based on the in vitro nature of the tubule occlusion study on "resected human teeth," it implies laboratory testing rather than a clinical trial in patients. The biocompatibility tests are also laboratory-based. It is retrospective in the sense that the results were gathered and submitted as part of the 510(k) submission, not a prospective clinical trial.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • Not applicable/Not specified. The studies cited are non-clinical (laboratory/bench testing). For tubule occlusion, the "ground truth" would be the visible occlusion as observed through microscopy, which doesn't directly involve multiple expert adjudicators for "truth" establishment in the way clinical images would.
    3. Adjudication method for the test set:

      • Not applicable. As the studies are non-clinical, there is no expert adjudication method like 2+1 or 3+1 typically used for clinical image interpretation.
    4. 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 MRMC study was conducted. This device (ReminGel) is a medical product (cavity varnish) and not an AI/software-as-a-medical-device that would typically involve human readers and AI assistance for interpretation.
    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Not applicable. This is not an algorithm or AI device.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

      • Tubule Occlusion: Visual observation of dentinal tubule occlusion (likely microscopic evaluation).
      • Shelf-Life: Measured physical and chemical properties over time.
      • Transit, Cytotoxicity, Irritation, Sensitization: Results from standardized laboratory test methods (e.g., ISO 10993 series).
    7. The sample size for the training set:

      • Not applicable. This is a medical product, not a machine learning/AI model that requires a training set.
    8. How the ground truth for the training set was established:

      • Not applicable, as there is no training set for this type of device.

    Overall Context: The 510(k) summary focuses on demonstrating substantial equivalence to a predicate device (Super Seal) and a reference device (Senzzzz Away) through non-clinical performance and biocompatibility testing, rather than extensive clinical efficacy trials. Clinical performance was explicitly "not deemed necessary" for this submission, likely due to the established mechanism of action and similarity to legally marketed devices.

    Intended Use

    Indicated for relief of discomfort from dentin sensitivity.

    Device Description

    CrystLCare™ PRO Biorestorative, Fluoride-Plus is a flavored dental strip which contains calcium, phosphate, and fluoride which are stabilized with a modified starch. The single-use strip is topically applied to the outer surface of a tooth or teeth that are experiencing dental sensitivity. The strip dissolves in salivator elease these minerals which then will precipitate crystals that form a layer over the tooth surfaces. This physically occludes exposed dentinal tubules and enamel porosities to relieve discomfort. The modified starch helps to stabilize the calcium, phosphate, and fluoride mineral components so that they can persity into the dentinal tubules.

    AI/ML Overview

    Here's an analysis of the provided text regarding the acceptance criteria and study for the CrystLCare™ PRO Biorestorative, Fluoride-Plus device.

    Observation: The provided text is a 510(k) summary for a medical device (CrystLCare™ PRO Biorestorative, Fluoride-Plus) and does not describe acceptance criteria for a study that proves the device meets those criteria. Instead, it describes non-clinical tests used to demonstrate substantial equivalence to a predicate device, which is the basis for 510(k) clearance.

    The typical structure of a 510(k) submission means that detailed acceptance criteria and study methodologies, as one might find in a clinical trial report, are usually not fully disclosed in this summary document. The information provided focuses on demonstrating equivalence to an existing device rather than establishing new performance criteria.

    Therefore, I will extract the information that is present and note where the specific details requested are not available in this document.


    1. Table of Acceptance Criteria and Reported Device Performance

    Based on the provided text, specific numerical acceptance criteria (e.g., target occlusion percentage) are not explicitly stated for the non-clinical tests. Instead, the performance is described in terms of equivalence to the predicate device.

    Acceptance Criteria (Inferred from Substantial Equivalence Claim)Reported Device Performance (CrystLCare™ PRO Biorestorative, Fluoride-Plus)
    Occlusion of Dentinal Tubules: Should show similar occlusion of dentinal tubules and enamel porosities as the predicate device.Occlusion of Dentinal Tubules: Scanning Electron Micrographs (SEMs) of dentin samples treated by CrystLCare™ PRO were compared to SEMs of dentin treated with Relief© ACP Oral Care gel (predicate). The micrographs showed similar occlusion of the dentinal tubule. Occlusion was achieved by the deposition of a fluorohyapatite layer onto the surface of the tooth.
    Fluoride Release: While not a strict "acceptance criteria" for equivalence, the release should be safe and effective.Fluoride Release: Determined that fluoride exposure from CrystLCare™ PRO was lower than the predicate device, but "questions of safety or effectiveness are not raised." This implies the lower release is still considered sufficient and safe.
    Formation of Fluorohydroxyapatite Layer: Should form a similar layer.Formation of Fluorohydroxyapatite Layer: Demonstrated by Electron Dispersive X-ray (EDX) spectroscopy and X-Ray Diffraction (XRD) analysis, confirming the deposition of a fluorohyapatite layer.
    Biocompatibility: Should be biocompatible.Biocompatibility: Biocompatibility testing demonstrated that the device is as safe and effective as the predicate device.

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

    • Test Set (Non-clinical):
      • Sample Size: Not explicitly stated. The text mentions "dentin samples" and "micrographs of dentin samples." The exact number of samples or experimental replicates is not provided in this summary.
      • Data Provenance: Not specified. This was a non-clinical, in-vitro study.

    3. Number of Experts Used to Establish Ground Truth and Qualifications

    • Ground Truth for Non-Clinical Tests: Given that the study involves Scanning Electron Microscopy, EDX, and XRD analysis, the "ground truth" would be established by the results of these analytical techniques, interpreted by experts in materials science, microscopy, and potentially dentistry.
      • Number of Experts: Not specified. It's likely that internal experts or contracted lab personnel conducted and interpreted these analyses.
      • Qualifications of Experts: Not specified.

    4. Adjudication Method for the Test Set

    • Adjudication Method: Not applicable/not specified. For non-clinical, analytical studies like SEM, EDX, and XRD, interpretation relies on the technical expert performing and validating the analysis, rather than a consensus-based adjudication method typical of human-reader studies for medical imaging.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    • Was an MRMC study done? No.
    • Effect size of human readers with/without AI assistance: Not applicable. This device is a dental product (cavity varnish), not an AI-powered diagnostic imaging tool.

    6. Standalone (Algorithm Only) Performance Study

    • Was a standalone study done? Not applicable. This is a physical dental device, not an algorithm or software. The "performance" described is the device's physical and chemical action (occlusion, mineral deposition).

    7. Type of Ground Truth Used

    • Ground Truth: For the non-clinical tests, the ground truth was established by:
      • Analytical Results: Direct observation via Scanning Electron Micrographs (SEM) for physical occlusion, and elemental/structural analysis via Electron Dispersive X-ray (EDX) and X-Ray Diffraction (XRD) for chemical composition and crystal formation.
      • Comparison to Predicate: The performance was assessed relative to a legally marketed predicate device, with the predicate's established performance serving as a benchmark for equivalence.

    8. Sample Size for the Training Set

    • Training Set Sample Size: Not applicable. This device is a material science product; there is no "training set" in the context of machine learning or AI.

    9. How Ground Truth for Training Set Was Established

    • Ground Truth for Training Set: Not applicable, as there is no training set.

    Intended Use

    Jasmate® Toothpaste is prescription fluoride dentifrice for use in the prevention and treatment of dental sensitivity.

    Device Description

    Jasmate® toothpaste is a dentist and dental professional prescribed, daily-use, fluoride dentifrice to be used in the prevention and treatment of dental sensitivity through the physical occlusion of dentin tubules.

    Sodium fluoride is absorbed by the surface of hydroxyapatite crystals on the teeth, which are needed for mineralization. This makes the teeth more resistant to demineralization by changing the apatite crystal solubility. Sodium fluoride inhibits the demineralization of teeth in a pH-related manner. Sodium fluoride and hydroxyapatite are active ingredients. When exposed environment, it undergoes a rapid surface reaction to form fluorapatite, which is chemically and structurally similar to natural tooth mineral, allowing it to physically occlude tubules.

    AI/ML Overview

    The provided text is a 510(k) Premarket Notification from the FDA for a new medical device, Jasmate® Toothpaste. It details the device's characteristics, intended use, and a comparison to a predicate device (BioMinF® Toothpaste) to establish substantial equivalence.

    However, the document does not contain information about acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML algorithm or software. The tests mentioned are for a physical product (toothpaste) and evaluate properties like density, pH, viscosity, spreadability, foaming power, relative dentin abrasion, enamel fluoride uptake, enamel solubility reduction, and tubule occlusion (via SEM). These are standard physical and chemical performance tests for a dentifrice, not evaluation of an AI system.

    Therefore, I cannot fulfill the request as it pertains to AI/ML acceptance criteria and studies, because the provided input does not describe such a device or its evaluation. The request's template is designed for AI/ML product submissions, while the document describes a chemical/physical product.

    Intended Use

    Profisil® Fluoride Varnish is a 5 % sodium fluoride varnish which produces mechanical occlusion of the dentinal tubules in the treatment of tooth hypersensitivity.

    Device Description

    Profisil® Fluoride Varnish is designed to securely adhere to the tooth surface for several hours while releasing fluoride ions. The varnish contains 5 % sodium fluoride suspended in a mucosa-friendly, pleasantly flavored dimethicone gel. The varnish is available in following versions: mint, berry and unflavored.

    AI/ML Overview

    The provided document describes a 510(k) premarket notification for a dental device, "Profisil Fluoride Varnish." This type of submission relies on demonstrating substantial equivalence to a legally marketed predicate device, rather than conducting new clinical trials for effectiveness. Therefore, the information typically requested about acceptance criteria and studies proving a device meets them for new effectiveness claims, especially those involving AI or comparative effectiveness with human readers, is not directly applicable to this specific submission.

    However, the document does detail how the new device demonstrates equivalence to its predicate, focusing on non-clinical performance and biocompatibility. Here's a breakdown of the relevant information provided:

    1. Table of Acceptance Criteria and Reported Device Performance

    For "Profisil® Fluoride Varnish," the acceptance criteria for non-clinical performance are based on the international standard EN ISO 17730:2020 "Dentistry - fluoride varnishes."

    Performance CharacteristicAcceptance Criteria (EN ISO 17730:2020)Reported Device Performance (Profisil® Fluoride Varnish)Conclusion

    PyrogenicityISO 10993-11Meets ISO 10993-11 requirementsMet requirements
    Systemic toxicityISO 10993-11Meets ISO 10993-11 requirementsMet requirements

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

    • Test set sample size: Not explicitly stated as this is a non-clinical device evaluation. The "test set" would refer to the samples of the Profisil® Fluoride Varnish subjected to the various physical and chemical tests (e.g., specific batches for pH, viscosity, fluoride release tests) and biocompatibility studies (e.g., cell cultures for cytotoxicity, animal models for sensitization/irritation). The exact number of samples tested for each property is not detailed in the summary.
    • Data provenance: The standard EN ISO 17730:2020 is an international standard. Biocompatibility standards like ISO 10993 series are also international. The summary indicates these tests were performed to demonstrate compliance with these standards, suggesting laboratory testing specifically for the Profisil® product. There is no information on country of origin of data beyond the manufacturer being based in Germany. The data is prospective as it was generated to support the current submission.

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

    This information is not applicable. The "ground truth" for this type of device comparison is based on established scientific and engineering principles codified in international standards (EN ISO 17730:2020 for dental fluoride varnishes) and biocompatibility standards (ISO 10993 series). The results are objectively measured physical and chemical properties and biological responses, not subjective interpretations by human experts in the sense of medical image analysis.

    4. Adjudication Method for the Test Set

    Not applicable, as the "test set" involves objective laboratory measurements against predefined standard requirements rather than subjective assessments requiring adjudication.

    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

    Not applicable. This device is a dental fluoride varnish, not an AI-powered diagnostic or assistive tool. Therefore, MRMC studies are irrelevant to this submission.

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

    Not applicable for the same reason as above; this is a physical dental material, not an algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for the current device's performance evaluation is based on International Standards:

    • EN ISO 17730:2020 "Dentistry - fluoride varnishes" for physical and chemical properties (pH, dynamic viscosity, fluoride release, SEM).
    • ISO 10993 series for biocompatibility studies (cytotoxicity, sensitization, irritation, pyrogenicity, systemic toxicity).

    These standards define the acceptable range or nature of results for these properties, which serve as the objective "ground truth" for evaluation.

    8. The Sample Size for the Training Set

    Not applicable. This device is not an AI algorithm and therefore does not have a "training set."

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

    Not applicable.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for a medical device called "3M™ Clinpro™ Clear 2.1% Sodium Fluoride Treatment." This type of submission focuses on demonstrating substantial equivalence to a predicate device, rather than conducting a full clinical trial to prove efficacy and safety through detailed acceptance criteria and studies as one might see for novel high-risk devices.

    Therefore, the information typically available for a detailed acceptance criteria and performance study (as requested in the prompt) such as prospective studies, ground truth establishment by multiple experts with adjudication, MRMC studies, or standalone algorithm performance, is not present in this type of FDA submission.

    Instead, the document details bench testing to demonstrate that the subject device performs similarly to or better than its predicate devices based on certain physical properties and release characteristics. The acceptance criteria here are mainly "Pass/Fail" based on whether the device meets specific thresholds or shows comparable performance to the predicate devices in these bench tests.

    Here's an attempt to extract and present the available information in the requested format, with the understanding that many aspects of your request (e.g., human-in-the-loop studies, multi-reader studies, detailed expert ground truth, training set information) are not applicable or not provided in a 510(k) submission for a dental varnish.


    Acceptance Criteria and Device Performance Study for 3M™ Clinpro™ Clear 2.1% Sodium Fluoride Treatment

    Note: This 510(k) submission primarily relies on demonstrating substantial equivalence through bench testing against predicate devices, rather than clinical efficacy studies with human subjects. Therefore, many of the requested details, particularly those related to human reader studies, multi-expert ground truth establishment, and training/test set specifics for AI/ML models, are not applicable or not provided in this type of regulatory document for a tooth varnish. The "acceptance criteria" here refer to the performance thresholds set for the bench tests.

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

    The document does not specify a "test set" in the context of patient data or clinical images, as the evaluation is based on in-vitro bench testing of the device material. The sample size for each bench test (e.g., number of replicates, number of specimens) is typically detailed in the internal test reports, but not provided in this summary. The data provenance is from laboratory bench testing conducted by 3M, not from specific patient populations or countries.

    3. Number of Experts Used to Establish Ground Truth and Qualifications

    Not applicable. The "ground truth" for this device's performance is established by standardized laboratory testing methods and physical measurements, not by human expert interpretation of clinical data or images.

    4. Adjudication Method for the Test Set

    Not applicable. As the "test set" is material performance data from laboratory tests, no adjudication method is required.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

    No. This type of study (comparing human readers with and without AI assistance) is not applicable to a dental varnish product. This device is not an imaging AI or diagnostic tool.

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

    Not applicable. This device is a physical product (dental varnish), not an algorithm or software. Its performance is evaluated through material science and physical property tests.

    7. The Type of Ground Truth Used

    The ground truth used is based on physical and chemical measurements and observations from in-vitro laboratory bench tests, conforming to established standards (e.g., ISO 17730-2020) or validated internal methods. For example, "visually occlude exposed dentin tubules" for SEM, or measurable fluoride release values.

    8. The Sample Size for the Training Set

    Not applicable. This device is a physical product, not a machine learning model, so there is no "training set" in the context of data for model development.

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

    Not applicable. See point 8.

    Intended Use

    APAPRO Desensitizer is a fluoride-free paste that is indicated to provide relief from tooth hypersensitivity resulting from cold, heat, acids, sweets, or contact, through its action of dentin tubule occlusion.

    Device Description

    APAPRO Desensitizer is a fluoride-free tooth desensitizing paste that utilizes hydroxyapatite, the main component of teeth, as its active ingredient to relieve tooth sensitivity by physically occluding exposed dentin tubules. The hydroxyapatite deposited into dentin tubules by APAPRO Desensitizer then acts as a template for the further deposition of large amounts of calcium and phosphate ions, promoting crystal integrity and growth.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for a dental device, Apapro Desensitizer. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than conducting a full clinical study with specific acceptance criteria related to a new device's performance metrics like sensitivity and specificity.

    Therefore, the information requested about acceptance criteria, study details, sample sizes, expert involvement, adjudication methods, MRMC studies, standalone performance, and ground truth establishment is not available within the provided text.

    The submission for Apapro Desensitizer (K220419) primarily relies on non-clinical tests comparing its mechanism of action and effectiveness in occluding dentin tubules to a predicate device, Oralief™ Therapy for Sensitive Teeth (K040858).

    Here's what can be extracted based on your request, even if it highlights what's missing:

    1. Table of acceptance criteria and the reported device performance:

      • Acceptance Criteria: Not explicitly stated as quantifiable performance metrics (e.g., specific percentages for sensitivity, specificity, or accuracy) in the context of a clinical trial. The "acceptance criteria" here implicitly refer to demonstrating substantial equivalence to the predicate device based on technological characteristics, intended use, indications for use, and a similar mechanism of action.
      • Reported Device Performance: The primary reported "performance" is that "APAPRO Desensitizer was shown to be as effective as the NovaMin® found in the predicate device in occluding dentin tubules."
      TraitAcceptance Criteria (Implicit for Substantial Equivalence)Reported Device Performance (APAPRO Desensitizer)
      Indications for UseMust be equivalent to the predicate device: Provides relief from tooth hypersensitivity resulting from cold, heat, acids, sweets, or contact, through its action of dentin tubule occlusion.Provides relief from tooth hypersensitivity resulting from cold, heat, acids, sweets, or contact, through its action of dentin tubule occlusion. (Equivalent)
      Intended UseMust be equivalent to the predicate device: For dental hypersensitivity relief, prescribed and applied by dental physicians for use in the Adult Population.For dental hypersensitivity relief, prescribed and applied by dental physicians for use in the Adult Population. (Equivalent)
      Mechanism of ActionMust be equivalent or substantially similar to the predicate device: Formation of a hydroxyapatite layer to physically occlude dentin tubules.Directly occludes dentin tubules by depositing a crystalline calcium phosphate layer (hydroxyapatite) on the tooth surface. (Equivalent in outcome, though different in active ingredient origin. Details in "Active Ingredient" and "Material Produced to Occlude Tubules").
      Performance (Dentin Tubule Occlusion)Must demonstrate comparable effectiveness in occluding dentin tubules to the predicate device.SEM micrographs showed similar occlusion of dentin tubules as NovaMin-treated samples. "APAPRO Desensitizer was shown to be as effective as the NovaMin® found in the predicate device in occluding dentin tubules."
      BiocompatibilityMust be biocompatible and non-antigenic, conforming to ISO 10993 standards.Biocompatible, non-antigenic. Biocompatibility tests in accordance with ISO 10993 performed, and a biological risk assessment indicates no hazardous effects when used as directed in the Adult Population. (Equivalent)
    2. Sample sizes used for the test set and the data provenance:

      • Sample Size: Not specified. The "test set" in this context refers to dentin samples used for SEM imaging, not human subjects in a clinical trial.
      • Data Provenance: Not specified (e.g., country of origin, retrospective/prospective). The study was a "non-clinical test" involving dentin samples.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • Not applicable as this was a non-clinical in vitro test using SEM micrographs, not a study requiring expert clinical interpretation for ground truth.
    4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

      • Not applicable. This was an in vitro comparison of SEM micrographs, not a human reader study.
    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, an MRMC comparative effectiveness study was not done. This device is not an AI-based diagnostic tool.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Not applicable. This is a material-based dental desensitizer, not an algorithm.
    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

      • For the non-clinical test, the "ground truth" for demonstrating dentin tubule occlusion was established through Scanning Electron Microscopy (SEM) micrographs to visually confirm the physical occlusion by the deposited hydroxyapatite layer. This is an objective laboratory measure.
    8. The sample size for the training set:

      • Not applicable. There is no mention of a "training set" as this device is not an AI algorithm.
    9. How the ground truth for the training set was established:

      • Not applicable. There is no training set mentioned.
