    Device Description

    Quantium is a light-cured, radiopaque, universal composite. Quantium is designed to blend with the tooth structure when used alone or in the layering technique.

    AI/ML Overview

    The provided FDA 510(k) summary for the Quantium device (K242816) does not contain information typically associated with AI/ML device evaluations, such as specific acceptance criteria related to accuracy, sensitivity, specificity, or studies involving human readers or ground truth established by experts.

    Instead, this document focuses on the nonclinical testing of a dental composite resin material against a predicate device and relevant ISO standards. Therefore, many of the standard questions regarding AI/ML device studies are not applicable.

    Here's an analysis based on the provided text:

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

    The document states that nonclinical testing of Quantium and the predicate device was selected from the "FDA Guidance Document, Dental Composite Resin Devices - Premarket Notification [510(k)] Submissions - Guidance for Industry and FDA Staff, issued October 2005." The tests were conducted according to ISO 4049:2019.

    Acceptance Criteria (Implied by adherence to ISO 4049:2019 and comparison to predicate):
    The acceptance criteria are implicitly that Quantium must meet or exceed the requirements set forth in ISO 4049:2019 for the tested properties and perform equal to or better than the predicate device (TrusFIL Universal Composite Restorative, K202063).

    Reported Device Performance:
    "The nonclinical tests performed on Quantium and the predicate device showed Quantium performed equal to or better than the predicate. In addition, both devices meet the requirements set forth in ISO 4049:2019."

    Test ParameterAcceptance CriteriaQuantium Performance

    Compressive strengthComparable to PredicatePerformed equal to or better than predicate
    Flexural modulusComparable to PredicatePerformed equal to or better than predicate
    Hardness after cureComparable to PredicatePerformed equal to or better than predicate

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

    The document describes nonclinical testing of material properties, not a clinical study involving patients or human data. Therefore, the concept of a "test set" and "data provenance" in the context of patient data is not applicable here. The sample sizes for each specific material test (e.g., number of specimens for flexural strength) are not detailed in this summary document. These details would typically be found in the full test reports, which are not provided.

    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. This is a nonclinical material science study, not an AI/ML clinical study requiring expert ground truth for interpretation.

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

    Not applicable, as this is a nonclinical material science 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. This is a nonclinical material science study.

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

    No. This is a nonclinical material science study, not an AI/ML device.

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

    The "ground truth" for this device is established by physical and chemical measurements conforming to ISO 4049:2019 standards and direct comparison to a legally marketed predicate device. This is a material science "ground truth," not a clinical ground truth.

    8. The sample size for the training set

    Not applicable. This is a nonclinical material science device, not an AI/ML device that requires a training set.

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

    Not applicable.

    Device Description

    TheraBase and TheraBase Ca are a self-etching, self-adhesive, dual-cured resin luting cement and base/liner that is exclusively formulated for luting crowns, bridges, inlays, onlays and posts (prefabricated metal and non-metal/fiber posts, as well as cast posts) and basing/lining under restorations. TheraBase is a paste/paste, fluoride- and calcium-releasing, luting cement and base/liner which requires no etching, no priming or bonding of the prepared surfaces. TheraBase Ca is a paste/paste, calcium-releasing, luting cement and base/liner which requires no etching, no priming or bonding of the prepared surfaces. They are easy-to use, require only a short chair time, and produce a good bond to most dental materials. The cements are available in a Natural shade. They are radiopaque, allowing for easy identification on radiographs.

    AI/ML Overview

    The document you provided is a 510(k) summary for a dental device, TheraBase / TheraBase Ca. This type of document is a premarket notification to the FDA to demonstrate that the device is substantially equivalent to a legally marketed predicate device.

    Crucially, this document does not describe a study that proves the device meets specific acceptance criteria in the context of an AI/ML algorithm or a comparative effectiveness study with human readers.

    Instead, it presents performance data for the physical and mechanical properties of the dental cement, comparing them to established ISO standards or internal benchmarks.

    Therefore, I cannot fulfill all parts of your request as it pertains to an AI/ML device with ground truth, expert adjudication, or MRMC studies. However, I can extract the relevant information regarding the device's physical and mechanical properties and present it in your requested format.

    Here's the breakdown based on the provided document:

    Regarding the AI/ML specific questions:

    1. Sample size used for the test set and the data provenance: Not applicable. This document describes physical material testing, not an AI/ML algorithm's performance on a test set of data.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Material properties are measured objectively according to standard protocols (e.g., ISO standards), not by expert consensus on data.
    3. Adjudication method: Not applicable.
    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: Not applicable. This is a dental cement, not an AI assistant for human readers.
    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
    6. The type of ground truth used: Not applicable in the context of AI/ML. The "ground truth" for the material properties are the objective measurements obtained through standardized physical and chemical tests (e.g., ISO standards for film thickness, flexural strength, radiopacity).
    7. The sample size for the training set: Not applicable. This document refers to a physical product, not a machine learning model.
    8. How the ground truth for the training set was established: Not applicable.

    Summary of the study that proves the device meets the acceptance criteria (based on the document):

    The device's performance was evaluated through a series of physical and mechanical property tests. These tests were conducted according to established industry standards such as ISO 29022 (modified), ISO 4049:2009, and the Gel-Cap method for bond strength. The document also mentions a Biocompatibility evaluation conducted using ISO 7405:2008 and ISO 10993-1, including an Oral Toxicity Study (10 mice, 14 days) which found the materials non-toxic.

    The studies collectively demonstrated that both TheraBase and TheraBase Ca met or exceeded the specified acceptance criteria for each tested property (bond strength, diametral tensile strength, film thickness, flexural strength, radiopacity, working/setting time, compressive strength, calcium release, and fluoride release for TheraBase). The conclusion is that the devices are substantially equivalent to the predicate devices based on these chemical composition characteristics, biocompatibility, and physical properties.

    AI/ML Overview

    This document is a 510(k) summary for TheraCal DC, a dental restorative material. The purpose of a 510(k) is to demonstrate that a medical device is substantially equivalent to a legally marketed predicate device. This document does not describe a study involving an AI-powered diagnostic device, but rather a dental material. Therefore, many of the requested categories for AI device studies are not applicable.

    Here's an attempt to extract relevant information and note the inapplicable categories:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document compares the "Modified TheraCal DC" (the subject device) to the "TheraCal DC (K143292)" (the predicate device). The acceptance criteria are essentially that the modified device performs equivalently to the predicate in key physical and mechanical properties.

    Characteristic / PropertyAcceptance CriteriaSubject Device Performance (Modified TheraCal DC)

    Physical/Mechanical PropertiesEquivalent performance to predicate in: Flexural strength, Compressive strength, Dimetral tensile strength, Working time, Bond strength, Radiopacity, Water sorption and solubility, Calcium release, pH.Direct comparison testing demonstrates that TheraCal DC is equivalent to the predicate device. (Specific values not provided in this summary, but implied to meet equivalence.)
    BiocompatibilityMeets requirements of ISO 7405:2008 and ISO 10993-1:2009An evaluation was conducted using these standards, and it is concluded that TheraCal DC meets the requirements of the testing.

    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: Not specified. The document states "direct comparison testing" and "evaluated" for physical/mechanical properties and biocompatibility, but the exact sample sizes for each test are not listed in this summary.
    • Data provenance: Not specified, but standard ISO/ANSI/ADA test methods are referenced, implying laboratory testing. The company, Bisco, Inc., is based in Schaumburg, Illinois, USA. The testing would presumably have been conducted in a lab environment. The study is prospective in the sense that the testing was performed specifically to support this 510(k) application for the modified device.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    Not applicable. This is a material science study, not a clinical study requiring expert interpretation of results. The "ground truth" is established by adherence to recognized international and national standards for material testing (e.g., ISO 4049, ANSI/ADA Spec. No. 27, ISO 7405, ISO 10993).

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

    Not applicable. This is not a study requiring adjudication of 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

    Not applicable. This is not an AI diagnostic device.

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

    Not applicable. This is not an AI diagnostic device.

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

    The "ground truth" for the material's properties is defined by objective physical and mechanical measurements according to established international and national standards (e.g., ISO 4049:2009 for flexural strength and radiopacity, ANSI/ADA Spec. No. 27:1993 for compressive strength, ISO 7405:2008 and ISO 10993-1:2009 for biocompatibility).

    8. The sample size for the training set

    AI/ML Overview

    The provided document is a 510(k) summary for a dental restorative material called REVEAL Bulk. It does not describe a study involving an AI device or a comparative effectiveness study with human readers. Instead, it focuses on demonstrating substantial equivalence of REVEAL Bulk to an existing predicate device based on physical, mechanical, and biocompatibility properties.

    Therefore, many of the requested categories for AI device studies, such as sample sizes for test sets, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone algorithm performance, and training set details, are not applicable to this document.

    However, I can extract the relevant information regarding the acceptance criteria and performance of the REVEAL Bulk device for its intended use as a dental restorative material.

    2. Sample size used for the test set and the data provenance:

    • The document does not specify the exact sample sizes (number of specimens) used for each physical/mechanical test.
    • The data provenance is from laboratory testing conducted by Bisco, Inc. (the applicant) on their REVEAL Bulk device. The standards referenced (e.g., ISO 4049:2009, ISO 7405:2008, ISO 10993-1) are international standards for dental materials and biocompatibility.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • This question is not applicable as the "ground truth" for this medical device submission relies on established international standards (e.g., ISO for physical properties) and scientific principles for material characterization, rather than human expert consensus on diagnostic images or clinical outcomes. The performance is measured against these objective standards and comparison to a legally marketed predicate device.

    4. Adjudication method for the test set:

    • This question is not applicable as there is no human interpretation or adjudication involved in the objective physical and mechanical property testing of a dental restorative material. The results are quantitative measurements against defined criteria.

    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 question is not applicable. The submission is for a dental restorative material, not an AI device. No MRMC study was conducted.

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

    • This question is not applicable. The submission is for a dental restorative material, not an AI algorithm.

    7. The type of ground truth used:

    • The "ground truth" for this device's performance is based on established international standards and predicate device performance. For example:
      • ISO 4049:2009 for polymer-based restorative materials, specifying test methods and requirements for properties like flexural strength, radiopacity, water sorption, solubility, and depth of cure.
      • ISO 7405:2008 and ISO 10993-1 for biological evaluation of medical devices (biocompatibility).
      • Equivalence to a legally marketed predicate device (Filtek Bulk Fill K141081) for other properties like diametral tensile strength, volumetric shrinkage, compressive strength, wear, polish retention, surface hardness, and cusp deflection.

    8. The sample size for the training set:

    • This question is not applicable. This is not an AI device or a machine learning model, so there is no "training set."

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

    • This question is not applicable. There is no training set for this type of device submission.

    Intended Use

    CeraClean is an extraoral cleaner of pre-treated ceramic, zirconia and metal restoration surfaces which have been contaminated during intraoral try-in.

    Device Description

    CeraClean is used outside the mouth, as an extraoral cleaning gel suitable for non-abrasive cleaning of the bonding surfaces of prosthetic restorations after intraoral try-in. CeraClean is applied through a single-use tip or application to the prosthetic restorations and rinsed off prior to the application of a primer or cement for final placement of the restoration.

    AI/ML Overview

    The provided text describes a 510(k) summary for the CeraClean device, which is an extraoral cleaner for dental restoration surfaces. The study presented aims to demonstrate substantial equivalence to a predicate device, Resolve 2.0.

    Here's an analysis of the acceptance criteria and the study that proves the device meets those criteria, based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document doesn't explicitly state "acceptance criteria" in a typical clinical study sense with quantitative thresholds for sensitivity, specificity, and so on. Instead, it focuses on demonstrating substantial equivalence to a predicate device based on technological characteristics and performance data. The implicit acceptance criterion is that CeraClean's performance must be "substantially equivalent" to that of the predicate device, Resolve 2.0, across various relevant parameters.

    Acceptance Criterion (Implicit: Substantial Equivalence to Predicate)Reported Device Performance (CeraClean)
    Indications for Use:
    - Extraoral cleaner for dental restorations.- Extraoral cleaner of pre-treated ceramic, zirconia, and metal restoration surfaces which have been contaminated during intraoral try-in. (Stated as substantially equivalent)
    Chemical Composition:
    - Water Solubility- Water Soluble (Explicitly stated as substantially equivalent to predicate)
    - pH after rinsing (Neutral)- pH = 7 (Predicate: pH = 7; Stated as substantially equivalent to predicate)
    Physical/Mechanical Properties:
    - Shear Bond Strength (removes saliva contamination)- Removes saliva contamination (Explicitly stated as substantially equivalent to predicate based on modified ISO 29022:2013)
    - Water Solubility- Water Soluble (Explicitly stated as substantially equivalent to predicate)
    - Method of application (Syringe tip w/brush)- Syringe tip or brush (Similar, within equivalence)
    - Method of removal (Water spray & air dried)- Water spray & air dried (Identical)
    - Removal from substrate (SEM EDX)- Demonstrates device is removed from substrate.
    Biocompatibility:
    - Meets biocompatibility requirements.- Met the requirements of the test (ISO 7405:2008 and ISO 10993-1:2009 cytotoxicity testing)

    Note on Differences: The document acknowledges differences in chemical composition (e.g., CeraClean is water-based gel with xanthum gum and potassium hydroxide vs. acrylate resin-based with silicate and chlorohexidine for Resolve 2.0; CeraClean is non-abrasive while Resolve 2.0 is abrasive). However, it argues these differences do not raise new questions of safety or effectiveness as both are water soluble, used outside the mouth, and rinsed off.

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

    The document does not explicitly state the sample size for the test set. For the shear bond strength test based on modified ISO 29022:2013, it implies that the device was tested, but the number of samples or cases is not provided. Similarly, for water solubility, pH, and SEM EDX, specific sample sizes are not mentioned.

    The data provenance is not specified. It's likely an in-house or contracted laboratory study, but the country of origin or whether it's retrospective or prospective data is not detailed. Given the nature of a 510(k) submission for a cleaning solution, this would typically involve laboratory testing rather than human subject data.

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

    This information is not provided in the document. For a product like CeraClean, "ground truth" might refer to analytical chemistry results or physical property measurements rather than expert interpretations of images or clinical outcomes. The document relies on established ISO standards (ISO 29022:2013 for bond strength, ISO 7405:2008 and ISO 10993-1:2009 for biocompatibility) for its performance claims, implying that adherence to these standards constitutes the "ground truth" of performance evaluation.

    4. Adjudication Method for the Test Set

    The document does not mention any adjudication method. Given that the tests are laboratory-based (shear bond strength, pH, water solubility, SEM EDX, biocompatibility), results would typically be quantitative and objectively measured, not requiring expert adjudication in the same way clinical imaging studies do.

    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 is relevant for diagnostic imaging devices where human interpretation is involved. CeraClean is an extraoral cleaning solution, and its performance is evaluated through material science and biocompatibility tests.

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

    The performance tests conducted (Shear Bond Strength, Water Solubility, pH, SEM EDX, Biocompatibility) are standalone laboratory tests of the device's physical and chemical properties. There is no "human-in-the-loop" component to these performance measurements as they assess the intrinsic properties and effectiveness of the cleaning solution itself.

    7. The Type of Ground Truth Used

    The "ground truth" for the performance evaluation appears to be based on:

    • Established material science standards and measurements: e.g., modified ISO 29022:2013 for shear bond strength, direct measurements for pH and water solubility, SEM EDX for residue removal.
    • Biocompatibility standards: ISO 7405:2008 and ISO 10993-1:2009.

    This is not expert consensus, pathology, or outcomes data in the clinical sense, but rather objective, repeatable measurements under controlled laboratory conditions referencing international standards.

    8. The Sample Size for the Training Set

    The concept of a "training set" is not applicable to this device or study design. Training sets are used in machine learning or AI algorithm development. CeraClean is a physical cleaning solution, not a software algorithm.

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

    As there is no training set, this question is not applicable.

    AI/ML Overview

    The provided text describes the acceptance criteria and performance of the "All-Bond Universal w/BAC" dental adhesive.

    Here's the information requested, extracted and organized:

    1. Table of Acceptance Criteria and Reported Device Performance

    Physical / Mechanical PropertyAcceptance Criteria (Implied by Equivalence to Predicates or ISO Standard)Reported Device Performance (All-Bond Universal w/BAC)
    Bond StrengthEquivalent to primary and reference predicates (DREAMBOND, Peak Universal Bond)Equivalent to the primary and reference predicate.
    Moisture ToleranceEquivalent to primary and reference predicates (DREAMBOND, Peak Universal Bond)Equivalent to the primary and reference predicate.
    Film ThicknessMeets requirements of ISO 4049:2009 (Predicate values: DREAMBOND: 2.6µm, Peak Universal Bond: 17.0µm)Meets the requirements of ISO 4049:2009 for Film Thickness. (Reported value: 3.4µm, shown in a separate table implying it meets the standard and is comparable to predicates).
    Water Sorption / SolubilityEquivalent to primary predicate (DREAMBOND) based on ADA/ANSI Specification No. 27Equivalent to the primary predicate.
    Immediate Bond StrengthEquivalent to primary and reference predicates (DREAMBOND, Peak Universal Bond)Equivalent to the primary and reference predicate.
    Bond Strength DurabilityPerformance comparable to or better than predicates (Reference predicate showed 23% reduction, Primary predicate showed 27% reduction)Showed a 4% increase in bond strength on completion of the test.
    Solvent EvaporationEquivalent to primary and reference predicates (DREAMBOND, Peak Universal Bond)Equivalent to the primary and reference predicate.
    pHEquivalent to primary predicate (DREAMBOND)Equivalent to the primary predicate.
    BiocompatibilityNot toxic (Implied standard based on ISO 7405:2008 and ISO 10993-1)Concluded from the evaluation and the results of the Oral Toxicity Study (10 rats, 7 days) that All-Bond Universal w/BAC was not toxic in this test.

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

    • Test Set Sample Size:
      • For Biocompatibility, an "Oral Toxicity Study" used 10 rats.
      • For other physical/mechanical properties (Bond Strength, Moisture Tolerance, Film Thickness, Water Sorption / Solubility, Immediate Bond Strength, Bond Strength Durability, Solvent Evaporation, pH), specific sample sizes are not explicitly stated in the provided text. The testing is described as occurring for "All-Bond Universal w/BAC".
    • Data Provenance: The text does not explicitly state the country of origin or whether the studies were retrospective or prospective. It is implied these are laboratory-based studies conducted by or for the manufacturer (Bisco, Inc. in Schaumburg, IL, USA) for regulatory submission.

    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)

    • The studies described are physical/mechanical property tests and biocompatibility tests, not studies requiring expert interpretation (like medical imaging). Therefore, there were no human experts establishing "ground truth" in the diagnostic sense. The "ground truth" is established by the standardized testing methodologies (e.g., ISO, ADA/ANSI standards) and measurements of physical properties.

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

    • This concept is not applicable here as the studies are laboratory-based physical and mechanical property tests and animal biocompatibility studies, not studies requiring human adjudication of subjective data. Therefore, none was used.

    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 MRMC comparative effectiveness study was done. This device is a dental adhesive, not an AI-powered diagnostic tool, so such a study would not be relevant.

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

    • This device is a dental adhesive, not an algorithm or AI system. Therefore, the concept of "standalone performance" for an algorithm is not applicable. The performance demonstrated is the standalone performance of the material itself.

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

    • The "ground truth" for the performance of the dental adhesive is based on standardized laboratory testing methods (e.g., modified ISO 29022:2013 for bond strength, ISO 4049:2009 for film thickness, ADA/ANSI Specification No. 27 for water sorption/solubility, and ISO 7405:2008 and ISO 10993-1 for biocompatibility). For biocompatibility, it was specifically an "Oral Toxicity Study" with animal models.

    8. The sample size for the training set

    • There is no training set mentioned or implied, as this is a physical product (dental adhesive), not a machine learning model.

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

    • As there is no training set, this question is not applicable.

TheraCem is a paste/paste, fluoride- and calciumreleasing, luting cement which requires no etching, no priming or bonding of the prepared surfaces. It is easy-to use, requires only a short chair time, and produces a good bond to most dental materials. The cement is available in a Natural shade. It is radiopaque, allowing for easy identification on radiographs.

    AI/ML Overview

    The provided text is a 510(k) summary for the dental cement TheraCem. It describes the device, its indications for use, technological characteristics, and performance data, but it does not contain the information you're looking for regarding acceptance criteria and study details for an AI/CADe device.

    Specifically, the document focuses on demonstrating substantial equivalence to predicate dental cements based on physical and mechanical properties, not on AI-assisted diagnostic or decision-making capabilities. Therefore, I cannot extract the following information from the provided text:

    1. A table of acceptance criteria and the reported device performance: The document provides a table of physical/mechanical properties tested for TheraCem and states its equivalence to predicates or compliance with ISO standards, but these are not "acceptance criteria" in the context of an AI device's diagnostic performance (e.g., sensitivity, specificity, AUC).
    2. Sample size used for the test set and the data provenance: Not applicable, as there's no diagnostic test set.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
    4. Adjudication method: Not applicable.
    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done: Not applicable.
    6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable.
    7. The type of ground truth used: For a dental cement, "ground truth" would relate to its physical properties (e.g., bond strength, setting time), which are measured according to established standards (e.g., ISO).
    8. The sample size for the training set: Not applicable, as there's no AI model being trained.
    9. How the ground truth for the training set was established: Not applicable.

    The document is for a medical device (dental cement) that does not involve AI or diagnostic imaging. The performance data presented is about the product's physical and chemical characteristics, which are compared to predicate devices for substantial equivalence.

    Orthodontic Acrylic intended for the fabrication of methacrylate-based orthodontic appliances (such as retainers, bite guards, and bite plates, etc.).

    Device Description

    Orthodontic Acrylic is a fast curing self-cure 2-part system. The system consists of a powder and a liquid. The combination of the powder and liquid is converted into a hard methacrylate finished product.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for an orthodontic acrylic device. It does not contain any information about an AI/ML powered device, a comparative effectiveness study, or details about ground truth establishment with experts. The document focuses on the substantial equivalence of the Orthodontic Acrylic to a predicate device based on chemical composition and physical/mechanical properties.

    Therefore, many of the requested sections regarding AI/ML powered devices, expert adjudication, and ground truth establishment cannot be answered from the provided text.

    Here's a breakdown of the information that can be extracted, acknowledging the limitations for AI/ML related questions:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document describes performance data in terms of physical/mechanical properties and biocompatibility. It does not explicitly state "acceptance criteria" with numerical targets, but rather mentions "meeting the requirements" or providing "similar" results to the predicate.

    Performance CharacteristicAcceptance Criteria (Implicit)Reported Device Performance
    Physical/Mechanical PropertiesDemonstrates similarity to the predicate device per ISO 20795-2:2010.Tested for flexural strength, flexural modulus, fracture toughness, water sorption, and water solubility. The information provided demonstrates that they are similar to the predicate. (Specific values are not provided in this summary but are referenced as being in the 510(k)).
    BiocompatibilityMeets requirements of ISO 7405:2008 and ISO 10993-1.Orthodontic Acrylic was tested for Guinea Pig Maximization Sensitization Testing and Oral Mucosal Irritation (ISO 10993-10) and cytotoxicity (ISO 10993-5); Orthodontic Acrylic met the requirements for these tests.
    In-vitro TestingNot explicitly stated as acceptance criteria.In-vitro testing was conducted on Candida albicans, Streptococcus mutans, and Actinomyces naselundii. (Results or specific criteria for these tests are not provided in this summary.)

    2. Sample size used for the test set and the data provenance

    • Test Set Sample Size: Not specified. The document refers to "in-vitro testing" and "biocompatibility testing" but does not give sample sizes for these tests.
    • Data Provenance: Not explicitly stated but implied to be laboratory testing ("tested in the lab") for physical/mechanical properties and in-vitro/in-vivo animal testing for biocompatibility. There is no information regarding country of origin for the data (beyond the applicant being in Illinois, USA) or if it's retrospective or prospective.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    • Not Applicable. This document describes the evaluation of a dental material, not an AI/ML device that would require expert-established ground truth from medical images or clinical data. The "ground truth" for this device comes from standardized chemical, physical, and biological tests.

    4. Adjudication method for the test set

    • Not Applicable. As above, no expert adjudication is mentioned or relevant for this type of device evaluation.

    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 document is for a dental material, not an AI-powered diagnostic or assistive device. Therefore, no MRMC study or assessment of human reader improvement with AI assistance was performed or reported.

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

    • No. This document is for a dental material. There is no algorithm discussed.

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

    • The "ground truth" for this device's performance is established through objective, standardized laboratory measurements of physical/mechanical properties (e.g., flexural strength, water sorption) and biocompatibility tests (e.g., cytotoxicity, sensitization, irritation) against established international standards (ISO). For the in-vitro testing, the ground truth would be the observed bacterial/fungal growth or inhibition under controlled lab conditions.

    8. The sample size for the training set

    • Not Applicable. This is not an AI/ML device, so there is no "training set."

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

    • Not Applicable. This is not an AI/ML device, so there is no "training set."

    All-Bond Universal SC adhesive is used for:

    • Direct Restorations (e.g. resin-based composite, resin-modified glass ionomer, core build-ups)
    • Indirect Restorations (e.g. metal, glass, ceramics, zirconia/alumina)
    • Bonding Resin or Primer for Substrates
    • Desensitization/Sealing of Tooth
    • Intraoral Repair (e.g. chipped porcelain, additions to direct restorations)
    Device Description

    All-Bond Universal SC is an auto-polymerizing adhesive with a light-curing alternative. It is designed for the dentist who prefers not to light cure the adhesive layer under indirect restorations. All-Bond Universal SC has a low film thickness (<5 µm). All-Bond Universal SC has a chemical formulation that allows the adhesive to be used in either self-etch or total-etch mode, based on the clinical situation and dentist preference. All-Bond Universal SC is compatible with light-cured, self-cured, dual-cured resin composite and cement base materials for direct and indirect procedures without any additional activators.

    AI/ML Overview

    The provided text is a 510(k) summary for a dental adhesive, "All-Bond Universal SC," indicating its substantial equivalence to a predicate device, "ACE Bond SE." The summary focuses on chemical composition, physical/mechanical properties, and biocompatibility rather than clinical performance based on a test set and ground truth in the way one might expect for an AI/CADe device. Therefore, many of the requested categories about acceptance criteria, study design for a test set, expert involvement, and ground truth are not applicable or cannot be extracted from this document, as it describes a traditional dental adhesive, not a diagnostic or AI-powered medical device.

    However, I can extract the information that is present and indicate where the requested information is not available in the provided text.

    BiocompatibilityISO 7405:2008 standards"Not toxic in this test" (Oral Toxicity Study)

    Study Proving Device Meets Acceptance Criteria:

    The study proving the device meets acceptance criteria is described as "R&D testing protocols" conducted in the lab. These protocols were used to determine shear bond strength, microleakage, and film thickness (using a modified technique from ISO 4049). An evaluation of biocompatibility was conducted using ISO 7405:2008 and an Oral Toxicity Study (10 rats, 14 days). The conclusion is based on "Side by side comparisons" demonstrating substantial equivalence to the predicate device.


    2. Sample size used for the test set and the data provenance:

    • Sample Size for Test Set:
      • For physical/mechanical properties (shear bond strength, microleakage, film thickness): Not explicitly stated. The document mentions "R&D testing protocols" but does not quantify the number of samples or tests.
      • For Biocompatibility: 10 rats were used for the Oral Toxicity Study.
    • Data Provenance: The studies were conducted in the lab by BISCO, Inc. (location: Schaumburg, IL, USA). The studies are retrospective regarding their submission date, as the tests were performed prior to filing the 510(k).

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • This information is not applicable to this type of device and study. The "ground truth" for a dental adhesive focuses on its physical, chemical, and biological properties, which are measured using established scientific/engineering methods and standards (e.g., ISO standards, R&D protocols), not typically through expert consensus readings of images or clinical cases.

    4. Adjudication method for the test set:

    • This information is not applicable to this type of device and study. Adjudication methods like 2+1 or 3+1 are used for human expert consensus in diagnostic studies, not for the analytical testing of material properties.

    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. This is not an AI/CADe device, and therefore, no MRMC study was performed as described.

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

    • This information is not applicable. This is not an AI/CADe device.

    7. The type of ground truth used:

    • The "ground truth" for the performance claims relies on:
      • Measurements against industry standards/protocols: For film thickness (modified ISO 4049) and biocompatibility (ISO 7405:2008).
      • Results from R&D testing protocols: For shear bond strength and microleakage.
      • Direct chemical and physical comparisons to a legally marketed predicate device.

    8. The sample size for the training set:

    • This information is not applicable. This is not an AI/CADe device, and therefore, there is no "training set" in the context of machine learning.

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

    • This information is not applicable. As there is no training set for an AI model, there is no ground truth established for such a purpose.
