    Intended Use

    The TOKUYAMA UNIVERSAL BOND II is indicated for:

    • Direct anterior and posterior restorations with light-curing, dual-curing, and self-curing composite materials
    • Intraoral repair of composite restorations, porcelain fused to metal, metal, and all-ceramic restorations without an additional primer
    • Cementation of indirect restorations and veneers when combined with light-cure, dual-cure, and self-curing resin cements
    • Bonding of core build-ups made of core build-up materials
    • Bonding of denture resin to metal base, clasp or attachment
    • Repair of denture with metal base, clasp or attachment
    • Bonding of opaque resin to a metal base in the fabrication of resin-faced crowns
    Device Description

    The TOKUYAMA UNIVERSAL BOND II device is a two-component self-cured dental adhesive system for both direct and indirect restorations that can be used with self-etch, selective-enamel-etch and total-etch techniques. As a universal adhesive, TOKUYAMA UNIVERSAL BOND II has been designed to be fully compatible with light-cured, self-cured and dual-cured composite materials.
    TOKUYAMA UNIVERSAL BOND II contains phosphoric acid monomer, bisphenol A di(2-hydroxy propoxy) dimethacrylate (Bis-GMA), triethylene glycol dimethacrylate (TEGDMA), 2-Hydroxyethyl methacrylate (HEMA), MTU-6 (thiouracil monomer), silane coupling agent, peroxide, borate catalyst, acetone, ethanol and purified water.
    Bond A and Bond B are packaged in separate plastic bottles. A group of polymerization agents is contained in the Bond A and Bond B to avoid reaction during storage, and the polymerization reaction begins upon mixing. When the mixture is applied thinly to adherends and concentrated by air-drying, a cured layer is formed by polymerization of methacrylic monomers. The cured layer functions as an adhesive layer for enhancing adhesiveness of polymerization resin to the adherends.
    The device improves the bond strength of polymerizable resin material (adhesive resin cement, acrylic resin, and composite resin) to indirect restorative materials such as glass-ceramics (porcelain), oxide-ceramics (zirconia and alumina), metals (precious and non-precious), and resin materials including inorganic filler.
    The TOKUYAMA UNIVERSAL BOND device does not come sterilized and is not intended to be sterilized prior to use.

    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 does not explicitly state the specific sample sizes for each physical property test. It mentions that "Non-clinical testing of the physical properties of the OMNICHROMA FLOW device was conducted in accordance with ISO 4049:2009, 'Dentistry -- Polymer-based Restorative Materials.'" The ISO standard would define the required sample sizes for each test.

    The data provenance is not specified regarding country of origin or whether it was retrospective or prospective. It is implied that the testing was conducted by or for Tokuyama Dental Corporation, a Japanese company.

    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)

    This information is not applicable. The device is a "tooth shade resin material," and its performance is evaluated against engineering standards (ISO 4049) and biocompatibility, not by expert interpretation of images or clinical outcomes that would require ground truth established by medical experts like radiologists.

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

    This information is not applicable as the study involves physical property testing against an engineering standard, not clinical adjudication of diagnoses or interpretations.

    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, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The device is a dental restorative material, not an AI-assisted diagnostic tool.

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

    This question is not applicable. The device is a physical material, not an algorithm. The performance testing was of the material itself.

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

    The ground truth for the physical property testing is based on the requirements and methodologies outlined in ISO 4049:2009, "Dentistry -- Polymer-based Restorative Materials," which are standardized engineering and material science criteria. For biocompatibility, the ground truth is established by standard biological evaluation methods (cytotoxicity, sensitization, oral mucosa irritation, subacute systemic toxicity, acute systemic toxicity, and genotoxicity testing).

    8. The sample size for the training set

    This information is not applicable. The device is a physical material, not an AI model, and therefore does not have a "training set" in the context of machine learning.

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

    This information is not applicable for the reason stated in point 8.

    Not applicable. This is a material, not an algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for the performance claims is the requirements specified in ISO 4049:2009, "Dentistry -- Polymer-based Restorative Materials." The device's physical and chemical properties were measured and compared against these established international standards.

    For biocompatibility, the ground truth relies on the established safety record of identical ingredients used in previously authorized devices (ESTELITE BULK FILL Flow, ESTELITE SIGMA QUICK, and ESTELITE FLOW QUICK) over many years without reportable adverse incidents. This is justification for not requiring further biocompatibility testing under Section 6 of ISO 10993-1.

    8. The Sample Size for the Training Set

    Not applicable. This is not a machine learning or AI device that requires a training set.

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

    Not applicable, as no training set was used.

    Intended Use

    The TOKUYAMA UNIVERSAL BOND is indicated for:

    • Direct anterior and posterior restorations with light-curing, and self-curing composite materials

    • Intraoral repair of composite restorations, porcelain fused to metal, and all-ceramic restorations without an additional primer

    • Cementation of indirect restorations and veners when combined with light-cure, and self-curing resin cements

    • Bonding of core build-ups made of core build-up materials

    • Bonding of denture resin to metal base, clasp or attachment

    • Repair of denture with metal base, clasp or attachment

    • Bonding of opaque resin to a metal base in the fabrication of resin-faced crowns

    Device Description

    The TOKUYAMA UNIVERSAL BOND device is a two-component self-cured dental adhesive system for both direct and indirect restorations that can be used with self-etch, selective-enamel-etch, and total-etch techniques. The TOKUYAMA UNIVERSAL BOND device is fully compatible with light-cured. self-cured, and dual-cured composite materials.

    Bond A and Bond B are packaged in separate plastic bottles. A group of polymerization agents is contained in the Bond A and Bond B to avoid reaction during storage, and the polymerization reaction begins upon mixing. When the mixture is applied thinly to adherends and concentrate by air-drying, a cured layer is formed by polymerization of methacrylic monomers. The cured layer functions as an adhesive layer for enhancing adhesiveness of polymerization resin to the adherends.

    The device improves the bond strength of polymerizable resin material (adhesive resin cement, acrylic resin, and composite resin) to indirect restorative materials such as glass-ceramics (porcelain), oxide-ceramics (zirconia and alumina), metals (precious and non-precious), and resin materials including inorganic filler.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for a dental adhesive device, the TOKUYAMA UNIVERSAL BOND. It describes the device, its intended use, technological characteristics, and non-clinical testing performed to demonstrate substantial equivalence to predicate devices.

    However, the document does NOT describe an AI/ML-based medical device. Therefore, it does not contain the information required to answer the questions about acceptance criteria, study design for AI models (sample size, data provenance, ground truth, expert adjudication, MRMC studies, standalone performance, training set details).

    The Acceptance Criteria and Study Proof for the TOKUYAMA UNIVERSAL BOND device are entirely based on physical property testing as it is a material-based dental product, not an AI diagnostic or assistance tool.

    Here's a summary of the acceptance criteria and proof as presented for this specific dental device:

    Acceptance Criteria and Reported Device Performance

    The acceptance criteria for the TOKUYAMA UNIVERSAL BOND device are based on achieving certain tensile bond strengths to various dental materials, as well as satisfactory working time, paintability, and appearance.

    Acceptance Criteria ItemAcceptance Criteria (In-house Specification)Reported Device Performance (TOKUYAMA UNIVERSAL BOND)
    Tensile bond strength to enamel> 12 MPa> 12 MPa
    Tensile bond strength to dentin> 10 MPa> 10 MPa
    Tensile bond strength to metal> 12 MPa> 12 MPa
    Tensile bond strength to porcelain≥ 10 MPa≥ 10 MPa
    Tensile bond strength to zirconia≥ 10 MPa≥ 10 MPa
    Tensile bond strength to resin material including inorganic filler≥ 10 MPa≥ 10 MPa
    Working timeCured after 90 seconds (Confirmation)Confirmed to be cured after 90 seconds
    PaintabilityEven film formed (Evaluation)Even film formed
    AppearanceVisual inspection (Normal)Normal

    (Note: The tables in the original document present the performance of the predicate and reference devices against the same specifications, with all devices meeting these criteria.)

    Study that Proves the Device Meets the Acceptance Criteria:

    The study conducted is a series of non-clinical, benchtop physical property tests.

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

      • The document does not explicitly state the sample size (number of individual samples or replicates tested) for each physical property. It only states that "Non-clinical testing of the following physical properties was conducted."
      • Data Provenance: The tests were conducted by Tokuyama Dental Corporation, based in Japan. This implies the data originates from their internal laboratory testing. The data is retrospective in the sense that it was generated prior to the 510(k) submission.
    2. Number of experts used to establish the ground truth for the test set and qualifications of those experts:

      • Not applicable. For physical property testing of a dental material, "ground truth" is established by the direct measurement of physical properties (e.g., bond strength in MPa) using established testing standards (ISO/TS 11405:2015). This does not involve human expert adjudication or consensus in the way an AI diagnostic would require for image interpretation.
    3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

      • Not applicable. As this is a physical property test, not an interpretive one, there is no adjudication process involving multiple human readers. The measurement results are directly compared against the pre-defined in-house specifications.
    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 device is a material, not an AI or a system that assists human readers. Therefore, an MRMC study is irrelevant.
    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Not applicable. This device has no algorithm and does not perform any diagnostic or interpretive function. Its performance is intrinsic to its physical and chemical properties.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

      • The "ground truth" for this device's performance is the direct, quantitative measurement of physical properties (tensile bond strength) and qualitative assessments (working time, paintability, appearance) against pre-defined, standardized specifications. The testing was conducted pursuant to Section 5.1 of ISO/TS 11405:2015 for tensile bond strength tests.
    7. The sample size for the training set:

      • Not applicable. This is not an AI/ML device, so there is no "training set."
    8. How the ground truth for the training set was established:

      • Not applicable. There is no training set for this type of device.

    In summary, the provided document pertains to a dental bonding agent, and therefore the "acceptance criteria" and "proof" relate to its physical and chemical characteristics and performance as a material, rather than the statistical or clinical performance metrics associated with AI/ML medical devices.

    AI/ML Overview

    I am sorry, but the provided text does not contain the information needed to answer your request. The document is an FDA 510(k) clearance letter and summary for a dental resin, focusing on its substantial equivalence to predicate devices and non-clinical testing.

The device comes in five shades, namely U (Universal), A1, A2, A3, and B1.

    AI/ML Overview

    This document describes the premarket notification (510(k)) for the Tokuyama Dental Corporation's "ESTELITE BULK FILL Flow tooth shade resin material." The FDA determined the device is substantially equivalent to legally marketed predicate devices.

    Here's the breakdown of the acceptance criteria and the study that proves the device meets them, based on the provided text:

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

    The document provides a table comparing the new device (ESTELITE BULK FILL Flow) to its primary predicate (ESTELITE FLOW QUICK) and references ISO 4049:2009 for many properties.

    CharacteristicAcceptance Criteria (Predicate/ISO 4049)Reported Device Performance (ESTELITE BULK FILL Flow)

    Diametral Tensile StrengthConformed to ISO 4049 requirementConformed to ISO 4049 requirement
    BiocompatibilityAll ingredients authorized by FDA for similar devicesAll ingredients authorized by FDA for similar devices

    Note: The document explicitly states "Conformed to the requirement of ISO 4049" for several physical properties, implying these are the acceptance criteria and the device met them. For other properties, the predicate's performance serves as the benchmark for substantial equivalence.

    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 does not explicitly state the sample sizes used for the non-clinical physical property tests. It only states that the testing was "conducted in accordance with ISO 4049:2009," which would imply adherence to its specified sample sizes if applicable.

    The provenance of the data is implied to be from Tokuyama Dental Corporation, which is based in Japan, as per the submitter information. The testing is non-clinical, so the retrospective/prospective distinction for human data is not applicable.

    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)

    This information is not applicable as the studies conducted were non-clinical, measuring physical properties of the material in a laboratory setting, not evaluating diagnostic performance with human judgment.

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

    This information is not applicable as there were no human expert judgments or adjudications involved in establishing the ground truth for the physical property tests.

    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. The device is a dental material, not an AI-assisted diagnostic tool. The document states: "There were no clinical tests performed for the ESTELITE BULK FILL Flow device."

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

    Yes, in a sense, a standalone assessment of the material's properties was performed by conducting non-clinical physical property tests. However, this is not a "standalone algorithm" in the context of AI. It refers to the intrinsic performance of the material itself.

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

    The ground truth for the performance data of the device was established through laboratory measurements of physical properties according to published standards (ISO 4049:2009). For biocompatibility, the ground truth was based on prior FDA authorization of the device's ingredients in other similar devices and the historical absence of adverse events.

    8. The sample size for the training set

    This information is not applicable. The device is a dental material, not an AI/ML algorithm that requires a training set. The performance data presented are from testing the physical properties of the final product.

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

    This information is not applicable as there was no training set for an AI/ML algorithm.

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The ESTECEM device is an adhesive resin cementation of crowns, bridges, inlays, and onlays made of glass/oxide ceramics (porcelain, zirconia and alumina), metals/alloys (precious) and resin materials including inorganic filler (composite materials). The ESTECEM device is indicated for:

    • Repair of fractured porcelain fused to metal crowns and all ceramic restorations

    • Cementation of veneers

    • Cementation of adhesion bridges

    • Cementation of metal or resin cores, metal or glass-fiber posts

    Device Description

    The ESTECEM device is a dual-cure (light and/or self-cure), radiopaque, adhesive resin cement system with excellent handling, esthetic and adhesive properties to teeth and all prosthetic materials. The main components of the ESTECEM device are (1) the paste (A/B) and (2) primer kit. The paste and primer are packaged in plastic syringes and plastic bottles, respectively. The device also comes with a mixing dish (dispensing well), disposable applicator, and cement mixing tip.

    The paste is dispensed in an automix syringe and is available in various shades (universal, clear, brown and white-opaque). The primer kit components consist of ESTELINK (bond A/bond B) and Tokuyama Universal Primer (A/B). The ESTELINK bond promotes the adhesion of the paste to the tooth structure. The Tokuyama Universal Primer enhances the adhesion of the paste to prosthetic materials.

    The ESTECEM device does not come sterilized and is not intended to be sterilized prior to use.

    AI/ML Overview

    This document describes the premarket notification for the ESTECEM dental adhesive resin cement system. The acceptance criteria and the study proving the device meets these criteria are detailed in section "807.92(b)(1): Non-clinical Testing" and the "Predicate devices" table, primarily through non-clinical bench testing and comparison to predicate devices.

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria for ESTECEM are primarily demonstrated through non-clinical testing, comparing its performance to established standards (ISO 4049:2009, ISO 7405:2008) and the technological characteristics of predicate devices. The document does not provide a direct table of set acceptance values versus measured values for each criterion. Instead, it states that the ESTECEM device's material properties, principles of operation, and performance characteristics are comparable to the selected predicates and that it is as safe, as effective, and performs as well as or better than the predicate devices.

    However, based on the non-clinical testing performed, we can infer the tested parameters as the acceptance criteria domains:

    Acceptance Criterion (Inferred from testing)Reported Device Performance (Summary)
    Film thickness"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    Working time"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    Setting time"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    Flexural strength"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    Water sorption"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    Color stability"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    Radio-opacity"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    Tensile strength"comparable to the selected predicates" (implied to meet relevant ISO standards for dental cements)
    BiocompatibilityDeemed acceptable based on testing in accordance with ISO 7405:2008, ISO 10993-1:2009, ISO 10993-3 (genotoxicity), ISO 10993-5 (cytotoxicity), ISO 10993-10 (sensitization and irritation), and ISO 10993-11 (systemic toxicity). Concluded to be "as safe" as predicate devices.

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

    The document does not specify a distinct "test set" in the context of an AI/ML device. Instead, the performance was evaluated through non-clinical bench testing of the ESTECEM dental adhesive resin cement. The specific sample sizes for each physical property and biocompatibility test are not provided in this summary.

    The data provenance is retrospective, as it involves laboratory testing of the manufactured device. The country of origin for the testing data is not explicitly stated, but the manufacturer, Tokuyama Dental Corporation, is based in Japan.

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

    Not applicable. This is a medical device approval that relies on physical and chemical bench testing and biocompatibility assessments, not on expert adjudication of diagnostic outputs.

    4. Adjudication Method for the Test Set

    Not applicable. See point 3.

    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 a dental material device, not an AI/ML diagnostic or assistive device.

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

    Not applicable. This is a dental material device, not an AI/ML algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for the non-clinical testing was defined by established International Organization for Standardization (ISO) standards for dental materials. Specifically:

    • Physical Properties: ISO 4049:2009
    • Biocompatibility: ISO 7405:2008, ISO 10993-1:2009, ISO 10993-3 (genotoxicity), ISO 10993-5 (cytotoxicity), ISO 10993-10 (sensitization and irritation), and ISO 10993-11 (systemic toxicity).

    The performance of the ESTECEM device was compared against the requirements and typical performance characteristics of legally marketed predicate devices, implying that the established performance of these predicates served as a benchmark for substantial equivalence.

    8. The Sample Size for the Training Set

    Not applicable. This is a dental material device and does not involve AI/ML models that require a training set.

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

    Not applicable. See point 8.
