    BruxZir™ TintEFX Coloring Liquid

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

    BruxZir™ TintEFX Coloring Liquid is used for coloring pre-sintered zirconia structures.

    Device Description

    BruxZirTM TintEFX Coloring Liquid comprises a set of solutions that enhance the esthetic properties of zirconia restorations. The solution is applied to the zirconia restorations before sintering, by dipping the framework into the liquid or by using a metal-free brush. Afterwards, the structure is dried and subsequently sintered at temperatures above 1400°C.

    BruxZir™ TintEFX Coloring Liquid is available in 14 different colors, Brown, Green, Blue, Pink, Orange, Purple, Grey, Yellow, G00, G0, G1, G3, G4, and G5. The devices can be used on the gingival part, body part, and/or incisal part of dental restoration to provide esthetic properties and mimic nature tooth color. The devices are intended to be used solely by dental technicians for fabrication of zirconia restorations for individual dental patients.

    AI/ML Overview

    This document describes the FDA's 510(k) clearance for BruxZir™ TintEFX Coloring Liquid, a dental product. It primarily focuses on demonstrating substantial equivalence to a predicate device, not on proving device performance against specific acceptance criteria for an AI/CADe medical device study. Therefore, most of the information requested in your prompt (e.g., sample size for test set, number of experts, MRMC studies, training set details) is not applicable to this type of submission.

    This document is for a "Porcelain Powder For Clinical Use" (though the device itself is a liquid for coloring zirconia) which falls under a general controls classification. The "performance data" presented are non-clinical tests to show the new device performs similarly to the predicate and meets general dental material standards.

    However, I can extract the information that is present and explain why other aspects are not applicable.

    Explanation of Non-Applicability:

    The requested information (e.g., sample sizes for test sets, data provenance, expert adjudication, MRMC studies, standalone algorithm performance, ground truth establishment for training) is highly relevant for the assessment of AI/CADe (Computer-Assisted Detection/Diagnosis) medical devices or other diagnostic/interpretive devices where the primary function is to analyze data (like medical images) and provide an output that impacts a clinical decision.

    This document describes a coloring liquid used in the fabrication of dental restorations. Its performance is evaluated based on material properties (flexural strength, chemical solubility, visual shade) and biocompatibility, not on its ability to "diagnose" or "detect" anything using an algorithm. Therefore, the concepts of "test set," "training set," "ground truth experts," or "AI assistance" do not apply.


    Here's the breakdown of the available information, addressing your points where applicable:

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

    The document doesn't explicitly state "acceptance criteria" in the format of a diagnostic performance study (e.g., sensitivity, specificity thresholds). Instead, it refers to industry standards and general material requirements. The "performance" is reported as meeting these standards.

    Shelf Life0.5 years (accelerated aging)ASTM F1980-21
    Packaging IntegritySuitable to withstand distribution environmentSimilar to reference device (K220960) packaging validation

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

    The document doesn't explicitly state the sample sizes for each specific test (e.g., number of restorations tested for flexural strength, number of specimens for chemical solubility). It also doesn't specify the country of origin for the data or whether the studies were retrospective or prospective.

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

    For the "Visual Shade Evaluation," the document states "qualified reviewers" performed the evaluation. However, it does not specify the number of reviewers, their professional qualifications (e.g., dental technicians with X years of experience, ceramists), or how "qualified" is defined.

    4. Adjudication Method for the Test Set:

    For the "Visual Shade Evaluation," it simply states the evaluation was done "against the reference shade guides." No specific adjudication method (e.g., 2+1, 3+1) is described for resolving discrepancies, implying a single reviewer's assessment or a consensus without a formal adjudication process. For other tests, the outcomes are quantitative measurements against established standards, so an adjudication method is not applicable.

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

    No, an MRMC comparative effectiveness study was not done. The submission is focused on demonstrating substantial equivalence to a predicate device through non-clinical performance testing.

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

    This device is not an AI/algorithm-based device, so the concept of "standalone performance" in that context is not applicable. The device is a coloring liquid used in the fabrication process of dental prosthetics.

    7. The Type of Ground Truth Used:

    • Mechanical Properties (Flexural Strength, Chemical Solubility): The ground truth is defined by established international standards (ISO 6872:2015/Amd 1:2018), which specify minimum acceptable performance values.
    • Biocompatibility: Ground truth is established by international standard (ISO 10993-1, ISO 10993-5:2009) requirements.
    • Visual Shade Evaluation: Ground truth is established by "reference shade guides" and evaluation by "qualified reviewers."
    • Shelf Life: Ground truth is based on the methodology outlined in ASTM F1980-21.
    • Packaging Validation: Ground truth is based on established testing protocols to ensure packaging integrity.

    8. The Sample Size for the Training Set:

    This device is not an AI/machine learning device, so there is no concept of a "training set" in the traditional sense.

    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 documentation is a 510(k) summary for a medical device called "Coloring Liquid." It focuses on demonstrating substantial equivalence to a predicate device, rather than proving the device meets specific performance acceptance criteria through a clinical study involving human subjects or complex algorithms.

    Therefore, many of the requested sections (2, 3, 4, 5, 6, 7, 8, 9) regarding sample sizes, expert ground truth, adjudication methods, multi-reader studies, and training sets are not applicable to this type of submission. This document describes a chemical product used in dentistry, not an AI/ML-driven diagnostic or prognostic device.

    Here's an analysis based on the information available:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document reports and compares safety testing results, which can be interpreted as demonstrating that the device meets acceptance criteria for biocompatibility.

    Test DescriptionAcceptance Criteria (Implied)Reported Device Performance (Subject Device)Reported Device Performance (Predicate Device K141723)
    Cytotoxicity (ISO 10993-5:2009)No cytotoxicity effectNo cytotoxicity effectNo cytotoxicity effect

    Genotoxicity (ISO 10993-3:2003)No genotoxic effects observedNo genotoxic effects observedNo genotoxic effects observed

    Study Proving Device Meets Acceptance Criteria:

    The document states: "Bench testing was performed to ensure that the Coloring Liquid met its specifications. All tests were verified to meet acceptance criteria. Biocompatibility testing was performed to verify the equivalent safety of the materials that are used."

    This indicates that internal bench tests and specific biocompatibility tests, following ISO 10993 standards, were conducted to demonstrate the safety of the device. The results of these biocompatibility tests are summarized in Table 5.2. The conclusion drawn is that the subject device's performance in these safety tests is comparable to the predicate device, thus meeting the implied safety acceptance criteria for this type of product.

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

    • Not Applicable. This submission is for a material (coloring liquid) and focuses on biocompatibility and physicochemical properties, not a diagnostic or AI-powered imaging device that would require a "test set" of patient data in the typical sense. Biocompatibility tests are usually conducted on material samples in controlled laboratory settings (e.g., cell cultures, animal models as per ISO standards). The document does not specify the number of samples or specific animal models used, but refers to ISO standards.

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

    • Not Applicable. Ground truth, in the context of device performance, typically refers to a definitive diagnosis or outcome for diagnostic/prognostic devices. For a coloring liquid, "ground truth" would relate to the chemical composition, color properties, and biocompatibility, which are verified through objective scientific methods and established ISO standards, not expert consensus in a clinical reading scenario.

    4. Adjudication Method for the Test Set:

    • Not Applicable. As there is no "test set" in the context of clinical interpretation, no adjudication method is relevant. Biocompatibility test results are typically interpreted by qualified laboratory personnel following established protocols.

    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. The device is a "Coloring Liquid" for dental zirconia, not an AI-assisted diagnostic tool.

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

    • Not Applicable. The device is a chemical product, not an algorithm.

    7. The Type of Ground Truth Used:

    • Objective Test Results / Standardized Biocompatibility Assays. For this device, the "ground truth" for proving safety and effectiveness (as understood in this context) comes from the results of standardized laboratory tests (e.g., cytotoxicity assays, irritation tests, sensitization tests, systemic toxicity tests, genotoxicity assays) conducted according to recognized international standards (ISO 10993 series). These tests provide objective data on the biological responses to the material.

    8. The Sample Size for the Training Set:

    • Not Applicable. This is not an AI/ML device that requires a training set.

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

    • Not Applicable. This is not an AI/ML device that requires a training set.

    The subject device is water-based solution. It is used for the individual staining of dental zirconia frameworks and restorations prior to the final sintering. It enables trained dental technicians to adjust the restoration to match the natural color of the patient's teeth. The liquid has 45 shades are available in 15ml, 20ml, 30ml, 40ml and 100ml volumes. We offer the product in four different names: DMAX Coloring Liquid, Chang's Liquid, Confident Coloring Liquid, CAMeleon Coloring Liquid. They are just different names for the same products.

    AI/ML Overview

    This document describes the premarket notification for DMAX Coloring Liquid and related products. It is not an AI/ML medical device, but rather a dental accessory used for shading zirconia dental restorations. Therefore, the information requested about acceptance criteria and study design from an AI/ML perspective is not applicable here.

    However, I can provide the available information regarding the device's performance testing and comparison to a predicate device.

    Performance Data (Non-Clinical) - Not AI/ML Specific

    The performance data provided is for a dental coloring liquid, not an AI/ML device. The "acceptance criteria" in this context are implicitly met if the test results support substantial equivalence to the predicate device and comply with relevant standards.

    1. Table of Acceptance Criteria and Reported Device Performance

    Since this is not an AI/ML device, there are no "acceptance criteria" in the typical sense of metrics like sensitivity, specificity, or AUC. Instead, the device's performance is demonstrated through non-clinical bench testing to ensure safety and functionality, and its substantial equivalence to a predicate device is established by comparing characteristics.

    Test CategoryAcceptance Criteria (Implicit: Supports Substantial Equivalence to Predicate, meets standards)Reported Device Performance
    Shelf LifePassed (implied)Test results support substantial equivalence to the predicate device.
    ISO 10993-5 CytotoxicityPassed (implied)Test results support substantial equivalence to the predicate device.

    2. Sample Size for Test Set and Data Provenance

    This information is not provided in the document. The tests performed are non-clinical bench tests (e.g., in vitro biocompatibility, chemical analysis), not tests involving patient data or clinical samples in the way an AI/ML device would be evaluated.

    3. Number of Experts and Qualifications for Ground Truth

    Not applicable. The "ground truth" here relates to the chemical and physical properties of the coloring liquid and its biocompatibility, which are determined by established scientific methods and laboratory testing, not by expert interpretation of images or patient data.

    4. Adjudication Method

    Not applicable. This is not a study involving human readers or interpretations needing adjudication.

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

    Not applicable. This is a non-AI/ML dental accessory.

    6. Standalone (Algorithm Only) Performance

    Not applicable. This is a non-AI/ML dental accessory.

    7. Type of Ground Truth Used

    The "ground truth" for this device's evaluation is derived from:

    • Bench Test Results: Objective measurements from laboratory tests for physicochemical properties (pH, boiling point, density, solubility) and biocompatibility (cytotoxicity, sensitization, irritation, oral mucosa irritation) according to referenced standards (e.g., ISO 10993).
    • Predicate Device Characteristics: Comparison to an already cleared device's known characteristics and performance to establish substantial equivalence.

    8. Sample Size for Training Set

    Not applicable. This device does not involve a training set as it is not an AI/ML algorithm.

    9. How Ground Truth for Training Set Was Established

    Not applicable. As there is no training set for an AI/ML algorithm, this question is not relevant.

    Summary of Device and Performance Evaluation:

    The DMAX Coloring Liquid family of products are water-based solutions with inorganic pigments used to shade zirconia dental restorations. Their premarket notification to the FDA focuses on demonstrating substantial equivalence to an existing predicate device (LUMINESSE® PRE-SINTERED ZIRCONIA COLORING LIQUID). This is achieved through:

    • Comparison of Device Characteristics: Showing similar indications for use, principle of operation, technology (water-based with inorganic pigments), prescription use, target population, general physical form, and sterility to the predicate.
    • Bench Testing: Non-clinical tests were conducted according to relevant standards (e.g., ISO 10993 for biocompatibility) for properties such as shelf life, cytotoxicity, sensitization, irritation, oral mucosa irritation, appearance, volume, packaging, uniformity, and chemical solubility. The document states that "All the test results support substantial equivalence to the predicate devices."
    • Physicochemical Property Comparison: Specific values for pH, boiling point, density, specific gravity, and water solubility were provided for both the subject device and the predicate device, indicating comparable profiles.

    The differences noted (packaging volume, number of shades, shelf life/storage conditions) were deemed not to raise new questions of safety or effectiveness, particularly because the shelf life test results supported equivalence despite different storage duration/conditions.

    LUMINESSE PRE-SINTERED ZIRCONIA COLORING LIQUID

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

    Luminesse Pre-Sintered Zirconia Coloring Liquid is a device that can be used as an accessory to zirconium dioxide dental restorative material such as Luminesse ZR blanks to provide individualized tooth (or teeth) shading. It is intended to be used solely by certified dental technicians for fabrication of all ceramic restorations for individual dental patients.

    Device Description

    Luminesse® Pre-sintered Zirconia Coloring Liquid is a device that can be used as an accessory to zirconium dioxide dental restorative material such as Luminesse® ZR blanks to provide individualized tooth (or teeth) shading. It is a liquid ceramic aid for complete or partial coloring of all zirconium oxide blanks. Dental restorations are designed and manufactured by a certified dental professional (Technician) using CAD/CAM technology.

    AI/ML Overview

    The provided document is a 510(k) Pre-Market Notification for a medical device called "Luminesse® Pre-Sintered Zirconia Coloring Liquid." This type of submission aims to demonstrate that a new device is substantially equivalent to a legally marketed predicate device, rather than proving its safety and effectiveness through clinical trials with specific acceptance criteria as you might see for a novel, high-risk device.

    Therefore, the document does not contain a study that proves the device meets specific acceptance criteria in the traditional sense of a clinical or performance study for an AI/software device. Instead, it demonstrates substantial equivalence based on a comparison of technological characteristics and performance data that the new device shares with a predicate device.

    Here's a breakdown of the requested information based on the provided document, highlighting where the information is not applicable due to the nature of a 510(k) substantial equivalence submission for this type of device:


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

    Since this is a 510(k) for a coloring liquid, the "acceptance criteria" are not framed as performance metrics for an AI or diagnostic device, but rather as characteristics of the material that show it is similar to the predicate. The performance data presented refers to standard physical and chemical properties.

    Conclusion from Document: The document concludes that "the differences…do not raise new questions of safety and effectiveness." The data supplied for both new and predicate device on physical and mechanical properties demonstrate similarity, "albeit unequal results," and are "within the expected specifications for zirconia dying liquid materials for dental application."


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

    • Not Applicable (N/A): This is a 510(k) submission for a coloring liquid, not a diagnostic or AI device that typically involves test sets of patient data. The "test set" here refers to the samples of the coloring liquid itself that were tested for physical and chemical properties. There is no mention of the specific number of liquid samples tested, nor is there information about data provenance in terms of country of origin or retrospective/prospective studies. The performance data is based on material property testing.

    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 (N/A): Ground truth established by experts is relevant for diagnostic or AI systems where human interpretation is the gold standard. For a coloring liquid, the "ground truth" is determined by objective physical and chemical measurements (e.g., pH, density, boiling point), which are standard laboratory procedures, not expert consensus on qualitative data.

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

    • Not Applicable (N/A): Adjudication methods like 2+1 or 3+1 are used to resolve discrepancies in expert interpretation, typically in studies involving human readers or AI. This is not relevant for the objective physical and chemical testing of a dental coloring liquid.

    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 (N/A): MRMC studies are used to evaluate the performance of diagnostic tools (often AI-assisted) by comparing multiple readers on multiple cases. This device is a coloring liquid, not a diagnostic or AI tool, so an MRMC study is not relevant.

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

    • Not Applicable (N/A): This concept applies to standalone AI algorithms. The Luminesse® Pre-Sintered Zirconia Coloring Liquid is a physical material, not an algorithm. Its performance is inherent to its physical and chemical properties.

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

    • Laboratory Measurements / Physical and Chemical Standards: The "ground truth" or reference for the device's characteristics are standardized measurements of physical properties (e.g., general physical form, specific physical form, odor, color, boiling point, density, specific gravity, solubility) and chemical properties (e.g., pH). These are determined in a laboratory setting using established analytical methods, not through expert consensus, pathology, or outcomes data in the clinical sense.

    8. The sample size for the training set

    • Not Applicable (N/A): This device is a material, not a machine learning model. Therefore, there is no "training set" in the context of AI or data-driven model development.

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

    • Not Applicable (N/A): Since there is no training set as described above, this question is not applicable.

    AI/ML Overview

    The provided documentation (K140491) does not describe an AI medical device or a study proving its performance against acceptance criteria in the context of AI. Instead, it is a 510(k) premarket notification for dental products: "Tanaka ZirColor™ Coloring Liquid, Tanaka ZirColor™ Dipping Liquid and Tanaka Enamel ZR™ Blocks."

    This document focuses on establishing substantial equivalence to previously cleared predicate devices (ZENO Zr Disc, Zenotec Color Zr, Zenostar Color Zr, Zenotec Zr Bridge, and Zenostar Zr Translucent cleared under K112710) based on intended use, technology, and performance, primarily through material composition and physicochemical testing, not AI performance metrics.

    Therefore, I cannot provide the requested information about acceptance criteria, device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment for an AI device. The document simply does not contain this type of information.

    UPCERA COLORING LIQUID (I AND II )

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

    Upcera Coloring Liquid (I and II) is a liquid used for the complete or partial coloration of milled Upcera zirconia substructure and anatomy before sintering.

    Device Description

    Upcera Coloring Liquid (I and II) are water based coloring liquids, which consist of watery, acidic metal salt solutions. They are used for the individual staining of dental zirconia frameworks and restorations prior to the final sintering of the restoration, enabling the user to adjust the restoration to match the natural color of the patient's teeth. Upcera Coloring Liquid I is provided in 21 different shades, and Upcera Coloring Liquid II is provided in 16 different shades, which are corresponding to patient's closest tooth color. For staining, the zirconia materials have to be immerged into the liquids or to be brushed with the liquids, prior to sintering at high temperatures.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for a medical device called "Upcera Coloring Liquid (I and II)". It does not contain information about acceptance criteria and a study proving the device meets those criteria in the context of an AI/ML powered medical device.

    The document is a submission to the FDA for a coloring liquid for dental zirconia, which is a material used in dental restorations. The "performance testing" described in Section 5.9 and Table 5.2 refers to biocompatibility testing of the coloring liquid itself, which is a standard requirement for materials that will be in contact with the human body, not a performance study of an AI device.

    Therefore, I cannot provide the requested information about acceptance criteria and a study as the device described is not an AI/ML powered medical device.
