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.
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 Characteristic | Acceptance Criteria (EN ISO 17730:2020) | Reported Device Performance (Profisil® Fluoride Varnish) | Conclusion |

Dynamic viscosity | Not explicitly stated, but within standard requirements | Assessed and verified against EN ISO 17730:2020 | Fulfilled |
Fluoride release | Not explicitly stated, but within standard requirements | Assessed and verified against EN ISO 17730:2020 | Fulfilled; equivalent rate to predicate |
Electron microscopy (SEM) study | Not explicitly stated, but within standard requirements | Assessed and verified against EN ISO 17730:2020 | Fulfilled |
Total Fluoride | Relevant for functioning as intended (EN ISO 17730:2020) | Contains 5% sodium fluoride (identical to predicate) | Equivalent |
Biocompatibility Acceptance Criteria:
Test | Standard | Acceptance Criteria | Reported Device Performance (Profisil® Fluoride Varnish) |
---|---|---|---|
Cytotoxicity | ISO 10993-5 | Meets ISO 10993-5 requirements | Met requirements |
Sensitization | ISO 10993-10 | Meets ISO 10993-10 requirements | Met requirements |
Irritation | ISO 10993-23 | Meets ISO 10993-23 requirements | Met requirements |
Pyrogenicity | ISO 10993-11 | Meets ISO 10993-11 requirements | Met requirements |
Systemic toxicity | ISO 10993-11 | Meets ISO 10993-11 requirements | Met 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.

Here's an analysis of the provided text regarding the acceptance criteria and study for the Visalys® Restorative Primer device.
It's important to note that this document is a 510(k) summary for a Class II medical device (Resin Tooth Bonding Agent). For such devices, the FDA often relies on substantial equivalence to a predicate device, which means direct comparative effectiveness studies with human subjects against the predicate might not always be required in the same way as for novel high-risk devices. The information provided is primarily focused on demonstrating this substantial equivalence through bench testing.
1. A table of acceptance criteria and the reported device performance
The acceptance criteria are implicitly derived from the bond strength values of the predicate device, CLEARFIL™ CERAMIC PRIMER PLUS (K150703). The study aims to show that Visalys® Restorative Primer performs similarly. No explicit "acceptance criteria" are stated as numerical thresholds; rather, the "Similar" conclusion in the table below serves as the acceptance.
Test Parameter / Material | Predicate Device Performance (CLEARFIL™ CERAMIC PRIMER PLUS) | Visalys® Restorative Primer Performance | Acceptance Criteria (Implicit) | Conclusion |
---|---|---|---|---|
Shear Bond Strength (MPa) | Similar performance to predicate | |||
Lithium disilicate | (8.9 MPa) | (10.2 MPa) | Achieving comparable shear bond strength | Similar |
Zirconium oxide | (8.4 MPa) | (7.5 MPa) | Achieving comparable shear bond strength | Similar |
Non-precious metal | (8.3 MPa) | (12.5 MPa) | Achieving comparable shear bond strength | Similar |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: The document does not explicitly state the number of samples or specimens used for the shear bond strength tests. It only lists the resulting bond strength values.
- Data Provenance: The study was conducted by Kettenbach GmbH & Co. KG (located in Eschenburg, Germany). The data is prospective as it involves new bench testing to support the 510(k) submission.

Not applicable. This device is a dental primer, and the ground truth for its performance (shear bond strength) is established through in vitro bench testing according to a recognized standard (ISO 16506). This does not involve human expert adjudication of images or clinical outcomes.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, as the evaluation is based on objective physical measurements (shear bond strength) from bench tests, not on subjective expert consensus or 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 primer, not an AI-based diagnostic tool. No MRMC study was conducted.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a dental primer, not an algorithm. The performance evaluation presented is strictly standalone in vitro bench testing of the product's physical properties.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The ground truth for the device's performance is established by objective physical measurements (shear bond strength) obtained through standardized in vitro bench testing adhering to relevant ISO standards (specifically, ISO 16506 Chapter A 2.2.5).
8. The sample size for the training set

Kingscross temporary crown and bridge material is intended to be used for fabrication of temporary prostheses, such as crowns, partial crowns, bridges, inlays, onlays and veneers, and for customization of prefabricated acrylic and metal crowns and for fabrication of long-term temporary restorations until a permanent restoration is fabricated.
Kingscross, which was developed by Kettenbach, is a highly esthetic composite of fabricating temporary restorations. The two-component system based on a multifunctional acryl composite is produced using no Bisphenol-A or Bisphenol-A precursors in the manufacturing process It has similar properties to a filling material and is available in the following shades: A1. A2, A3, A3.5, B1, B3, Bleach white. Kingscross temporary restorations can also be adjusted and customized using lightcuring composites. The two components (base and catalyst paste) are mixed by using a 50 ml cartridge at the ratio of 10:1 with a dispensing gun. By varying the percentages of two chemical components in the base paste with different percentages of organic peroxide in the catalyst paste four different product variations with different mechanical properties are realized.
The provided 510(k) summary for K122039, Kingscross Temporary Crown and Bridge Material, does not contain a study that proves the device meets specific acceptance criteria in the way typically expected for an AI/ML or diagnostic device.
Instead, this submission focuses on demonstrating substantial equivalence to predicate devices through a comparison of material properties and intended use. The "acceptance criteria" here are implied by the performance of the predicate devices and the relevant industry standards for dental materials.
Here's an analysis based on the provided text, addressing the requested information to the best of its ability given the type of device and submission:
1. Table of Acceptance Criteria and Reported Device Performance
Since this is a dental material, the "acceptance criteria" are not quantitative thresholds set for a specific study, but rather that the material's properties are comparable to established predicate devices and meet relevant industry standards.
Acceptance Criteria (Implied by Predicate Devices & Standards) | Reported Device Performance (Kingscross) |
---|---|
Biocompatibility: | "Kingscross materials' biocompatibility data is comparable to other materials on the market." (ISO 10993 family tests: cytotoxicity, mutagenicity, sensitization, mucosa irritation, chemical analysis) |
Mechanical Properties (Comparable to Predicate Devices & Industry Standards): | "The results indicate adequate strength results compared to leading temporary crown and bridge materials." "A comparison of the mechanical properties has also been performed in respect to the parameters and standards referenced under 'Summary of Non-Clinical Performance Testing'. The results also demonstrate substantial equivalence to the predicate devices." (Specific tests include: E-Modulus, Flexible strength, Impact strength, Compressive strength, Diametral tensile strength, Volume shrinkage, Max. temperature on cure, Inhibition layer, Extrusion force, as measured by ADA/ANSI and ISO standards). |
Intended Use: For fabrication of temporary prostheses (crowns, bridges, inlays, onlays, etc.). | "Kingscross temporary crown and bridge material is intended to be used for fabrication of temporary prostheses, such as crowns, partial crowns, bridges, inlays, onlays and veneers, and for customization of prefabricated acrylic and metal crowns and for fabrication of long-term temporary restorations until a permanent restoration is fabricated." (This matches the intended use of predicate devices, with some slight expansion for "customization" and "long-term temporary restorations" but argued as "no significant difference in intended use or technology"). |
Technology/Application: 2-paste system, dispensing gun, cartridge, mixing tip. | Matches predicate devices. |
Regarding the other requested information:
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 bench testing of material properties (E-Modulus, flexible strength, etc.) and biocompatibility tests.
- Sample sizes for these material tests are not specified. For example, it doesn't state how many samples were tested for compressive strength or E-Modulus for Kingscross or the predicate devices.
- Data provenance is not explicitly stated, but given the manufacturer is Kettenbach GmbH & Co KG in Germany, it's highly likely these tests were performed in Germany or by contract labs following international standards. These would be prospective tests performed specifically for this submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not applicable in the traditional sense for this device. This is a material claim, not a diagnostic or AI device that requires expert ground truth labeling of images or clinical cases. The "ground truth" here is adherence to established material testing standards (e.g., ADA/ANSI Specification No. 53, ISO 9917-1, OECD 487 for biocompatibility). The experts would be the chemists and material scientists performing and interpreting these standardized tests, but their number and specific qualifications are not detailed.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable. There is no expert adjudication process described for the quantitative material property tests. The results are objective measurements from standardized 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. This is not an AI/ML device or a diagnostic device involving human readers. Therefore, an MRMC study is not relevant and was not performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This is a dental material, not an algorithm or AI system.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The "ground truth" for this device's performance is established industry standards and the measured physical and chemical properties of the material itself, as well as the performance characteristics of the legally marketed predicate devices. No pathology, outcomes data, or expert consensus (in the clinical diagnosis sense) was used to establish ground truth for this type of submission.
8. The sample size for the training set
- Not applicable. This device is a material, not an AI/ML model that requires a training set.
9. How the ground truth for the training set was established
- Not applicable. As there is no training set for an AI/ML model, there is no ground truth established for one.

Identium® Impression Materials are addition-curing, elastomeric materials. Identium® Impression Materials have excellent flow and hydrophilic properties, high shear strength, dimensional accuracy and resistance to permanent deformation. The Identium® Impression Materials include three different viscosities (heavy-bodied, medium-bodied, light-bodied), available in an assortment of delivery systems: Traditional 1:1 50 ml automix cartridge version and 5:1 362 ml foil bags for use in most automatic dispensing and mixing systems (heavy-bodied and medium-bodied versions only). Most of the Identium® Impression Materials are available in a regular-set and a fast-set version.
This looks like a 510(k) premarket notification for dental impression materials, not an AI/ML device. Therefore, the typical "acceptance criteria and study that proves the device meets the acceptance criteria" structure, especially concerning AI/ML performance metrics, ground truth, expert adjudication, MRMC studies, and training sets, does not apply here.
Instead, this document describes a traditional medical device submission where substantial equivalence is demonstrated through:
- Comparison to predicate devices: Showing the new device has similar intended use and technological characteristics to legally marketed devices.
- Performance testing to established standards: Demonstrating compliance with relevant industry and regulatory standards for non-AI devices.
Here's how I can address the request based on the provided document, adapting the categories where necessary:
1. Table of Acceptance Criteria and Reported Device Performance
Criterion/Standard | Description | Reported Device Performance |
---|---|---|
Premarket Notification Guidance | "Guidance for Industry and FDA Staff: Dental Impression Materials - Premarket Notification (FOD#2203, 8/17/1998)" | "The results of performance testing demonstrated that Identium® Impression Material subject devices... are suitable for use as dental impression materials." |
ISO 4823:2000/Cor 1:2004/Amd 1:2007 | "Dentistry - Elastomeric impression materials." This standard specifies requirements and test methods for elastomeric impression materials for dental purposes. | "Identium® Impression Material subject devices... evaluated in accordance with the applicable criteria established in... ISO 4823... The results of performance testing demonstrated that Identium® Impression Material subject devices... are suitable for use as dental impression materials." |
Substantial Equivalence | The device should be as safe, as effective, and perform as well as or better than predicate devices. | "Identium® Impression Material subject devices... have been designed and manufactured to perform in a manner substantially equivalent to that of the predicate devices." "Based upon the similar intended use, the performance data according to ISO 4823, the evaluation/justification of the biocompatibility and the risk analysis acc. ISO 14971 the subject devices... are substantially equivalent to the predicate devices and can be considered to be as safe, as effective and performs as well as or better than the predicate devices." |
2. Sample Size Used for the Test Set and Data Provenance
This information is typically not included in a 510(k) summary for material performance testing. Standard ISO tests for dental materials use specific sample numbers as defined within the standard itself (e.g., a certain number of specimens for tensile strength, dimensional accuracy, etc.), but these details are not provided in this high-level summary. The data provenance would be laboratory testing conducted by or for the manufacturer (Kettenbach GmbH & Co. KG, Germany).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable for this type of device. "Ground truth" in the context of AI/ML refers to verified labels for image data, clinical diagnoses, etc. For material performance, the "truth" is determined by objective physical and chemical testing methods outlined in standards like ISO 4823, not by expert consensus on clinical cases.
4. Adjudication Method for the Test Set
Not applicable. Material performance tests are quantitative measurements (e.g., measuring dimensional change, tear strength) and do not involve human adjudication in the sense of reviewing cases.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size
No, an MRMC study was not done. This type of study is relevant for AI-powered diagnostic devices where human readers interpret medical images with and without AI assistance. This document is for a dental impression material, which is a physical product, not a diagnostic imaging tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
No, a standalone algorithm performance study was not applicable or performed. This device is a material, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for this device's performance is established by objective laboratory measurements dictated by the test methods in ISO 4823. This includes quantifiable properties like dimensional stability, tear strength, elastic recovery, etc., measured against the defined acceptance limits within the standard. It is not expert consensus, pathology, or outcomes data in the clinical sense.
8. The Sample Size for the Training Set
Not applicable. This device is a material, not a machine learning model; therefore, there is no "training set."
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.
