Trade/Device Name: TopCEM Ceramic Primer Ceramic Coupling Agent Regulation Number: 21 CFR 872.3200
Agent Common name: Ceramic Coupling Agent Classification name: Agent, Tooth Bonding, Resin (21 CFR 872.3200
TopCEM Ceramic Primer Ceramic Coupling Agent serves as priming agent and is used to create a durable adhesion between luting composites and glass/oxide ceramic, metal, composite and fiberreinforced composite restorations.
TopCEM Ceramic Primer Ceramic Coupling Agent is common oral cementation repair auxiliary materials. In the process of using the product, TopCEM Ceramic Primer Ceramic Coupling Agent is placed between the prosthesis and resin adhesives, which can form the bonding layer of tooth tissue - light cure dental adhesive layer - resin cement layer - ceramic coupling agent - prosthesis, so as to achieve better bonding effect. TopCEM Ceramic Primer Ceramic Coupling Agent does not have direct contact with tooth tissue during use. TopCEM Ceramic Primer Ceramic Coupling Agent is mainly composed of silane coupling agent, acid acrylate and volatile organic solvent.
The provided document is a 510(k) Premarket Notification from the FDA for a dental bonding agent. It describes the device, its intended use, and compares it to a predicate device to establish substantial equivalence.
However, the document does not contain any information about a study that proves the device meets specific acceptance criteria based on performance metrics such as sensitivity, specificity, or accuracy, as would be expected for an AI/ML medical device. The device described is a "Ceramic Primer Ceramic Coupling Agent," which is a chemical product used in dentistry, not an AI/ML-driven diagnostic or prognostic device.
Therefore, I cannot provide the requested information regarding:
- A table of acceptance criteria and reported device performance (e.g., sensitivity, specificity, accuracy).
- Sample sizes for test sets or data provenance.
- Number of experts for ground truth establishment or their qualifications.
- Adjudication methods.
- MRMC comparative effectiveness studies or effect sizes.
- Standalone algorithm performance.
- Type of ground truth used (e.g., expert consensus, pathology, outcomes data).
- Sample size for the training set.
- How ground truth for the training set was established.
The document primarily focuses on non-clinical testing of physical properties and biocompatibility for a chemical product. It states:
- "Summary of Non-clinical testing": "The physical properties of the subject device, including Appearance, Solid Content, Bond Strength (MPa), Whether there are traces left on the glass panel surface, Packing Amount Tolerance and Detection of Infrared Characteristic Peaks, were determined and tested according to Internal standard SOP of the company, and the test results demonstrated the qualification and substantial equivalence when compared to the predicate device."
- "Summary of Clinical testing": "Clinical test is not applicable."
This indicates that the "acceptance criteria" and "proof" in this context relate to chemical and physical properties, and biocompatibility, as evaluated through internal SOPs and comparison to a predicate device, rather than the performance metrics typically associated with AI/ML diagnostic tools.

FineEtch - 10, 37 is a phosphoric acid (H3PO4) semi-gel-type agent intended for use on dentin and enamel. FineEtch will effectively remove the smear layer and help successful bonding.
The provided text is a 510(k) premarket notification for a dental etchant called "FineEtch." It discusses the device's classification, indications for use, comparison to a predicate device, and performance testing. However, it does not include the information requested regarding acceptance criteria and the study proving the device meets those criteria for an AI/ML device.
Specifically, the document states: "9. Performance Testing-Clinical tests Not Applicable". This indicates that no clinical studies, which would typically involve human subjects or human readers (as implied by questions 3-5), were conducted or submitted for this device. The non-clinical tests mention pH, viscosity, shape retention, and etching effect, comparing the device to a predicate and another dental etchant. This type of testing is characteristic of a substance or instrument, not an AI/ML diagnostic or assistive device that would rely on human expert interpretation of data.
Therefore, I cannot provide the requested information about acceptance criteria for an AI/ML device, ground truth establishment, expert consensus, MRMC studies, or training/test set details, as this document pertains to a chemical dental product, not an AI/ML software device.

Re: K240743
Trade/Device Name: Peak Universal Bond Regulation Number: 21 CFR 872.3200
Name: Resin tooth bonding agent Classification Name: Agent, Tooth Bonding, Resin Regulation Number: 872.3200
Use for virtually all etching and bonding needs in restorative dentistry for patients of all ages. Peak Universal Bond is used for desensitizing/sealing of tooth structure.
Peak Universal Bond adhesive bonds to the following materials:
- · Dentin and Enamel
- · Porcelain, Zirconia
- Metal
- · Composite
Peak™M Universal Bond is a bottle, syringe, or unit dose delivered bonding resin. It can be used with selfetch or with total etch techniques. It is 7.5% filled with an ethyl alcohol solvent carrier and will cure with most high intensity lights including LEDs. Peak Universal Bond adhesive contains 0.2% chlorhexidine which may ensure long term bond strengths. Its mode of action produces a mechanical occlusion of dentin tubules by the resins, thus reducing tooth hypersensitivity.
This is a 510(k) premarket notification for a resin tooth bonding agent, not an AI/ML device. Therefore, the requested information regarding acceptance criteria and study details for AI/ML performance is not found in this document.
The document discusses the substantial equivalence of the "Peak Universal Bond" device to a predicate device, focusing on its physical properties, technological characteristics, and indications for use in dentistry. It references non-clinical testing performed to establish this equivalence, specifically to ISO standards for bonding agents.
Here's why the requested information cannot be provided from this document:
- No AI/ML Component: The device, Peak Universal Bond, is a traditional medical device (a resin tooth bonding agent). It does not involve artificial intelligence or machine learning for diagnosis, prognosis, or treatment.
- Non-Clinical Testing: The "study" mentioned is "verification and validation testing" to show substantial equivalence. This involves testing physical properties according to ISO standards (e.g., ISO 29022 for shear bond strength, SEM imaging for dentinal tubule blockage) and simulated use by dental professionals. This is not a clinical study in the typical sense for AI/ML performance, nor does it generate the metrics you've requested.
Therefore, the specific points of inquiry about acceptance criteria, device performance, sample size for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, and ground truth types are not applicable and not present in this regulatory submission for a conventional dental bonding agent.

2. Sample Size and Data Provenance:
The document does not explicitly state the sample sizes used for the shear/tensile bond strength or fluoride release testing. It states that "certain tests were performed on this device, in comparison with the primary predicate device..." and references "the results of comparative study."
Regarding data provenance: The applicant, Kuraray Noritake Dental Inc., is based in Japan (1621 Sakazu, Kurashiki, Okayama 710-0801, Japan). The testing appears to be in-house testing performed by the manufacturer to demonstrate substantial equivalence, rather than a large-scale clinical trial with specific regional data. The document mentions "in-house standard" for compliance. The data is retrospective in the sense that it represents a snapshot of the device's performance at the time of submission.
3. Number of Experts and Qualifications:
The document does not mention the use of experts to establish ground truth for a test set. This type of submission relies on physical and chemical performance testing against defined quantitative criteria (e.g., bond strength in MPa). There were no human studies (e.g., diagnostic studies) mentioned that would require expert adjudication.
4. Adjudication Method:
Not applicable. As described above, this submission focuses on objective laboratory performance metrics, not human-read subjective assessments that would require adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
No MRMC study was conducted or mentioned. This is a dental bonding agent, not an AI-assisted diagnostic tool. Therefore, there's no concept of human readers improving with AI assistance.
6. Standalone Algorithm Performance:
Not applicable. This is a physical and chemical product, not a software algorithm.
7. Type of Ground Truth Used:
The "ground truth" for this device's performance evaluation is based on pre-defined quantitative performance metrics and physical/chemical properties established through laboratory testing. For example:
- Shear/Tensile Bond Strength: Measured values against a minimum acceptable MPa.
- Depth of Cure: Measured value against a minimum acceptable mm.
- pH: Measured value within a specified range.
- Appearance/Ease of Application/Occlusion of Dentinal Tubules: Qualitative assessment against defined criteria (e.g., "COMPLIES").

8. Sample Size for the Training Set:
Not applicable. This document describes a traditional medical device (dental material) and its performance validation, not a machine learning model that would require a training set.
9. How Ground Truth for Training Set Was Established:
Not applicable, as there is no training set for this type of device.

The document does mention performance data, but these refer to bench testing for a physical material, not an AI algorithm:
- Biocompatibility testing: Cytotoxicity, Sensitivity, Irritation, Acute Systemic toxicity, Genotoxicity (ISO standards)
- Non-clinical performance data (bench testing):
- Film thickness: ISO 4049:2010
- Shear bonding: ISO/TS 11405:2015; ISO29022:2013
- Light sensitivity: ISO 4049:2010
- Microleakage: ISO/TS 11405:2015
The text explicitly states:
- "Clinical performance data. This section is not applicable."
- "Software verification and validation testing. This section is not applicable."
- "Electrical safety and electromagnetic compatibility (EMC). This section is not applicable."
- "Mechanical and acoustic testing. This section is not applicable."
This further confirms that the device is not software-based or AI-enabled, and therefore, the requested information for AI/ML device evaluation is not present.
