Adhese Universal DC is a dual-curing, single-component dental adhesive for enamel and dentin that is compatible with all etching techniques (self-etch, selective enamel etch, etch & rinse techniques). The areas of application include adhesive cementation of indirect restorations and direct restorative procedures. Adhese Universal DC is available in Free Stand Single Dose units. The applicator is coated with co-initiators required for the self-curing reaction. The initiator and adhesive are mixed together by dipping the applicator into the single dose unit containing the liquid Adhese Universal DC.
The report describes "Adhese Universal DC," a dual-curing dental adhesive. It uses the "Adhese Universal" (K133318) as its predicate device. The information provided heavily focuses on the comparison between the proposed device and the predicate device, especially regarding their working principles, chemical composition, and performance specifications.
Here's an analysis of the provided information concerning acceptance criteria and the study proving adherence:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Predicate: Adhese Universal) | Reported Device Performance (Adhese Universal DC) |
---|---|
Shear bond strength (Dentin): ≥25 MPa | Shear bond strength (Dentin): ≥20 MPa (Self-curing) |
Deviation Summary: The proposed device, Adhese Universal DC, has a lower acceptance criterion for shear bond strength (Dentin) at ≥20 MPa compared to the predicate's ≥25 MPa. This is explicitly noted in the document, attributing the lower value to the self-curing mode of Adhese Universal DC, which generally exhibits lower values.
2. Sample Size Used for the Test Set and Data Provenance
The document mentions "Bench testing was performed to test the physical property (shear bond strength)." However, it does not provide any specific sample sizes for this testing.
Regarding data provenance, the document does not specify the country of origin of the data. It indicates the testing was "Bench testing," implying laboratory-based testing, but does not clarify if it was retrospective or prospective in data collection approach.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
This information is not provided as the "test set" and "ground truth" concepts as typically applied to AI/software validation studies (with human experts evaluating outputs) are not relevant here. This is a material science study focused on physical properties, not diagnostic accuracy requiring expert consensus.
4. Adjudication Method for the Test Set
This is not applicable as the study is a bench test measuring physical properties, not a clinical trial or diagnostic accuracy study requiring adjudication of expert opinions.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size
This is not applicable. An MRMC study is relevant for assessing human reader performance in conjunction with AI. This document describes the performance of a dental adhesive, not an AI system.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This is not applicable. The device is a dental adhesive, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" in this context is the measured physical property of "Shear bond strength (Dentin)" obtained through laboratory bench testing according to established standards. It's an objective measurement rather than expert consensus, pathology, or outcomes data in the typical sense of AI/diagnostic studies.
8. The Sample Size for the Training Set
This is not applicable. The concept of a "training set" relates to machine learning models. This document describes a physical product, not a software algorithm.
9. How the Ground Truth for the Training Set Was Established
This is not applicable for the same reasons as #8.
Summary of the Study and How it Proves Acceptance Criteria:
The study proving the device meets its acceptance criteria is a non-clinical performance bench test. Specifically, it involved measuring the shear bond strength (Dentin) of the Adhese Universal DC in its self-curing mode.
The acceptance criterion for Adhese Universal DC's shear bond strength (Dentin) in self-curing mode was set at ≥20 MPa. While the document states that "The specification for Adhese Universal DC describes lower values (20 MPa) for shear bond strength (dentin) compared to Adhese Universal (25 MPa) due to the self-curing mode," it does not explicitly report the obtained value from the bench testing for Adhese Universal DC. It only states the specification. To definitively prove the device meets the acceptance criteria, the actual measured performance data of Adhese Universal DC on shear bond strength would need to be compared against the ≥20 MPa criterion. The document implies compliance through the "Summary of Performance Specification" which states, "The specification for Adhese Universal DC describes lower values (20 MPa) for shear bond strength (dentin) compared to Adhese Universal (25 MPa) due to the self-curing mode of Adhese Universal DC which generally shows lower values." This statement argues for the reason for the lower criterion but doesn't report the achieved value against that criterion.
The study also included Biocompatibility testing according to ISO 10993-1:2018, ISO 7405:2018, and ISO 14971:2012. The conclusion from this testing was that "The results of the Biocompatibility Assessment for Adhese Universal DC is substantially equivalent to the results of the Biocompatibility Assessment for the predicate device Adhese Universal." This demonstrates the device meets biocompatibility safety criteria by showing equivalence to a legally marketed predicate.
In essence, the study framework described is a comparative non-clinical bench study focusing on physical properties and biocompatibility to establish substantial equivalence to a predicate device for regulatory clearance.

Barrier Sleeves are intended to serve as a disposable barrier for dental instruments and equipment. This device is non-sterile and intended for single patient use only.
Barrier Sleeves are made of polyethylene film and are used as accessories to dental instruments and equipment used during dental procedures. These disposable barrier sleeves are offered in various shapes and sizes to fit over and cover the intended dental instruments and equipment. The disposable Barrier Sleeves slip over the ends of the respective devices, allowing for the attachment of the devices used during dental procedures. Barrier Sleeves act as a physical barrier, augmenting existing infection control techniques, and facilitate clean-up.
The provided text describes the 510(k) premarket notification for "Barrier Sleeves" by Ivoclar Vivadent, AG. This document focuses on demonstrating substantial equivalence to a predicate device, rather than proving a new device's independent efficacy through a "study that proves the device meets the acceptance criteria" in the context of, for example, an AI/ML medical device.
The "acceptance criteria" here are based on the similarity to the predicate device and meeting established performance standards for surgical drapes/barrier materials. The study described is a series of non-clinical bench tests and biocompatibility assessments.
Here's how to structure the information based on your request, with the understanding that this is not an AI/ML device study, but rather a traditional medical device submission for substantial equivalence:
Device: Barrier Sleeves (K191448)
Intended Use: "Barrier Sleeves are intended to serve as a disposable barrier for dental instruments and equipment. This device is non-sterile and intended for single patient use only."
The claim of substantial equivalence is supported by demonstrating that the Barrier Sleeves have the same intended use, fundamental technology, working principle, material composition, and comparable performance properties to the predicate device (Disposable Barrier Sleeves and Covers, K160232) manufactured by the same supplier.

Helioseal F Plus is used to seal fissures, pits and foramina caeca.
Helioseal® F Plus is a light-curing, white shaded fissure sealant featuring fluoride release. Helioseal F Plus is supplied in either a syringe or cavifil delivery form. The fissure sealant is composed of dimethacrylates. In the handling technique, the dental professional will clean the enamel surface to be sealed, isolate the working field, conditioning is performed, a thorough rinse and dry to remove the conditioner, before the application of Helioseal F Plus to the tooth surface.
This document is a 510(k) premarket notification for a dental device, specifically a pit and fissure sealant. It demonstrates substantial equivalence to a predicate device, rather than providing a performance study proving a device meets specific acceptance criteria as would be typical for an AI/ML medical device.
Therefore, the requested information regarding acceptance criteria, study design for AI/ML performance, sample sizes, expert involvement, ground truth establishment, and MRMC studies is not applicable to this document.
The document primarily focuses on demonstrating equivalence through:
- Comparison to Predicate Device: Detailed comparison of indications for use, contraindications, technology, principles of operation, and physical properties between Helioseal F Plus (subject device) and Helioseal F (predicate device).
- Bench Testing: Non-clinical performance testing for physical properties (flexural strength, curing depth, light intensity, wavelength for curing, water sorption, water solubility, radio-opacity) in accordance with FDA Guidance and EN ISO 6874:2015.
- Biocompatibility Testing: Evaluation for cytotoxicity and genotoxicity according to ISO 10993-1, ISO 7405, and ISO 14971.
The conclusion states that the devices are substantially equivalent, implying that the new device performs similarly to the already legally marketed predicate device. There are no acceptance criteria, in the sense of accuracy/recall/precision metrics for an AI/ML algorithm, or a human reader study, included in this type of submission.

- Inalys
- Onlays (e.g. occlusal veneers, partial crowns)
- Crowns in the anterior and posterior region
Tetric® CAD is a composite block for the fabrication of esthetic permanent inlays, onlays, veneers and crowns in the anterior and posterior region. Fabrication of the dental restoration is performed at the dentist's office in a compatible milling machine. The blocks are composed of cross-linked dimethacrylate and inorganic fillers. In the processing technique, the restoration is polished and seated after milling in the CAD/CAM system. The blocks are attached to a metal mandrel, the geometry of such is compatible with a milling machine, e.g. Cerec/InLab (Sirona), PlanMill (PlanMeca) or Programill One (Ivoclar Vivadent).
Tetric® CAD composite blocks are available in the translucency levels MT (5 shades - A1, A2, A3, A3.5, BL) and HT (4 shades 0 A1, A2, A3, A3.5), and in the sizes I12 and C14.
Here's an analysis of the provided text regarding the acceptance criteria and study for the Tetric® CAD device:
This document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a predicate device rather than presenting a standalone study with acceptance criteria for the new device's performance against specific clinical benchmarks. Therefore, much of the requested information regarding "acceptance criteria and the study that proves the device meets the acceptance criteria" in terms of clinical efficacy is not directly available in this type of submission. Instead, the focus is on showing similarity in functional performance and safety compared to an already approved device.
1. Table of Acceptance Criteria and Reported Device Performance
Given that this is a substantial equivalence claim, the "acceptance criteria" are implicitly that the new device (Tetric® CAD) performs comparably or better than the predicate device (Cerasmart K133824) for the listed physical properties. The data presented are for comparison.
Performance Metric | Acceptance Criteria (Implicit: Comparable to Predicate) | Reported Device Performance (Tetric® CAD) | Reported Predicate Performance (Cerasmart K133824) |
---|---|---|---|
Material Properties | |||
Flexural Strength | Comparable to predicate's 238 MPa | Typical mean value: 272 MPa | Brochure: 238 MPa |
Water Solubility | According to ISO 10477:2004 | Tested | Not explicitly stated (implied to meet standard) |
Biocompatibility | |||
Cytotoxicity | Non-cytotoxic (according to EN ISO 7405:2008 + A1:2013; ISO 10993-5:2009) | Non-cytotoxic | Evaluated according to ISO 10993-1:2009 |
Genotoxicity | Non-genotoxic (according to ISO 10993-3:2014) | Non-genotoxic | Not explicitly stated (implied to meet standard) |
Shelf Life | 36 months | 5 years | |
Storage Conditions | 2 - 28 °C / 36 - 82 °F, avoid sunlight | 4 - 25 °C / 39.2 - 77.0 °F, away from direct sunlight and high humidity |
Note on Acceptance Criteria: For a 510(k), "acceptance criteria" mainly revolve around demonstrating the new device is as safe and effective as the predicate. For physical properties, this usually means meeting or exceeding the predicate's performance when tested under relevant standards. The document explicitly states "the results of the bench testing show the products to be substantially equivalent," meaning the Tetric® CAD met the implicit acceptance criterion of being comparable.
The subsequent points (2-9) are largely not applicable or not explicitly detailed in the provided 510(k) summary because this document focuses on bench testing and biocompatibility for material properties and substantial equivalence, rather than clinical efficacy studies with human subjects.
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 for test set: Not explicitly stated for specific tests like flexural strength or water solubility in the summary. For ISO standard compliance (like ISO 10477 and ISO 6872), specific sample sizes are prescribed by the standards, but these aren't given in this summary.
- Data provenance: Not specified in the summary. This would typically be from the manufacturer's R&D labs.
- Retrospective or prospective: Not applicable for bench (non-clinical) testing.
The following points (3-6) are typically relevant for clinical studies, which are not detailed in this 510(k) summary for Tetric® CAD, as the focus is on material properties and substantial equivalence through bench 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. This pertains to clinical studies often involving expert review of images or patient outcomes. The provided document details bench testing of material properties and biocompatibility, which does not involve establishing ground truth by human experts in this manner.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable. This is for clinical studies with human assessors.
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 type of study is typically for diagnostic AI devices, not for dental restorative materials like Tetric® CAD.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. This refers to AI algorithm performance.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- For Flexural Strength and Water Solubility: The "ground truth" is established by the standardized measurement methods defined in ISO 6872:2015 and ISO 10477:2004, respectively.
- For Biocompatibility: The "ground truth" is determined by the results of specific in-vitro tests for cytotoxicity (EN ISO 7405:2008 + A1:2013; ISO 10993-5:2009) and genotoxicity (ISO 10993-3:2014), following the principles of ISO 10993-1:2009 + AC:2010.
8. The sample size for the training set
- Not Applicable. This is relevant for AI models. The document describes a material and its testing, not an AI system.
9. How the ground truth for the training set was established
- Not Applicable. This is relevant for AI models.
