(125 days)
- Direct dental restorations (e.g., resin-based composites, resin-modified glass ionomers, resin core build-ups, compomers).
- Indirect dental restorations (e.g., metal, resin-based composite, dental ceramics such as porcelain, pressed ceramic, lithium disilicate, lithium silicate or zirconia).
- Desensitization of dentin.
- Sealing of dentin, cementum or enamel.
The Parkell® Universal Adhesive is a single-component, one-bottle, light-cured universal bonding agent which utilizes proven 4-META and 10-MDP chemistry to enhance penetration into prepared enamel and dentin surfaces and to establish strong bonds to dental surfaces such as restorative composites, metals, dentin, enamel, cementum, and dental ceramics (e.g., porcelain, lithium disilicate, zirconia, or hybrid ceramics). The Device is useful for all direct and indirect dental restorations, desensitizing teeth, and sealing tooth structures against microleakage. Moreover, the Device can be used without prior acid-etching of dentin or cutting of enamel surfaces.
The Parkell® Universal Adhesive will be provided in a single bottle, with standard applicator brushes for applying the adhesive to treatment surfaces.
The provided document is a 510(k) premarket notification for the "Parkell® Universal Adhesive" and primarily focuses on demonstrating substantial equivalence to a predicate device, the "Scotchbond® Universal Adhesive."
Here's an analysis of the acceptance criteria and study information based on the document:
1. Table of Acceptance Criteria and Reported Device Performance:
The document states that the acceptance criterion for Shear Bond Strength is "at least about 6MPa" (denoted as "<::6MPa", which likely means "greater than or equal to 6 MPa"). The reported device performance is compared in Table 5-A, summarized here:
| Material Type | Acceptance Criteria (Shear Bond Strength, Initial) | Parkell® Universal Adhesive (Reported Performance) | Predicate Device (Scotchbond® Universal Adhesive) (Reported Performance) |
|---|---|---|---|
| Enamel | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Dentin | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Silver alloy | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Cobalt-chrome alloy | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Porcelain, following acid etching | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Porcelain, following sandblasting | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Lithium disilicate, following sandblasting | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Lithium disilicate, following HF acid etching | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Zirconia, following sandblasting | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Composite Resin (self-cure) | >= 6 MPa | >= 6 MPa | >= 6 MPa |
| Composite Resin (light-cure) | >= 6 MPa | >= 6 MPa | >= 6 MPa |
2. Sample size used for the test set and the data provenance:
The document does not explicitly state the sample size used for each shear bond strength test. It mentions that tests were performed "on a variety of dental substrates." The data provenance is not specified (e.g., country of origin, retrospective or prospective), but it's implied to be laboratory testing as part of a premarket notification for a dental adhesive.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This information is not applicable as the study described is a laboratory performance test (shear bond strength) for a dental adhesive, not a study involving expert-derived ground truth. The "ground truth" here is the physical measurement of bond strength.
4. Adjudication method for the test set:
This information is not applicable for the same reason as 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:
This is not applicable. The device is a dental adhesive, not an AI-powered diagnostic or assistive tool for human readers.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
This is not applicable. The device is a physical product (dental adhesive), not an algorithm. The shear bond strength tests are a form of standalone performance evaluation for the physical properties of the adhesive.
7. The type of ground truth used:
The "ground truth" for the performance evaluation of the dental adhesive is based on physical measurement of shear bond strength in a laboratory setting, in accordance with ISO standards.
8. The sample size for the training set:
This is not applicable. The device is a physical product (dental adhesive), not a machine learning model that requires a training set.
9. How the ground truth for the training set was established:
This is not applicable for the same reason as point 8.

- Predicate Device:
Scotchbond® Universal Adhesive (K110302)/(3M ESPE)
- Predicate Device:
-
- Description of Proposed Device:
The Parkell® Universal Adhesive is a single-component, one-bottle, light-cured universal bonding agent which utilizes proven 4-META and 10-MDP chemistry to enhance penetration into prepared enamel and dentin surfaces and to establish strong bonds to dental surfaces such as restorative composites, metals, dentin, enamel, cementum, and dental ceramics (e.g., porcelain, lithium disilicate, zirconia, or hybrid ceramics). The Device is useful for all direct and indirect dental restorations, desensitizing teeth, and sealing tooth structures against microleakage. Moreover, the Device can be used without prior acid-etching of dentin or cutting of enamel surfaces.
- Description of Proposed Device:
The Parkell® Universal Adhesive will be provided in a single bottle, with standard applicator brushes for applying the adhesive to treatment surfaces.
-
- Intended Use:
- Direct dental restorations (e.g., resin-based composites, resin-modified glass ionomers, ﮯ resin core build-ups, compomers).
- ನ Indirect dental restorations (e.g., metal, resin-based composite, dental ceramics such as porcelain, pressed ceramic, lithium disilicate, lithium silicate or zirconia).
- ನ Desensitization of dentin.
- Sealing of dentin, cementum or enamel. ব
As so described and as demonstrated in Table 5-A, the Device has the same intended uses as the Predicate Device (Scotchbond™ Universal Adhesive, 510K no. 110302, which has been marketed since about 2011), in that both devices are useful for direct and indirect dental restorations (e.g., inlays, onlays, crowns, bridges, varnishes and veneers), desensitizing

teeth and root surfaces, and sealing tooth structures and cavities. Any differences in the descriptions of intended uses of the Device and Predicate Device, to the extent that they exist, are minor, not critical to the intended therapeutic uses of the Device, and do not affect the safety and/or effectiveness of the Device when used as labeled.
8. Technological Characteristics:
The proposed device, Parkell® Universal Adhesive, has the same intended use and contains similar chemical components to that of the predicate device (Scotchbond™ Universal Adhesive, K110302). The proposed device and its predicate both contain several of the same chemical components as well as identical functional categories of components, with the exception of a "filler" which is included only in the Predicate Device. The differences in chemical composition across the Device and Predicate Device are believed to have insubstantial effects on the intended use of the Device. This is evidenced by substantially similar performance by the proposed device and predicate devices in performance tests on a variety of dental substrates, as described in the device comparison table below.
Most importantly, all chemical components found in the proposed Device, but not within the Predicate Device, are commonly-used chemicals that are present in many FDA-cleared dental products which have long histories of safe use.
9. Biocompatibility:
An evaluation of biocompatibility was conducted to determine the safety of Parkell® Universal Adhesive in accordance with ISO 10993-1:2009, ISO 10993-3:2014, ISO 10993-5: 2009, ISO 10993-10:2010, ISO 10993-12: 2012, ISO 10993-33:2015, and the Final FDA Guidance, "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" (June 16, 2016). The conclusion of the evaluation is that Parkell® Universal Adhesive can be considered biocompatible.
10. Substantial Equivalence2:
Information provided in this 510(k) submission demonstrates that Parkell® Universal Adhesive is substantially equivalent to the Predicate Device, 3M ESPE's Scotchbond® Universal Adhesive (K110302) in terms of bond strength to dentin, enamel,metals, composite resins, and dental ceramics. The shear bond strength tests were performed in accordance with ISO standards. The bond strengths achieved by the Device were compared to that of the Predicate Device and were determined to be equivalent.
Any differences between the Device and the Predicate Device, for purposes of this 510(k) submission, do not raise new questions of safety or effectiveness. Thus, this submission demonstrates the safety and effectiveness of Parkell® Universal Adhesive. A brief comparison of Parkell® Universal Adhesive to the Predicate Device is provided below:
All statements contained herein are made solely for the purpose of demonstrating substantial equivalence as that term is defined in the context of SIO(k) submissions; the statements cannot be applied reliably or accurately in the context of U.S. patent or other intellectual property laws which involve vastly different legal standards and definitions (such as, e.g., within the context of 35 U.S.C. §§ 102, 103, 112, 271).
