SciPharm's DFV Desensitizing Varnish is a fluoride-containing resin preparation for the treatment of dentinal hypersensitivity and for the reduction of post-operative sensitivity.
SciPharm's DFV Desensitizing Varnish is a device that consists of a synthetic compound from a natural rosin that is intended to coat a prepared tooth cavity prior to the insertion of a restorative material by forming a film that facilitates occlusion of compromised surfaces, including open dentinal tubules. DFV Desensitizing Varnish and the predicate device consist of a viscous liquid that can be applied to the teeth using a brush or similar applicator. The purpose of the 5% sodium fluoride as the source of fluoride ions for the formation of calcium fluoride, and along with the rosin, occludes the dentin tubules. Both use denatured alcohol (ethanol) as a significant component, providing fluidity for application and to promote quick drying on the tooth surface.
SciPharm's DFV Desensitizing Varnish is a topically applied, flavored (Strawberry, Bubblegum, Spearmint, Chocolate, and Marshmallow) topical varnish containing sodium fluoride on a synthetic rosin based preparation from a natural rosin. Only a professional clinician may apply DFV Desensitizing Varnish. The varnish and applicator are packaged in a thermoformed PET/PVC opaque unit dose tray, and sealed with foil.
The provided document is a 510(k) summary for a medical device called DFV Desensitizing Varnish. It details the device's properties, intended use, and comparison to predicate devices, including performance data.
Here's an analysis of the acceptance criteria and study information:
1. Table of Acceptance Criteria & Reported Device Performance
The document does not explicitly state "acceptance criteria" in a pass/fail sense with numerical thresholds for performance. Instead, it presents a comparison of the proposed device (DFV Desensitizing Varnish) with an "Equivalent Varnish" (presumably a predicate device or a similar product used for internal comparison) across several physical and chemical tests. The implicit acceptance criteria are that the DFV Desensitizing Varnish should perform comparably or better than the equivalent device.
| Test | Proposed DFV Desensitizing Varnish | Equivalent Varnish | Reported Device Performance (DFV) | Comments |
|---|---|---|---|---|
| Contamination | No Foreign Particles | No Foreign Particles | No Foreign Particles | Meets the comparative standard. |
| Color | Match Standard | Match Standard | Match Standard | Meets the comparative standard. Further context on what "standard" refers to is not provided, but it implies internal consistency. |
| Odor | Match Standard | Match Standard | Match Standard | Meets the comparative standard. Similar to Color, "standard" is internal. |
| Viscosity | 4500 – 6500 cps | 7000 – 8500 cps | 4500 – 6500 cps | The proposed device has a different, lower viscosity. The document does not provide context on why this difference is acceptable, but it implies it's within an acceptable range for the intended application. |
| Non-Pyrolizable % | 7.5% - 8.7% | 8.4% - 9.5% | 7.5% - 8.7% | The proposed device has a slightly lower range for non-pyrolizable percentage. Similar to viscosity, acceptability is implicit. |
| Fluoride Content | 4.5% - 5.5% NaF (2.0% - 2.5% F) | 4.5% - 5.5% NaF (2.0% - 2.5% F) | 4.5% - 5.5% NaF (2.0% - 2.5% F) | Exactly matches the equivalent varnish, which is a key performance metric for a fluoride varnish. |
| Cytotoxicity | 11% cell viability (Toxicon Report 17-04113-G1) | 11% cell viability (Toxicon Report 18-00602-G1) | 11% cell viability | Both devices showed 11% cell viability, which is below the 70% threshold. The document explains this is expected due to ingredients like ethanol and sodium fluoride, and is considered acceptable as it's consistent with existing approved varnishes. |
| Dentin Tubule Occlusion (SEM) | Smooth with minimal surface defects | Subsurface porosity and heterogeneity | Smooth with minimal surface defects | The proposed device demonstrated a "thick uniform film with fewer defects and protrusions" than the competitor's varnish, suggesting better performance in this aspect. |
| Shelf Life | Stable for at least 24 months | Not specified | Stable for at least 24 months | Demonstrated stability through internal testing (Report 2019-R-012). |
2. Sample Size Used for the Test Set and Data Provenance
- Cytotoxicity Test: Not explicitly stated for either the DFV Desensitizing Varnish or the equivalent device. It refers to "L929 cells." The provenance is not specified beyond being generated by "Toxicon Report 17-04113-G1" and "Toxicon Report 18-00602-G1."
- Dentin Tubule Occlusion (SEM): Refers to "Disk-shaped human dentine specimens." The exact number of specimens/samples is not specified. The provenance (e.g., country) is not mentioned.
- Physical Tests (Contamination, Color, Odor, Viscosity, Non-Pyrolizable %, Fluoride Content): The sample size for these tests is not specified.
- Shelf Life: Not specified, but implied to be multiple units tested over time intervals (Time 0, 6 months, 12 months, 18 months, etc.) for up to 4 years.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
- No expert adjudication is mentioned or implied for these performance tests. The tests are laboratory-based and objective (e.g., cell viability percentage, SEM imaging, chemical concentration measurements).
4. Adjudication Method for the Test Set
- None. As the tests are objective laboratory measurements, there is no need for expert adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
- Not applicable. This device is a cavity varnish, not an AI-powered diagnostic or assistive technology. It does not involve human readers interpreting cases or AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Not applicable. As above, this is not an AI-powered device. Performance is measured directly from the physical and chemical properties of the varnish.
7. The Type of Ground Truth Used
- Cytotoxicity: Measured cell viability against a control and compared to a 70% threshold (ISO 10993-5 and ISO 7405 standards).
- Dentin Tubule Occlusion (SEM): Direct microscopic observation and characterization of the film formed on dentine specimens.
- Physical/Chemical Tests: Laboratory measurements against internal "standards" or specifications (e.g., specific viscosity range, fluoride content percentage).
- Shelf Life: Stability over time judged by changes in contamination, color, viscosity, fluoride content, nonpyrolizable percentage, and odor against acceptable ranges.
8. The Sample Size for the Training Set
- Not applicable. This device is a pharmaceutical product (dental varnish), not a machine learning model, so there is no concept of a "training set" for model development.
9. How the Ground Truth for the Training Set Was Established
- Not applicable. As there is no training set for a machine learning model, this question does not apply.

Eugenone is a eugenol-free temporary cement used in the placement of temporary or temporary placement of permanent prostheses.
Eugenone is a eugenol-free temporary cement.
This document is a 510(k) premarket notification decision letter from the FDA for a dental cement named "Eugenone." It's not a study report, and therefore, it does not contain the detailed information requested regarding acceptance criteria and performance studies for a device.
The letter explicitly states: "We have reviewed your Section 510(k) premarket notification of intent to market the device... and have determined that this device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976..."
This indicates that the device was cleared based on substantial equivalence to existing predicate devices, rather than through a new clinical performance study that would generate the kind of data you're asking for.
Therefore, I cannot provide the requested information for the following reasons:
- Acceptance criteria and reported device performance: This document does not specify formal acceptance criteria for a new study, nor does it report on the device's performance against such criteria. The clearance is based on equivalence.
- Sample size, data provenance: No new study data is provided, so these details are not available.
- Number of experts, qualifications, adjudication method, ground truth type: These are all details related to a clinical study establishing ground truth, which is not present in this regulatory clearance document.
- MRMC comparative effectiveness study: This is not mentioned as part of the review for substantial equivalence.
- Standalone performance: Not applicable as no new performance study is detailed.
- Training set sample size and ground truth establishment: Not applicable as this is not a study report with distinct training and test sets.
In summary, the provided document is a regulatory clearance letter, not a technical report detailing a performance study.

Proviso™ is a self-cured material that is intended for the fabrication of temporary crowns and bridges.
Not Found
This document is a 510(k) clearance letter from the FDA for a dental device called Proviso™. It establishes substantial equivalence to a predicate device, which allows the new device to be marketed. However, this document does not contain any information about acceptance criteria or a study that proves the device meets those criteria.
The 510(k) process primarily relies on demonstrating that a new device is "substantially equivalent" to a legally marketed predicate device, meaning it has the same intended use and the same technological characteristics as the predicate, or, if it has different technological characteristics, it does not raise different questions of safety and effectiveness and is as safe and effective as the predicate device. This often involves comparing performance characteristics to the predicate, but the specific details of such comparative testing or acceptance criteria are typically found in the 510(k) submission itself, not in the clearance letter.
Therefore, I cannot provide the requested information based on the provided text. The document states: "We have reviewed your Section 510(k) premarket notification of intent to market the device we have determined the device is substantially equivalent...". This indicates the FDA reviewed data, but the data itself is not presented here.
To answer your questions, I would need to review the actual 510(k) submission document, which would detail the performance data, acceptance criteria, and specific studies conducted.

For use as a varnish on sensitive teeth over exposed dentin and under temporary restoratives and cements.
The varnish has the consistency of a viscous liquid. When applied in a thin layer over tooth dentin, the solvent (ethyl alcohol and water) evaporates within a few minutes, leaving a film of Colophony resin in which Sodium Fluoride is suspended, which adheres well to the tooth structure.
This document focuses on the substantial equivalence of the Sci-Pharm DFV Varnish to legally marketed predicate devices, rather than establishing acceptance criteria or performance through a clinical study with numerical metrics like sensitivity, specificity, or accuracy.
The manufacturer, Scientific Pharmaceuticals, Inc., sought 510(k) clearance from the FDA for their Sci-Pharm DFV Varnish. The clearance relies on demonstrating that the new device is as safe and effective as a legally marketed predicate device, not on meeting specific, pre-defined acceptance criteria through a clinical performance study.
Here's an analysis based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
This type of table is not directly applicable here because the submission is based on substantial equivalence, not a performance study against specific acceptance criteria. Instead, the document compares the chemical composition and device function to predicate devices.
| Feature / Criterion | Predicate Device (Duraphat/Durafluor) | Sci-Pharm DFV Varnish Performance |
|---|---|---|
| Material/Composition | ||
| Ethyl Alcohol | 75% | 71.25% |

| Solvent Type | Pure ethyl alcohol | Azeotrope of ethyl alcohol and water (95:5 ratio) |
| Cure Speed | Standard | Faster cure |
| Potential for initial irritation | Standard | Reduced potential |
2. Sample Sizes and Data Provenance
This information is not applicable as there was no formal "test set" in the context of a clinical performance study. The data provenance relates to the analysis of the chemical composition and physical properties of the Sci-Pharm DFV Varnish and its predicate devices.
- Sample Size for Test Set: Not applicable (no clinical test set for performance metrics).
- Data Provenance: The data regarding chemical composition and physical properties were likely generated in-house by Scientific Pharmaceuticals, Inc., through laboratory tests (IR spectrophotometry, pyrolysis, viscosity and refractive index measurements, dry residue determination). The document doesn't specify if these were retrospective or prospective analyses, but they would have been performed specifically for the 510(k) submission.
3. Number and Qualifications of Experts for Ground Truth
This is not applicable. Ground truth, in the sense of expert consensus on clinical diagnoses or outcomes, was not required for this type of submission. The "ground truth" here is the established chemical composition and functional behavior of the predicate devices and the Sci-Pharm DFV Varnish, determined through analytical laboratory techniques.
4. Adjudication Method
This is not applicable. There was no adjudication method used as this was not a clinical study involving human assessment of outcomes.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No, an MRMC comparative effectiveness study was not done. This type of study assesses the impact of a device (often AI) on human reader performance, which is not relevant to a 510(k) submission for substantial equivalence of a dental varnish.
6. Standalone (Algorithm Only) Performance Study
No, a standalone study was not done. This submission is for a physical dental varnish, not an algorithm or software. The closest analogy would be the in-lab testing of the varnish's chemical and physical properties to demonstrate its equivalence.
7. Type of Ground Truth Used
The "ground truth" used for this submission was based on:
- Chemical Analysis: Laboratory results from techniques like IR spectrophotometry, pyrolysis, viscosity and refractive index measurements, and dry residue determination to confirm the identity and concentration of ingredients in both the new device and the predicate devices.
- Established Device Function: The document refers to the "accepted worldwide" uses of varnishes with similar compositions, indicating an reliance on existing clinical understanding and historical data for this class of devices.
8. Sample Size for the Training Set
This is not applicable as this is not an AI/machine learning device requiring a training set.
9. How the Ground Truth for the Training Set Was Established
This is not applicable for the same reason as above.
