Device Description

Clinpro™ Varnish is a fluoride, calcium and phosphate containing coating for use in treating hypersensitive teeth and exposed dentin and root sensitivity. Clinpro™ Varnish is moisture and saliva-activated when applied to enamel and dentin. It will spread on and adhere to moist teeth. Clinpro™ Varnish is an alcohol/water-based solution of dental polymer resins. The product is sweetened with xylitol and sucralose. Clinpro™ Varnish contains two fluoride sources, 3% sodium fluoride and 3% strontium fluoride (equivalent to 2.26% fluoride ion). Clinpro™ Varnish provides both an initial release in the first hour and a continued release during the next 24 hours. Clinpro™ Varnish also contains sources of calcium and phosphate, including functionalized tri-calcium phosphate exclusively from 3M ESPE. Clinpro™ Varnish is supplied in unit-dose packages containing 0.50 ml of varnish coating. Each 0.50 ml of Clinpro™ Varnish contains 13.8 mg sodium fluoride and 13.8 mg strontium fluoride, equivalent to 10.4 mg total fluoride ion.

AI/ML Overview

The provided document describes the acceptance criteria and study for the Clinpro™ Varnish, a dental device. However, it's crucial to understand that this document is a 510(k) summary for a medical device and not a report for an AI/ML-based device. Therefore, many of the requested categories (like sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, etc.) are not applicable or not provided in this context.

The acceptance criteria here refer to the device's compliance with established safety and performance standards for its intended use, typically demonstrated through non-clinical (in vitro, biocompatibility) testing, and comparison to legally marketed predicate devices.

Here's the breakdown of the information as much as it can be extracted from the provided text:

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided in the document as it pertains to in vitro and biocompatibility testing, not human clinical trials with 'test sets' in the AI/ML sense. The in vitro tests likely involved dental models or extracted teeth. Biocompatibility tests would involve laboratory animals or in vitro cell cultures. The country of origin of the data is not specified, but the submission is from 3M Company in St. Paul, Minnesota, USA. The studies mentioned are non-clinical and would be prospective in their execution for the purpose of the 510(k) submission.

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)

This information is not applicable/provided. "Ground truth" in the context of this device refers to the physical and chemical properties and biological responses observed in the in vitro and biocompatibility tests, not interpretations by human experts for diagnostic accuracy.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable/provided. Adjudication methods are relevant for human interpretation tasks, not for the objective measurements of device performance in laboratory settings as described.

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 information is not applicable/provided. MRMC studies are for evaluating the performance of AI-assisted human interpretation in diagnostic tasks. This device is a dental varnish, not an AI/ML diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This information is not applicable/provided. This device is a physical product (dental varnish), not an algorithm.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

The "ground truth" for this device's performance is established through:

  • In vitro measurements: Objective laboratory measurements of dentin tubule penetration (evaluated via SEM and optical images) and fluoride, calcium, and phosphate release.
  • Biocompatibility testing: Standardized biological assessments demonstrating the device does not cause adverse biological reactions (e.g., cytotoxicity, irritation).
  • Comparison to predicate devices: The "ground truth" for substantial equivalence is that the device performs equivalently to existing, legally marketed similar devices that have established safety and effectiveness.

8. The sample size for the training set

This information is not applicable/provided. There is no "training set" in the context of this traditional medical device submission.

9. How the ground truth for the training set was established

This information is not applicable/provided. As there is no training set, there is no ground truth established for one.

Description of Device:

Clinpro™ Varnish is a fluoride, calcium and phosphate containing coating for use in treating hypersensitive teeth and exposed dentin and root sensitivity. Clinpro™ Varnish is moisture and saliva-activated when applied to enamel and dentin. It will spread on and adhere to moist teeth. Clinpro™ Varnish is an alcohol/water-based solution of dental polymer resins. The product is sweetened with xylitol and sucralose. Clinpro™ Varnish contains two fluoride sources, 3% sodium fluoride and 3% strontium fluoride (equivalent to 2.26% fluoride ion). Clinpro™ Varnish provides both an initial release in the first hour and a continued release during the next 24 hours. Clinpro™ Varnish also contains sources of calcium and phosphate, including functionalized tri-calcium phosphate exclusively from 3M ESPE. Clinpro™ Varnish is supplied in unit-dose packages containing 0.50 ml of varnish coating. Each 0.50 ml of Clinpro™ Varnish contains 13.8 mg sodium fluoride and 13.8 mg strontium fluoride, equivalent to 10.4 mg total fluoride ion.

Technological Characteristics:

The basic composition, fundamental technology and intended use of Clinpro™ Varnish are substantially equivalent to the predicate devices. Clinpro™ Varnish is a fluoride, calcium and phosphate containing coating to provide immediate and sustained relief of dental pain or hypersensitivity. The immediate relief of hypersensitivity is achieved by the hardened resin film that forms immediately after application and occludes the dentin tubules. Clinpro™ Varnish is unique formulation that utilizes novel resin polymer coating technology to incorporate the additional sources of fluoride, calcium and phosphate. In vitro fluoride release testing shows that Clinpro™ Varnish provides both an initial release in the first hour and a continued release during the next 24 hours.

  • The polymer resin varnish and the predicate rosin varnishes are film forming materials that block dentin tubules and act as carriers for the fluoride, calcium and phosphate. The synthetic polymer resin was selected due to its lower variability in composition and properties as compared to the naturally-sourced rosins and is substantially equivalent in performance to the rosin varnishes.

Performance Data:

In vitro testing was conducted with Clinpro™ Varnish and the predicate devices, Vanish™ 5% Sodium Fluoride White Varnish, Pulpdent® Active Varnish and Duraphat® 5% Sodium Fluoride Varnish. Properties evaluated include dentin tubule penetration and in vitro fluoride, calcium and phosphate release. SEM and optical images show that the devices form a thin film penetrating dentin tubules. In vitro fluoride release testing shows that Clinpro™ Varnish provides both an initial release in the first hour and a continued release during the next 24 hours. Clinpro™ Varnish utilizes a resin polymer coating technology to incorporate the additional sources of fluoride, calcium and phosphate as compared to the predicate devices that utilize a rosin polymer coating.

All varnishes function as film forming materials that block dentin tubules for use in treating dental hypersensitivity. Clinpro™ Varnish and Varnish™ Varnish are indicated for use on exposed dentin and root sensitivity for treating dental hypersensitivity as well.

Stability testing was conducted by evaluating the physical properties of the device at various storage conditions to confirm a shelf life at room temperature of 24 months. Biocompatibility testing for the device included cytotoxicity, sensitization, irritation/ intracutaneous reactivity and acute systemic toxicity.
