DURASHIELD® PLUS is indicated for the relief of dental hypersensitivity where dentin and cementum are exposed.
DURASHIELD® PLUS is a topically applied, flavored cavity varnish containing sodium fluoride and NovaMin. The varnish is a viscous liquid and is insoluble in water and saliva. NovaMin is a bio-available calcium phosphosilicate that releases calcium and phosphorous when exposed to moisture.
The provided text (K082198) is a 510(k) premarket notification for a dental product called DURASHIELD® PLUS. This type of regulatory submission focuses on demonstrating substantial equivalence to a predicate device, rather than proving efficacy through clinical trials with specified acceptance criteria and performance data.
Therefore, the document does not contain the information requested in the prompt regarding acceptance criteria, study details, sample sizes, expert ground truth establishment, adjudication methods, MRMC studies, standalone performance, or training set details.
The submission primarily discusses:
- Device Name: DURASHIELD® PLUS
- Predicate Device: Sci-Pharm DFV Varnish
- Description: A topically applied, flavored cavity varnish containing sodium fluoride and NovaMin.
- Intended Use: Relief of dental hypersensitivity where dentin and cementum are exposed.
- Technological Characteristics: Similar to predicate device, with the addition of NovaMin for remineralization.
- Non-Clinical Performance Data: Components of DURASHIELD® PLUS passed biocompatibility testing; no additional biocompatibility tests were conducted for the final product.
- Conclusion: Substantially equivalent to the predicate device.
For medical devices, particularly those seeking 510(k) clearance, the focus is on demonstrating that the new device is as safe and effective as a legally marketed predicate device, not necessarily on meeting specific performance metrics from a de novo study. The FDA's letter confirms substantial equivalence, allowing the device to be marketed.

ର. Substantial Equivalence:
Technological Characteristics.
The technological characteristics (i.e., chemical composition and device function) of DURASHIELD® PLUS are similar to that of Sci-Pharm DFV Varnish and other cavity varnishes that have been in widespread use for many decades. The only difference is that DURASHIELD® PLUS contains NovaMin, which naturally remineralizes teeth.
Non-Clinical Performance Data.
Prior use of the components of DURASHIELD® PLUS have been evaluated and passed biocompatibility testing for oral toxicity. Therefore, no additional biocompatibility tests were conducted.
Conclusion as to Substantial Equivalence
DURASHIELD® PLUS with NovaMin is substantially equivalent to the current Sci-Pharm DFV Varnish in terms of intended use, physical properties and materials. The purpose of this submission is to introduce a cavity varnish with NovaMin.

Dear Ms. Lewis:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the 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, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at (240) 276-0115.
