## Indications for Use

The Perio Protect Tray is intended to be used to place solutions of the clinician's choice into gingival crevices or periodontal pockets. The design of the Perio Protect Tray permits placement of solutions deeper into the crevice/pocket than is possible with traditional fluoride trays. The choice of solution, the frequency of use, and the time the tray is to be in place are a part of the practice of dentistry, and are to be determined by the clinician.

## Device Story

Custom-fit dental tray fabricated from patient impressions; used by dental clinicians to deliver therapeutic solutions into gingival crevices or periodontal pockets. Unlike preformed fluoride trays, custom design allows deeper solution penetration into sulcus/pockets. Clinician determines solution type, frequency, and duration of use. Benefits include targeted site-specific delivery of oral medications to periodontal tissues.

## Clinical Evidence

Bench testing only. Performance demonstrated using sodium fluorescein dye mixed with hydrogen peroxide gel in the tray; dye observed in gingival sulcus 24 hours post-application. Retention force testing performed using a gram gauge to measure removal force (10 repetitions).

## Technological Characteristics

Custom-fit elastomeric dental tray. Designed for site-specific delivery of clinician-selected solutions to teeth and gingiva. Mechanical retention via custom fit.

## Regulatory Identification

A disposable fluoride tray is a device made of styrofoam intended to apply fluoride topically to the teeth. To use the tray, the patient bites down on the tray which has been filled with a fluoride solution.

#### 6. DEVICE TESTING

## PERFORMANCE DATA

- A. Data demonstrating different solutions used in the clinician's practice of dentistry are delivered to the teeth and surrounding tissues by use of the Perio Protect Tray.
Sodium Fluorescein dye was mixed in an aqueous solution and applied to the Perio Protect Tray with one drop of Peroxyl (hydrogen peroxide) gel. Sodium Fluorescein is a phosphorescent dye that can be illuminated under a black light.

The patients wore the trays 10 – 15 minutes in the morning and evening for one day. The patients were examined 24 hours later and a black light was used to illuminate the region around the teeth. Sodium fluorescein dye was observed in the gingival sulcus.

- B. The force necessary to remove the Perio Protect Tray was also tested.
Trays were also placed in the patient's mouth. A gram gauge was used to remove the tray from the patient's mouth. Each of these tests was repeated 10 times and an average of the force necessary to remove the tray was computed.

Dear Dr. Rosen:

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.

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.
