RARE! Dr. Woog PlakTest
Vintage 1978 Dental Plaque Detector
formerly known as Broxo Test

The Broxo Company was founded in 1956 by Dr. Phillippe Guy E. Woog who pioneered the development of the electric toothbrush in 1954. The Broxodent toothbrush was introduced by Squibb Pharmaceutical at the Centennial Congress of the American Dental Association in New York City in 1959. Dr. Woog had other inventions, such as the fluorescein based plaque detector, US Patent 4184196, filed in 1976.

us.broxo.com / about-us . The Broxo company is now a part of Swiss Healthcare Solutions Sarl, Geneva, Switzerland.

The device is in very good to excellent cosmetic and WORKING condition for its 1978 vintage. It consists of a fluorescein reservoir and dispenser at one end. It has a built-in valve that is tightly closed when the dispensing tip is "down" (flush with the reservoir) and open when the top is "vertical" or "up." The big white button (see photo) applies slight pressure to the plastic reservoir to squeeze out one drop. There is a battery compartment (which takes 3 AA batteries, not included) at the other end. It is in clean, almost like new condition. The unit was never stored with batteries therein and there is no corrosion. There is a mirror lid and filtered light source in the middle. The blue light is filtered white light. THE LIGHT IS NOT A UV (ultraviolet) LIGHT. NO UV!

The light goes on automatically via a mechanical switch when the mirror lid is popped open. It goes off automatically when the lid is snapped closed.

A drop of fluorescein solution is swished in the mouth. The teeth are observed in the mirror lid as the blue light shines upon them. Fluorescein does not adhere to clean tooth enamel which will reflect the blue light and appear blue. Fluorescein does adhere to bacteria and plaque and will appear yellow due to the yellow fluorescence.

The original 8.5" x 5.5" instruction sheet (printed on both sides) is included. This unit comes with a nearly full reservoir of fluorescein and should last a long time. Fluorescein solution is used in medicine (orally and topically) and used to be available from local pharmacists, albeit usually by special order or request. Today, chain pharmacists (CVS, Walgreens, et al.) might not want to order it for you but you can ask. You might have to ask a compounding or specialty pharmacy to order more. USP or pharmaceutical grade fluorescein solution is also available on the internet or from medical and science supply companies.

The device is 5 inches x 2.5 inches x 1 inch. (There is parallax in the photos which throws off the ruler readings.) Because of the needed distances and angles, I couldn't get photos of the PlakTest in use. The object (teeth) is held within 6" - 8" from the blue light + mirror. Blue light reflects off of the teeth which are viewed in the mirror. I couldn't get a camera angle to show the reflection of teeth or other test object without either blocking the blue light or blocking the reflected yellow light.

I have not seen another one of these plaque disclosing devices in many years (decades). I think it is a one of a kind item. RARE!
