More Dental Oddities

Posted Jul 15 2009 8:11pm

Several new concepts to add to our ever-growing list of weird dental products:

Bluetooth in Your Tooth?

Our last post on weird dental products featured a Bluetooth mike that can be implanted in a tooth – presumably for people who like to talk on the phone a lot. Now an article in the latest issue of Medical Hypotheses posits another use for Bluetooth implants: caries prevention.

Caries is caused when the pH at the tooth surface drops below 5.5. A miniaturized and autonomous pH monitoring nodes can be attached to the tooth surface, like a tooth jewel. This intelligent sensor includes three components: (a) digital micro pH meter, (b) power supply, (c) wireless communicating device. The micro pH meter facilitates long term tooth surface pH monitoring and providing real time feedback to the patients and dental experts. Power supply of this system will be microfabricated biocatalytic fuel cell (enzymatic micro-battery) using organic compounds (e.g. formate or glucose) as the fuel to generate electricity. When micro pH meter detects the pH lower than 5.5, wireless Bluetooth device sends a caution (e.g. “you are at risk of dental caries”) to external monitoring equipment such as mobile phone or a hands-free heads. After reception of the caution, subjects should use routine brushing and flossing procedure or use a medicated chewing gum (e.g. chlorhexidine containing chewing gum) or rinse with a mouthwash.

On the one hand, this is a fascinating application of technology. On the other, we still seriously question the wisdom of implanting a frequency-emitting device in a living tooth.

Smile…You’re on Plaque Cam!

It’s one thing to get people to brush and floss, but quite another to be sure they do so effectively. Would it help if they could see up close just how much biofilm and other gunk is on their teeth? The makers of the Miharu Dental Intraoral Plaque Detection Camera seem to think so.

Yes, you, too, can have a mouth cam of your very own…and for only $119 plus shipping. Your oral microbes at work: just what you wanted to watch on TV tonight, right?

Soda that Doesn’t Rot Your Teeth?

That’s the dream of a trio of researchers who envision a soft drink that actually promotes tooth health.

A tooth friendly soft drink (T.F.S.D) should have the following characteristics and elements; fluoride (approximately 1ppm), casein phosphopeptide–amorphous calcium phosphate (2%), xylitol (4–6g/serving), tea polyphenols (2–4mg/ml), cranberry extract (250mg/ml of the flavonoids quercetin and myricetin), sugar free, pH close to 5.5 and super oxygenation (240,000ppm) vs. carbonation. T.F.S.D can be packaged in a container which gaseous oxygen is dissolved in a liquid in the form of bubbles. However, looking at opportunities for so-called sophisticated soft drinks, T.F.S.D will be an example for a functional and health oriented soft drink.

In other words, don’t expect such a “functional food” to replace Coke anytime soon.
