Video: doctors implant tooth into eye, restore sight, creep everyone out
Osteo-odonto-keratoprosthesis. It's a real procedure that really does revive people's ability to see, yet we get the feeling that people will be more, um, excited about how it's done than why it's done. The seemingly Mary Shelley-inspired doctors extract a tooth from a blind person and drill a hole through it, where a prosthetic lens is placed, and the resulting macabre construction is implanted into the blind person's eye. The tooth is necessary as the body would reject an artificial base. It's not at all pretty, and it cannot repair every type of blindness, but it's still a major step forward. To hear from Sharron Thornton, the first American to have undergone the procedure, check the video after the break, but only if you can handle mildly graphic content -- you've been warned.

40 Second Toothbrush complicates, horrifies
We're not going to claim that the toothbrush can't be improved upon -- we know from experience that's not the case. But there is such a thing as going too far. The 40 Second Toothbrush, however, doesn't really claim to be more awesome than your standard stick-and-bristles affair -- just to be much, much faster. How does it cut the timesink of brushing the pearlies down by 66 percent? By having four intense-looking heads, which are capable of hitting up to six surfaces at once, at a rate of 810 swipes per minute. We haven't taken the thing for a spin ourselves, so we're not going to bother naysaying it, but we will say that it looks like a terrifying way to begin or end a day. The mouth violating 40 Second Toothbrush runs $99.95 from Hammacher Schlemmer and is available right now.[Via Red Ferret]
Cellphones are dangerous/not dangerous: leaky fillings edition
We're not even going to pretend we fully grasp what's going on here, but the long and short of Shiraz University of Medical Sciences' latest findings are that cellphones can trigger the release of mercury from one's fillings. Yes, seriously. The study asserts that out of 14 test subjects with fillings, those who used mobile phones had a statistically significant increase of mercury from urine tests than those who refrained from yapping. The science behind all of this is far beyond our IQ levels, but we're a little freaked out/not freaked out, regardless.[Via textually]
Osaka University develops teeth-controlled iPod interface
Just in case you weren't satisfied with the smorgasbord of options you already had when looking to control your iPod alternatively, researchers at Osaka University are hoping to shut you up. Thanks to new head gear that "uses infrared sensors and a microcomputer," individuals would be able to "operate music players by clenching their teeth." Essentially, the system "receives a command when the user clenches his or her teeth for about one second," which means that you can still chew gum and whatnot without getting it all confused. In the future, the team hopes to implement the technology into more devices, allowing folks to make funny faces to flip to the next slide in a presentation, answer a phone call, or even direct a wheelchair.
Ultreo toothbrush uses ultrasound, but can it clean teeth?
Riveting news from the world of dental hygiene: the Ultreo ultrasonic toothbrush has officially launched, promising what sounds like the ultimate brush session -- oh you know, "ultrasound waveguide technology" and "precisely tuned sonic bristle action" and stuff like that. Unlike traditional sonic units that only use audible frequencies of 20Hz to 20,000Hz, Ultreo uses a tuned sonic / ultrasonic (over 20,000Hz) combo to offer more enamel-rattling power without compromising the user's veneers, bridges, or general safety. There's a programmable replacement indicator that prompts a brush head switch-out every 3 months, and the 2-minute auto shut-off timer makes sure you don't cop out too early. For about $149.00, true tooth-o-philes can sink their chompers into this latest addition to the bourgie toothbrush market.[Thanks, Eric B]
Rocket develops "paper battery" for use with RFID, cosmetics
Nearly a year after NEC rolled out its paper-thin ORB batteries, Korean battery manufacturer Rocket is launching (ahem) its own uber-thin battery. While juicy, scientific details aren't readily available, we do know that the "paper battery" won't include any toxic chemicals, is "flexible and thin," and molds together the companies "thin film technologies" with its battery knowledge. The company hopes to entice heavy RFID users, smart card manufacturers, and "cosmetic / drug delivery system" providers to utilize the paper battery in powering the already-miniscule devices. Oddly, Rocket also envisions its new creation being used in "teeth whitening, anti-aging, and wrinkle care," though we're not exactly sure how electrifying a tooth will brighten your smile. Nevertheless, the company hopes to have its newfangled power source attached to crates and body parts real soon, and confidently assures us that it "doesn't cause explosions or fires." Phew.

New low-intensity pulsed ultrasound device helps re-grow teeth
We'd gladly trade in most of our gadgets if it meant we never had to go under the drill at the dentist again. But researchers at the University of Alberta in Canada don't want our electronics, they just want a few more years to perfect their low-intensity pulsed ultrasound (LIPUS) technology that they hope will ultimately be able to re-grow lost or severely damaged teeth from the root, eliminating the need for pricey prosthetics and painful procedures. The pea-sized device, which can be held in place by a bracket or a crown, is controlled by a wireless remote and needs to gently massage the gums for 20 minutes a day over the course of four weeks to attain noticeable growth. This tech isn't expected to be available to the public for another two years, so hold off on that all-candy and Red Bull diet you've been planning for just a little longer while you ponder the rather incredible possibility that this method could eventually be used to grow human bones and actually make people taller without subjecting them to any kind of medieval torture.
VELscope uses light to detect oral cancers
We're not too fond of trips to the dentist, for all the obvious reasons (plus the fact that we still can't get the image of Steve Martin as the sadistic tooth-ripper in "Little Shop of Horrors" out of our head). But if more tools like the VELscope come onto the market, we may just start checking in with the DDS more frequently. The device, developed by LED Dental in Vancouver, uses fluorescent light that hones in on tissues that glow when abnormal cells show up. That can give the dentist an edge in fighting cancers early on, before they progress too far. The device isn't on the market yet, but is expected to sell for about $5,000 when it's released. Now if they can just find a way to replace those drills with a similar tool, we're all set.
