Baby tooth stem cells could regrow kids' dental tissue
If you injure a tooth as a kid, there's a real chance you'll grow up with a 'dead' tooth whose roots didn't grow properly due to tissue damage. However, scientists have conducted a successful trial for a method that could regrow kids' dental tissue using stem cells from their baby teeth. The team extracted human deciduous pulp stem cells (hDPSC) from patients' healthy baby teeth, allowed the cells to reproduce in a lab culture, and implanted them in the injured teeth. A year later, enough healthy tissue had regrown that the kids could feel at least some sensations, such as hot or cold.
Disney can digitally recreate your teeth
Digital models of humans can be uncannily accurate these days, but there's at least one area where they fall short: teeth. Unless you're willing to scan the inside of someone's mouth, you aren't going to get a very faithful representation of someone's pearly whites. Disney Research and ETH Zurich, however, have a far easier solution. They've just developed a technique to digitally recreate teeth beyond the gum line using little more than source data and everyday imagery. The team used 86 3D scans to create a model for an "average" set of teeth, and wrote an algorithm that adapts that model based on what it sees in the contours of teeth in photos and videos.
Regenerative tooth fillings could put an end to root canals
You really don't want a root canal, and not just because it's potentially painful. Emptying the tooth of the infected tissue at its heart potentially weakens it, since you can't grow that organic material back or put toxic fillings in its place. Researchers may have a solution, though. They've crafted fillings that get the tooth's own stem cells to regenerate and repair tissue. This doesn't mean that your pearly whites would return to normal, but the substance could heal the tooth enough to spare you a root canal or prevent fillings from going south.

Researchers hope tooth regeneration gel will reduce the need for fillings
We may still not have jetpacks or flying cars, but it looks like the 21st century might be about to get a bit more futuristic. As Discovery News reports, a study published in the ACS Nano journal is offering some fairly convincing evidence that a new type of hormone gel could potentially regenerate teeth and eliminate the need for fillings in at least some cases. According to the French scientists behind it, the gel has already managed to make cavities in mice "disappear" after only a month, and the peptide used in the gel, MSH, has also previously been shown to encourage bone regeneration. Of course, it will be a little while yet before your dentist puts down the drill -- the researchers say there still needs to be "several years" of clinical trials, and note that it likely won't replace fillings altogether (or prevent them).
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.

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.

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.
