Science Daily [2011-01-22] -Cracking a Tooth: 3-D Map of Atoms Sheds Light on Nanoscale Interfaces in Teeth, May Aid Materials Design.
Teeth and bone are important and complex structures in humans and other animals, but little is actually known
about their chemical structure at the atomic scale. What exactly gives them their renowned toughness, hardness and strength? How do organisms control the synthesis of these advanced functional composites?
Now, using a highly sophisticated atomic-scale imaging tool on a sea creature’s tooth, two Northwestern University researchers have peeled away some of the mystery of organic/inorganic interfaces that are at the heart of tooth and bone structure. They are the first to produce a three-dimensional map of the location and identity of millions of individual atoms in the complex hybrid material that allows the animal to literally chew rock.

Botox for Dentists?
Why would dentist want to use Botox?
A little bit of history. According to Wikipedia, Botulinum toxin is a protein produced by the bacterium Clostridium botulinum, and is extremely neurotoxic. When introduced intravenously in monkeys, type A of the toxin exhibits an LD50 of 40-56 ng, type C1 around 32 ng, type D 3200 ng, and type E 88 ng, rendering the above types some of the most powerful neurotoxins known.Popularly known by one of its trade names, Botox or Dysport, it is used for various cosmetic and medical procedures.
The Tennessee Board of Dentistry is considering a rule change that would allow dentists to treat their patients with the drug.
The board has already given the okay to oral surgeons. They can start using Botox Thursday to help treat jaw pain and discomfort.

Dental SEO Marketing
Iwordpress.inf o [10/16/2010] – The dental seo marketing provides highest returns on the investment. Most of the person search for good dentist through online. It the website is not appeared in the first page then it will not reach to a person. In this Dental SEO Marketing is they make sure that the potential clients searching for a web. Through that people can find their required information about the dentist. This searching is performed by the user on every day.
shinyshiny.tv [2011-01-10] – We all dread going to the dentist. The very sound of the drill is more than enough to leave even the toughest of us shaking in our shoes. That is why King’s College Dental Institute’s Professor Brian Millar has invented a noise cancellation device that eliminates the unnerving sound of dental drills.
Many people put off going to the dentist because of anxiety associated with the noise of the dentist’s drill. But this device has the potential to make fear of the drill a thing of the past.
The beauty of this gadget is that it would be fairly cost-effective for dentists to buy, and any patient with an MP3 player would be able to benefit from it, at no extra cost. read more …

A 3D scanner is a device that analyzes a real-world object or environment to collect data on its shape and possibly its appearance (i.e. color). The collected data can then be used to construct digital, three dimensional models useful for a wide variety of applications. These devices are used extensively by the entertainment industry in the production of movies and video games. Other common applications of this technology include industrial design, orthotics and prosthetics, reverse engineering and prototyping, quality control/inspection and documentation of cultural artifacts.
Many different technologies can be used to build these 3D scanning devices; each technology comes with its own limitations, advantages and costs. It should be remembered that many limitations in the kind of objects that can be digitized are still present: for example optical technologies encounter many difficulties with shiny, mirroring or transparent objects.
There are however methods for scanning shiny objects, such as covering them with a thin layer of white powder that will help more light photons to reflect back to the scanner. Laser scanners can send trillions of light photons toward an object and only receive a small percentage of those photons back via the optics that they use. The reflectivity of an object is based upon the object’s color or terrestrial albedo. A white surface will reflect lots of light and a black surface will reflect only a small amount of light. Transparent objects such as glass will only refract the light and give false three dimensional information [Wikipedia credit].
3D Scanning digital imaging and dentistry are merging into one technology innovation – A 3D Scanner for dentistry.
KaVo, based in Leutkirch, Germany, is pioneering digital production of dental devices that saves time by automating the process and eliminating the need for adjustment. The new manufacturing process also enables superior materials to be used that are difficult or impossible to incorporate into the traditional manual process.
KaVo has adopted many of the digital design technologies traditionally used by auto and aerospace industries. But, the need for individualized products provides a unique challenge for the dental industry. read more ...

Very good points have been published by Ken Serota on December 17, 2010 in the article “5 tips for marketing your dental practice”
Marketing a dental practice is simply not what it used to be. Years ago you could just take out an advertisement in the Yellow Pages or send direct mailers. In today’s saturated media market, these efforts often just end up in the recycling bin. While many dentists still swear by these methods, I argue that you’re not only missing the huge (and growing) group of patients who are online, but also that there is no way to track the success of your
DentistryIQ (2010-12-13) – Syneron Dental introduces Laser-in-Handpiece technology.
YOKNEAM, Israel–Syneron Dental, a provider of dental laser solutions, has announced a patented Litetouch System, featuring the company’s Laser-in-Handpiece technology, has been installed in numerous clinics and universities in 2010.
To read more about laser technology, go to laser technology.
The system provides dentists across Europe and the Far East with the ability to use lasers to perform complex dental procedures that had previously not been possible with traditional dental laser systems.
Syneron Dental’s LiteTouch is an all-tissue, nonfiber, nonarticulated arm Er: YAG dental laser for use on hard- and soft-tissue procedures. LiteTouch generates the laser’s energy within the handpiece, allowing for greater energy transfer than ever before. It provides dentists with high-speed cutting ability, power, precision, and maneuverability. read more …

Censorship in China
We know that the Government of People’s Republic of China worries about their people and as a result they censorship all their after activities. China is already blocking Plurk, Facebook, YouTube, Flickr, Blogspot, Hotmail, Wikipedia and Twitter.
According to Chinese government, in 2010 there were 60,000 websites shot down due to the pornographic and obscene content. I really can not believe there were so many pornographic website in China. In a statement on December 30,2010 Wang Chen, a head of the State Council Information Office, announced that there would be no stopping its campaign against material it deemed obscene.
On the positive site our blog is still open for people in China to read 🙂
