Looking Into The Portable X-Ray Future

I saw this unit but it does not have FDA approval and may never see the light of day in the US. It is a camera style portable Xray unit with a built in digital sensor. It was quite light but I was quite concerned that it may not have adequate shielding. This is why it is so light but we will see what the future brings.

200 Year Old Denture

From Ananova

18th Century smile
A 200-year-old pair of French false teeth have gone on display for the first time to mark World Smile Day.
The 18th century teeth, worn by the Archbishop of Narbonne who died in 1806, were found in his coffin after an archaeologists' dig in London.
They were digging at St Pancras graveyard ahead of building work on the Channel Tunnel's new rail terminus, reports The Times.
The porcelain dentures, which were still sitting in Arthur Richard Dillon's mouth, have gone on display at the British Museum.
It is thought he may have bought the dentures, which feature gold springs, from top Parisian dentist Nicholas De Chemant.
Dillon, who was ordained as Archbishop of Narbonne in 1763, escaped the guillotine during the French Revolution before fleeing to England in 1791.
Museum of London archaeologist Natasha Powers said: "These unique artefacts reflect a pivotal time in dental history with the adoption of new materials and methods of manufacture.
"They also represent a period of significant social and economic change for the upper echelons of French society."

Portable X-Ray

I have been looking at the Aribex Nomad which is a portable xray unit. Hopefully I will have a demo unit in my office next week and I can report back on it.

New Film Developer

Here is something else from the GNYDM. A company called EcoNet Global has a film developer that doesn't need a darkroom. You feed the film into the processor with the film sleeve on and it gets stripped off and processed. They have a new version which will digitally scan the film. The processor will attach to a computer via USB. So you get a conventional film and digital image from conventional film.

Smart drug bites into tooth decay

22 November 2006
From New Scientist Print Edition

Dentists could soon be out of a job - a "smart bomb" antimicrobial drug that kills the bacteria that live in plaque could stop tooth decay in its tracks.

Traditional antibiotics are too indiscriminate to be used against Streptococcus mutans because they also kill commensal or "friendly" bacteria, paving the way for other mouth infections. Now Wenyuan Shi of the University of California, Los Angeles, has created an antimicrobial that spares commensal bugs.

The Truth About Digital Prints and Megapixels

From David Pogues Blog

We blew up a photograph to 16 x 24 inches at a professional photo lab. One print had 13-megapixel resolution; one had 8; the third had 5. Same exact photo, down-rezzed twice, all three printed at the same poster size. I wanted to hang them all on a wall in Times Square and challenge passersby to see if they could tell the difference.

We ran the test for about 45 minutes. Dozens of people stopped to take the test; a little crowd gathered. About 95 percent of the volunteers gave up, announcing that there was no possible way to tell the difference, even when mashing their faces right up against the prints. A handful of them attempted guesses—but were wrong. Only one person correctly ranked the prints in megapixel order, although (a) she was a photography professor, and (b) I believe she just got lucky.

I’m telling you, there was NO DIFFERENCE.

Voice recognition improvements

Check out this You Tube Video

In October 2006, Nuance Communications hosted a challenge to determine the fastest and most accurate way to send text messages and email using mobile devices. In a classic match-up of man vs. machine, Ben Cook, recently crowned the world champion of text messaging, raced against Nuance Mobile Dictation, the speech recognition technology that allows mobile phone users to create text messages using speech.

Cook, a teen from Utah, holds the Guinness World Record for the fastest entry of a 160-character standardized message on a mobile device: “The razor toothed piranhas of the genera Serrasalmus and Pygocentrus are the most ferocious freshwater fish in the world. In reality they seldom attack a human.” Cook’s previous triple tap record for the standard message stood at 42.22 seconds.

Something New From PALM

Palm founder and CTO Jeff Hawkins reveals in an interview with the San Jose Business Journal that Palm has a third business (after PDAs and smartphones) that they haven't yet revealed to the public. He does mention that it has something to do with mobile computing.

For those who don't know Jeff Hawkins is the inventor of both the Palm Pilot and Treo smartphone.


I’ll give you a couple clues. I always think of mobile computing as personal computing. This long-term vision has led us through everything — first the organizers and now through the smart phone space. It’s like everything a personal computer is. Continue down that path. What are the implications of a world where everyone has a super high-speed Internet connection in their pocket and many gigabytes of storage, super-fast processors, audio, visual and multimedia? What are the consequences of that? How will that change computing when you have all that stuff available to you all the time? I try to think into the future. That’s how we come up with new products. So I’m not going to tell you what it is, but it’s following the consequences of mobile computing.

iPhone is coming

The Chinese-language newspaper Commercial Times is reporting that Hon Hai Precision Industry Co Ltd. is producing an phone that also has the same multimedia functionality as an iPod.

Reportedly, Apple has ordered 12 million of these for delivery some time before the middle of next year.

Many are expecting this device, often referred to as the iPhone, to be announced at the MacWorld Expo in January

Microsoft is planning their own music player phone.

I am not sure whether these phones will be smartphones or just be able to play tunes.

Injection Speed Influences Efficacy

From October 2006 Journal of Endodontics

Speed of Injection Influences Efficacy of Inferior Alveolar Nerve Blocks: A Double-Blind Randomized Controlled Trial in Volunteers
Mohammad Dib Kanaa, MPhil, DDS, John Gerard Meechan, PhD, BDS, Ian Porter Corbett, PhD, BDS, John Martin Whitworth, PhD, BChD

This randomized double-blind crossover trial investigated the efficacy and discomfort associated with slow (60 seconds) and rapid (15 seconds) inferior alveolar nerve blocks (IANB) using 2.0 ml of 2% lidocaine with 1:80,000 epinephrine in securing mandibular first molar, premolar and lateral incisor pulp anesthesia in 38 healthy adult volunteers. Episodes of maximal stimulation (80 μA) without sensation on electronic pulp testing were recorded. Injection discomfort was self-recorded by volunteers on 100 mm visual analogue scales. Data were analyzed by McNemar, Friedman, Wilcoxon Signed Ranks, and paired t tests. Slow IANB produced more episodes of no response to maximal pulp stimulation than rapid IANB in molars (220 episodes versus 159, p < 0.001), premolars (253 episodes versus 216, p = 0.003) and lateral incisors (119 episodes versus 99, p = 0.049). Slow IANB was more comfortable than rapid IANB (p = 0.021).

Speed Up Your Internet Connection

OpenDNS provides a safer, faster, more reliable and smarter DNS service free to any Internet user.

Two things make OpenDNS faster than similar services. First, OpenDNS runs a really big, smart cache, so every OpenDNS user benefits from the activities of the broader OpenDNS user base. Second, OpenDNS runs a high-performance network which is geographically distributed and serviced by several redundant connections. OpenDNS responds to your query from the nearest location. That means we're very fast (and extremely reliable, to boot).

It even corrects typos in a URL that you type. I have tried this service and it works as advertised. So even if you don't understand the terminology go check out the web site and try it for yourself.

Perio Disease and Preterm Births

From the New England Journal of Medicine

Treatment of Periodontal Disease and the Risk of Preterm Birth

Bryan S. Michalowicz, D.D.S ., James S. Hodges, Ph.D., Anthony J. DiAngelis, D.M.D., M.P.H., Virginia R. Lupo, M.D., M.P.H., M. John Novak, B.D.S., Ph.D., James E. Ferguson, M.D., William Buchanan, D.M.D., M.Md.Sc., James Bofill, M.D., Panos N. Papapanou, D.D.S., Ph.D., Dennis A. Mitchell, D.D.S., M.P.H., Stephen Matseoane, M.D., Pat A. Tschida, Ph.D., for the OPT Study

Background Maternal periodontal disease has been associated with an increased risk of preterm birth and low birth weight. We studied the effect of nonsurgical periodontal treatment on preterm birth.
Methods We randomly assigned women between 13 and 17 weeks of gestation to undergo scaling and root planing either before 21 weeks (413 patients in the treatment group) or after delivery (410 patients in the control group). Patients in the treatment group also underwent monthly tooth polishing and received instruction in oral hygiene. The gestational age at the end of pregnancy was the prespecified primary outcome. Secondary outcomes were birth weight and the proportion of infants who were small for gestational age.
Results In the follow-up analysis, preterm birth (before 37 weeks of gestation) occurred in 49 of 407 women (12.0%) in the treatment group (resulting in 44 live births) and in 52 of 405 women ( 12.8%) in the control group (resulting in 38 live births). Although periodontal treatment improved periodontitis measures (P<0.001), it did not significantly alter the risk of preterm delivery (P=0.70; hazard ratio for treatment group vs. control group, 0.93; 95% confidence interval [CI], 0.63 to 1.37). There were no significant differences between the treatment and control groups in birth weight (3239 g vs. 3258 g, P=0.64) or in the rate of delivery of infants that were small for gestational age ( 12.7% vs. 12.3%; odds ratio, 1.04; 95% CI, 0.68 to 1.58). There were 5 spontaneous abortions or stillbirths in the treatment group, as compared with 14 in the control group (P=0.08).
Conclusions Treatment of periodontitis in pregnant women improves periodontal disease and is safe but does not significantly alter rates of preterm birth, low birth weight, or fetal growth restriction. ( number, NCT00066131 [] .)
