They looked like normal teeth, were sensitive to pain and chewed food easily.While the experiments were on mice, they pave the way for people to 'grow their own teeth' as required. The technique could also be adapted to other organs, allowing hearts, lungs and kidneys to be grown inside the body to replace parts worn by age or damaged by disease. The Japanese study focused on stem cells - 'master cells' with the ability to turn into other cell types.The researchers from the Tokyo University of Science identified two types of stem cell, which together contain all the instructions for a fully grown tooth. The cells were grown in the laboratory for five days until they formed a tiny tooth 'bud'. This was then transplanted deep into the jawbone of a mouse that had had a tooth removed. Five weeks later, the tip of the tooth broke through the gum. And after seven weeks, it was fully-grown, the journal Proceedings of the National Academy of Sciences reports. The researchers, who repeated the experiment many times, also showed that the new, bioengineered teeth were fully-functional.Dr Kazuhisa Nakao said: 'Every bio- engineered tooth erupted through the gum and had every tooth component such as dentine, enamel, pulp, blood vessels, nerve fibres, crown and root.'The new tooth at full size, seen at the back of the mouse's mouth (fluorescent protein causes it to glow green).Importantly, the rodent recipients had no trouble eating.The cells used were take from mouse embryos, but the researchers believe it should be possible to make teeth from other types of cell as well. They are now looking for suitable cells in people. Possibilities include skin cells and cells from the pulp inside teeth. They also have to work out how to control the size of the bio-engineered teeth, as those grown in the experiments were slightly smaller than usual. The process would also have to be speeded up if it was to be used on people as human teeth take years to form.However, the pioneering technology could one day allow those with teeth missing to fill the gaps in their smile without having to resort to false teeth, bridges or synthetic implants.Experts believe that using 'living' teeth rather than artificial ones would be better for oral health and may also provide a more natural 'bite'. Bio- engineered teeth are likely to cost around £2,000 each - a similar price to the implants used at the moment. But Britain's 11 million denture wearers should not throw away their fixative creams and gels quite yet. The technology is still at a very early stage and the Japanese researchers believe it will not be widely used by dentists for at least 15 years. Despite this, British experts said it was an important landmark.Professor Robin Lovell-Badge, a stem cell researcher at the National Institute for Medical Research in London, said the work was 'excellent' and highlighted the promise of using bio-engineering to make complex structures. But he cautioned that the researchers had yet to find cells suitable for use in people. Professor Damien Walmsley, of the British Dental Association, said: 'If you lose a tooth at the moment, one of the options is a metal implant. If you could have a natural replacement, that would be good.'Natural-looking replacements-also have massive psychologicalbenefits for self-conscious patients.The technique of creating cell 'buds' could be applied more widely to grow other organs, such as hearts, kidneys and livers, inside the body. Lead researcher Professor Takashi Tsuji said: 'The ultimate goal of regenerative therapy is to develop fully-functioning bioengineered organs that can replace lost or damaged organs following disease, injury or ageing.''Our study makes a substantial contribution to the development of bio- engineering technology for future organ replacement therapy.' JofER editor Mon, 10 Aug 2009 00:00:00 CDT http://endodonticsjournal.com/blogs/23/Natural-Tooth-Filling.html Researchers at Tufts University are working on a way to use stem cells to repair tooth decay. How it works: Tooth-growing cells are seeded into polymer scaffolds. The scaffolds are then implanted into the jaw, where they regenerate tooth enamel, dentin and pulp. The operation has been successfully tested in pigs and rats.Availability: Could be available for humans within seven years. JofER editor Wed, 08 Jul 2009 00:00:00 CDT http://endodonticsjournal.com/blogs/22/Dentistry-Of-Future.html A team of researchers lead by Professor Dr Thimios Mitsiadis at the University of Zurich, Switzerland, has identified a gene responsible for the formation of enamel, which is the key component of the teeth. The experiments were accomplished in mice carrying a deletion of the transcription factor Tbx1, a gene that plays a principal role in several human malformations (heart, thymus, parathyroid, face, and teeth) associated to the DiGeorge syndrome."Subjects afflicted by DiGeorge syndrome exhibit teeth with enamel defects. We have demonstrated that a direct link between impaired Tbx1 function and enamel defects exists. Enamel forms via the mineralization of specific enamel proteins that are secreted by dental epithelial cells called ameloblasts. Our results clearly show that teeth of Tbx1 null mice lacked enamel and ameloblasts," explains Prof Mitsiadis.These findings, just published in Development Biology, represent a major contribution to the understanding of the production of enamel, the "hardest organic tissue" found in nature. An American group of researchers from the University of Oregon have also shown a relationship between another transcription factor (Ctip2) and the production of enamel, but in the words of Prof Mitsiadis "our investigations better demonstrate the lack of enamel in teeth. Because of the early lethality of the Tbx1 mutant mice, we have used long-term culture techniques that allow the unharmed growth of teeth until their full maturity. No such studies were performed from our American colleagues." Could dental treatment benefit in the future from this revolutionary study? The answer is definitively "yes." "The understanding of the genetic code controlling tooth development and repair will permit us to imagine and generate new products and replacement tissues for injured and unhealthy teeth. However the requirements for functional tooth repair and/or formation are complex. Yet, a single approach has not allowed an effective clinical therapy," says Prof Mitsiadis.Is it possible to use dental stem cells to stimulate the growth of new enamel? This represents the biggest challenge in the discipline of tooth engineering. "Our results show that Tbx1 is involved in the maintenance of dental epithelial stem cells that are responsible for ameloblast formation. In some cases of genetic tooth anomalies, regeneration and repair of teeth could be treated by stem cells. Aggregates of dental stem cells could be used in the future for local transplantation in the dental tissues," explains Prof Mitsiadis.Table 1.

JofER editor Mon, 02 Mar 2009 00:00:00 CST http://endodonticsjournal.com/blogs/21/Man-pulls-out-13-of-his-own-teeth-with-pliers-because-he-couldnt-find-an-NHS-dentist.html A former soldier pulled his own teeth out with a pair of pliers because he could not find a dentist to take on NHS patients.Iraq War veteran Ian Boynton could not afford to go private for treatment so instead took the drastic action to remove 13 of his teeth that were giving him severe pain. The 42-year-old, from Beverley, East Yorkshire, had not had his teeth looked at since seeing the army dentist in 2003. He had not been registered with a dentist of his own since 2001.He said: 'I've tried to get in at 30 dentists over the last eight years but have never been able to find one to take on NHS patients.' But when Mr Boynton started suffering from toothache in 2006 he decided to take drastic action. He said: 'I started having pain in a front tooth, which protruded slightly more than the others. I was constantly fiddling with it and wiggling it because it hurt so much. 'In the end I knew it had to come out and had to use the pliers to pull it.  Amazingly, it did not hurt as much as you might think.'I think I'd been prising it that much in the meantime that I'd been killing the nerve.'In the last two years Mr Boynton has pulled out 13 top teeth including molars, incisors and canines. He now only has two teeth left in the roof of his mouth. He served as a medic in Iraq in 2003, but six months after leaving the Territorial Army had an accident while working as a paint sprayer that aggravated an old back injury. Unemployed Mr Boynton, who is single, said: 'It's a horrible situation to be in when you can't afford to go to the dentist when your teeth were so bad.' In a stroke of ill-timed luck he has now finally found a dentist to take him on.Mr Boynton said: 'I think the situation has improved slightly because of all the uproar. Unfortunately it came too late for me. 'I desperately needed a dentist because, although I'm no longer in pain, I need to have false teeth as I'm finding it difficult to eat.'Unfortunately I can't make false teeth myself.'A spokesman for NHS East Riding of Yorkshire said Mr Boynton's case gave an 'inaccurate scare-mongering picture of dental service provision in East Yorkshire based solely on the claims of one man'. The spokesman said: 'As well as 34 dental practices, we have seven dental access centres across East Riding of Yorkshire, including Beverley, where Mr Boynton could access a full range of NHS dentist services. 'So there is absolutely no reason why anyone should have to resort to pulling out their own teeth.  NHS East Riding of Yorkshire has invested around £1 million in helping dentists target new patients.  At many of our dental practices appointments are being offered to new patients within two weeks.'Our local out-of-hours and Accident and Emergency Services would have both been able to give Mr Boynton details of how to access emergency/urgent dental services if he had approached them.' JofER editor Fri, 13 Feb 2009 00:00:00 CST http://endodonticsjournal.com/blogs/20/Dentist-in-a-Supermarket.html The clinic will be open seven days a week and shoppers will be able to pop in for treatments while buying groceries from 8am to 8pm. It is offering check-ups by private dentists for £16 in what could become a clear challenge to the NHS.The venture comes amid a shortage of NHS dentists, which has already seen 35,000 patients driven to travel abroad for treatment to countries including Hungary, Poland and Croatia. It is the brainchild of celebrity dentist Lance Knight â€" whose patients include boxer Amir Khan and models Caprice and Danielle Lloyd â€" and replaces a dry cleaning shop at a large branch of Sainsbury’s in Sale, Greater Manchester.It follows the first in-store GP surgery, which opened at a nearby Sainsbury’s. Yesterday the first patient to be treated was social worker Mary Gilfoyle, 51.She said: “I thought it was brilliant. I have even had a white filling. “I am with an NHS dentist but that would have cost £55 â€" and they couldn’t see me for two days.”Model Alex Leigh, 29, had her teeth whitened.She said: “Anything that lets you kill two birds with one stone is brilliant when we all lead such busy lives.”Check-ups are 20p cheaper than the NHS. Fillings start at £30, while an NHS dentist would charge £45.50, regardless of the number of fillings. Having a tooth removed will cost from £40, a hygienist’s appointment is £30 and teeth whitening will set shoppers back £295. New statistics show that 27million people have been treated by NHS dentists since they negotiated a new contract two years ago, a drop of 1.1million. Dr Knight claims that in some areas half of the population are not registered with an NHS dentist because of chronic shortages. He said: “This isn’t some gimmick, it is about giving something back to the community and putting patients first.” If the pilot surgery succeeds, he would like to roll surgeries out across Britain.The Daily Express has reported how Hungarian dentists have toured the country, offering treatment from mobile surgeries in tents with charges 70 per cent cheaper than other private dentists.www.express.co.uk JofER editor Thu, 16 Oct 2008 00:00:00 CDT http://endodonticsjournal.com/blogs/19/Fictional-dentists.html Bernard from the TV series Lost.Matthew Brock from NewsRadio.
