False teeth could soon be a thing of the past after scientists discovered a way to grow them in a lab after splitting the cells that develop into pearly whites.

Dental experts have found a new way to split a tooth into two fully functional teeth and then successfully implant them into the jaws of mice – a breakthrough which could help human patients in the future.

Researchers from the RIKEN Centre for Developmental Biology in Japan used a new technique of extracting teeth germs – the groups of cells formed early in life that will later develop into teeth.

The scientists said they managed to split the germs in two and then implant the new teeth to the mice’s jaws.

The study, published in Scientific Reports of the journal Nature, shows current treatments fail to restore the full functionality of a tooth, which makes naturally growing new teeth far more beneficial.

Other experts consider teeth a major target for regenerative medicine, as about 10 per cent of people are born with some missing teeth and many people lose teeth due to accidents or disease as they age.

The researchers set about trying to make new teeth from a single germ.

Teeth germs were removed from mice and were sliced into two with nylon thread.

The experiment took about 15 days to develop the germ naturally into two teeth.

The study shows the new teeth allowed the mice to chew and feel stimulus. However, the implanted teeth were just half the size of normal teeth.

Lead researcher Takashi Tsuji said the new method could be especially useful for children who so not have properly developed teeth due to conditions like cleft lip or Down syndrome.

Germs of permanent teeth or wisdom teeth could be used to develop new fully functional teeth that can be implanted.

Dr Tsuji added that they could soon consider using stem cells to grow more germs, but further tests are needed for the process.


New ‘selfie’ pose mimicking toothache takes off


There have been numerous different poses that have gone in and out of fashion over the years, and with the ever increasing popularity of online social media, it looks like the ‘selfie’ is set to evolve much more in the future – if current trends are anything to go by. The newest form of selfie – a photograph taken by the subject of the picture – is known as the ‘cavity pose.’

As ridiculous as it may sound, the latest selfie trend is for subjects to pose like they have toothache, with one hand up against the cheek as though they are in pain. Japan has been the origin of many strange online trends and this is their newest wacky idea that is set to sweep the internet – according to website Kotaku, the first to notice the selfie pose catching on. The site explains that ‘the gesture makes one’s face appear smaller, and small faces are considered attractive in Japan.

The pose has now been spotted on the front of six Japanese fashion magazines and a picture showing the covers has been retweeted over 35,000 times. It seems the craze may be catching on too, as more and more Twitter and Instagram users are joining in, posting their own ‘cavity pose’ pictures online.

Japanese researchers believe that dental fear may be triggered by sound


New research from Japan has revealed that dental phobia may be triggered by the sound of dental drills and suction instruments used during surgery. Researchers at the Nippon Dental University in Tokyo carried out brain scans on volunteers whilst the sounds of dental instruments were being played; people who were scared of the dentist showed a noticeable difference in brain response compared to those that were not worried about undergoing dental treatment. The results were reported at the Society for Neuroscience meeting in San Diego on Sunday.

Dentist Hiroyuki Karibe, a researcher at the University, asked 21 women and 13 men aged between 19 and 49 to complete a survey with questions like ‘do you get tense during dental treatment?’ and ‘do you feel anxious when you hear the dental drill?’ Volunteers answered on a scale of one to five, with one being ‘not at all’ and five representing ‘very much’.

The volunteers were then divided into high-fear or low-fear groups according to their scores, and Karibe scanned their brains using a functional magnetic resonance imaging machine (fMRI) whilst playing a serious of sounds associated with dental treatment.  Each participant registered some brain activity in response to the sounds; those with a high-fear of the dentist presented a more intense response in the left-hand region of the brain, known as the caudate nucleus, which plays a role in learning and remembering sounds.

Karibe told The Guardian that ‘We believe the findings can be applied to assess the effectiveness of interventions such as cognitive behaviour therapy for patients who have a strong fear of dental treatment.’

Scientists discover that diamonds could improve implant durability


New research has revealed that tiny spherical diamonds could be helpful when trying to encourage bone growth and improve the performance of dental implants. The gems are so small they cannot be seen by the human eye and they could be used to combat forms of bone loss including osteonecrosis, a disease where the bones break down due to reduced blood flow.

Scientists from UCLA and the NanoCarbon Research Institute in Japan discovered that the nanodiamonds could deliver proteins to the teeth to treat the symptoms of osteonecrosis, making implants more stable and functional by maintaining the bone around the sockets.

Dean Ho, professor of oral biology and medicine at the UCLA School of Dentistry, led the study and it was later published in the Journal of Dental Research. He explained that previous methods of bone restoration involved placing a sponge surgically into the tissue to administer proteins that promote bone growth. Dr Ho’s team discovered that nanodiamonds could deliver the same proteins more efficiently because they bind with the bone, allowing the affected area to be treated for a longer period of time. The diamonds can also be administered without the need for surgical treatment, either by an injection or an oral rinse.

Dr Ho added that ‘Because they are useful for delivering such a broad range of therapies, nanodiamonds have the potential to impact several other facets of oral, maxillofacial and orthopedic surgery, as well as regenerative medicine.’

Elderly people ‘may need help with emergency dentistry prevention’


Older people could need help if they are to avoid emergency dentistry.People who have elderly relatives have been encouraged to help them when it comes to emergency dentistry prevention.

Writing for the Windsor Star, Dr David Mady said "it is imperative that the elderly receive good oral healthcare on a regular basis", or they may develop problems such as decay.

Writing in response to a query from a reader whose mother is suffering from dementia, the expert recommended helping her to brush and floss her teeth.

He said it is best to use a soft-bristled brush and non-flouride toothpaste similar to that available for children if she tends to swallow it.

Dr Mady also stressed the importance of flossing, explaining that bleeding gums and possible infection could be the result if this is not done regularly.

He said automatic flossing tools are available for people who may be having problems with traditional floss.

Earlier this month, a study carried out in Japan and published in the journal Behavioral and Brain Functions found that elderly people who have to have dental implants because all of their teeth have fallen out may also be more susceptible to dementia.

Could dental fad become as popular as teeth whitening?


Would you prefer teeth whitening or neon gnashers?A fad from Japan could become the partygoers' equivalent to teeth whitening if it catches on in the UK and US.

Inventors created LED fronts a little like mouthguards as an experiment, but they were snapped up by a Japanese retailer to publicise a winter sale.

The products are fitted on to the teeth and light up in different colours when the wearer smiles.

They caught on with teenagers and young adults and are now being sported all over the country, with the manufacturers describing them as a "party in your mouth".

It is possible they could pop up in schoolyards in this country, presenting an alternative to teeth whitening for extroverts, but traditional cosmetic dentistry is likely to remain more popular in the long term.

This is not the first time a tooth-related trend has hit the headlines – cosmetic dentistry practitioners recently criticised Kanye West for having all his bottom teeth at the front replaced with diamonds.

Yoghurt ‘can cause tooth decay’


Yoghurt 'can cause tooth decay'Children who consume large amounts of yoghurt containing sugar could require emergency dentistry to repair rotten teeth, a dentist has warned.

Dr Nigel Carter, chief executive of the British Dental Health Foundation, said: “It should be remembered that many yoghurts in the UK contain added sugar and … that increasing the frequency of sugar containing foods and drinks leads to an increase in dental decay”, the Daily Mail reports.

The dentist’s comments came in response to a study into tooth decay in children by researchers at Fukuoka University in Japan.

Of 2,058 Japanese children aged three-years-old it was found that there was less decay among those who ate yoghurt on a regular basis.

Factors such as diet history, tooth-brushing frequency, if the child snacked, used fluoride or was exposed to smoking while in the womb were all taken into account, alongside the parents’ level of education, when compiling the results.

The importance of children brushing their teeth twice a day was recently reported by My Joy Online, which explained that children’s teeth enamel is not as dense as adults.ADNFCR-2621-ID-19818263-ADNFCR

Green tea ‘could boost oral health’


Brits could improve their oral health through drinking green tea.

Research carried out in Japan by Yasushi Koyama from Tohoku University Graduate School of Medicine has shown a link between drinking green tea and improved oral health.

The report showed a 23 per cent reduction in the risk of decay in those people who drank a cup of green tea every day in comparison to those that did not.

It concluded that catechins found in the tea help prevent the build-up of bacteria that are linked to the risk of periodontal disease and decay and as such, regularly drinking the beverage can help improve overall dental health.

Elsewhere, C Health recently reported many people falsely assume that stained teeth come about as a result of poor oral health and this is not always the case.

Indeed, the other factors which can increase the likelihood of stains include smoking, bad diets, drinking large amounts of coffee or red wine.

Japanese dental students ‘practice on robot’


Students in Japan are practicing dentistry on a robot.

Dentistry students In Japan are now able to practice their skills on a robot, ahead of actually treating human patients, it has been revealed.

According to News Centre, 88 students at Japan’s Showa University have been able to carry out treatments on a robot that mimics the human mouth. It enables the students to hone their skills safe in the knowledge that they cannot cause any harm.

“Medical skill and ability is first built upon failures. One’s skills only improve once they have failed once,” said vice-director of Showa University Dental Hospital Koutaro Maki.

As a result, the institute has developed a robotic surrogate on which students can practice their skills without harming anyone in the process.

Elsewhere, Dr James McAnally, director of the Healthy Heart Dental Program, recently revealed that having good oral health is key in the fight against gum disease.

He noted taking the time to get regular check-ups from the dentist could dramatically improve a person’s health and increase their lifespan in the process.

Dried fruits ‘don’t damage teeth’


damaged teethDried fruits in cereal do not damage teeth.

Brits worried about damaging their teeth and the possibility of trip to the emergency dentist because of dried fruit in their cereal have been told to relax.

Professor Christine Wu, who headed a team of scientists from the University of Illinois, carried out a study to reveal whether sticky fruits such as raisins in cereal increased the risk of a person developing cavities.

She commented: “Studies have shown that raisins are rapidly cleared from the surface of the teeth just like apples, bananas and chocolate.”

As a result, no increased effect of decay was recorded, meaning the chances of this old wives’ tale being true are remote.

Elsewhere, recently reported researchers at Kyushu University in Japan have found eating yoghurt could be beneficial to the gums.

A study by the research team concluded foods which contain high levels of lactic acid could be beneficial in tackling gum disease.
