Titolo: Riparazione denti naturale, che ne pensate?

Un gruppo di scienziati ha creato un nuovo apparecchio che aiuta a far
ricrescere i propri denti.
Questa piccola macchina ad ultrasuoni può essere agevolmente posta
all'interno della cavità orale e sostanzialmente massaggia, in modo
continuativo, le gengive del paziente, stimolando lo sviluppo dentale
della radice.
É totalmente sprovvisto di fili ed è comandato da un altrettanto
piccolo telecomando esterno, gestito direttamente dall'utente.
Il team dell'Università di Alberta, in Canada, spera di riuscire ad
arrivare alla sua commercializzazione in non più di due anni, visti i
rilevanti successi ottenuti in fase di sperimentazione.
Questo device, chiamato LIPUS (low-intensity pulsed ultrasound
system), è stato concepito per intervenire li dove sono avvenute
fratture dell'osso corticale e/o trabecolare, e in futuro diventerà
certamente utile per tutti coloro che amano gli sport che possono
mettere a rischio la propria arcata dentale (come la boxe).
Il sistema attualmente necessita di essere attivato per 20 minuti al
giorno, per almeno quattro settimane; solo dopo questo intervallo di
tempo inizieranno ad essere visibili i primi risultati.

Broke a tooth? Grow it back ...
Waves beamed from dental ultrasound device developed at U of A have
healing power

EDMONTON - Long used as a test for pregnant women, ultrasound may soon
have a new role -- growing teeth.
A team of University of Alberta researchers is seeking a U.S. patent
on a tiny device that will sit inside the mouth and beam ultrasound
waves at teeth.
The device won't help Ryan Smyth, the Edmonton Oiler who lost three
teeth in the hockey playoffs, but it may prevent tooth damage that can
occur from wearing braces.

Font: ****And it may do much more than that. The research team
envisages bandages embedded with tiny ultrasound machines that may
some day be wrapped around broken legs to help the bone heal more
quickly.
The idea originated with Dr. Tarek El-Bialy, an Egyptian-born
orthodontist who joined the university's faculty of dentistry a year
ago.
El-Bialy has shown in earlier research that ultrasound waves, the high
frequency sound waves normally used for diagnostic imaging, help bones
heal and tooth material grow.
"I was using ultrasound to stimulate bone formation after lower-jaw
lengthening in rabbits," El-Bialy said in an interview Tuesday.
To his surprise, not only did he help heal the rabbits' jaws after the
surgery, but their teeth started to grow as well.
He later did a human study to see if ultrasound could prevent damage
to the roots of teeth when people wear braces. Braces force the teeth
to move, and that can cause root damage.
That study, published in 2004, showed that a tooth getting a daily
shot of ultrasound was protected from damage, and in fact had more
dental tissue than before.
"The problem was that the ultrasound device we were using was very
big, and the patient had to hold it in his mouth for 20 minutes every
day," El-Bialy said.
When he moved to the U of A, he joined forces with two members of the
engineering faculty, Jie Chen and Ying Tsui, to design an ultrasound
machine small enough to sit inside a person's mouth. Chen is an expert
in small-circuit devices, Tsui in ultrasound. They think it will take
a year to create a workable ultrasound device less than a centimetre
long, small enough to attach to braces or to a plastic temporary crown
and powered by a tiny battery.
Tsui said once the device -- which has been named LIPUS, for low-
intensity pulsed ultrasound -- is created, it can be used for a
variety of purposes. One idea is to make bandages embedded with tiny
ultrasound devices, for healing broken bones.
Ultrasound has also been shown to stimulate the growth of stem cells,
the cells that create all other cells, he said. An ultrasound device
could be made for triggering stem cell reproduction.
El-Bialy also has work to do. So far, he has been able to stimulate
growth of the inner part of teeth, but not the enamel. That's why he
can't regrow Ryan Smyth's teeth.
He's starting new research to try to use ultrasound to repair cracked
or broken teeth.
The researchers estimate their LIPUS device will be ready for public
use within two years.

or broken teeth.
Posso farti presente che lo studio di cui si parla nell'articolo, non
citato ma vabbè, dimostra solo che una quotidiana pulizia con gli
ultrasuoni (quelli che usano i dentisti per fare la pulizia, guarda
caso) protegge i denti dal danno, e che di ricrescita documentata dei
denti in seguito ad ultrasuoni nell'articolo stesso non c'è traccia?
