A new Canadian tool can re-grow teeth say inventors

-----------------------------------

Snaggle-toothed hockey players and sugar lovers may soon rejoice as Canadian scientists said they have created the first device able to re-grow teeth and bones.<b style="color:#FFA34F"></b> <b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
The researchers at the University of Alberta in Edmonton filed patents earlier this month in the United States for the tool based on low-intensity pulsed ultrasound technology after testing it on a dozen dental patients in Canada.<b style="color:#FFA34F"></b> <b style="color:#FFA34F"></b>

<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>"Right now,<b style="color:#FFA34F"></b> we plan to use it to fix fractured or diseased teeth,<b style="color:#FFA34F"></b> as well as asymmetric jawbones,<b style="color:#FFA34F"></b> but it may also help hockey players or children who had their tooth knocked out,<b style="color:#FFA34F"></b>"<b style="color:#FFA34F"></b> Jie Chen,<b style="color:#FFA34F"></b> an engineering professor and nano-circuit design expert,<b style="color:#FFA34F"></b> told AFP.<b style="color:#FFA34F"></b> <b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
Chen helped create the tiny ultrasound machine that gently massages gums and stimulates tooth growth from the root once inserted into a person's mouth,<b style="color:#FFA34F"></b> mounted on braces or a removable plastic crown.<b style="color:#FFA34F"></b> <b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
<b style="color:#FFA34F"></b>
The wireless device,<b style="color:#FFA34F"></b> smaller than a pea,<b style="color:#FFA34F"></b> must be activated for 20 minutes each day for four months to stimulate growth,<b style="color:#FFA34F"></b> he said.<b style="color:#FFA34F"></b>
