New Teeth by Ultrasounds Therapy

Tweet

A team at University of Alberta has achieved for the first time through innovatory technology using low-intensity pulsed ultrasound (LIPUS) the regrowth of human dental tissue and teeth. The system-on-a-chip minidevice offers a non-invasive method to recover jaw and dental tissue. "It's very exciting because we have shown the results and actually have something you can touch and feel that will impact the health of people throughout the world," said Dr. Jie Chen, from the Department of Electrical and Computer Engineering and the National Institute for Nanotechnology. The wireless ultrasound minidevice would fit comfortably inside a patient's mouth wrapped in biocompatible materials. The unit will be easily mounted on an orthodontic bracket or a plastic removable crown. An energy sensor will ensure that the ultrasounds hit the target area of the teeth roots within the bone. The minidevice may be ready by the next year. "If the root is broken, it can now be fixed," said Dr. Tarak El-Bialy from the Faculty of Medicine and Dentistry. "And because we can regrow the teeth root, a patient could have his own tooth rather than foreign objects in his mouth." source: news.softpedia.com
