Good news for all… Needly Free Dentistry

Scientists at the University of São Paolo have developed a new pain-free way of administering dental anesthetic. Say goodbye to those unfavourable needles. In their study, scientists applied a topical anesthetic to the mouth lining of a pig and stimulated it using a tiny electric current.  They found that this electric current caused the anesthetic to diffuse more effectively. This method, a process called iontophoresis may be a potential replacement of injectable anesthetics. At the moment, researchers are trying to create an iontopheretic device that can be properly used in the mouth. So now we all wait with bated breath.
