Robots to clean the teeth from plaque

Dentists recommend at least a couple times a year to pass the oral hygiene is a rather unpleasant procedure during which the teeth are cleansed of plaque and stones. It is as though terrible it may sound, in the future this business can do robots, but fear is not worth anything — in fact, patients will need just to fill your mouth with liquid and sit under a magnetic field. Technology invented by the researchers from the School of dental medicine, University of Pennsylvania, and she has already proved its effectiveness, not only in dentistry.

The idea of this technology came quite unexpectedly: the two groups of scientists found out that work on different projects that can be combined into one, and create something very useful for humanity. The first group engaged in the creation of tiny robots of nanoparticles of iron oxide that can be controlled by means of magnets. At the same time, another group found that the same iron oxide in the interaction with hydrogen peroxide great kills bacteria and destroys plaque.

Combining the two ideas, the researchers created a so-called catalytic antimicrobial robots that are controlled with magnets and clean the teeth from plaque. Their tiny size and swimming in the liquid allowed them to penetrate even into the most inaccessible places and destroy building materials, forming plaque. It is assumed that after such a treatment, patients are much less likely to pass the hygiene, because plaque will form much longer.

In fact, dental plaque is a biofilm that consists of many microorganisms that are closely related to each other and tightly coupled to the surface. Such film can be formed not only on teeth but also on medical equipment, and especially inside water pipes. Therefore, the technology poses potential benefits not only for stomatology, but also for other areas.

It is much better than other methods of extermination of biofilms, as the current methods are not capable of simultaneously destroy the protective layer to destroy bacteria and physically remove the decaying remains. Robots from the iron oxide in turn do an excellent job with all of this.

Perhaps in the near future dentistry will make a strong leap forward. Scientists are also developing a new type of dental filling with a life span of more than 7-10 years. Read more about them in our article.
