Robots have learned to brush their teeth from plaque

Dentists recommend at least a couple of times a year.Undergoing oral hygiene is a rather unpleasant procedure, during which teeth are cleaned of plaque and stones. No matter how terrible it may sound, in the future robots can do this, but it’s not worth being afraid - in fact, patients will just need to fill their mouths with liquid and sit under a magnetic field. The technology was invented by researchers from the School of Dental Medicine at the University of Pennsylvania, and it has already proven its effectiveness, and not only in dentistry.

The idea of ​​creating such a technology has come ratherunexpectedly: two groups of scientists have learned that they are working on different projects that can be combined into one and create something extremely useful for humanity. The first group was creating tiny robots of iron oxide nanoparticles that can be controlled with magnets. At the same time, another group found that the same iron oxide, when interacting with hydrogen peroxide, perfectly kills bacteria and destroys plaque.

By combining two ideas, scientists created the so-calledcatalytic antimicrobial robots, which are controlled by magnets and perfectly clean the teeth from plaque. Their tiny size and swimming in liquids allowed them to penetrate even the most inaccessible places and destroy the building materials that form the plaque. It is assumed that after such a cleaning, patients will be able to undergo hygiene much less frequently, because the plaque will form much longer.

Essentially, plaque is a biofilm thatconsists of a set of microorganisms that are closely interconnected and firmly adhered to the surface. Such a film can be formed not only on the teeth, but also on the medical equipment, and even more so inside the water pipes. Therefore, the technology has potential benefits not only for dentistry, but also for other areas.

It is much better than other methods of extermination.biofilms, because the current methods are not able to simultaneously destroy the protective layer, destroy bacteria and physically remove decaying residues. Iron oxide robots, in turn, do an excellent job with all this.

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