Had decreased the concentration of the least harmful microorganisms in experiments on infected, previously pulled teeth by a factor of 10,000, said the scientists of the Leibniz Institute for Surface Modification in Leipzig and the University Hospital of the Saarland.

In the novel treatment helium is passed through a narrow nozzle and excited by microwaves. In this way, the noble gas reaches the fourth state (down to) liquid and gas and is plasma forming.

The fine resulting beam reach temperatures between 30 and 40 degrees Celsius. “This makes the temperature compatible” said Stefan dentists Rupf to the German news magazine Der Spielgel. Excessively high temperatures could damage the nerves that would be avoided in this way.

The researchers believe their technology could be designed with the treatment of dental caries gently and effectively. Previously, tests on patients are still necessary, the market maturity of the procedure would be to probably reached only in a few years.
