Plasmatron, capable to destroy the bacteria causing caries, can become effective and less painful alternative to a usual stomatologic drill.

It was revealed, that at a direction of a plasma beam on a dentine (the firm tissue of a tooth located under an enamel) quantity of tooth bacteria decreases in ten thousand times. This opening means, that in a pulp cavity it is possible to apply plasma technologies to the amazed tissues, usually for this purpose it is necessary to bore through a tooth.

Scientists from Leibniz-Institute of Surface Modifications, and stomatologists from Saarland University, have tested efficiency of plasma against usual oral pathogen, including Streptococcus mutans and Lactobacillus casei. These bacteria form Membranula on a surface of a teeth and can fret an adamantine substance of tooth and a dentine that leads to caries occurrence. If not to treat, it can lead to a pain, tooth loss, and sometimes and to serious infections of gums. In a course research scientists infected a dentine of a human molar with four kinds of bacteria and subjected to their influence of plasma in a current 6, 12 and 18 seconds. The more longly the dentine was under the influence of plasma, the remains the survived bacteria less.

About plasma speak, as about the fourth condition of substance after firm, liquid and gaseous. The number of technical and medical applications of plasma grows. Plasma can be found in space everywhere, it is formed, when high-energy processes ionise atoms of one or more electrons. So high-temperature active forms of oxygen which are capable to blast microbes turn out. Already today hot plasma is used for disinfection of surgical instruments.
Doctor Stefan Rupf from Saarlandsky university which took part in the given research, has declared, that recent working out of cold plasma in temperature about 40 degrees of Celsius has given the big hopes for stomatology. "The low temperature means, that plasma can kill microbes, thus keeping a tooth. The pulp in the tooth centre, being under a dentine, is bound to a vascular network and nerves, therefore it in no event cannot be subjected to heats".
Doctor Rupf says, that to occurrence of plasma technology for disinfection of tooth cavities will be glad both patients, and doctors. "Drilling - not so pleasant process, and sometimes and painful. Cold plasma, on the contrary, absolutely non-contact method and thus very effective. Now in the field of plasma medicine will reach huge progress, and in 3-5 years clinical treatment of tooth cavities by plasma becomes a reality".
