Disinfection/sterilization of dental instruments and endoscopes

  • The Surface Micro Discharge (SMD) technology facilitates the development of scalable and flexible plasma electrodes.
  • In a feasibility study for disinfection/sterilisation of dental instruments we developed a functional model consisting of several cylindrical SMD electrodes.
  • By pumping the air and plasma species produced by the electrode through the fine channels and cavities of the instruments, these could be disinfected, respectively sterilised.
  • The validation of this method was confirmed by certified, external service providers. The results showed a reduction of Enterococcus faecium to 99.9999% in the fine channels and cavities of different dental instruments.

Sterilisation of thermolabile equipment

  • Based on the Surface Micro Discharge technology large and also encapsulated plasma electrodes can be developed.
  • terraplasma GmbH designed a functional prototype to demonstrate that sterilisation – i.e. a reduction of e.g. Geobacillus stearothermophilus to 99.9999% - is feasible even within a short treatment period of less than 5 min.
  • Studies regarding the scalability demonstrate that the development of big chambers with large electrodes for sterilizing larger thermolabile equipment is feasible.
