Cold atmospheric plasma – clinical application in dentistry

Cold atmospheric plasma is defined as partially ionized gas composed of various components such as electrons, positive and negative ions, free radicals, photons, ultraviolet and infrared radiation, atoms and molecules with the lack of thermal equilibrium between the electrons and the other components of the plasma. The basis of plasma may consist of various kinds of gases (ambient air, noble gas or a mixture of noble gases). Cold atmospheric plasma field can be produced by various plasma generators. A high-frequency generator Ozonyx (Biozonix, Munich, Germany) produces high-frequency electric field (resonant frequency 30–50 kHz, pulse frequency 470–1050 Hz, trigger 3–18 kV voltage, current 100 μA). Cold atmospheric plasma field may be used as an effective method for the various non-invasive therapeutic procedures in dentistry, as a primary therapy or as a support for other types of therapy.
