All things are poison and nothing without poison; only the dosage makes that a thing is no poison.
(Paracelsus 1493 to 1541)

In order to cleave the oxygen in a medically effective ozone an electric current not greater than a few microamperes is needed. This causes the irritation of the dental nerve when using the electrodes made of glas, also called probes. The Ozonytron devices of MIO turn on the power softly and thus avoid toothache. Due to the flowing micro current the cardiac pacemaker needs to be mentioned as contraindication. Other impairment can only result from the ozone exposition.

The production rate of ozone by the Ozonytron lies in the area of 0.002 to 2.9 microgram per second resulting in a concentration between 1 and 300,000 ppm. In the oral cavity, concentrations up to 13 ppm are produced by the open system. While performing the treatment, a partial ozone concentration up to 0.225 ppm is inhaled with the first breath of air.

When assuming that 0.5 litre of the compartment air is inhaled with an average breath of air and 70 % of the inhaled air reach the alveoli of the lungs which have an average capacity of 3.5 litre, the ozone is reduced to one-tenth resulting in an effective portion of ozone with an concentration of 0.0225 ppm. At the work area, ozone is allowed in a concentration of 0.1 ppm (18 % of the MAC (maximum allowable concentration)) which means that ozone with 0.0225 ppm doesn't pose a threat for the human health.

Although the portion of remaining ozone is small, we recommend the use of a proper suction device (e.g. aspirator of the dental treatment chair) during the treatment session in the oral cavity in a way that prevents the inhalation of the volatile ozone as far as possible. This applies especially to treatment session of more than 30 seconds.
