Ozone is present in the environment as a protective gaseous layer. It prevents living beings from the harmful effects of the high energy ultraviolet radiations. It was discovered in 1839 by Christian Friedrich Schonbein when he noticed the emergence of a pungent gas with an electric smell. The word ozone is derived from Greek word ozein that means odor. Since then it has been the field of research and clinical application in medicine and dentistry. The first medical application of ozone was traced back to 1870 by Dr. C. Lender, who used it for purifying blood in test tubes.
Ozone is a triatomic gaseous molecule, consisting of three oxygen atoms, showed its efficacy in the management of various pathologies in the field of medicine and dentistry. Ozone, which is used for medical purposes, is a gas mixture comprised of 95–99.95% oxygen and 0.05–5% pure ozone. Due to proven therapeutic advantages of ozone, many fields in dentistry could benefit from ozone therapy.
Although ozone is not a radical molecule, it is the third most potent oxidant (E_5 12.076 V) after fluorine and persulfate. Ozone is an unstable gas that cannot be stored and should be used at once because it has a half-life of 40 min at 20°C. Ozone is naturally produced by the photodissociation of molecular oxygen into activated oxygen atoms, which then react with further oxygen molecules. This transient radical anion rapidly becomes protonated, generating hydrogen trioxide, which, in turn, decomposes to an, even more, powerful oxidant, the hydroxyl radical. It is the fundamental form of oxygen that occurs naturally as a result of ultraviolet energy or lightning, causing a temporary recombination of oxygen atoms into groups of three.
Synthetic ozone can be produced by 3 different systems:
Ultraviolet system produces in low concentrations of ozone used in esthetics, saunas, air purification
Cold plasma system used in air and water purification
Corona discharge system produces a high concentration of ozone.
That in a nut shell is what we make and suspend in oil!
