The formation of biofilm within the water circuits of dental chairs has its origin in the double possibility of contamination.
Firstly, from the water in the public water network, and secondly due to contamination from the patient's mouth.
Among the many infectious pathogens, both viral and bacterial, found in the water networks of dental studies, some are very dangerous: legionella, pseudomonas, tuberculosis bacteria, AIDS virus, and hepatitis C.
Water thus contaminated and containing bacterial load thousands of times higher than the limits established for drinking water, invalidates even the best practices for sterilization of the turbine and instrumentation in general, because after the cycle in the autoclave they are connected to the circuit of contaminated water.
This data is verifiable through a simple bacteriological analysis of the water.
It is necessary to consider the fact that, through the instruments of the dental chairs, the viruses and bacteria present in the water pipes are atomized into the environment in the form of aerosols and come into direct contact with the wounds of the subject patient. Therefore, the risk of cross infection between the dentist, patient and assistants is very high and therefore it must be counteracted by appropriate systems.
The recent interest in Legionella Pneumophila disease has to reflect on other much more dangerous diseases and therefore focus on the adoption of systems that prevent the production of biofilm and that effectively combat the proliferation of bacteria.
It is a centralized equipment that filters the water with the reverse osmosis process, eliminating the risk of contamination at the entrance to the water network and disinfecting it with stabilized Chlorine Dioxide (BIOXTERIL), eliminating the risk of contamination of the same for the reflux of viruses and bacteria from the patient's mouth.
Reverse osmosis is the safest and most widespread water filtration process in the world. In this way, uncontaminated water is obtained, free of lime and other unwanted substances.
Chlorine Dioxide (ClO2) is universally recognized as the best disinfectant that science has made available to man.
Oxidizing gas, soluble in water, is already used in many countries to make drinking water and has a bactericidal and virucidal power, capable of dissolving biofilm in the pipes of dental chairs already installed, and is capable of preventing the formation of bacteria in newly installed dental chairs, as it attacks the cell wall of microorganisms and kills them even when they are inactive.
