  • Both suction hoses lead to two connections on the assistant's side of the treatment chair on the side of the so-called spittoon and from there they are first passed on inside the chair via pre-filters for suction lines, which are concealed in the floor of the treatment room to a central system usually located in side rooms of the practice lead, which usually takes over the suction of several treatment rooms together.
  • Aerosols are created both during normal exhalation and, in particular, with many dental treatment measures, such as the use of water-cooled or air-powered handpieces and contra-angles, turbines, multifunctional syringes and air/water-powered powder jet devices, etc., which expel the aerosol clouds and thus germs out of the patient's mouth into the surrounding air, where, in contrast to droplets, which quickly fall to the ground, they remain in the air as the smallest floating particles, sometimes for several hours hover and thus pose a significant risk of infection for both the treatment staff and other patients in the practice.
