The AIRFLOW® treatment with the use of Optragate, a suitable mouth rinse and high vacuum suction does not lead to an increased risk of bacterial contamination for the practice team and patients. It is imperative to strictly follow the RKI guidelines and recommendations for personal protective equipment, for surface disinfection as well as for the correct technology and proper use of the equipment. The smear infection has been known for a long time and is controlled by the dental team through their protective measures. The risk of infection with these droplets is the smear and not the aerosol infection. These remain in the treatment environment and are not part of the aerosol. It was not the aim of the investigation to collect and measure larger droplets. The contribution of the mouthwash or high vacuum suction to this result was not determined. N.S.: no significant difference (P > 0.05). Group 1: no treatment (control) Group 2: AIRFLOW® treatment with saliva ejector, without mouth rinse, without high vacuum suction Group 3: AIRFLOW® treatment with saliva ejector, with mouth rinse, with high vacuum suction. 2 Box plot of the contaminated aerosol during the ten-minute treatment period. With the use of mouthwash and high vacuum aspir-ation, the AIRFLOW® treatment did not lead to a higher level of bacterial aerosol contamination in the room air.įig. Due to their smaller particle size ( 0.05). Aerosols differ from droplets and spray mist. Nearly all dental instruments used in common dental treatments generate aerosols: low and/or highspeed handpieces, turbines, sonic and ultrasonic devices, air-water spraying and powder-water jet devices. Today, the risk of SARS-CoV-2 must also be successfully managed. In recent decades, dentists have dominated the risk of influenza, tuberculosis, hepatitis and AIDS. For these reasons, very strict hygiene rules have always been applied in dentistry. The main transmission pathway of bacteria and viruses is saliva droplets. In dentistry, the short distance to the patient’s oral cavity means a basic exposure to the patient’s saliva, blood, aero sols and sulcus fluid. Anyone who has chosen a profession in dentistry was aware that dental treatment always involves the risk of infection. Patients, dental staff and dentists are exposed to bacteria and viruses, which can lead to infectious diseases, especially of the oral cavity and the respiratory tract. SARS-CoV-2) in the aerosol, the data show an impres-sive reduction of the bacterial contamination of the room air if the AIRFLOW® treatment is carried out with appropriate protective measures. Although the results of this investigation cannot be transferred analogously to a possible viral load (e.g. Dentists and scientists, supported by EMS, have measured bacterial contamination of room air during an AIRFLOW® treatment in two scenarios (without and with special protective measures).
