Airflow® and how to reduce aerosols

Описание: HOW CAN THE CONTAMINATION OF DENTAL AEROSOLS BE REDUCED?
It is well documented that the use of a pre-procedural mouth rinse with a CHX A solution for 30 - 60 seconds reduces the bacterial load in the aerosols by up to 70%. However, CHX shows low effectiveness against corona viruses. Hydrogen peroxide (H2O2) at a concentration of 0.5% or more is proven to effectively kill viruses. EMS has collaborated with experts from the fields of dentistry and chemistry, to develop a mouth rinse solution ViruProX®. This new solution contains H2O2 (1.5%) and CPC B (0.05%) which efficiently kill viruses in addition to bacteria. We recommend that patients gargle and rinse with ViruProX® for 60 seconds at the beginning of each treatment. This process should be repeated, if possible after 30 minutes.

The correct use of mouth-nose protection masks, goggles and face-shields as well as the efficient and safe sterilization of instruments is mandatory. AIRFLOW® and PIEZON® handpieces and all Instruments (PS) should be sterilized after each treatment. The surface disinfection and regular rinsing of the suction system are further obligatory measures. Good ventilation of the treatment rooms after each patient is strongly recommended.

HOW CAN THE FORMATION OF AEROSOLS BE REDUCED?
Nearly all dental instruments used in common treatments generate aerosols: low- and high-speed handpieces, turbines, sonic- and ultrasonic devices, air water syringes, and air polishing devices. The use of a high-vacuum suction system with a suction volume of at least 300 l/min, in combination with an optimal saliva ejector can effectively reduce aerosol formation. Four-handed dentistry allows optimal suction. When working two-handed for professional mechanical biofilm removal, a skilled suction technique in combination with Optragate® supports reduction of aerosols very well.
