Due to the nature of dentistry, dental practices are prime settings for the airborne transmission of infection.

Certain dental instruments, such as high-speed drills and ultrasonic scalers,[i] produce aerosols and droplets during dental treatment. These contain organic solid and liquid particles, such as blood, saliva and dentine, and can therefore harbour viruses and/or bacteria.[ii] For both dental professionals and patients, these pathogens pose a significant risk.

Eschmann recognises the importance of clean air in the dental practice – they offer professionals medical-grade Novaerus air disinfection devices, featuring the unique, patented NanoStrike technology.

Have you thought about your air quality?

The impact of aerosols within dentistry has been researched previously, but since the COVID-19 pandemic, there has been an abundance of research regarding aerosols, droplets and the spread of the SARS-CoV-2 infection. Air disinfection has always been integral, but many clinicians have no doubt reconsidered their protocols to ensure that the systems they have in place provide the most reliable protection.

Aside from the SARS-CoV-2 infection, there are other pathogens that can be transmitted through the air flow from aerosols, including bacteria such as Streptococcus, Staphylococcus and Mycobacterium tuberculosis.[iii] This is concerning for all patients, but especially for those deemed vulnerable, such as immunocompromised or elderly individuals.i The dental team are likewise at an increased risk, as they spend long hours within the dental practice, often in enclosed surgery rooms and/or in constant close contact with patients. Alongside aerosols and droplets produced during dental procedures, sneezing, coughing and talking can also release pathogens into the airflow, putting dental staff at further risk.[iv]

Ventilation is a well-established method for improving the quality of indoor air,iii however ventilation may not be viable for every dental practice. Air disinfection units are another option that can help to improve air quality in dental settings. 

Novaerus air disinfection technology from Eschmann provides the first line of protection against viruses and bacteria. How does it achieve this?

Technology you can depend on

With advanced, patented NanoStrike technology, Novaerus safely inactivates all airborne microorganisms on contact and at DNA level in a sub-second time frame.

NanoStrike technology is backed by independent laboratory studies, clinical trials and real-life case studies, demonstrating its efficacy in reducing airborne viruses, bacteria, mould spores, volatile organic compounds (VOCs) and particulate matter. It has also been tested to reduce 99.9% of MS2 Bacteriophage, which is a common surrogate for SARS-CoV-2.[v]

The Novaerus units produce no harmful by-products, and are suitable for 24/7 operation, even around the most vulnerable. There’s also minimal installation (Novaerus units are plug and play) and low running costs, making Novaerus an economical option for dental practices of all sizes.

You can choose between: Novaerus Protect 200, which features a single-speed fan and is perfect for smaller indoor spaces; or the Novaerus Protect 800, which features a 2-speed fan making it the ideal choice for larger indoor spaces. The Novaerus Protect 800 can also be free standing, placed on a wheeled stand or a table-top stand. This way, you have the option to place your system where it will offer the best protection

Whether for a small or large dental practice, Novaerus air disinfection units are suitable for a variety of needs and requirements.

Air quality made simple

When it comes to air disinfection, you need a tried and trusted system. Novaerus air disinfection units from Eschmann allow you to protect your patients and staff, and make safe, disinfected air part of your practice’s infection control protocols.
