Leading research at Newcastle University has been used to shape how dentistry can be carried out safely during the Covid-19 pandemic by mitigating the risks of dental aerosols.
It is well known that coronavirus can spread in airborne particles, moving around rooms to infect people, and this has been a major consideration when looking into patient and clinician safety.
Research, published in the
Journal of Dentistry, has led the way in helping shape national clinical guidance for the profession to work effectively under extremely challenging circumstances.
The findings have been used by the Dental Schools Council, Association of Dental Hospitals and the Scottish Dental Clinical Effectiveness Programme to guide key Covid-19 policies for the profession.

Dental procedures can pose a high risk of viral transmission because the tools that are used often produce aerosols, which can contain high numbers SARS-CoV-2 virions, copies of the virus causing COVID-19.
The aerosols are generated when saliva mixes with water and air streams used in dental procedures. As a result, access to routine dentistry continues to be limited during the current COVID-19 pandemic.
Dental practices, which are now back in operation, have had to introduce new room decontamination processes and personal protective equipment measures which have dramatically reduced the number of patients that can be treated in a single day. In particular, dentists need to leave long intervals between treatments, leaving rooms unoccupied to allow aerosols to dissipate. This is limiting patient access and challenging financial feasibility for many dental practices worldwide.
