COVID-19 and dental practice

Nobody could fail to miss the media coverage about novel coronavirus COVID-19, with daily and sometimes hourly updates about the ‘killer virus’. What exactly does it mean for dental practices in the UK?

In relation to this, Tim Sandle has written an article. Here is an extract:

"As coronaviruses have a lipid envelope, a wide range of disinfectants are effective. Human coronaviruses can be efficiently inactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. Other biocidal agents such as 0.05-0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate are less effective. A virucidal, ethanol-based disinfector/cleaner such as mikrozid liquid could play a useful role in the cleaning and disinfection of hard surfaces, particularly as it is effective against enveloped viruses within one minute."
