Dental patients and staff need to be protected from any potential infection by aerosol-generating procedures, the World Health Organization (WHO) said on Tuesday, as dentists return to work in areas where the COVID-19 pandemic is easing. "WHO guidance recommends in case of community transmission to give priority to urgent or emergency oral cases, to avoid or minimise procedures that may generate aerosol, prioritise a set of clinical interventions that are performed using an instrument and of course to delay routine non-essential oral health care," Benoit Varenne, a WHO dental officer, told a news briefing. The WHO last month released general guidelines on the transmission of the coronavirus which acknowledged some reports of airborne transmission, but stopped short of confirming that the virus spreads through the air.
