GENEVA, Aug 11– The World Health Organization (WHO) on Tuesday advised postponing routine dental checkups until the risk of COVID-19 transmission is better understood, citing potential hazards from procedures that generate aerosols.
As dental practices resume operations in regions where the pandemic is easing, the WHO emphasized the need to protect both patients and staff from potential infection during treatments that produce tiny airborne particles.
“There is currently no data on coronavirus spread from the dentist’s chair,” the organization said, highlighting the need for further research into common dental procedures, including three-way air/water sprays, ultrasonic cleaning tools, and polishing instruments, all of which can release micro-particles into the air.
Benoit Varenne, a WHO dental officer, told a briefing: “WHO guidance recommends, in case of community transmission, prioritizing urgent or emergency oral care, avoiding procedures that generate aerosols whenever possible, and delaying routine non-essential dental care. The likelihood of COVID-19 being transmitted through airborne particles is still unknown, so more research is needed.”
Last month, the WHO issued general guidance on coronavirus transmission. While some reports suggested possible airborne spread, the agency stopped short of confirming it.
The organization also stressed the importance of proper ventilation in dental facilities to reduce virus transmission in closed settings.
Varenne noted that ensuring sufficient personal protective equipment (PPE) for all dental staff remains a top priority.
