CDC Issues Health Advisory to the Dental Community
Last week, the Centers for Disease Control and Prevention (CDC)
issued a Health
Alert Network (HAN) Health Advisory to the dental community following
outbreaks of nontuberculous Mycobacteria (NTM) infections in children.
In March 2022, the CDC was notified of a new cluster of suspected
NTM infections in children following dental procedures at a pediatric dental clinic.
Investigation into this cluster is currently ongoing, and preliminary site visit
data report that dental unit waterline testing results showed microbial counts
much higher than the level recommended by CDC.
The
CDC recommends that all dental unit waterlines be treated regularly with disinfectants
to meet the Environmental Protection Agency (EPA) regulatory standards for drinking
water (i.e., ≤500 colony forming units (CFU)/mL of heterotrophic water bacteria).
Dental providers should also consult with their dental equipment manufacturer
for appropriate methods and equipment necessary to both maintain and monitor the
quality of dental water. The CDC also provided the Food and Drug Administration’s recommendations for infection
control procedures for dental unit waterlines for both dental practitioners and dental equipment manufacturers.
The CDC went on to provide additional recommendations geared
towards dental providers, dental facilities and medical providers.
