Abstract

A wall-mounted far ultraviolet-C light device used for continuous air and surface decontamination in a dental office reduced aerosolized bacteriophage MS2 and methicillin-resistant Staphylococcus aureus on steel disks by >3 log10 in 2 hours in unshaded areas in a procedure room. Far ultraviolet-C delivery was substantially reduced in shaded areas.
