Winter is the season of rapid transmission of COVID-19. When visiting the stomatology department, patients need to take off masks, and a large amount of water mist, droplets, aerosols, etc. are usually produced during treatment. The virus or bacteria in the patient's mouth are often scattered into the air and then attached to various objects in the diagnosis and treatment space. Although various clinics routinely disinfect various items in the diagnosis and treatment space, especially relatively small instruments like dental handpieces, they are often not completely disinfected.

In this critical period, how to do well in disinfection?
