There is ample documentation of the transfer of microorganisms onto and into impressions. Organisms can also move into dental casts. Some of these organisms can remain viable for up to 7 days. Again, wearing of proper PPE is required. Incorrect handling of contaminated impressions and casts offers the opportunity for transmission of microorganisms.

Some types of impression materials are sensitive to immersion. Spraying has several advantages. Spraying is the treatment of choice for some impression types; it uses less disinfectant and often is the same disinfectant that a practice uses for environmental surface disinfection. Spraying is technique sensitive. Disinfectant must contact all impression surfaces.
