Dental Radiology Practice Test 2026 – Complete ADAA Intro Prep

Disinfecting contaminated surfaces in the radiographic area is done with chemical disinfectants. After cleaning to remove organic matter, surfaces are treated with an appropriate chemical germicide to inactivate pathogens on inanimate surfaces. Static electricity isn’t a recognized disinfection method, and ultraviolet light isn’t reliable for all surfaces and shadows present in a radiographic area. Heat isn’t practical for room surfaces and could damage equipment. Chemical disinfectants are the standard, effective choice for reducing microbial load on dental radiography surfaces.
