Intermediate level disinfectants include which of the following?

Intermediate level disinfectants are characterized by their ability to kill most bacteria, viruses, and fungi, but not necessarily all bacterial spores. The correct choice identifies disinfectants such as phenolics, iodophors, and chlorine-containing compounds that fit this classification.

Phenolic compounds are effective against a broad range of microorganisms and are widely used in dental settings. Iodophors are another group that provides disinfecting properties, particularly for surfaces, as they release iodine to kill a variety of pathogens. Chlorine-containing compounds, like bleach solutions, are effective in killing bacteria and viruses, making them suitable for intermediate level disinfection.

These disinfectants are essential in dental practices to ensure that instruments and surfaces are properly decontaminated before and after patient procedures. Their ability to combat a wide spectrum of pathogens while being more effective than low-level disinfectants makes them essential in infection control practices in dentistry.
