Which disinfectant is suitable for routine cleaning of work surfaces and as an impression disinfectant?

The correct choice is aldehyde, which is effective for routine cleaning of work surfaces and as an impression disinfectant due to its broad-spectrum antimicrobial activity. Aldehydes, specifically formaldehyde and glutaraldehyde, are known to be effective against bacteria, viruses, and fungi. This makes them suitable for high-level disinfection in a dental setting, where maintaining strict hygiene standards is paramount.

Their application extends beyond surface cleaning; they can also effectively disinfect impression materials, which can harbor pathogens if not adequately treated. The high efficacy of aldehydes in penetrating biofilms and their residual antimicrobial activity allow for ongoing protection between cleanings.

Other disinfectants, while useful for specific applications, may lack the same broad-spectrum capability or effectiveness in all scenarios faced in a dental practice. For instance, chlorhexidine gluconate is primarily an antiseptic for pre-operative skin disinfection and has limited effectiveness as a surface disinfectant. Isopropyl alcohol, although it has some disinfectant properties, is less effective against certain types of bacteria and viruses when compared to aldehydes. Sodium hypochlorite is a powerful disinfectant but can be corrosive and may not be suitable for all surfaces or materials used in dental practices. Thus, alde
