What level of disinfection is typically required for semi-critical items?

• A. Intermediate-level disinfection.
• B. Low-level disinfection.
• C. High-level disinfection.
• D. No disinfection is needed.

Answer: (C)

Semi-critical items are those that come into contact with mucous membranes or non-intact skin but do not penetrate tissues. Because of the potential risk of transmitting infections, these items require a high level of disinfection to ensure all microorganisms, especially more resistant pathogens, are effectively eliminated. High-level disinfection involves the use of chemical agents that can destroy a wide range of organisms, including bacteria, viruses, and fungi, which is crucial for ensuring patient safety in clinical settings. In contrast, low-level disinfection is adequate only for surfaces and items that may come into contact with intact skin and are not intended for more invasive use. Intermediate-level disinfection provides a higher efficacy than low-level disinfection but does not achieve the necessary microbial kill required for semi-critical items. The option indicating that no disinfection is needed overlooks the critical standard of care necessary in dental practices to prevent cross-contamination and the spread of infection.
