How must critical instruments be managed in terms of cleanliness?

Critical instruments are those that penetrate soft tissues or contact bone, requiring the highest level of infection control. They must be sterilized after each use because sterilization is the only method that ensures the complete elimination of all forms of microbial life, including bacteria, viruses, spores, and fungi.

This level of cleanliness is necessary to prevent the risk of transmitting infections in a healthcare setting, particularly in dental practices where invasive procedures are common. Simply sanitizing or disinfecting—procedures that may reduce the number of microorganisms but do not eliminate them entirely—would not suffice for critical instruments. Regular sterilization practices ensure that every healthcare provider can protect patients and themselves by adhering to strict infection control protocols.

Options involving less frequent or less rigorous cleaning methods do not meet the necessary safety standards for critical instruments, highlighting why sterilization after each use is the essential practice.
