What should be done if an instrument does not come into contact with a high-level disinfectant?

When an instrument does not come into contact with a high-level disinfectant, it is critical that it be re-sterilized before use. High-level disinfection is essential for eliminating a wide range of microorganisms, including spores, on instruments that come into contact with mucous membranes or non-intact skin. If an instrument has not been properly disinfected, there is a risk of transmitting infections to patients during dental procedures.

Re-sterilization ensures that any potential contaminants are effectively eradicated, thereby maintaining a safe environment for both patients and dental professionals. It emphasizes the importance of adhering to proper infection control protocols, as using instruments that haven't been adequately disinfected can compromise patient safety.

In contrast, using an instrument again without cleaning, discarding it, or assuming it is safe to use if visibly clean do not meet the necessary standards for infection control and can lead to serious health risks. Therefore, it is the procedure of re-sterilizing instruments that upholds the highest standard of patient care.
