What is an example of a semi-critical item in dental practice?

In dental practice, semi-critical items are those that come into contact with mucous membranes but do not penetrate body tissue. This category includes items like mirrors and impression trays, which are essential for various dental procedures. Because these items may encounter potential pathogens present in the oral environment, they must be appropriately sterilized or disinfected after each use to ensure the safety of both patients and healthcare providers.

In contrast, instruments that touch only intact skin are classified differently, as they pose a lower risk of infection transmission. Disposable items are designed for single use to eliminate the risk of cross-contamination, while storage items typically do not come into direct patient contact in a manner that would categorize them as semi-critical. Understanding these classifications helps dental professionals implement effective infection control measures tailored to the specific risks associated with different types of items used in practice.
