What type of instruments come in contact with intact skin only?

• A. Critical instruments
• B. Noncritical instruments
• C. Semicritical instruments
• D. Disposable instruments

Answer: (B)

The correct choice is noncritical instruments, which are defined as those that come into contact with intact skin only. These instruments are typically used in procedures where they do not penetrate or come into contact with mucous membranes or sterile tissues, which reduces the risk of transmitting infections. Because they have a lower risk classification, noncritical instruments often require less stringent disinfection practices compared to critical and semicritical instruments. Critical instruments require sterilization because they are used for procedures involving sterile tissue or blood. Semicritical instruments, on the other hand, must be high-level disinfected or sterilized, as they may come into contact with mucous membranes but not sterile tissues. Disposable instruments are designed for single-use, which may not necessarily relate to the integrity of the skin they come into contact with. Understanding these classifications is essential in maintaining proper infection control protocols in dental hygiene practices.
