Which category do instruments that contact but do not penetrate soft tissue or bone fall under?

Instruments that contact but do not penetrate soft tissue or bone are categorized as semicritical. This classification is crucial in infection control protocols, as semicritical items come into contact with mucous membranes or non-intact skin but are not used in a manner that would breach or penetrate deeper tissues.

Semicritical items typically require a high level of disinfection to prevent the transmission of pathogens, as they can carry a higher risk than noncritical instruments. However, they are not considered critical, which would include instruments that penetrate soft tissue or bone and thus require sterilization due to their potential to carry more harmful pathogens.

Instruments classified as noncritical come into contact only with intact skin and have a lower risk of transmitting infections. Understanding these categories helps maintain effective infection control practices in dental settings, ensuring the safety of both patients and practitioners.
