Metal impression trays are classified under which infection control category?

Metal impression trays fall under the category of semi-critical items in infection control. This classification is important because semi-critical instruments come into contact with mucous membranes or non-intact skin, which can potentially transmit infections if not properly sterilized.

Metal impression trays are often used in dental procedures to create molds of teeth and soft tissues, meaning they will contact areas in the mouth that are more susceptible to infection than intact skin. Because they can tolerate heat sterilization methods such as autoclaving, they should be cleaned and sterilized between uses to ensure patient safety and prevent cross-contamination.

Understanding this classification helps dental healthcare providers implement appropriate sterilization protocols tailored to the specific risks associated with the items they use. This knowledge ultimately contributes to maintaining a safe and hygienic environment for patients and practitioners alike.
