How often should biologic monitoring of an approved sterilizer be performed?

Biologic monitoring of an approved sterilizer is critical to ensuring the effectiveness of the sterilization process. The standard practice requires that biological indicators be used at a minimum frequency of at least once a week. This routine testing helps verify that the sterilization conditions are consistently met and that the sterilizer is functioning correctly. Weekly monitoring allows for early detection of any potential failures in the sterilization process, ensuring patient safety and compliance with health regulations.

While options suggest varying frequencies, the need for at least weekly monitoring stands out because sterilizers can fail without visible signs, and additional assurance is necessary beyond what might be provided by monthly or less frequent checks. Such monitoring typically involves challenging the sterilizer with spores of a specific microorganism known to be resistant to the sterilization process. If these spores are successfully inactivated, it confirms that the sterilizer is operating effectively.

Implementing biologic monitoring on a periodic basis rather than after each cycle or less frequently provides a balance between practical operational demands and necessary precautionary measures to maintain high standards of infection control in dental practices.
