How often should biological monitoring of an autoclave be performed?

Biological monitoring of an autoclave should be performed weekly to ensure that the sterilization process is effective. This practice involves using biological indicators, which typically contain spores of heat-resistant bacteria, to confirm that the autoclave has achieved the necessary conditions for sterilization. Weekly testing allows for prompt identification of any issues that may arise, providing assurance that instruments and materials are being properly sterilized and are safe for use.

Conducting biological monitoring less frequently, such as monthly or yearly, may not provide sufficient oversight, as problems with the sterilization process could go undetected for extended periods. Daily monitoring, while it might seem thorough, is generally not necessary and may not be practical for most dental practices. Therefore, the recommended practice of weekly biological monitoring strikes the right balance between thoroughness and practicality, ensuring patient safety without overwhelming the operational capacity of the dental facility.
