What is the correct procedure for instrument bagging in a Type N autoclave?

The correct procedure for instrument bagging in a Type N autoclave involves bagging instruments after the autoclave cycle is complete. This practice ensures that the instruments remain sterile during storage and handling. Once the autoclave has finished its cycle, and all phases (including drying) are complete, the instruments can be safely bagged to protect them from contamination.

Bagging instruments before entering the autoclave would not be appropriate for a Type N autoclave, as the sterilization process needs to occur in the absence of any barriers. Similarly, bagging during the cooling phase could risk contamination from the environment, as instruments need to cool under controlled conditions to maintain sterility. The option stating that no bagging is required overlooks the critical step of ensuring that instruments are protected after sterilization, which is essential for infection control in a dental setting.
