When preparing reusable dental instruments for sterilisation, which option shows the correct sequence of cleaning actions?

The correct sequence of cleaning actions for preparing reusable dental instruments for sterilisation is to debride, inspect, rinse, and then scrub.

Starting with debridement involves removing gross debris and contaminants from the instruments, which is crucial to prevent any organic material from interfering with the sterilisation process. After debriding, inspecting the instruments allows the dental nurse to identify any remaining dirt, damage, or wear that could affect the function or safety of the instruments. Following inspection, rinsing the instruments is essential to remove any residual blood, debris, or cleaning agents that might remain after debridement and inspection. Finally, scrubbing the instruments removes any adhering contaminants and ensures that they are thoroughly cleaned, allowing for effective sterilisation.

Using a different sequence, such as starting with scrubbing, might miss the opportunity to remove gross contaminants first, which could compromise the thoroughness of the cleaning process. Each step in the correct order logically builds upon the last to deliver optimal cleanliness and preparation for sterilisation.
