Final answer:
Anti retraction valves on dental units and through flushing of the dental lines between patients can minimize the chance of suck back.
Step-by-step explanation:
Anti retraction valves on dental units and through flushing of the dental lines between patients can minimize the chance of suck back.
Anti-retraction valves are designed to prevent the backflow of saliva, blood, and other contaminants into the dental unit's waterlines. This helps to maintain a clean and sterile environment between patients.
By thoroughly flushing the dental lines between patients, any residual debris or contaminants can be effectively removed, further reducing the risk of cross-contamination.
