#9 – Lab Infection Control

So far, you have learned to be very careful while cleaning / sterilizing instruments and assisting. Now it’s time to apply these same high standards to our lab.

Sterilizing procedures will occur at 2 places.
1. Before the item reaches the lab (example – sterilize impressions)
2. After the item is in the lab
