1. It's 11 a.m., and you're about to perform a restorative operation on a patient. While caring for the emergency patients earlier in the day, you find that your stock of clean handpieces has run out. So, what exactly do you do?
2. A woman who got her new dentures the day before yesterday has returned to the office in pain. The dentist informs the patient that the denture has to be changed in order for it to fit properly. Describe how you can use a laboratory-type crylic bur with a low-speed handpiece.
3. You note the #2 round bur has dried blood on it when setting up the treatment room for a restorative appointment. What are your plans for the bur, and what is the source of the problem?
