I set everything up to pass off a handful of PE's. I had called and confirmed my patients and they said they were coming. They didn't come but I found someone to come in. Another 1B woop-dee-doo!! I don't know why all I can get in my chair is 1B's!! I have set up the sealant, diagnodent, airpowder polisher at least 4 times now and have not been able to use them!! I'm ready to go so where is my patient?????
