Four in a row

I don't want to jinks it, so knock on wood, but today I had no errors on my patient. Thats four in a row. Maybe I am actually starting to figure out this whole scaling thing. My patient was my dad again and I did three quads. He is a hard class two. So I was excited about not missing anything on him cause I know there was actually deposits there. He was such a good patient. The ultrasonic was getting water all over him and he did not even complain. He even let me pass of the air powder polisher PE on him and that is the worst. I would compare it to being sand blasted in the mouth. Thanks dad you are such good sport.
