Angulation

The instrument is to be at a 70 - 80 degree angle to the tooth. This provides the best angle with which to take off calculus without burnishing it. I first use an exploratory stroke to find the calculus and then a working stroke to remove it. This is important because you don't want to be doing unnecessary instrumentation on the tooth.
I find that I know when I have the right angulation because the instrument grabs and you can hear a scraping sound.

Preparation.... H

Just getting ready for boards. Lately I have really started to doubt my abilities!
When it comes down to it, I'm sure I'm going to be fine but it is nerve wracking.

I REALLY need to get better at classifying patients. In real life, your classification of them will be the deciding factor on whether they pay 600 dollars or 150.
I'm not so hot at it....

New position

I learned something today.
When doing lower R sit at 1:00 to reach mesial surfaces
