9-11-07 This morning my patient was a class three and had extremely tenacious calculus. It was so hard to get off and I felt like I did not do anything. It was a great experience though because if I can get that off I can probably get just about anything off! I need to work on not being as afraid to go subgingivally. O did do a great job on following my probe depths to try to know how far down I need to clean. In the afternoon I saw two patients. The first was a 1b and I finished cleaning her. The next was a class two and I did an OD on her. I took digital xrays and they turned out great, it just took me a few attempts to get them right!
