Hi.
The second item in my posting is regarding the Class II restoration on a mandibular 1st molar which I believe was assigned in the last RT exam. Some people opted to extend the outline form and proximal box to include the distobuccal cusp, and some didn't. Anyway, I dug a little bit into my old textbooks and did not find the design there. If I did include the DB cusp and fail the exam, I cannot cite any textbook
🙂 So I am thinking of just sticking to the old design and criteria (0.5 mm clearance), and not cut the DB cusp more than what is needed. After all, I might be having problems condensing amalgam in this prep with the DB cusp gone. Is this a safe presumption? C'mon guys, I'm a little confused here. Mommyr, what did you do for your class II?
Anyways, for some of you who would be interested to find out how a modified Cl II prep on 19/30 is done, I suggest you cut and paste the following link to your address bar:

Please tell me what you think. Looking forward to hear from you.
