To pass dental anatomy at my school you had better know how to draw pretty darn good. Not only did we have weekly drawing exercises to turn in of all five views of the teeth at various magnifications (ex. draw #30 at 4.5x average values in facial, lingual, mesial, distal, and occlusal views) and draw in the contacts, heights of contour, and pulp canals. We also had various quizzes and test questions having us draw teeth in various views. The last day of regular class we were given 5 minutes to draw two teeth in all 5 views and if you did not do it up to the instructors standards then you either had to remediate the exercise or get held back. About 3/4 of the class had to come back in and redo the exercise.
It sucked because I had never really drawn anything before that class, but I can tell you now I know my dental anatomy better than most probably.
