When we're taking the restorative portion of the board exam, whether it is on the typodont or patient, are we allowed to choose which armamentarium (burs, hand instruments, etc.) to use or are we restricted to use only a certain set? For example, when doing a simple class II amalgam preparation on the typodont, can we use the gingival margin trimmer or do we only have the hatchet available? Or can we use a 330 diamond instead of a carbide?
