Which instrument would be used for a Class II amalgam preparation but not for a Class V amalgam on tooth #3?

In the context of dental procedures, the use of instrumentation is specific to the type of cavity preparation being performed. For a Class II amalgam restoration, which involves the proximal surfaces of posterior teeth, specific instruments aid in shaping the cavity and ensuring proper placement of the restorative material.

The Miller articulating paper forceps are specifically designed to handle articulating paper, which is used to check occlusion in a restoration. While these forceps are critical for ensuring proper bite alignment after a restoration has been placed, they do not contribute to the preparation or filling of the cavity itself.

In contrast, other instruments listed, such as the explorer, Hollenback, and condensers, are essential for preparing and shaping cavities or condensing amalgam material. The explorer is used to detect caries or irregularities in the tooth structure, the Hollenback is used for carving and contouring restorations, and the condensers are necessary for packing amalgam into the cavity.

Since the Miller articulating paper forceps are not involved in the actual preparation or placement of amalgam material within a Class II cavity, their use would not be applicable to a Class V amalgam preparation, which typically involves the gingival margin of anterior or posterior teeth, therefore making this choice
