Class V amalgam restorations may be used anywhere in the
mouth.
Amalgam may be preferred over esthetic restorative
materials on partial denture abutment teeth, because amalgam is more resistant to wear as clasps move over the restoration.
Occasionally, amalgam is preferred when the carious lesion
extends gingivally enough that a soft-tissue flap must be reflected for adequate access and visibility

Easier to place Less expensive Because of its metallic color, amalgam is
easily distinguished from the surrounding tooth structure. Therefore amalgam restorations are usually easier to finish and polish without damage to the adjacent surfaces

Metallic Poor esthetics The preparation for an amalgam restoration
typically requires 90-degree cavosurface margins, specific and uniform axial depths, and incorporation of secondary retentive features, all of which results in a less conservative preparation
