Stainless steel crowns are prefabricated,and their outlines and margins appear very smooth and regular;often,however,these crowns do not appear to fit the tooth well.They have a ghostlike radiopaque appearance on dental images.Silver amalgam two-surface and multi-surface restorations are characterized by their irregular outlines or borders.They are radiopaque.Gold will appear as a large,well-adapted radiopaque restoration with smooth borders.Unlike metallic restorations,which appear totally radiopaque,porcelain restorations are slightly radiopaque and resemble the radiodensity of dentin.
