What type of restorations can flour of pumice be used on?

Flour of pumice is a mild abrasive agent commonly used in dental polishing procedures, particularly for its effectiveness in polishing various types of restorations. When considering the types of restorations that flour of pumice can be applied to, its versatility becomes apparent. It can be safely used on gold foil and dental amalgam restorations, allowing dental professionals to achieve a smooth finish while avoiding damage to the underlying materials.

Unlike the other options, where restrictions on the types of surfaces are noted, gold foil and dental amalgam represent a range of materials that can benefit from the polishing effect of flour of pumice. This ability to work on metallic restorations is due to the mild abrasive nature of the pumice, which can polish and remove plaque without scratching or damaging these restorative materials. Thus, the broad applicability of flour of pumice makes it a valuable tool in the dental assistant's repertoire for maintaining the appearance and function of restorations.
