Which statement is true regarding enamel microabrasion?

Enamel microabrasion is a cosmetic dental procedure designed to improve the appearance of teeth by removing superficial discolorations and imperfections in the enamel. The procedure is indeed indicated for the removal of superficial stains or discoloration, which can be due to various factors such as dietary habits, exposure to fluorosis, or developmental issues.

In terms of the depth of enamel removal, studies indicate that approximately 22 to 27 micrometers of enamel can be safely removed during a single treatment session. This precision allows dental professionals to enhance the tooth's appearance without compromising its structural integrity.

Considering all these components, it is evident that each statement accurately describes a valid aspect of enamel microabrasion, affirming that all the elements are correct and thus supporting the conclusion that the combined knowledge from these statements is comprehensive and complete.
