Which procedure is normally performed before coronal polishing in orders to clear the enamel surfaces?

The procedure typically performed before coronal polishing to clear the enamel surfaces is scaling. This process involves the removal of plaque, tartar, and surface stains from the teeth. Scaling is an essential step because it ensures that the enamel is clean and smooth, which is critical for effective polishing. If the surface of the teeth is not free of deposits, the polishing procedure may be less effective, and residual plaque can lead to further dental issues.

Other options, such as polishing and flossing, do not serve the same preparatory purpose. Polishing is the act that follows scaling, enhancing the surface's sheen after it has been thoroughly cleaned. Flossing is an important daily oral hygiene practice designed to clean between the teeth but is not a procedure that prepares the enamel surface for polishing. Restoration refers to procedures aimed at repairing or replacing damaged teeth, and while these might be necessary at other times, they do not relate directly to the process of preparing for coronal polishing.
