Final answer:
Coronal polishing is not the complete removal of calculus but rather the removal of tooth stains, plaque, and debris from the tooth surfaces, primarily for aesthetic purposes.
Step-by-step explanation:
False: Coronal polishing is a dental procedure that involves the removal of tooth stains, plaque, and debris from the tooth surfaces. It is typically performed by a dental hygienist using a variety of abrasives and polishing agents, such as powdered white mica, which add a shimmer to the paste and have a mild abrasive action. Although coronal polishing can remove some of the superficial stains and plaque, it is not designed for the complete removal of calculus (tartar), which is firmly attached to the teeth. The removal of calculus requires a different dental procedure known as scaling. Coronal polishing improves the aesthetics of teeth by making them appear cleaner and more polished but does not replace the necessity for thorough cleaning to remove calculus.
