What is the difference between coronal polishing and ultrasonic scaling?

Coronal polishing is a procedure aimed at removing extrinsic stains from the surfaces of teeth, primarily through the use of a polishing agent and rotary instruments. This technique is effective in enhancing the aesthetic appearance of teeth by eliminating surface stains that may be caused by dietary habits, tobacco use, or other factors.

On the other hand, ultrasonic scaling is a dental cleaning procedure that focuses on removing calculus, or tartar, which accumulates on teeth due to plaque that has hardened over time. This method utilizes ultrasonic vibrations combined with water to break down and remove the calculus deposits that can lead to periodontal disease and other dental issues.

The distinction lies not only in the purposes of the two procedures but also in their methodology. Coronal polishing is less invasive and is largely cosmetic, while ultrasonic scaling is therapeutic and targets the removal of hardened deposits that cannot be removed with polishing. This difference highlights the specific roles each procedure plays in maintaining oral health and hygiene.
