What technique is commonly employed during coronal polishing?

The technique commonly employed during coronal polishing is the rubber cup technique using a slow-speed handpiece. This method is specifically designed for polishing the surfaces of teeth and involves the use of a soft rubber cup attached to a slow-speed dental handpiece. The rubber cup is impregnated with polishing paste that contains fine abrasives. When the handpiece is activated, the cup rotates to smoothly polish the enamel surfaces, effectively removing plaque and extrinsic stains without damaging the enamel.

This technique is favored because it allows for better control and a more comfortable experience for the patient, as the slow-speed ensures gentle contact with the tooth surface. The use of a rubber cup also makes it easier to navigate around the contours of the teeth, achieving a thorough polish while minimizing the risk of applying excessive pressure that could lead to enamel abrasion.

In contrast, other techniques listed, such as high-speed drilling or ultrasonic scaling, serve different purposes in dental procedures. High-speed drilling is primarily used for cutting and preparing teeth for restoration, while ultrasonic scaling is used to remove calculus and debris, not for polishing. Hand polishing with gauze, although it can be used in certain situations, does not provide the same efficacy or finish as the rubber cup technique, making it less common for coronal
