What is the ideal angle for the handpiece during coronal polishing?

The ideal angle for the handpiece during coronal polishing is 90 degrees to the tooth surface. When the handpiece is positioned at this angle, it allows for effective and efficient polishing of the tooth without risking damage to the enamel or gingival tissues. This angle ensures that the polishing tool maintains proper contact with the tooth surface, enabling the removal of plaque, stains, and other debris effectively.

Polishing at the proper angle is crucial for maximizing the effectiveness of the procedure while minimizing the risk of abrasion or unwanted heat generation, which can occur if the angle is off. For optimal outcomes in coronal polishing, establishing this 90-degree position helps maintain control while allowing the dental hygienist or assistant to maneuver the handpiece smoothly and comfortably across the surface of the teeth.
