How should the operator’s hand be positioned during coronal polishing?

The operator's hand should be positioned in a stable manner that allows for controlled movements with a light grip. This is crucial because a stable hand helps to maintain precision while polishing, reducing the risk of applying too much pressure on the teeth or causing discomfort to the patient. A light grip ensures that the operator can easily make adjustments as needed without straining the hand or wrist, which is important for both the operator's comfort and the effectiveness of the polishing procedure.

A tight grip could lead to fatigue, lessen control, and create a possibility of over-polishing, while a relaxed and loose grip might not provide the necessary stability needed for precise movements. An elevated position may improve visibility, but it can also lead to awkward hand positions that compromise control and comfort during the procedure. Overall, a stable hand with a light grip facilitates effective coronal polishing by providing the balance between control and ease of movement needed for optimal results.
