Why is moisture control important during coronal polishing?

Moisture control during coronal polishing is crucial primarily to prevent aspiration of debris and to maintain a clear field of operation. When polishing teeth, water and polishing paste can produce aerosolized particles and debris that may inadvertently be inhaled by the patient. Effective moisture control, such as using suction or a dental dam, helps to minimize these risks. It also aids in keeping the area clean, allowing the dental professional to clearly see the working field and ensure that the polishing is performed effectively without obstacles.

While other answers touch on aspects related to comfort or efficiency, they do not address the direct impact on patient safety and the clarity of the working area, which are essential for a successful and safe coronal polishing procedure. Maintaining moisture control is fundamental for both procedural effectiveness and patient protection.
