Why is moisture control important during coronal polishing?

Moisture control during coronal polishing is crucial primarily to prevent the mixing of polishing paste with saliva. When saliva enters the polishing area, it can alter the effectiveness of the polishing agents and prevent them from adhering properly to the tooth surface. This dilution can reduce the efficiency of polishing, leading to less effective cleaning and an inferior result. Additionally, maintaining a dry surface enhances visibility and allows for better access to the tooth surfaces being polished, thereby improving the overall quality of the procedure. This focus on moisture control is particularly important in achieving optimal results in coronal polishing, ensuring that the treatment is both effective and reliable.
