What is one reason to dry instruments after scrubbing them?

Drying instruments after scrubbing them is crucial in preventing corrosion. When metal instruments come into contact with water, moisture can lead to rust and degradation of materials, particularly if they are made of steel or other susceptible metals. Moisture can also interact with any residual contaminants or chemicals present on the instrument, potentially creating an environment that fosters corrosion.

While making instruments easier to store, preparing them for immediate use, or enhancing their appearance are relevant factors in instrument care, they do not directly address the primary concern of maintaining the integrity and longevity of the instruments. Preventing corrosion is vital to ensure the instruments remain safe and effective for future dental procedures, thereby protecting both the healthcare provider and the patient.
