What is the ideal speed for a dental handpiece used in coronal polishing?

• A. 2,000 to 4,000 RPM
• B. 5,000 to 10,000 RPM
• C. 10,000 to 15,000 RPM
• D. 15,000 to 20,000 RPM

Answer: (B)

The ideal speed for a dental handpiece used in coronal polishing is 5,000 to 10,000 RPM. This speed range is effective for polishing the surfaces of the teeth without causing damage to the enamel or surrounding tissues. At this RPM, the handpiece allows for the proper application of the abrasive polishing agent, promoting efficient removal of plaque and stains while ensuring a smooth finish. This controlled speed is crucial because it prevents excessive heat that can lead to sensitivity or injury to the pulp tissue beneath the enamel. Higher speeds, such as those found in some other dental procedures, could be too aggressive for the delicate nature of coronal polishing, which aims to enhance the aesthetic appearance of the teeth rather than remove significant material.
