What is the recommended speed for a slow-speed handpiece during coronal polishing?

• A. 10,000 to 15,000 RPM
• B. 20,000 to 25,000 RPM
• C. 30,000 to 35,000 RPM
• D. 40,000 to 45,000 RPM

Answer: (B)

The recommended speed for a slow-speed handpiece during coronal polishing is 20,000 to 25,000 RPM. This speed is optimal because it allows for effective polishing of the tooth surfaces without generating excessive heat, which could damage the tooth enamel or irritate pulp tissue. At this range, the handpiece can adequately deliver the polishing agent and facilitate the removal of plaque and stains, promoting patient comfort and safety. Slower speeds help maintain control and precision, allowing dental professionals to work efficiently while minimizing the risk of damage to both the tooth structure and surrounding soft tissues.
