What is the maximum RPM at which a low-speed headpiece operates?

• A. 10,000 RPM
• B. 15,000 RPM
• C. 20,000 RPM
• D. 25,000 RPM

Answer: (C)

The maximum RPM at which a low-speed handpiece operates is typically around 20,000 RPM. This speed is appropriate for various functions such as polishing teeth, removing decay, and finishing procedures where precision is more important than speed. Low-speed handpieces are designed to provide control for the dentist or dental assistant when performing specific tasks that require a gentler touch, making them suitable for working on delicate procedures or in areas that require precision. The other options exceed the standard operational range for low-speed handpieces, as speeds of 10,000 and 15,000 RPM are considered lower still but fall within the typical range; however, they are not the maximum. The 25,000 RPM markup is associated with high-speed handpieces, which are designed for cutting and drilling with a different operational scope.
