Which handpiece is designed for slower speeds and precision finishing tasks?

• A. Rubber dam frame
• B. Slow contra-angle handpiece
• C. Air turbine handpiece
• D. Slow straight hand piece

Answer: (B)

Slower-speed handpieces are built for control and precision during finishing and polishing. The slow contra-angle handpiece is specifically designed for these tasks because its angled head allows you to reach tricky areas with a gentle, controlled motion, giving you better visibility and maneuverability in confined spaces. At low RPM, it delivers higher torque, so you can refine contours, smooth surfaces, and polish without removing too much material.

In comparison, an air turbine runs at very high speeds and is meant for rapid cutting rather than finesse. A slow straight handpiece can perform finishing, but its straight design limits access and control in tight or multi-angled areas. The rubber dam frame is for isolation, not a handpiece.
