Which device is used for fast tooth preparation by removing enamel and dentin?

• A. Slow straight hand piece
• B. Air turbine handpiece
• C. Round burs
• D. Slow contra-angle handpiece

Answer: (B)

Fast tooth preparation requires a high-speed cutting device. The air turbine handpiece is driven by compressed air and delivers very high RPM, which lets you remove enamel and dentin quickly with burs. A water spray is used to cool the tooth and prevent overheating during rapid cutting. In contrast, slow straight and slow contra-angle handpieces run at much lower speeds and are used for finishing, polishing, or fine shaping, not for fast removal. Round burs are cutting tools that attach to a handpiece, not the fast-cutting device itself. So the air turbine handpiece is the best choice for rapid tooth preparation.
