What instrument is used to file the bone during dental procedures?

• A. Cow horn forceps
• B. Bonefile
• C. Chisile
• D. Disposable prophy angle

Answer: (B)

The bone file is the instrument specifically designed for filing and smoothing bone during dental procedures. It features a series of sharp, narrow blades that allow for precise control when removing or contouring bone tissue. This is particularly important in various surgical procedures, such as when reshaping bone after extractions or preparing for implants. Its design enables dental professionals to achieve a smooth finish on the bone surface, which is critical for proper healing and integration of dental implants.

Other instruments mentioned serve different purposes. For example, cow horn forceps are primarily used for extracting teeth by grasping and removing the root structure, while chisels are employed to cut or shape hard tissues. A disposable prophy angle is designed for polishing teeth and applying prophylactic agents, not for filing bone. Each tool has its specific application in dental procedures, making the bone file the correct choice for this particular function.
