What is the primary function of a Rongeur in dental procedures?

To extract teeth
To cut and trim alveolar bone
To fill cavities
To measure tooth alignment

The correct answer is: To cut and trim alveolar bone

The primary function of a Rongeur in dental procedures is to cut and trim alveolar bone. This specialized instrument is designed with a hinged jaw that allows it to grip and remove small pieces of bone, making it particularly useful in surgical situations where access to the bone is necessary. For example, during procedures such as tooth extractions or periodontal surgeries, the Rongeur helps in shaping the bone to facilitate better healing and proper alignment for further dental work or implants. This differentiates it from other instruments used in dentistry, such as extraction tools that are specifically designed for tooth removal, or instruments used for filling cavities, which focus on restorative tasks. Additionally, while measuring tooth alignment is crucial in orthodontics, it involves different tools that are not intended for bone manipulation. Thus, the Rongeur’s design and function uniquely position it for the important role of handling alveolar bone in various dental surgical procedures.
