Rongeurs are specialized surgical instruments designed primarily for the removal of bone and tissue. They function much like scissors but are specifically tailored for grasping and cutting hard tissue rather than soft tissue. Their unique design includes a curved or straight jaw, which allows for efficient cutting and removal of bone during surgical procedures such as orthopedic surgeries, neurosurgery, or any conditions requiring precise removal of bony structures.

In contrast, the other choices involve tasks that require different specialized instruments. Applying sutures typically involves forceps and needle holders, while filling cavities is a dental procedure often done with restorative materials and tools specific to that field. Performing root canals also requires specific endodontic tools for cleaning and shaping the canals, distinctly different from the function of rongeurs. Thus, the focus and design of rongeurs solely support bone and tissue removal, marking them as critical in surgical environments where such action is necessary.
