When performing extirpation of vital pulp, which tool is advised for wide canals?

The recommended tool for extirpation of vital pulp in wide canals is a barbed broach. The barbed broach's design allows it to effectively engage and remove the pulpal tissue. The barbs on the broach help in grasping the soft tissue within the canal, making it particularly useful for navigating through the wider space of a canal. This tool is beneficial because it provides a better grip and can remove necrotic or infected tissue more efficiently, which is essential in endodontic procedures aimed at preserving the tooth structure while effectively treating the pulp.

In contrast, while smooth broaches, small K-Type files, and reamers serve important functions in endodontic treatment, they are not as effective for this specific purpose in wide canals. Smooth broaches lack the barbed surface needed to grasp pulp tissue, small K-Type files are typically used for shaping rather than for extirpation, and reamers are more suited for canal shaping and enlargement rather than direct tissue removal. This makes the barbed broach the most suitable choice for efficiently extirpating vital pulp in wider canals.
