UMD: Broaches designed to shape and enlarge dental cavities (e.g., root canal) and/or to remove dental tissue. Dental broaches are typically manual, handheld instruments with an elongated, tapered, and serrated working end and a handle. Dedicated dental broaches are used mainly in endodontic procedures to remove intact pulp tissue.
