Dental broaches designed to enlarge the root canal. An endodontic broach is often one of the first instruments used to perform an endodontic procedure. These devices typically are thin, flexible, manual, handheld instruments with a tapered and pointed working end. They are smooth or, more frequently, have a series of sharply pointed barbed projections curved backward and obliquely and have a handle. Barbed broaches are used primarily to remove intact pulp tissue, while smooth root-canal broaches are also used as explorers.
