Dentsply Spiro Short Barbed Broaches

• The barbed broach is formed from a tapered round shaft by lifting up portions of metal of the shaft almost at a right angle to the shaft.
• These elevated barbs will engage the pulp tissue and remove it from the canal.
• In its use, the largest size broach which will fit freely – loosely – in the canal is selected.
• A broach must not engage the canal walls as it is advanced, or the pressure on the barbs will flatten them against the shaft; as the instrument is withdrawn, the barbs will then embed themselves in the walls, making it difficult or impossible to remove the broach.
• Because the barbs are “nicked” out of the shaft this is an extremely fragile instrument and will break easily if misused. It must fit loosely.

• A Barbed broach is an instrument manufactured from round wires, and the smooth surface is notched to form barbs.
• The barbed broach is an extirpating, NOT an enlarging instrument.
• ‘Barbs’ on the broach snag the pulp to facilitate removal.
• The barbed broach must only be used in the straight part of the canal and insertion of the broach should not exceed 2/3rd the length of the canal.

INDICATION:

• Used to remove pulp tissue during endodontic(root canal) treatment.
• They are also used to loosen debris in a necrotic canal or to remove paper points or cotton pellets.

ADVANTAGE:

• Remove soft tissue from the canal.
• Designed to cut tissue when pulled from the canal.
• Color-coded handles.
