The Endodontic Cariesectomy Bur (31mm) has a #6 round carbide head and was designed to facilitate the type of deep caries removal often required in endodontic cases, and for which there was previously no comparable instrument.
This bur—often in combination with the #4 Shallow Trougher—is ideal for caries removal from around crown margins from within the access cavity.
