´╗┐Munce Discovery Burs are the answer to calcified canals, separated instruments, isthmus troughing, cement-line dissection, and deep-access caries. Shallow and deep troughers are 31 and 34 mm, respectively, with 6 easy-to-read, color-coded round carbide head sizes (Nos. 0.25, 0.5, 1, 2, 3 and 4). Stiff 1-mm diameter shafts ensure positive operational control, and the even narrower 0.7-mm diameter stiff shaft of the tiny 0.25 deep trougher makes it ideal for high-magnification, delicate isthmus troughing, and cement-line dissection around posts, silver points, etc. There is also the unique, 31-mm No. 6 endodontic cariesectomy bur. By contrast, standard slow-speed burs are only 28 mm and have bulky 2.6-mm diameter shafts that impinge on deep-access cavity walls, unfavorably guiding the bur head toward ledging or perforation. Unlike ultrasonic tips, Munce Discovery Burs are heatless, not prone to spontaneous breakage, and have the familiar tactile feedback of slow-speed round burs.
