C Files are ideal for negotiating calcified, torturous, or severely curved canals. The files are available in 21- and 25-mm lengths and size Nos. 06, 08, and 10. These allow the practitioner to lean on the instrument more, enabling easier negotiation in extremely narrow or calcified canals. For more information, call (800) 847-4073.

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.

GuttaFlow is the first flowable gutta-percha obturation system that combines gutta-percha and sealer in one material. This self-curing, injectable system works at room temperature (no heating required), ensuring an excellent seal without the shrinkage. With the excellent flow and sealing properties of GuttaFlow, condensation is not required. It comes in single-unit dose capsules that deliver a consistent dosage and minimize contamination. It is also radiopaque and can be removed easily if retreatment or post placement becomes necessary. For more information, call (800) 221-3046 or visit coltenewhaledent.com.
