Q. I'd like to begin using rotary instruments as I do 2-3 endos a day (1 appt). What is the best rotary system to purchase?
A. In regards to recommending a rotary file system, I am very excited about the ProTaper line. The development of ProTaper represented a collaborative effort from Drs. Ben Johnson, Pierre Machtou, John West and myself, along with the Dentsply Maillefer engineers. The ProTaper system is carried by Dentsply Tulsa Dental. There are eight (8) instruments in the set - 3 Shapers and 5 Finishers - so it is a very simple system to learn and use. Tulsa has a CD that comes with the introductory package and I also have published various articles on ProTaper (download articles
). Additionally, my DVD is available through Advanced Endodontics and features all aspects of conventional treatment with emphasis on the ProTaper rotary files for shaping root canals. For your reference, some ProTaper advantages:
1) More efficient cutting edges as these files do not have radial lands.
2) Progressive changing tapers on each shaping file reduces the contact zone between the file and the dentin which improves efficiency and decreases breakage.
3) More flexible than a fixed tapered instrument the same size due to its progressively tapered design.
4) Continuously changing pitch and helical angle reduces the screw effect.
