The Past, Present and Future of Endodontic File Design

Dr. John T. Mcspadden

As one of the world’s most prolific and accomplished endo file designers, Dr. John T. Mcspadden has a wealth of insight to share with practitioners and manufacturers alike. Watch as he shares some of the information he presented at the 2016 AAE annual session discussing the historical evolution of endo files, a new major file development for today, and potential file design possibilities for the future.

History of Endodontic Instruments

Dr. ENRICO CASSAI

The first endodontic file was crafted in the mid 1800s by Edward Maynard by notching round wires at first from watch springs and then from piano wires, into files that were capable of removing pulp and debris from teeth.
K-files, which are, to these days, the most commonly used stainless steel hand files in endodontics, were developed by the Kerr company in 1915. Stainless steel hand file techniques, including the step-back, the anti-curvature, the step-down and the balanced force techniques have all been promoted in order to fulfill the instrumentation objectives proposed by Schilder. In 1960 a novel nickel-titanium alloy was developed by William Bueller in Silver Springs, Maryland at the United States Naval Ordinance Laboratory (that is why we often refer to NITINOL where NOL stands for Naval Ordnance Laboratory).

New endodontic files for root canal instrumentation are put on the market non-stop, just like older systems are updated. 
So, what should we expect from the future?
