In our opinion, NiTi Rotary files have been used in the wrong way by the operators over the past twenty years! While much innovation has gone into the design of NiTi files, not enough communication has been made to the end user about how they should be used. With the newly released ESX™ File System by BrasselerUSA, RealWorldEndo has decided to standardize operator motion by explaining to people why a Single Stroke an Clean™ Motion (SSC) makes sense for operators using the ESX™  File System.
