A Comparison of Apical Transportation Between FlexMaster and Twisted Files Rotary Instruments

Journal of Endodontics, 2012
The aim of this study was to evaluate apical transportation in root canals after the use of Twisted Files (TF; SybronEndo, Orange, CA) and FlexMaster (VDW, Munich, Germany) #40/04 rotary files.A double-digital radiographic technique was used to compare apical transportation between the TF and FlexMaster systems.

Torsional properties of twisted and machined endodontic files

Journal of Endodontics, 1990
The torsional properties of conventionally twisted K-type endodontic files and recently developed machined K-type endodontic files were compared. File sizes 10 through 40 were subjected to torsional load in clockwise and counterclockwise directions independently.

Comparison of Canal Transportation and Centering Ability of Twisted Files, Pathfile-ProTaper System, and Stainless Steel Hand K-Files by Using Computed Tomography

Journal of Endodontics, 2010
The purpose of this study was to compare canal transportation and centering ability of 2 rotary nickel-titanium (NiTi) systems (Twisted Files [TF] and Pathfile-ProTaper [PP]) with conventional stainless steel K-files.Ninety root canals with severe curvature and short radius were selected. Canals were divided randomly into 3 groups of 30 each.
