Torsional Testing Of Race, K3 And Profile Nickel Titanium Endodontic Files, Sean D. Fessenden
Torsional Testing Of Race, K3 And Profile Nickel Titanium Endodontic Files, Sean D. Fessenden
Theses and Dissertations
Rotary endodontic instruments have different cross sectional designs that may effect their resistance to torsional stress. The purpose of this study is to evaluate the static torsional properties of two nickel titanium files that have recently been introduced for use in endodontics and compare them to the same size Profile instruments. Ten new files of each brand and size were tested. The files tested were: RaCe 25 tip 0.02, 0.04, 0.06 taper, K3 and Profile 25 and 40 tip in 0.02, 0.04 and 0.06 taper. The diameter of each file was measured at 3mm from tip. The last three millimeters …
