- Abstract
Technological innovation and the modernization of manufacturing procedures have thoroughly redefined the field of nickel-titanium (NiTi) rotary and reciprocating endodontic instruments [[1]]. These research methods are described by the currently available ANSI/ADA and ISO specifications, although manual stainless-steel files are stipulated to have been taken as the reference, thus, actually, resulting in them not being suited for assessing the fracture properties of modern NiTi instruments. The mechanical performance of NiTi endodontic instruments is usually investigated with the use of five principal tests: fatigue tests, torsional and angular deflection tests, bending or flexibility tests, and cutting efficiency evaluations [[3], [5], [7]].
