Structural Analysis of NiTi Endodontic Instruments: A Systematic Review. [PDF]
Iranian endodontic journal, 2020 Irregularities and defects on NiTi endodontic instruments originating from the manufacturing process can lead to the structural collapse and fracture of these instruments during treatment. To assess the cause of instrument wear and fracture, as well as increasing fracture incidence, destructive and non-destructive methods have been used for the ...

Hardness And Strength Of Endodontic Instruments Made From NiTi Alloy
Australian Endodontic Journal, 1998 AbstractScant information could be found in the dental literature on the hardness or strength of the materials in nickel‐titanium (NiTi) root canal instruments. Hardness testing is a convenient method for examining these products and strength properties can be deduced from strength‐hardness data.
