“…Although all the instruments presented same tip sizes (#25), they had different cross-sections, taper, and thermal treatment of NiTi, which affected their mechanical properties (2,8,12,15,20). In agreement with our results, previous studies have shown that EDM size 25, .08 taper had higher cylic fatigue resistance than thermal treated NiTi instruments, such as PTG, HCM, WaveOne Gold, Reciproc Blue (9,11,12,20).…”

“…Interestingly, with the more severe insertion angle of 30° the thermally pre‐treated instrument Reciproc Blue fractured earlier than the M‐wire instrument, whereas with angles below 30°, the opposite had been measured (Pedullà et al ). The time to fracture from other studies on Reciproc Blue has been reported as 872 s (Keskin et al ), 325 s (De‐Deus et al ) or even 2875 NCF (Gündogar & Özyürek ). This phenomenon is explained by the authors who speculated that pre‐heated Reciproc Blue instruments are more flexible than Reciproc, but can absorb less stress (Pedulla et al ).…”

The endodontic literature contains a plethora of studies on static and dynamic cyclic fatigue resistance tests performed on a large array of rotary or reciprocating nickel–titanium endodontic instruments. It was the aim of this review to summarize the currently available evidence to point out the different outcomes from static versus dynamic tests and to assess whether cyclic fatigue tests provide useful data and information for clinical practice. An electronic literature research in the database PubMed was performed using appropriate search terms, and the titles and abstract were screened for relevance. Language was restricted to English. The review reveals marked differences between the results obtained in static and dynamic tests, and also, the results for the same instruments assessed either under static or dynamic experimental conditions are widely inconsistent. Between the lowest and the highest value for one and the same pathfinding instrument was a factor of about 123 when cyclic fatigue was assessed either under static or dynamic experimental conditions. Moreover, standard deviations of up to 30% have been reported. Environmental temperature has a 500% impact on the lifetime of instruments. In conclusion, fatigue resistance tests conducted under room temperature should be regarded as having little meaning and the scientific and clinical benefits of fatigue resistance tests are very limited. These data should be provided by the manufacturer of the instruments.

“…Only Hyflex EDM files have a significantly increased cyclic fatigue resistance compared with ProTaper Gold, WaveOne Gold and Reciproc Blue (Kaval et al . , Gündoğar & Özyürek ). All four Gold and Blue heat‐treated NiTi systems create well‐centred preparation even in severely curved root canals (Elnaghy & Elsaka , Silva et al .…”
