Immersion of Mtwo nickel-titanium rotary files in antiseptic solution and fatigue resistance: Effects and analysis

Background and aims: Widely application of rotary files for endo treatment would force us to obtain an accurate understanding about the characteristics drawbacks these instruments. Therefore in this study, effects immersion NiTi M2 file deconex sodium hypochlorite solution on cyclic fatigue resistance was investigated Material methods: In exprimental 45 NITI were divided three groups I) control (without any immersion), II) immestion 5 min III) immesrion their by using testing device NCFs recorded. The obtained results analysis Fisher's statistic mean comparisons carried out Tukey Results: showed that streluating solutions provides negative significant cycle highest NCF (890.046) lowest immmersed (546,076). Therefore, it is suggested used autocalve as substitution strelize files.
