Cyclic fatigue of NiTi rotary instruments in a simulated apical abrupt curvature.
AIM To evaluate the cyclic fatigue resistance of five NiTi rotary systems in an abrupt apical curvature. METHODOLOGY Cyclic fatigue testing was performed in stainless-steel artificial canals with a 2-mm radius of curvature and an angle of curvature of 90 degrees constructed to the dimensions of the instruments tested. The middle of the simulated curvature was 2.5 mm from the tip of the instru...
متن کاملCyclic fatigue resistance of rotary NiTi instruments after simulated clinical use in curved root canals.
The aim of this study was to assess cyclic fatigue resistance in rotary nickel-titanium instruments after simulated clinical use in curved root canals (40-degree, 5-mm radius curve). Thirty-six RaCe rotary NiTi files, size #5, taper 0.04, were divided into 3 groups: Groups A, B and C with one, three and five cycles of use, respectively. Time to failure was recorded with a stopwatch in seconds a...
متن کاملComparison of Cyclic Fatigue Resistance of ProGlider and One G Glide Path Files.
INTRODUCTION The aim of this study was to compare the cyclic fatigue resistances of nickel-titanium rotary glide path files, which are manufactured as single-file systems, under dynamic model. METHODS Twenty ProGlider (16.02) and 20 One G (14.03) nickel-titanium glide path files were included in this study. Cyclic fatigue tests were performed with specifically manufactured dynamic cyclic test...
متن کاملCyclic fatigue behavior of nickel-titanium dental rotary files in clinical simulated root canals.
BACKGROUND/PURPOSE Dental rotary instruments can be applied in multiple conditions of canals, but unpredictable fatigue fracture may happen. This study evaluated the fatigue lives of two batches of nickel-titanium (NiTi) dental rotary files operating in clinically simulated root canals. METHODS Single-step cyclic fatigue tests were carried out to assess the performance of two batches of NiTi ...
متن کاملCyclic fatigue resistance tests of Nickel-Titanium rotary files using simulated canal and weight loading conditions
OBJECTIVES This study compared the cyclic fatigue resistance of nickel-titanium (NiTi) files obtained in a conventional test using a simulated canal with a newly developed method that allows the application of constant fatigue load conditions. MATERIALS AND METHODS ProFile and K3 files of #25/.06, #30/.06, and #40/.04 were selected. Two types of testing devices were built to test their fatigu...
