Multimethod Analysis of a Novel NiTi Rotary System: Cyclic Fatigue, Buckling Resistance, and Bending Tests.
Article in European journal of dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Instruments are susceptible to deformation and/or fracture, which may represent a failure in endodontic treatment. This study assessed the mechanical properties of nickel-titanium rotary instruments through cyclic fatigue, buckling resistance, and 45° bending tests.One hundred and twenty rotary instruments were divided into three groups: Super Flexi Files Blue (SFB; 20/.04), TruNatomy Small (TN; 20/.04), and ProTaper Ultimate Shaper (PTU; 20/.04). They underwent cyclic fatigue tests at fixed and manufacturer-specified speeds, along with buckling and bending tests.SFB files exhibited the greatest cyclic fatigue resistance with the longest time to fracture and highest number of cycles to failure (NCF), followed by TN and PTU. For PTU and TN, reducing rotation speed increased time to fracture and NCF, while SFB showed reduced values with speed increase. TN exhibited the highest buckling resistance, whereas speed significantly affected cyclic fatigue resistance, with SFB being the most resistant overall. TN demonstrated notable buckling resistance and flexibility.The rotational speed significantly affects the resistance of instruments to cyclic fatigue and that the SFB file is the most resistant file to cyclic fatigue.
