Mechanical and elemental comparison of EndoStar and One Curve nickel-titanium endodontic files: An
Article in Journal of conservative dentistry and endodontics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To compare the cyclic fatigue resistance, bending behavior, and elemental composition of two heat-treated nickel-titanium (NiTi) rotary file systems, Endostar E3 Azure and One Curve, using standardized Methodology: The study randomly allocated 90 new size 25/0.06 NiTi rotary files ( Results: Endostar exhibited significantly greater cyclic fatigue resistance compared with One Curve, showing higher number of cycles to fracture (2814.3 ± 488.9 vs. 1454.7 ± 452.5; Conclusion: Endostar E3 Azure demonstrated superior cyclic fatigue resistance, higher bending stiffness, and distinct surface chemistry compared with One Curve. Surface elemental variations and heat-treated differences may be associated with the observed mechanical variations; however, mechanistic interpretation requires further phase-transformation analysis.
