Comparative Evaluation of Canal Centering Ability and Transportation of MiniKUT and TruNatomy Rotary File Systems in Curved Root Canals: A Cone-Beam Computed Tomographic Study.
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. 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
Objectives: The current in vitro analysis was designed to compare the centering ability and transportation of MiniKUT and TruNatomy files on the curved mesiobuccal root of the mandibular first molars using cone-beam computed tomography (CBCT). Materials and Methods: Thirty extracted mandibular first molars were randomly divided into two groups. In the first group, root canal instrumentation was performed by MiniKUT, and in the second group, TruNatomy rotary files were used. CBCT analysis of pre- and post-instrumented teeth was performed to check the canal transportation and centering ability at distances of 3, 6, and 9 mm from the root apex with the help of a prevalidated formula. Statistical Analysis: Descriptive statistics were performed to calculate the mean and standard deviation. One-way ANOVA followed by post hoc Bonferroni correction was used to check the association at different levels. Pearson's correlation analysis was performed to assess the relationship between the groups. Results: A significant association was reported with centering ability at 3, 6, and 9 mm ( Conclusion: Both MiniKUT and TruNatomy files demonstrated minimal root canal transportation and maintained canal shape at 3, 6, and 9 mm from the apex. These characteristics suggest that both systems are safe and effective for the instrumentation of curved mandibular canals.
