Comparative analysis of pericervical dentin reduction using three rotary file systems: A micro-computed tomography study.
Article in Journal of conservative dentistry and endodontics, 2025. 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
Background: Maintaining pericervical dentin (PCD) thickness is crucial for the long-term prognosis of endodontically treated teeth. Root fractures are closely linked to PCD loss, which is influenced by the type of rotary file system used. Aims: This study compared the effect of three rotary file systems - TruNatomy, OneShape, and ProTaper Gold - on PCD thickness in the mesiobuccal root of mandibular molars using micro-computed tomography (micro-CT). Materials and Methods: Twenty-seven mandibular first molars were mounted on wax and scanned using micro-CT before and after instrumentation. Samples were randomly divided into three groups ( Results: No significant difference was observed at 4 mm below the CEJ. However, TruNatomy showed significantly less dentin removal at 2 mm ( Conclusions: TruNatomy preserved the most dentin, followed by ProTaper Gold and OneShape. Selecting appropriate rotary instruments can help minimize dentin loss and enhance the longevity of endodontically treated teeth.
