Stereomicroscopic evaluation of dentinal microcracks after instrumentation with rotary and reciprocating file systems: An
Article in Bioinformation, 2025. 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
Root canal instrumentation was associated with dentinal microcrack formation in all groups, with no statistically significant differences observed. The single-file reciprocating system showed fewer apical microcracks, while the rotary system demonstrated more apical defects but performed better at the coronal level. Complete fractures were relatively uncommon but occurred more frequently with reciprocating files at the coronal level. These variations suggest that factors beyond instrumentation kinematics, including file design and metallurgy, contribute to microcrack development. Further studies with advanced imaging are needed to validate these findings and assess their clinical implications.
