Characterisation of the Mesial Root and Middle Mesial Canal Morphology in Mandibular First Molars: An Ex Vivo Micro-CT Study.

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
This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro-CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio. Twenty-four configurations were found, with the confluent type most prevalent (90.48%). Three separate orifices occurred in 64.29% of teeth, and MMCs were mainly in the coronal and middle thirds. Fully independent MMCs were rare (2.38%). Mean dentine thickness 2 mm below the furcation was 1.31 mm (MB), 1.03 mm (MMC) and 1.28 mm (ML). The mean aspect ratio was 2.90. Accessory canals appeared in 28.58%, and an independent MMC foramen in 38.09%, mainly on the mesial wall. Type III isthmus predominated (52.38%). Mesial roots with MMCs exhibit marked anatomical variability, with thin dentine around the MMC requiring careful endodontic management.
