Root and canal morphology of mandibular second molars in a Chinese Kazakh population by cone-beam computed tomography.
Article in BMC oral health, 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
objectiveThis study aimed to investigate variations in root and canal morphology of the mandibular second molars in a Chinese Kazakh population using cone-beam computed tomography (CBCT).
methodsA total of 374 mandibular second molars from 236 patients were included in the retrospective study. The mandibular second molars were categorized based on the radiographic morphology of their external roots: non-fused roots (NFR), fused roots (FR), and single roots with a single canal (SS). The configuration of the C-shaped canal at three different levels was categorized into C1-C5. A chi-square test was employed to assess the association between the incidence of C-shaped root canals and demographic factors such as sex and tooth position.
resultsMandibular second molars typically had two roots. C-shaped root canals appeared in 33.1% of second molars. The C-shaped form was most prominent in C3, followed by C1. Sex and tooth position did not exhibit notable differences.
conclusionsThe incidence of C-shaped root canals in the Chinese Kazakh population was similar to that previously reported in Asian populations and higher than in Caucasian and Middle Eastern populations.
