Anatomical features of mandibular second molar C-shaped root canals in a Chinese population: a CBCT analysis.

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
purposeC-shaped root morphology features narrow canals, root concavity, and thin dentinal walls, necessitating careful treatment planning and clinical expertise for effective cleaning and shaping.
methodsThis study included 401 total CBCT images of mandibular second molars with C-shaped root canals. Root morphology, root length, dentin thickness, and the location, length, width, and depth of the radicular groove were all analyzed with the Planmeca Romexis 3.1.0.R software. Fan Bing's C-shaped root canal classification method was used to classify all data, and SPSS was used for statistical analyses.
resultsThese analyses revealed significant differences in radicular groove for mandibular second molars with C-shaped root canals across different root canal cross-sections. The mean respective root and radicular groove lengths for the analyzed molars were 11.64 ± 1.42 mm, and 9.34 ± 1.42 mm, and coronal, middle, and apical radicular groove incidence rates were 94.51%, 100%, and 98.75% respectively. The observed radicular grooves were widest at the coronal level and deepest at the middle level, while dentin was thinnest at the apical level.
conclusionsThis study offers an overview of the radicular groove characteristics in mandibular second molars with C-shaped root canals, providing anatomical data to assist clinicians in root canal treatment.
