Evaluation of root and canal morphology of mandibular molar teeth by cone beam computed tomography: cross-sectional study.
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 6 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
objectivesThe objective of the research was to analyze the differences in root structure found in mandibular molars through cone beam computed tomography (CBCT) and to highlight their morphological features. MATERIALS AND
methodsThis study retrospectively examined CBCT images of 200 patients, encompassing a total of 496 molars in the study group. The frequency of radix entomolaris (RE), radix paramolaris (RP), and C-shaped canals was assessed based on molar type, side, and gender. The data are presented as frequencies and percentages, and the Chi-square test was employed to analyze potential differences between groups. A significance level of p < 0.05 was set for all tests. The normality of the data was assessed using the Shapiro-Wilk test.
resultsThe study included 91 males (47%) and 109 females (53%), with a mean age of 32.49 ± 14.29 years. The frequency of RE was 4.2% (n = 21), RP was 0.8% (n = 4) and C-shaped canal was 7.1% (n = 35) in 496 molars (first molars n = 247, second molars n = 249). RE, RP and C-shaped canal were found in 3.4%, 0.2% and 0.2% of the mandibular first molars, respectively; RE, RP and C-shaped canal were found in 0.8%, 0.6% and 6.8% of the second molars, respectively. There was no statistically significant difference between the root variations examined and gender and lateralisation (p > 0.05).
conclusionsIdentifying anatomical variations in mandibular molars holds clinical importance, as it can improve endodontic treatment outcomes and provide insight into existing failures. Early detection of C-shaped canals and additional root structures can provide more effective cleaning and disinfection processes by more customizing treatment plans.
