Cone-beam Computed Tomography Study of the Root Canal Morphology of Lower Incisors.

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
Introduction: The present study aims to evaluate the root canal morphology of permanent lower incisors by cone-beam computed tomography (CBCT) according to Vertucci's classification (1984), and to correlate the findings with sex, age group, and side of the dental arch. Materials and Methods: This was a descriptive observational study that used a sample of mandibular CBCT scans performed between 2021 and 2024 at a private dental radiology service. When none of the Vertucci configurations was applicable, type 0 was assigned. Results: Type I was the predominant morphological configuration, followed by type III, for all variables analyzed. Regarding sex, type I was more common among females (71.1%), while type III accounted for 21.2% in both males and females. With respect to age, type I was more common among minors (76.8%), and type III among older adults (23.3%). The type I configuration was more frequently observed on the right side of the dental arch (70.3%), and type III on the left side (21.9%). Conclusion: The anatomical observations of the lower incisors highlight the need for careful analysis of their internal morphology during endodontic treatment.
