Revisiting Premolars Using Cone-Beam Computed Tomography Analysis and Classifying Their Roots and Root Canal Morphology Using Newer Classification.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
objectiveThe objective is to compare the internal morphology of premolars while applying the Vertucci and recent classification system for root canal variations in the Gujarat population using CBCT. MATERIALS AND METHODOLOGY: A sample size of 537 CBCT images collected from various diagnostic centers in Gujarat was analyzed. The root canal morphology was then classified by using two methods - Ahmed et al. and Vertucci classification system. Fisher's exact test and Chi-square test were used for statistical analysis.
resultsAll the premolars revealed a varied canal configuration. More than half of maxillary first and 42% of maxillary second premolars were double rooted. Vertucci type IV classification was the most common in first maxillary premolars and Type I and type IV were commonly seen in second premolars. According to the new system, the code
conclusionPremolars - both maxillary and mandibular - in this subpopulation had a wide range of root canal anatomical variations. Clinicians should be aware of this for a successful treatment outcome. The new system for classifying canal morphology describes the root and canal configurations in a more accurate and practical manner compared to the Vertucci classification and hence can be used routinely.
