Exploring anatomical variations of mandibular premolars and their clinical management: a case series.
Article in Frontiers in dental medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Anatomical variations in root canals pose significant challenges and may affect the course of treatment. Mandibular premolars usually have a single canal with single root. However, this case series highlights three mandibular premolars with distinct canal configurations. The first case involved a mandibular second premolar with Sert and Bayirli Type IX anatomy, characterised by one canal trifurcating into three different canals at the apex. In the second case, the Vertucci Type V configuration is in the mandibular second premolar. In the third case, a mandibular first premolar showed a Vertucci Type IV configuration, which remained distinct throughout its course. Cone-beam computed tomography (CBCT) is a reliable diagnostic tool for identifying these intricate canal morphologies. The use of magnification ensured through biomechanical preparation and obturation, which contributes to the success of endodontic therapy.
