1 · What the graph read from 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.

2 · The registry

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

A foundational grasp of root canal anatomy is vital for achieving predictable treatment and long-term outcomes in endodontics. Untreated canal is the primary cause of persistent apical periodontitis following endodontic therapy. Maxillary premolars with three roots and canals exhibit a rare but clinically significant anatomical variation characterized by a trifurcation on the root. This feature is frequently overlooked and can contribute to endodontic failure if not properly diagnosed and managed. Recognition of such anatomical variations, combined with the use of radiographic imaging, magnification, and ultrasonics is essential for clinicians to ensure predictable and effective endodontic treatment outcomes. Integration of cone-beam computed tomography (CBCT) in endodontics significantly enhances the diagnostic precision and accuracy in identifying such complex anatomies. This case series highlights the strategies in endodontic management of maxillary premolars with trifurcation.
