Trifid nasopalatine canal: case report of a rare anatomical variation.
Article in Radiology case reports, 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
The nasopalatine canal (NPC) is a critical anatomical structure in the premaxilla, housing neurovascular components essential to maxillofacial surgery. While typically presenting as a single or bifurcated canal, rare variations such as a trifid configuration can complicate dental implant placement. This case report describes an incidental finding of a trifid NPC in a 38-year-old male during a pre-implant cone-beam computed tomography (CBCT) evaluation. The CBCT revealed 3 distinct canals with symmetrical distribution, visible in axial, coronal, and sagittal views, converging at the incisive foramen without associated pathologies. This rare anatomical variant necessitated adjustments in the surgical plan to minimize risks of nerve injury and ensure implant stability. The case underscores the importance of CBCT in identifying complex NPC morphologies for optimizing surgical outcomes and highlights the need for further research into the prevalence and clinical implications of such variations.
