Clinical Significance of Mesiobuccal and Distobuccal Canal Variations in Maxillary Molars: A Case Series and a Mini Review.
Article in Case reports in dentistry, 2025. 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
Endodontic treatment success is contingent upon the comprehensive identification and management of all root canals within a tooth's complex anatomy. This is particularly challenging in maxillary molars, which exhibit significant variability in canal morphology. While the presence of two canals in the mesiobuccal (MB) root is well documented, the occurrence of a third canal (MB3) is less common yet clinically relevant. Additionally, the distobuccal (DB) root, typically containing a single canal, may occasionally harbor a second canal (DB2). This case series presents clinical cases that highlight the prevalence and significance of MB3 and DB2 canals in maxillary molars. The findings underscore the necessity for meticulous canal detection using advanced imaging techniques such as cone beam computed tomography (CBCT), as traditional diagnostic methods may overlook these anatomical variations. By sharing these cases, we aim to enhance awareness and encourage further research into the implications of these additional canals on endodontic treatment outcomes.
