Evaluation of microleakage across different post-core systems in the endodontic-periodontal interface.
Article in Bioinformation, 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
The effect of different post and core systems on microleakage at the endodontic-periodontal interface (EPI) remains unclear, despite its potential impact on secondary endodontic and periodontal complications. Hence, 90 extracted human single-rooted premolars were randomly assigned to three groups (n=30): Group FRC (FRC post + composite core), Group CG (Cast gold post-core) and Group TI (Titanium post + composite core). Following standardized endodontic treatment, post spaces were prepared and posts were cemented using dual-cure resin cement. Cores were built accordingly. Teeth were subjected to thermocycling (10,000 cycles, 5°C-55°C) and cyclic loading (100,000 cycles, 50N). Microleakage at the EPI was assessed using a fluid filtration method under constant pressure (20 kPa) for 10 minutes, quantifying the fluid volume (µL) traversing the interface.
