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
backgroundRoot resorption is a complex problem in endodontic treatment that considerably affects the structural integrity of teeth. This study aims to assess the biomechanical efficacy of various restorative materials and approaches in treating external root resorption, emphasizing their capacity to improve stress resistance and guarantee long-term success.
methodsThis research employed finite element analysis (FEA) to assess stress distribution in mandibular premolars with external root resorption. Eight models, demonstrating apical and mid-level resorption, were repaired using mineral trioxide aggregate (MTA), Biodentine, or a mixture of these materials with gutta-percha. In order to evaluate each technique's biomechanical performance, the models were exposed to both vertical and oblique stresses.
resultsThe findings demonstrated that complete canal obturation with Biodentine or MTA greatly lowered stress levels, with Biodentine exhibiting a marginal advantage. The hybrid approach utilizing gutta-percha produced elevated stress concentrations, especially under oblique loading conditions.
conclusionMTA and Biodentine are effective in enhancing resistance to biomechanical forces in teeth with external resorption. However, the combination of gutta-percha with these materials reduces resistance, especially under oblique forces. These findings highlight the importance of material selection in restoring resorbed teeth and improving clinical outcomes.
