Reinforcing bleached roots: A comparative study of intraorifice barriers.

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
Aim: The aim of this study was to assess the influence of three types of intraorifice barriers (IOBs) on the fracture toughness of root canal-treated teeth subjected to intracoronal bleaching. Materials and Methods: Endodontic therapy was performed on 60 extracted maxillary central incisors, which were subsequently randomized into four groups ( Statistical analysis: A statistical evaluation of the data was carried out with one-way analysis of variance and subsequent Results: All the IOB groups showed higher fracture toughness than the control group. Among the tested materials, TheraCal exhibited the highest reinforcement, followed by Ionoseal and GIC, with statistically significant differences ( Conclusion: Endodontically treated teeth subjected to intracoronal bleaching demonstrated greater fracture resistance when IOBs were applied. TheraCal proved to be the most effective material, highlighting its clinical relevance in preserving tooth integrity during bleaching procedures.
