1 · What the graph read from it

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.

2 · The registry

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

Objective: To evaluate and compare the shear bond strength (SBS) of three composite resins, Z250 (3M), Transbond XT (3M), and Brace Paste (AO), used for orthodontic bracket bonding on human enamel and ceramic surfaces, after undergoing accelerated aging. Materials and Methods: An in vitro experimental design was conducted using 30 enamel specimens (human premolars) and 30 ceramic specimens (Brava Block, FGM), divided into three subgroups per substrate ( Results: Transbond XT exhibited the highest mean SBS on ceramic surfaces (10.4 ± 5.2 MPa), while Brace Paste showed the highest SBS on enamel (7.3 ± 2.4 MPa). However, no statistically significant differences were observed among the composite resins in either substrate ( Conclusion: Although numerical differences were found, all three composite resins demonstrated comparable performance. When appropriate surface conditioning protocols are applied, any of the tested materials can be considered reliable for bracket bonding to both enamel and ceramic substrates. Further in vivo studies are recommended to validate long-term durability.
