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

backgroundAs clear aligner technology (CAT) gains prominence, the performance of composite attachments - critical devices for optimizing aligner retention and tooth movement control - require systematic evaluation. This study assesses three light-cured composites (Filtek™ Z250 XT, Z350 XT, and P60; 3 M ESPE) regarding color stability, shear bond strength (SBS), and durability to establish evidence-based selection criteria.

methodsAttachments were bonded to mandibular premolars, simulating the clinical process, and materials were tested for color changes (after immersion in coffee, cola, or iced tea), SBS, and durability (wear volume, surface roughness, morphology, post-aging SBS). The data obtained from the study were statistically evaluated via the Shapiro-Wilk test, the Levene test, t-tests, one-way analysis of variance and chi-square test. A p-value < 0.05 was considered statistically significant.

resultsZ250 showed significantly higher coffee - induced discoloration than Z350 (p < 0.05) and P60 (p < 0.01), exceeding clinical acceptability (ΔE

conclusionsZ250 underperformed in color stability, SBS, and durability versus Z350/P60, though demonstrated cost-effectiveness. Z350 offers outstanding color durability and higher SBS but risks enamel damage from interfacial delamination. P60 excels with color stability, acceptable adhesive remnants, and exceptional wear resistance, serving diverse clinical needs. Clinical decisions could prioritize P60 for function-aesthetic balance, with targeted Z350/Z250 use in special scenarios.
