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

objectivesThe aim of this study was to investigate the effects of non-vital bleaching agents and resin composite types on the color stability, translucency parameter, and whiteness index of non-vital teeth at different time intervals. MATERIALS AND

methods135 extracted single-rooted maxillary central incisors were used. The teeth were stained with coffee, baseline color values were measured, and root canal treatment was completed. The samples were randomly divided into three main groups: two bleaching agent groups (Opalescence and Whiteness-Super-Endo)and a control group. Each group was randomly divided into three subgroups (n = 15). The subgroups were restored with different resin composites (Filtek-Z250, FiltekBulk-Fill, Omnichroma) and subjected to thermocycling, and color measurements were repeated. The color differences (ΔE

resultsBleaching treatments caused color changes exceeding acceptable thresholds in all groups. Regarding color change and the translucency values, there was no significant difference between the two bleaching agents; however, both agents demonstrated significantly higher effectiveness compared with the control group (p < 0.001). In terms of WI

conclusionBleaching treatments caused color changes exceeding acceptable thresholds in all groups. An increase in RTP CLINICAL RELEVANCE: This study enhances the understanding of how different non-vital bleaching agents and resin composites affect the long-term optical properties of endodontically treated teeth, providing valuable insights for optimal material selection in esthetic restorations.
