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

objectivesThis study aimed to compare the efficacy of two non vital whitening techniques, In-office and Walking Bleach, using 35% hydrogen peroxide. The primary research question was to determine which technique achieves greater tooth color improvement. MATERIALS AND

methodsFifty non-vital anterior teeth with discoloration were randomly assigned to either the In-office (n = 25) or Walking Bleach (n = 25) groups. Tooth color was measured using a Vita EasyShade V

resultsBoth techniques improved tooth color, with final ΔE00 values of 10.08 for In-office and 8.12 for Walking Bleach. WID values were significantly higher in the In-office group, indicating greater whitening efficacy. Significant differences favoring the In-office method were seen after the first bleaching (p = 0.0337), and one-month follow-up (p = 0.0327).

conclusionsBoth the In-office and Walking Bleach techniques effectively improve the color of non-vital teeth, with the In-office method showing slight advantages at certain times. Clinicians can choose either technique based on safety, patient needs, and clinical context to achieve optimal results. CLINICAL RELEVANCE: This study provides evidence that both bleaching techniques are viable options for non-vital teeth whitening. The findings help clinicians choose the most appropriate technique based on biological safety and patient needs and desired outcomes, with the In-office technique being preferable for faster results.
