Article in Journal of conservative dentistry and endodontics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: This study compared the effectiveness, color stability, and patient satisfaction of Opalescence Endo and 30% hydrogen peroxide (HP) with sodium perborate in internal (walking) bleaching of discolored, root canal-treated maxillary anteriors. Materials and Methods: A total of 122 discolored teeth were randomly allocated into two groups: Group 1: Opalescence Endo ( Statistical Analysis: Mann-Whitney Results: Significant differences were observed in the L* value after treatment (Group 1: 81.66 and Group 2: 83.52), total days taken for bleaching (Group 1: 16.76 days and Group 2: 21.80 days), and the first-time color change noted by the patient (Group 1: 1.95 days and Group 2: 3 days), favoring the Opalescence Endo. For severely discolored teeth ( Conclusion: Opalescence Endo demonstrated superior performance and faster bleaching compared to 30% HP with sodium perborate.
