Management of Discolored Endodontically Treated Maxillary Central Incisors With Nonsurgical Retreatment and Internal Bleaching: A Case Report.
Article in Cureus, 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
Tooth discoloration in endodontically treated anterior teeth represents a clinically significant problem, particularly in cases with high esthetic expectations. When pain, percussion sensitivity, or radiographic findings accompany such teeth, the existing endodontic status should be reassessed before esthetic treatment. This case report presents the clinical management of a 28-year-old patient who presented with pain, percussion sensitivity, and marked coronal discoloration in previously endodontically treated maxillary central incisors, teeth #11 and #21. After removal of the existing root canal filling materials, the root canals were reshaped, an irrigation protocol was performed, and calcium hydroxide was placed as an intracanal medicament. After resolution of the symptoms, the root canals were obturated with a bioceramic-based root canal sealer and gutta-percha. Following the placement of a cervical barrier, internal bleaching was performed. At the end of treatment, the patient's symptoms had resolved, and a marked improvement in anterior esthetics was observed. This case demonstrates that, in symptomatic and discolored endodontically treated anterior teeth, initial infection control followed by conservative esthetic rehabilitation with internal bleaching may represent a clinically appropriate approach.
