Bleaching techniques in primary teeth: a systematic review.
Synthesis in Evidence-based dentistry, 2024. 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
objectiveDiscolouration of primary teeth, often attributed to trauma and pulpal infection, is a prevalent concern that can significantly impact the esthetics and self-esteem of children. To address this issue, bleaching techniques have emerged as a viable treatment option. This systematic review aims to provide a comprehensive summary of the effectiveness of bleaching agents in managing discoloured primary teeth.
methodsTwo reviewers independently conducted an electronic database search using PubMed, EMBASE, LILACS, CINAHL via EBSCO, Scopus, and Web of Science until September 26,2023. In vitro studies and case reports that assessed the quantifiable success were included. The present review utilized Distiller SR software for data extraction. The protocol of this study was registered in PROSPERO (International Prospective Register of Systematic Reviews) (CRD42022329831). The quality of studies was analysed with Cochrane tool and the JBI checklist.
resultsThe search retrieved 1845 references of which 14 studies were included for qualitative analysis. There were 8 in vitro studies and 6 case reports included in this systematic review. There were 299 teeth samples in the in vitro studies and 18 teeth were assessed in the case reports. All the 18 teeth (6 case reports) showed considerable shade improvement within 7-14 days. However, only 3 teeth were followed up for a period of 12-24 months. Substantial shade improvement was also observed in samples in the in vitro studies.
conclusionThis systematic review has comprehensively examined the various bleaching agents and methods for the management of discoloured primary teeth. However, it is crucial to recognize that the available evidence is from case reports and is insufficient to make a clinical recommendation.
