255-nm Light-emitting Diode Kills Enterococcus faecalis and Induces the Production of Cellular Biomarkers in Human Embryonic Palatal Mesenchyme Cells and Gingival Fibroblasts.
Article in Journal of endodontics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
introductionThe successful treatment of infected or inflamed endodontic tissues requires chemomechanical debridement of the canal spaces and proper sealing of the coronal and apical canal openings. Only a few methods are available to further disinfect areas or initiate regeneration of local tissues. In this study, we assessed the ability of 255-nm and 405-nm light-emitting diode (LED) treatment to kill planktonic cultures of Enterococcus faecalis and induce the production of cellular biomarkers related to endodontic tissue regeneration.
methodsWe determined the antimicrobial effects of 255-nm and 405-nm LED treatment on E. faecalis and the effects of 255-nm and 405-nm LED treatment on the production of osteoinductive, angiogenic, proliferative, and proinflammatory biomarkers from human embryonic palatal mesenchyme (HEPM) cells and gingival fibroblasts.
resultsWe showed that 255-nm LED but not 405-nm LED treatment killed E. faecalis; the 255-nm LED and sodium hypochlorite more efficiently killed E. faecalis; neither 255-nm nor 405-nm LED treatment affected the viability of HEPM cells and gingival fibroblasts; and 255-nm LED treatment, alone or in combination with 405-nm LED treatment, of HEPM cells and gingival fibroblasts induced the production of biomarkers related to endodontic tissue regeneration.
conclusionsThe results of this study suggest a new treatment modality using short periods of 255-nm LED treatment as an adjunct to chemomechanical debridement for the disinfection of inflamed sites and the production of biomarkers related to endodontic tissue regeneration.
