Effects of CEM cement and emdogain on proliferation and differentiation of human stem cells from the apical papilla: a comparative in vitro study.
Article in Biotechnology letters, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
objectivesThis study compared the effects of calcium-enriched mixture (CEM) cement, Emdogain (EMD), and their combination (CEM/Emdogain) on the differentiation and proliferation of stem cells from the apical papilla (SCAPs).
methodsIn this in vitro, experimental study, SCAPs were isolated from two sound immature impacted third molars and cultured. After ensuring their stemness by detecting cell surface markers they were exposed to CEM cement, Emdogain, and CEM cement coated with Emdogain for 24 and 72 h. The control cells did not undergo any intervention. Cell viability [by methyl thiazolyl tetrazolium (MTT) assay], expression of odontogenic differentiation genes [by quantitative reverse-transcription polymerase chain reaction (qRT-PCR)], and alkaline phosphatase (ALP) activity (by ALP staining kit) were evaluated. Data were analyzed by one-way ANOVA, t-test, and Mann-Whitney test (α = 0.05).
resultsCell viability in the CEM cement and CEM/Emdogain groups decreased compared with the control group at 72 h (P < 0.05). Expression of dentin sialophosphoprotein (DSPP), dentin matrix protein 1 (DMP1), bone sialoprotein (BSP) genes, and ALP activity significantly increased in all three experimental groups compared with the control group at both 24 and 72 h. This increase was substantially more significant in CEM/Emdogain group (P > 0.05). The number of mineralized nodules significantly increased in all groups at 72 h, with a higher rate in the CEM/Emdogain group.
conclusionAll biomaterials increased the differentiation of SCAPs, expression of odontogenic differentiation genes, and ALP activity, but CEM/Emdogain was considerably more effective for this purpose.
