Efficacy of Different Concentrations of Melatonin on Cultured Human Periodontal Ligament Stem Cells.
Article in Medical science monitor basic research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BACKGROUND Due to their good differentiation abilities, human periodontal ligament stem cells (hPDLSCs) and tissue engineering treatment modalities are used to treat bone defects due to periodontitis. This in-vitro study aimed to determine the effects of different melatonin concentrations on the viability of cultured periodontal ligament stem cells. MATERIAL AND METHODS Cultured hPLDSCs were treated with different melatonin concentrations. The study groups were divided into 9 concentration-based groups: Group 1, untreated hPDLSCs; Group 2, hPDLSCs exposed to physiological doses of melatonin (1 μM); Group 3, hPDLSCs exposed to 10 μM melatonin; Group 4, hPDLSCs exposed to 20 μM melatonin; Group 5, hPDLSCs exposed to 30 μM melatonin; Group 6, hPDLSCs exposed to 40 μM melatonin; Group 7, hPDLSCs exposed to 50 μM melatonin; Group 8, hPDLSCs exposed to 100 μM melatonin; Group 9, hPDLSCs exposed to 150 μM melatonin. Cell viability was evaluated at 14 and 21 days using the AlamarBlue (AB) Cell Viability Assay, a toxicity assay. RESULTS Melatonin had a positive effect on hPDLSC viability in all test groups. A general pattern of decreasing cell viability with increasing melatonin concentrations was observed, with Groups 8 and 9 showing the lowest viability. An abrupt pattern was detected in Groups 4 and 7, where a sudden, significant increase in cell viability was observed, in contrast with the general observed pattern. CONCLUSIONS In conclusion, the hPDLSCs remained viable when exposed to the melatonin doses used, under osteogenic media, except for the 100µM and 150 µM melatonin groups. Therefore, further studies are required with hPDLSCs exposed to different concentrations of melatonin.
