Effects of vitamin B12 in culture medium for calcified nodule formation by rat dental pulp cells.

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/purpose: Tooth or bone regeneration requires large numbers of mesenchymal stem cells (MSCs). Although dental pulp is a suitable cell source, the number of MSCs present in this tissue is limited and they require a long period for regeneration. Therefore, the present study investigated vitamin B12 (Vb12) as an osteoinductive factor for MSCs obtained from dental pulp. Materials and methods: Dental pulp tissue was removed from the root canals of the extracted mandibular incisors of three 6-week-old male Fischer 344/N Slc rats using an endodontic file and whole cells were harvested. After the primary culture, cells were sub-cultured for calcified nodule formation in MEM containing dexamethasone (Dex), β-glycerophosphate (β-GP), vitamin C (Vc), and Vb12. Calcified nodules were confirmed under an inverted phase-contrast microscope. The alkaline phosphatase (ALP) activity of cells and quantity of Ca Results: Densely arranged calcified nodules were microscopically observed after the subculture of cells with Dex, β-GP, Vc, and Vb12. The ALP activity level was 0.077 ± 0.023 μmol/μg DNA in MEM supplemented with Vb12, which did not significantly differ from that without Vb12. A mass of calcium nodules formed in culture medium containing Dex, β-GP, Vc, and Vb12. The quantity of Ca Conclusion: Vb12 is effective for
