Effects of systemically administered cholecalciferal and vitamin B complex on mental nerve injury in rats.
Article in Scientific reports, 2025. 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
This study aimed to evaluate the effects of systemic cholecalciferol (vitamin D3) and vitamin B complex (B1, B6, B12) on crush-injured mental nerve in rats using histopathological and immunohistochemical analyses to assess nerve degeneration and regeneration. Thirty-two Wistar Albino rats were subjected to standardized mental nerve crush injury using a Yasargil aneurysm clip and divided into four groups: Control /Sham (Group 1), B vitamin (intraperitoneal) (Group2), D vitamin (oral) (Group 3), and combined (B + D) (Group 4). After 4 weeks, nerve samples were excised for histopathological evaluation (ghost cell and hyperchromatic nuclei counts) and immunohistochemical analysis (S100β and BIII tubulin scores). Data were analyzed using Generalized Linear Models with Bonferroni post-hoc tests. Treatment groups showed significantly lower ghost cell counts (e.g., Group 3: 15.33 ± 3.50 vs. Control: 53.67 ± 9.63, p < 0.001) and hyperchromatic nuclei counts (e.g., Group 4: 28.00 ± 5.40 vs. Control: 34.33 ± 4.37, p = 0.004) compared to controls. Immunohistochemically, Group 4 exhibited significantly higher ßIII tubulin scores (3.17 ± 0.39 vs. Control: 1.75 ± 0.46, p < 0.001), indicating enhanced axonal regeneration, while S100β scores were similar between Group 3 and 4 (1.83 ± 0.39, p = 1.000). After a 4-week healing period, cholecalciferol and vitamin B complex, particularly in combination, significantly reduced axonal degeneration and promoted early nerve regeneration in a rat mental nerve injury model. These findings suggest potential as adjunctive therapies for nerve recovery in oral and maxillofacial surgery, pending clinical validation.
