Salivary and GCF Vitamin C Levels: Implications for Local and Systemic Periodontal Defense.
Article in International journal of dentistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Periodontitis is a chronic inflammatory condition influenced by oxidative stress, which contributes to tissue destruction. Vitamin C, a key antioxidant, is essential for maintaining periodontal health through its role in collagen synthesis and free radical scavenging. Objective: This study aimed to assess vitamin C levels in saliva and gingival crevicular fluid (GCF) across different stages of periodontitis and explore their potential as biomarkers of disease progression. Methods: A cross-sectional study was conducted involving 43 participants categorized into healthy, mild, moderate, and severe periodontitis groups according to the 2017 classification. Saliva and GCF samples were collected and analyzed for vitamin C using validated biochemical methods. Statistical analysis included Kruskal-Wallis tests and pairwise comparisons. Results: Salivary vitamin C levels were significantly higher in healthy individuals and progressively decreased with increasing disease severity. GCF vitamin C concentrations were consistently higher than in saliva across all groups, with elevated levels in both healthy and severe periodontitis participants. However, intergroup differences in GCF levels were not statistically significant. Conclusion: The study reveals distinct profiles of vitamin C in saliva and GCF, highlighting its local and systemic antioxidant roles. These findings suggest that vitamin C may serve as a useful biomarker in periodontal disease assessment.
