Periodontal disease and neuroinflammation in multiple sclerosis: a systematic review of current evidence.
Review in Frontiers in dental medicine, 2026. 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: Multiple Sclerosis (MS) is a chronic, immune-mediated neurological disorder characterized by demyelination and neurodegeneration. Emerging evidence suggests a link between MS and Periodontal Diseases (PD) through shared immune-inflammatory pathways. This review assesses the association between periodontal diseases and multiple sclerosis, focusing on immune-inflammatory interactions and clinical correlations. Despite emerging evidence, the strength of association remains unclear due to methodological heterogeneity. Aim: To review and evaluate the literature on the epidemiological association between PD and MS in adults. Materials and methods: A systematic search was conducted in PubMed, Scopus, and Cochrane. Studies with full text articles that are available in English, without time restrictions, that assessed periodontitis, oral microbiome, and salivary biomarkers in relation to MS were included. Observational studies evaluating clinical, microbiological, or immunological associations were selected. Data extraction covered periodontal parameters, salivary biomarkers, periodontal pathogens and disease severity. The risk of bias was evaluated using Newcastle-Ottawa Scale. Results: The findings indicated that patients with MS had poorer periodontal health, when compared to healthy controls. Dysbiosis in the oral microbiome was observed, with a higher abundance of periodontal pathogens. Patients with MS exhibited elevated neutrophil-lymphocyte ratios and total oxidative stress, indicating a potential link between systemic inflammation and periodontal dysbiosis. While some studies established positive association between PD and MS, others highlighted the need for further investigation due to inconsistent findings in periodontal parameters between MS patients and controls. Conclusion: Despite methodological heterogeneity, the available limited evidence indicates the association between periodontitis and MS. This highlights the need for standardized periodontal assessments in research involving MS and suggests that periodontal care may hold potential as an adjunct in management of MS.
