A global mapping of research on the relationship between oral health and nutritional status.
Article in BDJ open, 2026. 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
BACKGROUND/
objectiveOral health and nutritional status are closely interlinked through biological, functional, and behavioural pathways, yet the global research landscape connecting these domains has not previously been systematically mapped. This study aimed to provide a comprehensive bibliometric assessment of worldwide research linking oral health and nutritional status, identify influential publications, and analyze thematic developments over time. MATERIALS AND
methodsData were retrieved from the Science Citation Index Expanded (SCI-EXPANDED) within the Web of Science Core Collection. Publications from 1991-2024 were identified using a structured search strategy incorporating primary and extended terminology. Document characteristics, citation performance, authorship patterns, and publication indicators (TP, IP, CP, FP, RP, and SP) were analyzed alongside citation indicators (C
resultsA total of 10,074 publications were identified, including 8747 articles. Global research activity increased steadily, with citation maturity typically reached after 13 years. The USA, UK, Japan, and China led in publication output, while international collaboration was associated with higher citation impact. The ten most-cited articles reflected epidemiological surveillance, methodological standardization, global oral disease burden, and clinical nutrition guidelines. Keyword analysis revealed five overarching subjects: epidemiology, nutrition-related determinants of oral function and disease, clinical and quality-of-life outcomes, intervention strategies, and vulnerable populations.
conclusionsThis study provides the first global bibliometric overview of research linking oral health and nutritional status. Findings highlight an expanding, interdisciplinary field with growing methodological sophistication and public health relevance.
