Association between micronutrient intake and periodontal health: a cross-sectional analysis of the Rafsanjan cohort study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundPrevious studies have suggested that micronutrient deficiencies may play a role in developing periodontal diseases. However, the evidence on the association between micronutrient intake and periodontal diseases is limited and conflicting. We aim to investigate the association between dietary micronutrients and periodontal disease among the adult population of the Oral Health Branch of the Rafsanjan Cohort Study.
methodsThis cross-sectional study analyzed 3013 participants (aged 35-70) from the Rafsanjan Cohort Study. Dietary intake was assessed using a validated food frequency questionnaire. Periodontal health indices (bleeding on probing, clinical attachment loss, Periodontal probing depth, dental calculus) were evaluated, and sociodemographic, lifestyle, and medical data were collected. Logistic regression models assessed associations, adjusting for potential confounders.
resultsAmong 3013 participants (mean age: 48.62 ± 8.89 years; 62.99% male), higher dietary intake of alpha-carotene (OR: 0.77, 95% CI: 0.63-0.94), beta-cryptoxanthin (OR: 0.80, 95% CI: 0.65-0.99), fluoride, and vitamin A significantly reduced periodontal pockets and bleeding on probing. Conversely, a higher intake of vitamin K and sodium was associated with increased dental calculus prevalence (p < 0.05).
conclusionsThis study found significant links between sociodemographic factors, habits and diet with periodontal health. Increased alpha-carotene, beta-cryptoxanthin, and fluoride intake reduced periodontal pockets and bleeding, while sodium and vitamin K intake were associated with increased calculus formation.
