Association Between Health Literacy, Oral Health Literacy, and Periodontal Disease.
Article in International dental journal, 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
introductionInadequate health literacy and oral health literacy may adversely impact an individual's capacity for disease management, including the management of periodontitis.
aimThis study investigated the association between health literacy (HL), oral health literacy (OHL), and periodontal disease severity.
methodsA cross-sectional analytical study was conducted in Chiang Mai Province. Demographic data, oral health behaviours, and periodontal status were collected. Periodontal disease severity was classified according to the 2018 American Academy of Periodontology/European Federation of Periodontology (AAP/EFP 2018) criteria. Health literacy was assessed using the General Health Literacy Scale for Thai people (GHLS), and OHL was measured using the Thai version of the Rapid Estimate of Adult Literacy in Dentistry (ThREALD-30). Associations were analysed using ordinal logistic regression, adjusting for potential confounders.
resultsA total of 247 participants were included (mean age: 45.42 ± 15.92 years). The mean HL and OHL scores were 180.63 ± 24.79 and 27.50 ± 2.46, respectively. Most participants (58.70%) were diagnosed with stage III or IV periodontitis. No significant association was observed between the HL scores and periodontal disease severity. In contrast, OHL scores were significantly associated with periodontal disease severity (Crude OR 0.69; 95% CI: 0.58-0.81, p < .001). After adjusting for potential confounders, OHL remained significantly associated with periodontal disease severity (adjusted OR 0.82; 95% CI: 0.68-0.99, p = .039).
conclusionsOral health literacy was significantly associated with periodontal disease severity, whereas HL showed no such association. CLINICAL RELEVANCE: These findings emphasize the critical role of evaluating and enhancing OHL in improving periodontal health outcomes at the population level.
