Oral health status and its relation to frailty in older adults: a cross-sectional study.
Article in BMC geriatrics, 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
backgroundGiven the growing burden of population aging and the emerging evidence linking oral health to functional decline, further investigation in diverse settings is warranted. In this study, we aimed to investigate the association between oral health status and frailty among older adults in Indonesia.
methodsA cross-sectional study was conducted among 405 community-dwelling older adults aged 60 years and older residing in five sub-districts in Sleman, Yogyakarta, Indonesia, using a multistage cluster random sampling method. Frailty was assessed using the frailty phenotypic criteria and categorized as frail (≥ 3), pre-frail (1–2), or robust (none). Oral health parameters, including the number of functional tooth units (FTUs), dental caries, dysphagia (15-item scale), xerostomia (five-item Summated Xerostomia Inventory-Indonesian version), and oral health-related behaviors, were examined as independent variables. Multinomial and binary logistic regression analyses were conducted with frailty as the outcome variable, adjusting for sociodemographic characteristics, nutritional status, smoking behavior, chronic diseases, and number of medications.
resultsAmong the 405 participants, 16% were classified as frail and 75% as pre-frail. After adjusting for potential confounders, a greater number of FTUs were associated with lower odds of being frail and pre-frail. In contrast, a lower number of functional tooth units was associated with higher odds of exhaustion and weakness. Dysphagia was associated with higher levels of exhaustion, and xerostomia showed a similar pattern.
conclusionPoorer oral health, particularly a lower number of functional tooth units, was associated with greater frailty among older adults. Dysphagia and xerostomia were associated with exhaustion. These findings highlight the relevance of maintaining oral function to promote healthy aging.
