Global Burden of Oral Disorders in Adults Aged ≥65, 1990 to 2021: A Systematic Analysis of Global Burden of Disease Study 2021.
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
aimThis study aimed to examine the global burden, trends, and socioeconomic inequalities associated with oral disorders in adults aged 65 years and older from 1990 to 2021, and to project future trends to inform targeted public health strategies.
methodsUsing data from the Global Burden of Disease Study 2021, we examined age-standardized DALY rates for oral conditions. Analytical methods included Joinpoint regression (for trend analysis), the slope index of inequality and concentration index(for inequality assessment), frontier analysis (for efficiency assessment), and autoregressive integrated moving average modelling (to project trends through 2035).
conclusionAbsolute case counts for all oral diseases increased significantly (by 112%-142%) from 1990 to 2021. Although age-standardized disability rates declined for edentulism, dental caries, and other oral disorders, they remained stagnant for periodontal diseases and lip/oral cavity cancer. Socioeconomic disparities persisted or even widened, with disease-specific patterns. Projections to 2035 indicate a growing burden among older populations, highlighting an urgent need for equitable and targeted public health interventions.
