Inequalities in the demand for dental services in Brazil: associated factors in the 2023 National Oral Health Survey.
Article in Revista brasileira de epidemiologia = Brazilian journal of epidemiology, 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
objectiveTo analyze sociodemographic factors associated with the use of dental services in Brazil, based on data from the National Oral Health Survey - SB Brasil 2023.
methodsThis cross-sectional, population-based study used data from 40,489 individuals aged 18 years or older. The dependent variable was the use of dental services in the previous year. Analyses accounted for the complex sampling design, including weighting and design corrections. Descriptive and bivariate analyses (χ2 test) were conducted, followed by multiple logistic regression to estimate odds ratio (OR) and 95% confidence intervals (95%CI).
resultsApproximately 58.8% of respondents reported having used dental services in the previous year. A higher likelihood of use was associated with being female (OR=1.44; 95%CI 1.20-1.74), having higher educational attainment (complete higher education: OR=3.16; 95%CI 2.01-5.00), and higher income (>10 minimum wages: OR=2.79; 95%CI 1.63-4.78). Conversely, increasing age (OR=0.99; 95%CI 0.98-0.99) and residence in state capitals (OR=0.70; 95%CI 0.59-0.83) were associated with a lower likelihood of using dental services.
conclusionInequalities in the use of dental services persist in Brazil and are influenced by educational attainment, income, and vulnerability-related factors. These findings highlight the need for public policies aimed at reducing structural barriers and expanding equitable access to oral health care.
