Video-Assisted Learning for Oral Health Knowledge in Children: A Pre-post Intervention Study.
Article in Cureus, 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
Introduction Tooth decay is a common childhood disease. There is growing recognition of the value of community-based, personalised, and digitally driven interventions in enhancing oral healthcare. Methodology One hundred and fifty-five students from two schools with the highest "decayed, missing, and filled teeth (DMFT)" indices in Lisbon were selected. The intervention consisted of a four-week program featuring educational videos on oral health (tooth structure, hygiene, diet, and diseases), with pre-, post-intervention, and three-month follow-up assessments. The sessions were facilitated by family medicine resident doctors, oral health hygienists, and teachers. Children who did not complete the program were excluded. Guardian-informed consent was obtained. The data was anonymised. Statistical analysis included repeated-measures analysis of variance (ANOVA) and McNemar tests. Results A hundred and eight children were included (mean age 9.24 ± 0.75 years, range 8 - 11). After the intervention, the proportions of children brushing two to three times/day and flossing daily increased (from 77.8% to 85.2% and from 42.6% to 49.1%, respectively). From baseline, the mean dental health knowledge score improved by 1.77 points after the intervention [9.47 to 11.24/13, 95% confidence interval (CI) 2.21 - 1.32, p < 0.01] and by 0.52 points at follow-up (9.47 to 9.99, 95%CI 0.95 - 0.08, p = 0.014). Conclusion This video-based intervention enhanced student engagement with oral health content while providing valuable insights into the effectiveness of digital education in promoting better oral health knowledge among children.
