Clinical Comparison of School-Based Dental Sealant Programme Among Different Caries-Risk School Children: A 5-Year Follow-Up Study.
Article in International journal of paediatric dentistry, 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
backgroundLimited evidence supports the sealant application for children.
aimTo assess the association between dental sealant and caries occurrence on first permanent molars among children with different caries risks after 5-year follow-up.
designThis ambispective (retrospective-prospective) cohort study retrieved data from dental sealant programmes conducted in 2019 and 2024 in Bangkok. Students who participated in the programme during first grade (P1) in 2019 and sixth grade (P6) in 2024 and had at least one sound first permanent molar at baseline were included and categorised based on the number of untreated carious teeth in P1: high-risk (> 2 teeth), moderate-risk (1-2 teeth) and low-risk (no carious teeth). Logistic regression analyses were used to compare caries occurrence between students with at least one sealed first permanent molar and those without for each caries risk group.
resultsSix-hundred-ninety-five students with 2198 sound first permanent molars were analysed. Sealants did not show a significant caries-preventive effect in low-and-moderate-caries-risk groups. The high-risk group, those with at least one sealed tooth, had a significantly lower risk of developing caries (adjusted OR = 0.48; 95% CI: 0.29-0.80; p = 0.005).
conclusionDental sealants are significantly associated with lower caries occurrence, particularly in high-risk children.
