Trends in dental caries and related factors among second-grade students in Dongying District, 2018-2022.
Article in BMC oral health, 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
backgroundThe incidence of dental caries among children in Dongying City is very high. In 2018, the city launched a regional policy that provided free pit and fissure sealants and school-based oral health education. This study aims to assess the five-year impact of a regional public oral health policy.
methodsThis study adopted a census sampling method to include eligible research subjects. Through oral examinations and parent questionnaires, chi-square tests, variance analysis, and trend tests were used to evaluate the effectiveness of the intervention measures for second-grade students.
resultsThe survey results showed that the overall tooth decay rate decreased from 86.4% in 2018 to 84.6% in 2022, and the difference was at the borderline significance level (P = 0.05). Notably, the caries rate and Decayed, Missing due to caries, and Filled Teeth index (DMFT) for permanent teeth demonstrated a significant decline (P < 0.05), whereas those for deciduous teeth showed minimal changes. Although the filling rate for dental caries increased in 2022, it remained relatively low. The key performance indicators all showed significant trends (P < 0.05).
conclusionsThe oral health intervention measures implemented in Dongying City effectively reduced the level of permanent tooth caries among second-grade students. However, the improvement of deciduous tooth caries was not significant, and the filling rate remained low. It is necessary to strengthen the long-term oral health behavior cultivation of both families and schools, enhance the supervision of the intervention projects, and improve the treatment work in key areas to enhance the effect of caries prevention.
