Dental caries prevalence in all school children in one of the grassroots areas in Southern China: a retrospective study.
Article in Frontiers in oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Background: The prevalence of dental caries among minors has always been a major issue globally, especially in economically underdeveloped regions. To investigate the prevalence of dental caries among all school children in Feng'an Town, which is one of the typical grassroots areas in southern China, providing reference basis for the development of oral health care for children in grassroots areas. Materials and methods: Data of a total of 2,834 children from all kindergartens, primary schools, and middle schools in Feng'an Town, one of the grassroots area in southern China was surveyed in this retrospective study. The prevalence of dental caries and the mean Decayed, Missing, and Filled Teeth (DMFT/dmft) scores (an index used to measure the severity of dental caries) for deciduous and permanent teeth were statistically analyzed and reported. A Chi-square test was used to assess the differences between the caries-free and have-caries group. The Mann-Whitney Results: In kindergartens, 79% of the 481 children had deciduous teeth caries, with a mean dmft score of 6.69 ± 5.31, and age was a significant factor influencing caries prevalence and mean dmft score ( Conclusion: The prevalence of dental caries among school children in grassroots areas in southern China is severe, necessitating attention and collaborative efforts from multiple sectors. Based on our findings, several policy measures could be considered to improve the oral health of children in grassroots areas. Firstly, monthly structured parental workshops in kindergartens led by certified dental hygienists. Secondly, implement school-based fluoride programs and atraumatic restorative treatments (ART). Thirdly, town government subsidize dental kits for low-income families. Fourthly, schools integrate daily supervised toothbrushing into schedules. Collaboratively, Guangdong Provincial Education Department allocate funds for annual dental check-ups and sealant programs. Finally, schools and health centers design flexible schedules with "dental slots" for emergency and preventive care.
