Convenience sampling of primary school students in Tianjin to evaluate the effectiveness of mobile-based virtual reality experimental learning in oral health education.
Article in BMC oral health, 2025. 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
backgroundOral health education provides schoolchildren with correct information about health and oral health care techniques. Traditional oral health education has poor knowledge transmission effect. Virtual reality (VR) currently has extensive applications and excellent results in medical education and technical learning. However, its application in oral health education for primary school students has not yet been known.
methodsA convenience sampling approach was employed to recruit 1,416 children in grades 3-5 from 16 districts of Tianjin City who had previously received traditional oral health education. One week prior to the intervention, parents received a quick response code to access the VR experience and were instructed to guide their children through the smartphone-based learning module. Then, medical staff administered questionnaires to the students in the classroom. VR efficacy was assessed by comparing oral health knowledge, attitudes, and technology acceptance between students exposed to VR and controls. Data were analyzed using Kruskal-Wallis H-tests and Mann-Whitney U-tests, and multiple linear regression analysis was employed to elucidate the pivotal factors influencing the efficacy of the oral VR experience.
resultChildren in grades 3-5 in Tianjin exhibited high receptivity to mobile-based VR technology, with a perceived ease of use of 9.03 ± 1.36 and a perceived usefulness of 9.40 ± 0.98. Among the students who experienced oral VR, 398 individuals (75%) reported a significant improvement in their attitudes towards oral health care, while 120 (22.6%) perceived a more substantial improvement. Students who experienced oral VR demonstrates a significant improvement in oral health knowledge (experimental group: 13.00(12.00,13.00) vs. control group: 10.00(8.00,12.00), p < 0.001). Schoolchildren in grade 4, with high father educational level, good brushing habits, and prior VR experience, achieved higher oral knowledge scores after the VR experience, with statistically significant differences observed.
conclusionWe present the first application of mobile virtual reality for oral health education in primary schools. Our study demonstrates high student acceptance of VR technology in Tianjin, China, alongside significant improvements in oral health knowledge and attitudes. Given its efficacy, accessibility, and visualization capabilities, mobile VR represents a promising tool for scalable oral health education.
