Student-generated multiple-choice questions enhance deeper learning in dental materials education: a randomized crossover trial.
Trial report in BMC medical education, 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
backgroundDental materials education poses unique challenges due to the complex integration of scientific principles with clinical applications. Traditional teaching methods often fail to promote deep conceptual understanding. This study investigated whether the process of generating multiple-choice questions (MCQs) by students could enhance deeper learning, knowledge application, and critical thinking in dental materials education.
methodsA prospective, randomized crossover study was conducted among second-year dental students (n = 64) at the Nair Hospital Dental College, Mumbai. The study comprised of two phases examining different topics of similar difficulty (dental restorative composites and glass ionomer cements). Following the didactic lectures, all students completed the pre-tests and were randomly allocated to the intervention (MCQ generation activity with faculty-moderated discussion) or control group (additional study time). After a washout period of two weeks, the groups were crossed over. The primary outcome was the difference in post-test performance between the groups. The secondary outcomes included performance across cognitive domains and student feedback. Data were analyzed using paired and independent t-tests, with mixed-effects models for crossover analysis.
resultsSixty-two students completed both study phases. The intervention group demonstrated significantly higher post-test scores compared to controls in both phases: Phase 1 (approximately 76.8% ± 7.6% vs. 65.3% ± 8.9%, P < 0.001, Cohen’s d = 1.38) and Phase 2 (approximately 74.5% ± 8.1% vs. 63.9% ± 9.4%, P < 0.001, Cohen’s d = 1.22). The largest improvements were observed in application/analysis questions (Cohen’s d = 1.89 and 1.57 for phases 1 and 2, respectively). Mixed-effects analysis confirmed significant intervention effects (F = 42.36, P < 0.001) without period or carryover effects. Student feedback was positive, with approximately 87.1% of the students reporting enhanced understanding.
conclusionsStudent-generated MCQs offer an effective and scalable strategy for fostering deeper learning in dental material education. This process encourages active engagement, supports higher-order cognitive development, and can be seamlessly integrated into existing curricula with minimal resource investment. This approach can potentially enhance both academic outcomes and clinical readiness in dental education.
