Impact of educational intervention on dental students' competence in managing injuries caused by sharp objects: a quasi-experimental study.

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
introductionSharp object injuries (SOI) pose significant risks to dental healthcare workers. This study evaluated the impact of an educational intervention on dental students' knowledge, attitudes, and practice habits regarding SOI management.
methodsA quasi-experimental before-after study was conducted among 87 dental students (59.8% female, 40.2% male; mean age: 23.45 years) in clinical years (DDS 2022-2025) at Qazvin University of Medical Sciences, Iran. Participants completed a validated 34-item questionnaire (10 knowledge, 7 attitude, 17 practice questions) before and after watching a 3-minute 36-second animated video on SOI management and post-exposure prophylaxis (PEP). Data were analyzed using SPSS 26 with chi-square, ANOVA, and Bonferroni correction (p < 0.0031).
resultsThis study revealed significant differences in immediate post-injury performance knowledge (P = 0.001), PEP awareness (P = 0.025), and needle-capping (P = 0.001). However, there was no statistically significant difference in the extent of injury with sharp objects based on sex or age. There was a significant relationship between students' year of university entry and the extent of injury with a sharp object (P = 0.025). Most students (67.8%) did not know how to function correctly after a sharp object injury, and the highest number of sharp object injuries occurred in the 7th semester. Over 60% of injuries went unreported, primarily due to perceived insignificance (44.1%).
conclusionsStructured educational interventions, particularly visual aids, enhance SOI management knowledge. However, long-term behavioral changes and reporting compliance require further investigation. Integrating SOI training into dental curricula and fostering a culture of incident reporting are critical to mitigating risks.
