Sharp 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.
A 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).
This 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%).
Structured 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.
锐器伤对牙科医护人员构成重大风险。本研究评估了一项教育干预措施对牙科学生在锐器伤管理方面的知识、态度和实践习惯的影响。
在伊朗加兹温医科大学临床阶段（2022 - 2025年牙医学士课程）的87名牙科学生（59.8%为女性，40.2%为男性；平均年龄：23.45岁）中进行了一项前后对照的准实验研究。参与者在观看一段关于锐器伤管理和暴露后预防（PEP）的3分36秒动画视频前后，完成一份经过验证的34项问卷（10项知识、7项态度、17项实践问题）。使用SPSS 26软件进行数据分析，采用卡方检验、方差分析和Bonferroni校正（p < 0.0031）。
本研究显示，受伤后即刻处理知识（P = 0.001）、PEP知晓率（P = 0.025）和针头盖帽操作（P = 0.001）存在显著差异。然而，基于性别或年龄的锐器伤程度在统计学上没有显著差异。学生入学年份与锐器伤程度之间存在显著关系（P = 0.025）。大多数学生（67.8%）不知道锐器伤后如何正确处理，锐器伤发生最多的是在第7学期。超过60%的损伤未报告，主要原因是认为损伤不严重（44.1%）。
结构化的教育干预措施，特别是视觉辅助工具，可增强锐器伤管理知识。然而，长期行为改变和报告依从性仍需进一步研究。将锐器伤培训纳入牙科课程并培养事件报告文化对于降低风险至关重要。
