Effective management of medical waste management (MWM) in dental clinics is essential for occupational safety and environmental sustainability, yet standardized training programs tailored to professional roles remain understudied. This quasi-experimental pre-post study evaluated a novel role-specific training intervention's impact on knowledge, attitudes, and practices (KAP) among 187 dental professionals (80 dentists, 60 nurses, 47 dental students) at a dental hospital. Participants underwent training aligned with WHO guidelines and China's Medical Waste Management Regulations (Order No. 380), with KAP assessed via validated questionnaires (Cronbach's α = 0.85) pre- and post-training. Baseline knowledge varied significantly by role (dentists: 65.2% vs. students: 52.0%, p < 0.01). Post-training analyses revealed substantial improvements: knowledge scores increased from 60.2 to 91.2% (Δ + 30.7%, p < 0.001, Cohen's d = 1.81), attitudes improved by 17.3 points (d = 1.66), and practices by 22.0 points (d = 1.84). Two-way repeated-measures ANOVA demonstrated significant time × group interactions for knowledge (F(2,184) = 4.9, p = 0.03, η=0.05) and practices (F(2,184) = 5.7, p = 0.02, η=0.06), with dental students showing maximal gains (knowledge Δ + 25.0%, p = 0.002 vs. dentists; practices Δ + 24.0%, p = 0.004). Nurses achieved marked practice compliance improvements (Δ + 20.0%), surpassing prior reports in general healthcare settings. Demographic factors (gender/age) did not moderate outcomes. These findings underscore the efficacy of role-specific education in bridging competency gaps, particularly for early-career professionals. The large effect sizes (d = 1.3-2.3) and 30.7% absolute knowledge gain highlight scalable strategies to align dental training with global MWM standards. Integration of such programs into dental curricula and mandating of periodic refresher courses are advocated to sustain compliance and mitigate public health risks.
牙科诊所医疗废物管理（MWM）的有效管理对于职业安全和环境可持续性至关重要，但针对专业角色的标准化培训项目仍未得到充分研究。这项准实验性前后对照研究评估了一种新颖的针对特定角色的培训干预措施对一家牙科医院187名牙科专业人员（80名牙医、60名护士、47名牙科学生）的知识、态度和实践（KAP）的影响。参与者接受了符合世界卫生组织指南和中国《医疗废物管理条例》（第380号令）的培训，并通过经过验证的问卷（Cronbach's α = 0.85）在培训前后评估KAP。基线知识因角色而异（牙医：65.2% 对学生：52.0%，p < 0.01）。培训后分析显示有显著改善：知识得分从60.2% 提高到91.2%（Δ + 30.7%，p < 0.001，Cohen's d = 1.81），态度提高了17.3分（d = 1.66），实践提高了22.0分（d = 1.84）。双向重复测量方差分析显示知识（F(2,184) = 4.9，p = 0.03，η=0.05）和实践（F(2,184) = 5.7，p = 0.02，η=0.06）存在显著的时间×组交互作用，牙科学生的收获最大（知识Δ + 25.0%，p = 0.002对比牙医；实践Δ + 24.0%，p = 0.004）。护士在实践合规方面有显著改善（Δ + 20.0%），超过了一般医疗环境中的先前报告。人口统计学因素（性别/年龄）并未调节结果。这些发现强调了针对特定角色的教育在弥合能力差距方面的有效性，特别是对于早期职业专业人员。较大的效应量（d = 1.3 - 2.3）和30.7%的绝对知识增益突出了使牙科培训与全球MWM标准保持一致的可扩展策略。建议将此类项目纳入牙科课程并强制要求定期进修课程，以维持合规并降低公共卫生风险。
