Evaluating the Effectiveness of Bloom's Taxonomy‐Based Occupational Exposure Prevention in Oral Emergency Departments: A Quasi‐Experimental Study

OBJECTIVE: To evaluate a Bloom's Taxonomy-based occupational exposure (OE) prevention program's impact on dental trainees' competencies compared to conventional training, assessing knowledge, skills, satisfaction, and exposure rates to guide safety education improvements. METHODS: The non-randomised controlled quasi-experimental study was conducted from March to April 2025 in the oral emergency department of a tertiary dental hospital in Southwest China, involving 56 dental standardised training doctors (28 per group) allocated by training cohort. The intervention group (April 2025 cohort) received a structured Bloom's Taxonomy-based program featuring intensive first-day theory-practice sessions and daily 10-20 min skill reinforcement, while the control group (March 2025 cohort) underwent conventional training with one-time orientation and brief daily reminders. Outcome measures included post-intervention comparisons of theoretical knowledge, practical skills, satisfaction ratings, and occupational exposure incidence rates. RESULTS: Baseline characteristics showed no significant differences (age, gender, duration of standardised training, specialty, and work experience; all p > 0.05). The intervention group demonstrated significantly better performance in knowledge retention (p < 0.001), practical skills (p < 0.001), and satisfaction ratings (p < 0.001). While OE incidence was lower in the intervention group (3.6% vs. 10.7%), this difference did not reach statistical significance (p > 0.05). CONCLUSION: An educational intervention based on Bloom's Taxonomy plays an important role in enhancing the knowledge, practice and satisfaction of standardised dental trainees in OE prevention. Although the observed reduction in OE incidence was not statistically significant, it suggests clinical relevance and warrants further investigation.
