The purpose of this study was to evaluate the effect of Dental Practicality Index (DPI) training using an online video on the treatment planning decisions and confidence level of dental undergraduates (DUs).
Ninety-four DUs were shown 15 clinical case scenarios and asked to decide on treatment plans based on 4 treatment options. The most appropriate treatment plan had been decided by a consensus panel of experienced dentists. DUs then underwent DPI training using an online video. In a post-DPI-training test, DUs were shown the same clinical case scenarios and asked to assign the best treatment option. After 6 weeks, DUs were retested to assess their knowledge retention. In all 3 tests, DUs completed the confidence level scale questionnaire. Data were analyzed using the related-samples Wilcoxon signed rank test and the independent-samples Mann-Whitney test with the level of significance set at < 0.05.
DPI training significantly improved the mean scores of the DUs from 7.53 in the pre-DPI-training test to 9.01 in the post-DPI-training test ( < 0.001). After 6 weeks, the mean scores decreased marginally to 8.87 in the retention test ( = 0.563). DPI training increased their confidence level from 5.68 pre-DPI training to 7.09 post-DPI training.
Training DUs using DPI with an online video improved their decision-making and confidence level in treatment planning.
本研究旨在评估使用在线视频进行牙科实用性指数（DPI）培训对牙科本科生（DUs）治疗计划决策和信心水平的影响。
向94名牙科本科生展示15个临床病例场景，并要求他们根据4种治疗方案决定治疗计划。最合适的治疗方案由经验丰富的牙医组成的共识小组确定。然后，牙科本科生使用在线视频接受DPI培训。在DPI培训后的测试中，向牙科本科生展示相同的临床病例场景，并要求他们选择最佳治疗方案。6周后，对牙科本科生进行重新测试，以评估他们的知识保留情况。在所有3次测试中，牙科本科生都完成了信心水平量表问卷。使用相关样本Wilcoxon符号秩检验和独立样本Mann-Whitney检验对数据进行分析，显著性水平设定为<0.05。
DPI培训显著提高了牙科本科生的平均分数，从DPI培训前测试中的7.53分提高到DPI培训后测试中的9.01分（<0.001）。6周后，在保留测试中平均分数略有下降，降至8.87分（=0.563）。DPI培训将他们的信心水平从DPI培训前的5.68提高到DPI培训后的7.09。
使用DPI和在线视频对牙科本科生进行培训可提高他们在治疗计划中的决策能力和信心水平。
