Dental treatment for children requires not only technical skills, but also the knowledge and confidence to provide behaviour management to support children of differing ages and stages of development. It is not surprising then that dental students find treating children especially stressful. Paediatric dentistry training is therefore a vital element of the undergraduate dental curriculum.
Eighty-six fourth-year undergraduate dental students received standard lectures and seminars about behaviour management techniques for children having local anaesthetic. The students were then randomly divided into groups using cluster randomisation. The intervention group received an intervention-based around video clips (VCs) demonstrating behaviour management techniques (BMTs) for children receiving local anaesthetic The intervention and control groups completed self-administered questionnaires to determine their level of confidence in managing local anaesthetic for children.
There was a statistically significant difference in the level of confidence between the groups immediately after the teaching intervention (P=.003) and at 4 months (P=.001) in favour of the video group.
Previous studies on the use of video as a teaching aid have reported favourable results in terms of both student attitudes and learning outcomes. The results from this study confirm the benefits of this style of teaching paediatric behaviour skills in the undergraduate dental curriculum, and the benefits were maintained at 4 months.
This study has demonstrated that VCs as an additional teaching aid are an effective method in improving students' confidence for BMTs when delivering local anaesthetic.
儿童牙科治疗不仅需要技术技能，还需要具备知识和信心，以便提供行为管理，来支持不同年龄和发育阶段的儿童。因此，牙科学生觉得治疗儿童特别有压力也就不足为奇了。所以，儿科牙科培训是本科牙科课程的重要组成部分。
八十六名牙科专业四年级本科生接受了关于儿童局部麻醉行为管理技术的标准讲座和研讨会。然后使用整群随机化方法将学生随机分组。干预组观看了一系列围绕为接受局部麻醉的儿童展示行为管理技术（BMT）的视频片段。干预组和对照组完成了自我管理问卷，以确定他们在为儿童进行局部麻醉管理方面的信心水平。
在教学干预后立即（P = 0.003）和4个月时（P = 0.001），两组之间的信心水平存在统计学上的显著差异，视频组更具优势。
先前关于使用视频作为教学辅助工具的研究报告了在学生态度和学习成果方面的良好结果。本研究结果证实了这种在本科牙科课程中教授儿科行为技能的教学方式的益处，并且这种益处在4个月时仍然存在。
本研究表明，视频作为一种额外的教学辅助工具，是提高学生在进行局部麻醉时对行为管理技术信心的有效方法。
