牙科焦虑会随着治疗过程的展开而变化，然而牙科虚拟现实（VR）通常提供持续的分散注意力或放松。我们研究了如何将支持与特定的模拟牙科事件相协调。利益相关者访谈（N=36）、与三位复诊牙医的参与式设计，以及无干预原型的患者走查（N=12）共同确定了五个焦虑事件和一个干预模块框架。基于认知脆弱性和情绪调节理论，我们实现了一个标准化的基于事件的VR系统，该系统具有预定义的事件-模块分配以及共享代理和安全控制。一项随机研究（N=24）将干预包与无干预VR进行了比较。调整后的干预组减去对照组差异在各事件中平均为-12.83 VAS-A分（95%置信区间[-24.42, -1.70]）。生理、行为和定性测量为参与者的体验提供了背景信息。研究结果为模拟牙科VR中及时、可理解的支持和令人安心的社会存在提供了信息；这些发现涉及完整干预包，而非单个模块或临床有效性。
英文摘要
Dental anxiety can change as a procedure unfolds, yet dental virtual reality (VR) commonly provides continuous distraction or relaxation. We investigate how support can be coordinated with specific simulated dental events. Stakeholder interviews (N=36), participatory design with three returning dentists, and patient walkthroughs of a no-intervention prototype (N=12) informed five Anxiety Events and an intervention-module framework. Drawing on cognitive vulnerability and emotion regulation, we implemented a standardized event-contingent VR system with predefined event-module assignments and shared agency and safety controls. A randomized study (N=24) compared the intervention package with no-intervention VR. The adjusted intervention-minus-control difference averaged -12.83 VAS-A points across events (95% CI [-24.42, -1.70]). Physiological, behavioural, and qualitative measures contextualized participants' experiences. The findings inform timely, comprehensible support and reassuring social presence in simulated dental VR; they concern the complete package rather than individual modules or clinical effectiveness.
