The purpose was to analyse the associations between dental and trait anxiety, fear of COVID-19 and the duration and frequency of spontaneous hand-to-face contact (self-contact).
A cross-sectional design was carried out with 128 adult patients from four dental clinics in Madrid, during the confinement, from March 15 to May 15. The patients' movements in the waiting room were monitored with Microsoft Kinect Software, also completed the Trait anxiety subscale of the STAI, the COVID-19 Fear and the S-DAI questionnaire.
Associations were observed between the duration and frequency of facial, mask and eye contact with trait anxiety and dental fear was determined only by the frequency of this self-contact. Trait anxiety is associated with dental anxiety and with fear of COVID-19. Although facial self-contact is higher in women, it also rises in men as dental fear increases. Moreover, dental anxiety is a good predictor of trait anxiety and the incidence of facial self-contact.
Understanding the possible associations between biopsychosocial factors, such as trait anxiety, dental anxiety and self-contact is important. It may help to prevent the spread of COVID-19 in the population as well as enabling the formulation of effective interventions to improve oral health care through the implementation of dental care programmes.
目的在于分析牙源性焦虑、对 COVID-19 的恐惧与自发的手接触面部（自我接触）的持续时间和频率之间的关系。
采用横断面设计，在马德里四家牙科诊所对 128 名成年患者进行研究，研究时间为 3 月 15 日至 5 月 15 日隔离期间。通过 Microsoft Kinect 软件监测患者在候诊室的活动情况，同时还完成了状态特质焦虑量表特质焦虑分量表、COVID-19 恐惧量表和 S-DAI 问卷的填写。
观察到面部、口罩和眼部接触的持续时间和频率与特质焦虑之间存在关联，而口腔恐惧仅与自我接触的频率有关。特质焦虑与口腔焦虑和对 COVID-19 的恐惧有关。尽管女性的面部自我接触频率更高，但随着口腔恐惧的增加，男性的这种接触频率也会上升。此外，口腔焦虑是特质焦虑和面部自我接触发生率的一个良好预测指标。
了解特质焦虑、口腔焦虑和自我接触等生物心理社会因素之间的可能关联很重要。这有助于防止 COVID-19 在人群中的传播，并通过实施牙科保健计划来制定有效的干预措施，以改善口腔保健。
