The primary objective was to determine peritraumatic distress among orthodontic patients during the COVID-19 lockdown. And the secondary objective was to determine the relationship between peritraumatic distress in relation to different appliance types.
Cross-sectional study.
Primary hospital between May and June 2022.
Patients in the process of orthodontic treatment, able to read Mandarin online, provided informed consent for the use of the data recorded and completed the questionnaire within a reasonable time.
None.
The demographic information and orthodontic urgencies were collected using online questionnaires. The peritraumatic distress symptoms were assessed by the COVID-19 Peritraumatic Distress Index (CPDI). The temporomandibular joint (TMJ) pain was evaluated using a Visual Analogue Scale.
A total of 480 participants were enrolled, including 331 with fixed appliances, 131 with clear aligners and 18 with removable appliances. For all participants, the median CPDI score was 12 (4, 19). Higher CPDI scores were observed in participants with urgency (14 (6, 21) vs 8 (2, 15), p<0.001), participants aged ≥18 years (15 (6, 23) vs 8 (2, 15), p<0.001) and participants with TMJ pain (15 (8, 24) vs 11 (3, 18), p<0.001). Linear regression showed that age >18 years (β=0.271, p<0.001), TMJ pain (β=0.169, p<0.001) and urgency (β=0.144, p=0.001) were independently associated with the mean CPDI score.
The study suggested that during catastrophic events such as the COVID-19 lockdown, orthodontic urgencies may exacerbate patients' peritraumatic distress, especially among adult patients and those who suffer from TMJ pain.
主要目的是确定新冠疫情封锁期间正畸患者的创伤后应激反应。次要目的是确定不同矫治器类型与创伤后应激反应之间的关系。
横断面研究。
2022年5月至6月期间的基层医院。
正在接受正畸治疗、能在线阅读中文、同意使用所记录数据并在合理时间内完成问卷的患者。
无。
使用在线问卷收集人口统计学信息和正畸紧急情况。通过新冠疫情创伤后应激反应指数（CPDI）评估创伤后应激症状。使用视觉模拟量表评估颞下颌关节（TMJ）疼痛。
共纳入480名参与者，其中331名使用固定矫治器，131名使用隐形矫治器，18名使用活动矫治器。所有参与者的CPDI得分中位数为12（4，19）。在有紧急情况的参与者（14（6，21）对8（2，15），p<0.001）、年龄≥18岁的参与者（15（6，23）对8（2, 15），p<0.001）和有TMJ疼痛的参与者（15（8，24）对11（3，18），p<0.001）中观察到更高的CPDI得分。线性回归显示，年龄>18岁（β=0.271，p<0.001）、TMJ疼痛（β=0.169，p<0.001）和紧急情况（β=0.144，p=0.001）与CPDI平均得分独立相关。
该研究表明，在新冠疫情封锁等灾难性事件期间,正畸紧急情况可能会加剧患者的创伤后应激反应，尤其是成年患者和患有TMJ疼痛的患者。
