The ongoing COVID-19 pandemic postponed routine follow-up visits of many orthodontic patients, which compromised their treatment process and mental states. This study was aimed to assess orthodontic emergency occurrence and psychological states of Chinese orthodontic patients during this pandemic.
Orthodontic patients in China were invited to answer an anonymous online questionnaire from February 20, 2020 to March 5, 2020, when routine dental care was suspended in China. The questionnaire included self-assessment of oral hygiene and compliance, orthodontic emergencies, perceptions and feelings about COVID-19 and anxiety self-rating scale, etc. Collected data was statistically analyzed with Chi-square, independent t test and univariable generalized estimating equations regression analysis.
A total of 1078 respondents (292 male; 786 female) from 30 provinces of China were included in this study. About one-third (33.67%) of patients reported that they encountered orthodontic problems during the pandemic. Patients with clear aligners reported fewer orthodontic problems than those with fixed appliances or removable appliances. Female patients, elder patients and patients who encountered orthodontic emergencies were more anxious than other patients.
The compliance and occurrence of orthodontic emergencies differed in patients with different orthodontic appliances. Patients with orthodontic emergencies exhibited higher anxiety states.
持续的 COVID-19 大流行推迟了许多正畸患者的常规随访，这影响了他们的治疗进程和心理状态。本研究旨在评估中国正畸患者在此次大流行期间的正畸急症发生情况和心理状态。
本研究于 2020 年 2 月 20 日至 3 月 5 日期间，邀请中国的正畸患者回答匿名在线问卷，当时中国暂停了常规牙科护理。问卷内容包括自我评估口腔卫生和遵医行为、正畸急症、对 COVID-19 的认知和感受以及焦虑自评量表等。采用卡方检验、独立 t 检验和单变量广义估计方程回归分析对收集的数据进行统计学分析。
本研究共纳入来自中国 30 个省的 1078 名受访者（男性 292 名，女性 786 名）。约三分之一（33.67%）的患者报告在大流行期间遇到了正畸问题。与固定矫治器或可摘矫治器相比，使用透明矫治器的患者报告的正畸问题较少。女性患者、年龄较大的患者和遇到正畸急症的患者比其他患者更焦虑。
不同正畸矫治器的患者遵医行为和正畸急症的发生情况存在差异，遇到正畸急症的患者表现出更高的焦虑状态。
