Abstract：
UNASSIGNED: To evaluate possible temporomandibular disorders (TMD) symptoms that may occur due to mask use in dentists during the coronavirus disease-2019 pandemic period and identify potentially effective factors.
UNASSIGNED: An online questionnaire consisting of three parts was sent to dentists and clinical dental students. The first part included questions regarding sociodemographic information. In the second part, questions were asked to evaluate stress levels, TMD symptoms, and treatment of TMD, if any, before (T0) and during the pandemic (T1). In the last part, professional mask choice, mask-related parafunctional movements, and breathing patterns while wearing a mask were evaluated.
UNASSIGNED: TMD symptoms and stress levels were significantly higher at T1. An increase in mouth breathing and mask-related parafunctional movements was reported during the use of N95 masks compared with daily life in dentists whose professional mask selection was an N95 respirator. The change in temporomandibular joints pain and muscle pain at rest between T0 and T1 was higher in those whose professional mask choice was N95 respirators than in those who chose to wear one surgical mask.
UNASSIGNED: The increase in mouth breathing and mask-related parafunctional movements during the use of N95 respirators may increase TMD.

摘要：
■评估在冠状病毒疾病-2019大流行期间由于牙医使用口罩而可能发生的颞下颌关节紊乱病（TMD）症状，并确定潜在的有效因素。
■向牙医和临床牙科学生发送了由三部分组成的在线问卷。第一部分包括有关社会人口统计信息的问题。在第二部分,被问到评估压力水平的问题，TMD症状,和TMD的治疗，如果有的话,大流行前(T0)和大流行期间(T1)。在最后一部分,专业面膜选择,面具相关的超功能运动，并评估了戴口罩时的呼吸模式。
■TMD症状和压力水平在T1时显着升高。据报道，与专业选择N95呼吸器的牙医的日常生活相比，使用N95口罩期间口腔呼吸和与口罩相关的功能异常运动有所增加。在T0和T1之间休息时颞下颌关节疼痛和肌肉疼痛的变化在专业面罩选择为N95呼吸器的人中比选择佩戴一个外科面罩的人高。
■在使用N95呼吸器期间，口腔呼吸和与面罩相关的功能异常运动的增加可能会增加TMD。
