Correlation between the event of the COVID-19 pandemic and symptoms of anxiety, depression and temporomandibular disorder in university students: cross-sectional study

HIGHLIGHTS

  • 78.2% of participants with symptoms of anxiety and 54.5% of participants with symptoms of depression reported a high level of parafunction, while 71.5% of participants who reported painful TMD symptoms had symptoms of anxiety and 52% of depression.

  • The presence of anxiety symptoms was more prevalent than depression among participants with painful symptoms associated with TMD.

  • This study has provided insights into the impact of the COVID-19 pandemic on painful TMD symptoms in university students and the influence of psychological factors such as anxiety and depression.

  • The results observed in this study indicate consequences that may perpetuate after the COVID-19 pandemic period and instigate further studies.

ABSTRACT

BACKGROUND AND OBJECTIVES:

The COVID-19 pandemic has been shown to be a probable aggravator of psychological responses such as anxiety and depression. This study aimed to assess the correlation between symptoms of anxiety and depression during the COVID-19 pandemic and the existence of symptoms associated with temporomandibular dysfunction (TMD) in a Brazilian university population.

METHODS:

This epidemiological, cross-sectional clinical study evaluated its variables of interest using the COVID-19 Fear Scale, Hospital Anxiety and Depression Scale (HADS-A and HADS-D), Diagnostic Criteria for Temporomandibular Dysfunction (DC/TMD) and Oral Behavior Checklist (OBC) questionnaires.

RESULTS:

A total of 373 participants (females = 273) with a mean age of 23.8±5.45 years were included in this study. In addition, 78.2% of participants with anxiety symptoms and 54.5% of participants with depression symptoms reported a high level of TMD-related parafunction (p<0.01). The presence of anxiety symptoms increased the odds of developing intense fear of COVID-19 by 14.9 times (p<0.001) and the odds of developing moderate fear of COVID-19 by 3.5 times (p<0.001). The presence of an intense fear of COVID-19 increased the chances of developing anxiety symptoms by 17.15 times (p<0.001), while the presence of a moderate fear increased these chances by 3.12 times (p<0.001). In addition, the presence of intense (p=0.01) or moderate (p=0.018) COVID-19 fears increased the odds of developing TMD-related pain symptoms by 2.47 and 1.84 times, respectively, in this population.

CONCLUSION:

The presence of painful TMD symptoms was possibly influenced by fear of COVID-19. This, in turn, was related to the presence of anxiety and depression symptoms reported by the target population of this study.
