Prevalence of Anxiety in Dental Students during the COVID-19 Outbreak: A Meta-Analysis

Background: Since the onset of the COVID-19 pandemic, the psychological state of university students has been a cause for concern. In particular, odontology students have experienced symptoms of anxiety due to the closure of universities and the suspension of clinical training. Methods: Medline via PubMed was searched for studies on the prevalence of anxiety in dental undergraduates, published from 1 December 2019 to 1 August 2021. Results: A total of fifteen studies were included in this review. Our results show a prevalence of anxiety of 35% reported by dental students, which was independent of gender, response rate or methodological quality. The only significant finding was a lower prevalence of anxiety in studies located in Europe compared to those located in other continents. Conclusions: The results suggest dental students are experiencing significant levels of anxiety during this COVID-19 pandemic and that there seem to be differences between students from different regions of the world. Therefore, it is important to help dental students psychologically as the pandemic situation continues.
