Abstract
Severe acute respiratory syndrome coronavirus (SARS-CoV-2) is the virus that causes coronavirus disease 2019, known as Corona virus disease (COVID-19). It is a virus that affects several human organs, including the oral cavity. Human cells are more prone to the entry of SARS-CoV-2 virus due to the extensive expression of Transmembrane Proteases Serine (TMPRSS2 and TMPRSS4) and angiotensin-converting enzyme II (ACE2) receptors in various bodily tissues and organs. Due to the high expression of ACE2 receptors, it is thought that the oral cavity is particularly vulnerable to SARS-CoV-2 infection. As a result, a large number of clinical characteristics of oral manifestations have been reported in COVID-19 cases. The several oral symptoms of COVID-19, their prevalence, and a succinct explanation of their etiology are all reviewed in this article.
