Research progress on oral mucosal manifestations and mechanisms in patients with COVID-19
In 2019,COVID-19 caused by SARS-CoV-2 spread rapidly around the world and triggered a public health crisis,about a quarter of patients have oral mucosal symptoms.These oral mucosal symptoms are caused by a variety of factors,and currently there is no more systematic diagnosis and treatment guideline.Therefore,this paper reviewed the factors and potential mechanisms of oral mucosal manifestations in COVID-19 patients and found that these manifestations were related to SARS-CoV-2 infection of oral mucosal cells and multi-factor mediated oral mucosal immune dysregulation.This will help stomatologists effectively diagnose and treat COVID-19 patients with oral mucosal manifestations.
