RESEARCH OF MANIFESTATION OF THE ORAL MUCOSA IN COVID-19

Abstract

The oral cavity is one of the main gates for coronavirus (SARS-CoV-2); the oral cavity also suffers greatly from this infection, because it is one of the most vulnerable places. In addition, since the salivary glands can serve as a reservoir for viruses and support their release into the external environment, it was concluded that saliva, as a component of oral fluid, can play an important role in the spread of coronavirus infection. This is mainly due to the ACE-2 receptor, which have a high level of expression in the keratinized surface epithelial cells of the oral mucosa, especially in the epithelial cells of the dorsal part of the tongue, tonsils, vocal cords, salivary glands and sinuses, due to which the virus replicates in and causes both oral lesions and oral symptoms mouth After entering the cell, the virus delays the response of the immune system, allowing the infection to progress, and it becomes much more difficult to fight it. Accordingly, due to the relatively high level of COVID-19-associated complications, timely diagnosis of clinical forms, including high-risk patients with prognosis their clinical course and the selection of drug treatment appropriate to the severity of the clinical course remain quite complex and controversial issues. It was emphasized that in some cases oral symptoms may be the initial or only sign of disease, and dentists should take this into account when performing a thorough clinical examination of the oral cavity.
