Manifestações bucais associadas ao covid 19

Abstract

At the end of 2019, the eyes of the world were turned to the Chinese province of Wuhan, the epicenter of the virulent pandemic caused by Sars-Cov-2. Since then, the multisystemic morbidity described as Covid 19 has become the focus of numerous researches in the areas of action of the health sciences, with the objective of providing greater dissemination of knowledge for health promotion in different populations. In view of this, this study aims to identify whether there is a correlation between oral lesions and infection by Sars-Cov-2, and if so, to present the main oral changes associated with infection caused by Covid19. For this, a literary review of indexed scientific articles on the subject in question was carried out in a database of virtual libraries. However, it was found that recent research associates the diagnosis of manifestations of oral and perioral lesions with involvement by Covid 19; among these, the most prevalent are: multiple ulcerations with or without necrosis, herpes, candidiasis, bullous angina, spontaneous oral hemorrhage, petechiae, papillary erythema, and papillary hyperplasia. Researchers correlate such incidence to the pathophysiological mechanism of this viral proliferation; being the oral region one of the first areas to be affected, due to the favorable conditions for viral replication. Therefore, the oral cavity is one of the first regions to manifest the aggravation of the disease. Some studies condition this picture on the hypothesis that oral lesions may be secondary to thrombosis in subepithelial and deep vessels; thus, the incidence of early lesions could be considered a marker in the Covid-19 worsening curve, other lines of research associate lesions with conditions of immunosuppression, but further studies are needed to show such condition.
