COVID-19 ORAL AND MAXILLOFACIAL IMPLICATIONS: AN INTEGRATIVE REVIEW

COVID-19 is a disease caused by the new coronavirus (SARS-CoV-2), identified in Wuhan, China, in December 2019, and declared a pandemic by the World Health Organization in March 2020. Clinical manifestations occur mainly in respiratory system, however some studies have reported extra-pulmonary changes, such as oral and maxillofacial implications. This study aims to verify the possible oral and maxillofacial implications of COVID-19. Therefore, an integrative literature review was carried out. Systematic searches were carried out in SciELO, PubMed, Web of Science, Scopus and Google Scholar from June 6 to 8, 2020. Inclusion criteria were studies that evaluated oral and / or maxillofacial manifestations of COVID-19 and portrayed clinical cases of patients with the disease. Exclusion criteria were studies that were unavailable for reading in full, literature reviews and letters to the editor. Twelve studies were selected, in which the main manifestations were changes in taste and smell, dry mouth, ulcers in the oral mucosa and increase in cervical and submandibular lymph nodes, which may present together with other respiratory symptoms or in isolation. Because of this, the identification of some of these changes can contribute to the early diagnosis of the disease, however more studies are needed to improve the scientific evidence on the subject, to clarify whether part of these changes are manifestations of the disease or a consequence of the immune status of the patient. patient who favors the development of opportunistic infections and neglect of oral hygiene.
