SARS-CoV-2, spreads through respiratory droplets from an infected person and causes a respiratory disease called Covid-19 (Coronavirus Disease, 2019). Its clinical behavior is variable and manifests with mild or moderate symptoms, and may develop a severe respiratory infection. The oral cavity has been identified as one of the gateways for SARS-CoV-2, and its possible role as an aggravating factor in the infectivity and progression of viral infection has been controversial. A retrospective cohort study was carried out with data obtained from 274 medical records of patients with COVID-19. Data was collected on the admission of the patient, with seven and fourteen days to analyze the occurrence of oral changes and relate them to the severity of the infection. A total of 154 patients with oral alterations and 120 without alterations were found. Of the 154 patients who presented oral changes on admission, 39 achieved remission within 7 days, 54 patients achieved remission within 14 days, and 61 maintained oral changes until the end of the study. Of the 120 patients who did not present oral changes on admission, only 2 developed oral changes within 7 days and these died. The most frequent oral alteration was an ulcer in the three collection times (T0: 43.8%, T1: 33.6% and T2: 21.2%). The most prevalent abnormal exam analyses among patients were red blood cells, platelets, leukocytes, bleeding time, TGP, TGO, albumin, creatinine, CRP, urea, d-dimer, and leukocyte-lymphocyte ratio. No predictors were observed for the development of oral alterations in patients with COVID 19. Alterations in the oral mucosa were observed in most patients with COVID-19 analysed in this study. There was no association between comorbidities and the presence of oral lesions in the patients evaluated. Prognostic factors were evaluated by Cox's multivariate analysis, which determined that they did not use medication for the digestive system and for metabolism (HR: 2.18; 95%CI: 1.13- 4.22) and did not have systemic arterial hypertension (HR: 1.78; 95%CI: 1.13-2.79), these are prognostic factors for remission of oral changes in patients with COVID-19.Acesso AbertoInfecções por CoronavírusManifestações bucaisAssistência hospitalardoctoralThesis
