Assessment of oral tissue alterations in patients diagnosed with SARS-CoV-2.

Abstract

The aim of this study was to investigate oral mucosal changes in patients with confirmed moderate-scale severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We analyzed 85 COVID-19 patients (50 males, 35 females) with an average age of 53.6 years, treated at the prehospital infectious disease center and Aldent University Clinic in Tirana, Albania, from May 2021 to June 2022. Elevated C-reactive protein levels were observed in 82 patients (±44.20), with 20 patients showing significant fibrinogen increase (mean ± 5.85 g/L), and 22 patients having elevated D-Dimer (mean ± 336.6 mg/mL). Despite the absence of anticoagulant history, 13 patients exhibited bleeding. Xerodermia, xerostomia, and angular cheilitis were noted, with 41 patients displaying angular cheilitis. In 82 patients, oral mucosal and tongue examinations revealed color changes from white to bright yellow, with brown edema. Pigmentation in the fixed gingiva of upper and lower front teeth was observed in 35 patients. Oral mucosal changes during COVID-19 appear more influenced by drug treatment and disease progression than the infection itself, suggesting that secondary factors play a significant role. Despite the oral cavity's potential for viral entry, these changes seem connected to other underlying causes.
