Abstract

Background: Novel coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) shows various respiratory symptoms of varying severity. However, the virus can affect any organ in the body. Understanding about the oral manifestations would be helpful in early diagnosis and treatment of this disease. Aim: The aim of the study was to understand the oral manifestations associated with SARS-CoV-2 infection using a self-designed questionnaire. Objectives: To understand the impact of SARS-CoV-2 infection in oral cavity so that early treatment can be provided. Materials and Methods: The study was done on 100 COVID-19-positive dental students above 18 years with positive RT-PCR reports. Participants were asked to fill the questionnaire after doing a self-examination of the oral cavity throughout the course of infection. Result: Fifty-five per cent of patients experienced oral manifestations during the course of infection. Various oral manifestations including xerostomia, dysphagia, altered taste sensation, burning sensation, redness of oral mucosa, halitosis, blisters, and white patches were reported by the participants. Conclusion: Various oral manifestations are seen in COVID-19-positive patients hence SARS-CoV-2 infection has a significant effect on oral epithelium.
