Abstract

Background: Oral symptoms may serve as the initial indications of COVID-19 prior to the onset of systemic symptoms. An understanding of these indicators facilitates rapid diagnosis and early detection. Objective: This case study presents early oral symptoms observed in 15 patients subsequently diagnosed with COVID19. Materials and Method: The cases were organised based on the form of oral lesions. The clinical features, duration of symptoms, treatment regimens, and outcomes were documented. Results: The most frequently observed oral lesions included ulcerative lesions (n=6), stomatitis (n=4), dysgeusia/ageusia (n=2), angular cheilitis (n=2), and oral candidiasis (n=1). Lesions, frequently painful, initially manifested two to six days prior to the onset of systemic COVID-19 symptoms. The treatment involved supportive care, topical corticosteroids, antiseptics, antifungals, and symptomatic therapy. Dysgeusia persisted for up to three weeks, whereas most lesions resolved within ten to fourteen days. No long-term complications or recurrences were observed. Conclusion: Initial oral manifestations may be valuable clinical indicators for diagnosing COVID-19. Practitioners should be knowledgeable about these presentations to facilitate early identification and treatment.
