Oral Manifestations of COVID-19 Infection: An Analytical Cross-Sectional Study

OBJECTIVES: The current COVID-19 pandemic has created a huge impact across the globe. Recent literature has reported the occurrence of varied oral lesions in COVID-19 patients in the form of sporadic case reports. This analytical cross-sectional study was carried out to gauge and understand the pattern of oral lesions in qualitative RT-PCR-confirmed COVID-19 patients. METHODS: A cross-sectional study involves a total of 500 qualitative RT-PCR confirmed, hospitalized COVID-19 patients who were meticulously scanned for any hard and soft tissue lesions developing concomitantly with the disease occurrence. RESULTS: This study included a total of 367 (73.4%) males and 133 (26.6%) female patients with a mean age of 53.46 ± 17.50 years. Almost 51.2% of patients presented with gustatory disturbance, 28% with xerostomia and 15.4% of patients were found to have oral findings like erythema, ulcers, depapillation of tongue. There was a statistically significant correlation between oral manifestations and disease severity (p ≤ 0.001). CONCLUSION: COVID-19 is found to effect oral health with greater probability in patients with severe diseases (SARI) which may be due to disease itself, immune response and lack of motivation for personal hygiene measures.
