| Abstract | Background Early studies have highlighted the possible development of dysgeusia and anosmia in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and these manifestations should be considered a potential indication of coronavirus disease 19 (COVID-19). As potential contributors to these symptoms, dentists should perform careful oral and oropharyngeal examinations and document suspicious oral lesions in patients with COVID-19, especially in those who complain of loss of taste and smell. The study’s objective was to assess the prevalence of oral manifestations among ambulatory unvaccinated symptomatic patients with suspected COVID-19 during the acute phase of the disease. Methods This cross-sectional study evaluated oral manifestations in adults (aged≥18 years) with suspected and confirmed SARS-CoV-2 infection. Chi-square and Fisher’s exact tests were used to compare data between the groups (rRT-PCR-positive and rRT-PCR-negative patients). Results One hundred thirty-six participants were included. Most were female (n=79; 58.1%), with a mean age of 39.53 (±14.17) years. Of these, 54 (39.7%) had a positive rRT-PCR test, and 82 (60.3%) had negative rRT-PCR results. Oral manifestations were observed in 40 participants (74.1%) in the rRT-PCR-positive group and 67 participants (81.7%) in the rRT-PCR-negative group. The most common oral manifestations were xerostomia (n=85; 62.5%) and dysgeusia/ageusia (n=57; 41.9%). Different rates of gingivitis (n=12; 22.2% vs. n=5; 6.1%; p=0.005) and halitosis (n=7; 13.0% vs. n=1; 1.2%; p=0.007) were observed between the rRT-PCR-positive and -negative groups, respectively. Mouth ulcers, glossitis, tongue coating, and petechiae were reported in both groups without significant differences. Conclusions A high prevalence of oral manifestations was observed in symptomatic patients with suspected or confirmed COVID-19. Clinical Relevance This study highlights the importance of routine oral examinations by dentists as part of the multidisciplinary care of COVID-19 patients. | en_US |
