Since the emergence of the COVID-19 pandemic, there have been many published studies reporting the direct effect of the virus on orofacial structures. In the present study, oral signs and symptoms of 22 hospital-admitted COVID-19 patients were examined and compared to a matching control group. Loss of taste and smell was the most prevalent symptom (65%), followed by oral dryness (45%) and halitosis (30%). The most common oral lesions were candidal infections (68%). Other less common manifestations were oral ulcerations (36%) followed by the appearance of white patches (27.3%). There was a statistically significant association between candidal infection and age in the study group, where the <jats:italic>p<\/jats:italic>-value was 0.008. In the present study, 80% of those who had candida infections were aged 60 years or above. There was no significant association with comorbidities such as diabetes mellitus and hypertension.<\/jats:p>","DOI":"10.3389\/froh.2023.1180017","type":"journal-article","created":{"date-parts":[[2023,8,10]],"date-time":"2023-08-10T11:15:46Z","timestamp":1691666146000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Oral manifestations in hospital-admitted COVID-19 patients: a case control study"],"prefix":"10.3389","volume":"4","author":[{"given":"Sana","family":"Alhamed","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suad","family":"Aljohani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,8,10]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2530","DOI":"10.1111\/odi.13857","article-title":"Oral manifestations accompanying and related to COVID-19: overlooking the obvious","volume":"28","author":"Anaya-Saavedra","year":"2021","journal-title":"Oral Dis"},{"key":"B2","doi-asserted-by":"publisher","first-page":"549","DOI":"10.4317\/medoral.24461","article-title":"Non-specific oral and cutaneous manifestations of coronavirus disease 2019 in children","volume":"26","author":"Bardellini","year":"2021","journal-title":"Med Oral Patol Oral Cir Bucal"},{"key":"B3","doi-asserted-by":"publisher","first-page":"e45","DOI":"10.1016\/j.oooo.2020.07.014","article-title":"Oral lesions in patients with SARS-CoV-2 infection: could the oral cavity be a target organ?","volume":"131","author":"Brand\u00e3o","year":"2021","journal-title":"Oral Surg Oral Med Oral Pathol Oral Radiol"},{"key":"B4","doi-asserted-by":"publisher","first-page":"e2226","DOI":"10.1002\/rmv.2226","article-title":"COVID-19 and oral diseases: crosstalk, synergy or association?","volume":"3","author":"Brandini","year":"2021","journal-title":"Rev Med Virol"},{"key":"B5","year":"2021"},{"key":"B6","doi-asserted-by":"publisher","first-page":"e143","DOI":"10.1016\/j.jaad.2020.11.034","article-title":"The oral cavity cannot be forgotten in the COVID-19 era: is there a connection between dermatologic and oral manifestations?","volume":"84","author":"Bemquerer","year":"2021","journal-title":"J Am Acad Dermatol"},{"key":"B7","doi-asserted-by":"publisher","first-page":"722","DOI":"10.1177\/0194599820934380","article-title":"Olfactory and oral manifestations of COVID-19: sex-related symptoms-A potential pathway to early diagnosis","volume":"163","author":"Biadsee","year":"2020","journal-title":"Otolaryngol Head Neck Surg"},{"key":"B8","doi-asserted-by":"publisher","first-page":"555","DOI":"10.1111\/scd.12520","article-title":"Oral mucosal lesions in patients with SARS-CoV-2 infection.
