Oral manifestations of COVID‐19 patients: An online survey of the Egyptian population

Abstract

Abstract Objectives This pilot survey aims to study the oral manifestations associated with COVID‐19 infection and report the prevalence of oral signs and symptoms in COVID‐19 patients. Materials and Methods From May 15 to June 10, 2020, we used an online questionnaire containing the oral manifestations that are expected to be associated with the COVID‐19 infection. Adults in our survey who have been diagnosed with COVID‐19 positive were confirmed with reverse transcriptase PCR (RT‐PCR), and isolated in various hospitals in Cairo, Egypt. Results This pilot study included 58 (53.4% males and 46.6% females) COVID‐19 patients ages 18–46 years, and 13 (22.4%) were healthcare workers. Our results showed that 67.2% of the patients had at least one manifestation related to the oral cavity and salivary glands, and 32.8% (n = 19) did not have any symptoms associated with the oral cavity. The highest prevalence symptoms were dry mouth 39.7% (n = 23), gustatory dysfunction as 34.5% (n = 20) loss of salt sensation, 29.3% (n = 17) loss of sweet sensation, and 25.9% (n = 15) altered food taste, while the least prevalent symptoms were tongue redness 8.8% (n = 5), and gingival bleeding 7% (n = 4). The most frequently associated symptoms were loss of salt and sweetness, as reported by 27.6% of the participants. However, there was no significant association between the incidence of oral symptoms and demographic data (age, gender, or job) of the patients (p > 0.05). Conclusions Based on limited data, COVID‐19 significantly impacts the oral cavity and salivary glands, as salivary gland‐related symptoms and taste disorders are highly prevalent in COVID‐19 patients.
