Oral manifestations of covid-19

Abstract

COVID-19 is caused by the SARS-CoV-2 virus and proved to be a challenge since there was little knowledge about this disease. Several viral infections can affect the oral cavity and because of this is fundamental the study of this disease and whether oral manifestations could appear in an oral cavity. This work aims to review the literature on what is in the scientific articles of the oral manifestations of COVID-19 since the recognition of the existence of the pandemic.

The effect of artificial saliva on the control of dry mouth: a semi-experimental study on COVID-19 patients under Non-invasive mechanical ventilation

“…In Baiadsee et al 's study, 72% of patients with COVID-19 complained of dry mouth [25]. In addition, infection with COVID-19 is also associated with changes in saliva secretion and dry mouth, among which patients with COVID-19 admitted to the hospital and undergoing non-invasive and invasive mechanical ventilation are exposed to a severe decrease in saliva and dry mouth [10], these findings align with the present study since the patients in the test and control groups had dry mouths before the intervention.…”

“…In patients with COVID-19, dry mouth occurs due to changes in the quantity and composition of oral saliva. This disease is associated with oral manifestations caused by direct viral infection, simultaneous infections, drug reactions, and stress; other symptoms may include oral soft tissue ulcers, gingivitis, plaques, erythema, and changes in salivary glands and oral nerves [10]. On the other hand, putting patients with COVID-19 under non-invasive mechanical ventilation increases the symptoms of dry mouth and ulcers in these patients [11].…”
