Xerostomia (dry mouth) in patients with COVID-19: A case series

Abstract

Introduction: Dry mouth has been reported as a symptom of COVID-19. In this study, xerostomia (dry mouth) was reported in patients with COVID-19. Materials and methods: Dry mouth was assessed in hospitalized patients with COVID-19 daily until all of the dry mouth symptoms resolved. Results: Dry mouth appeared in 60% of cases 3-4 days before as prodromal symptom and in others, simultaneously or 1-2 days after the onset of other symptoms. In most cases, with starting the treatment, dry mouth gradually disappeared. Conclusion: Xerostomia in COVID-19 could occur before the common symptoms. Therefore, it could be hypothesized that it could be used for early diagnosis, quarantine and treatment. As a result, disease transmission might be prevented and the best treatment outcomes could be achieved.
