SARS-CoV-2 and Oral Ulcers; a Causative Agent or a Predisposing Factor?

Earlier reports on COVID-19 have reported certain orofacial manifestations like taste loss and salivary gland infection (Dar-Odeh et al, 2020). More recently, two studies from Spain and France reported oral ulcerative lesions in COVID-19 patients ( Chaux-Bodard et al, 2020; Carreras- Presas et al, 2020). The study from Spain included three patients. The first two cases (males) were suspected cases of COVID-19 as testing was not done for them. Intraorally, they had oral ulcers affecting the hard palate unilaterally in the anatomic area innervated by greater palatine nerve.
