Abstract
The increased incidence of mucormycosis in post covid-19 is due to steroid induced diabetes mellitus. The commonest presentation is acute invasive fungal sinusitis involving maxillary sinus most commonly followed by invasion to local soft tissues and bone structures. It also involves orbit and brain extending from sinuses. Mandible has no direct communication with any of the para nasal sinuses and involvement is extremely rare and seldom reported. We came across four such cases during post covid-19 mucormycosis epidemic. Poor dentitions, ulcerated mucosa, inoculation during dental procedures are the proposed mode of entry of the fungi into the mandible.
