Abstract

Intraoral frostbite as such, is an unusual occurrence. Careful literature review revealed rare cases of intraoral frostbite, attributed to intentional inhalational abuse of fluorinated hydrocarbons, dry ice, liquid nitrogen etc. Hypothermal injuries of the gastric mucosa caused by ingestion of liquid nitrogen have been reported but none of these patients suffered from any direct injury affecting the oral mucosa. Here, we report the first case of intraoral frostbite causing injury to the oral mucosal tissues due to the direct contact of liquid nitrogen, highlighting the mechanism of the injury. Liquid nitrogen is being used increasingly in creating cuisines with a smoky effect for aesthetic purposes. The use of liquid nitrogen in the food and beverage industry does not seem to require any specialized training and there are no regulations controlling the sales of this agent.
