ABSTRACT

Dental barotrauma has been called aerodontalgia or barodontalgia when it is applied to altitude exposure. ere are three common presentations of dental barotrauma.

In the rst presentation, gas spaces may exist in the roots of infected teeth, along dying nerves, in necrotic or inammatory areas of the pulp, alongside or associated with llings that were poorly inserted or have undergone secondary erosion, jawbone cysts, impacted teeth or other oral maxillofacial disease. e gas may enter around the edge of the lling, adjacent to the tooth or through microfractures of the enamel and dentine (Figure 9.1).
